This chapter describes MySQL Connectors, drivers that provide connectivity to the MySQL server for client programs. There are currently five MySQL Connectors:
-
Connector/ODBC provides driver support for connecting to a MySQL server using the Open Database Connectivity (ODBC) API. Support is available for ODBC connectivity from Windows, Unix and Mac OS X platforms.
-
Connector/NET enables developers to create .NET applications that use data stored in a MySQL database. Connector/NET implements a fully-functional ADO.NET interface and provides support for use with ADO.NET aware tools. Applications that want to use Connector/NET can be written in any of the supported .NET languages.
-
The MySQL Visual Studio Plugin works with Connector/NET and Visual Studio 2005. The plugin is a MySQL DDEX Provider, which means that you can use the schema and data manipulation tools within Visual Studio to create and edit objects within a MySQL database.
-
Connector/J provides driver support for connecting to MySQL from a Java application using the standard Java Database Connectivity (JDBC) API.
-
Connector/MXJ is a tool that enables easy deployment and management of MySQL server and database through your Java application.
-
Connector/PHP is a Windows-only connector for PHP that provides the mysql and mysqli extensions for use with MySQL 5.0.18 and later.
For information on connecting to a MySQL server using other languages and interfaces than those detailed above, including Perl, Python and PHP for other platforms and environments, please refer to the Chapter 28, APIs and Libraries chapter.
29.1. MySQL Connector/ODBC
The MySQL Connector/ODBC is the name for the family of MySQL ODBC drivers (previously called MyODBC drivers) that provide access to a MySQL database using the industry standard Open Database Connectivity (ODBC) API. This reference covers Connector/ODBC 3.51 and Connector/ODBC 5.1. Both releases provide an ODBC compliant interface to MySQL Server.
MySQL Connector/ODBC provides both driver-manager based and native interfaces to the MySQL database, which full support for MySQL functionality, including stored procedures, transactions and, with Connector/ODBC 5.1, full Unicode compliance.
For more information on the ODBC API standard and how to use it, refer to http://support.microsoft.com/kb/110093.
The application development part of this reference assumes a good working knowledge of C, general DBMS knowledge, and finally, but not least, familiarity with MySQL. For more information about MySQL functionality and its syntax, refer to http://dev.mysql.com/doc/.
Typically, you need to install Connector/ODBC only on Windows machines. For Unix and Mac OS X you can use the native MySQL network or named pipe to communicate with your MySQL database. You may need Connector/ODBC for Unix or Mac OS X if you have an application that requires an ODBC interface to communicate with the database. Applications that require ODBC to communicate with MySQL include ColdFusion, Microsoft Office, and Filemaker Pro.

29.1.1. Connector/ODBC Versions
There are currently two version of Connector/ODBC available:
-
Connector/ODBC 5.1, currently in Beta status, is a partial rewrite of the of the 3.51 code base and is designed to work all versions of MySQL from 4.1. Connector/ODBC 5.1 will be a complete implementation of the ODBC Core interface,plus more Level 1 and Level 2 functionality of the ODBC specification than that currently supported by Connector/ODBC 3.51. See Section 29.1.2.1, “Connector/ODBC Roadmap”.
Connector/ODBC 5.1 also includes the following changes and improvements over the 3.51 release:
-
Improved support on Windows 64-bit platforms.
-
Full Unicode support at the driver level. This includes support for the SQL_WCHAR datatype, and support for Unicode login, password and DSN configurations. For more information,. see Microsoft Knowledgebase Article #716246.
-
Support for the SQL_NUMERIC_STRUCT datatype, which provides easier access to the precise definition of numeric values. For more information, see Microsoft Knowledgebase Article #714556
-
Native Windows setup library. This replaces the Qt library based interface for configuring DSN information within the ODBC Data Sources application.
-
Support for the ODBC descriptor, which improves the handling and metadata of columns and parameter data. For more information, see Microsoft Knowledgebase Article #716339.
-
Connector/ODBC 3.51 is the current release of the 32-bit ODBC driver, also known as the MySQL ODBC 3.51 driver. Connector/ODBC 3.51 has support for ODBC 3.5x specification level 1 (complete core API + level 2 features) in order to continue to provide all functionality of ODBC for accessing MySQL.
The manual for versions of Connector/ODBC older than 3.51 can be located in the corresponding binary or source distribution. Please note that versions of Connector/ODBC earlier than the 3.51 revision were not fully compliant with the ODBC specification.
Note
Development on Connector/ODBC 5.0 was stopped due to development issues. Connector/ODBC 5.1 is now the current development release.
Note
From this section onward, the primary focus of this guide is the Connector/ODBC 3.51 and Connector/ODBC 5.1 drivers.
Note
Version numbers for MySQL products are formatted as X.X.X. However, Windows tools (Control Panel, properties display) may show the version numbers as XX.XX.XX. For example, the official MySQL formatted version number 5.0.9 may be displayed by Windows tools as 5.00.09. The two versions are the same; only the number display format is different.
29.1.2. Connector/ODBC Introduction
ODBC (Open Database Connectivity) provides a way for client programs to access a wide range of databases or data sources. ODBC is a standardized API that allows connections to SQL database servers. It was developed according to the specifications of the SQL Access Group and defines a set of function calls, error codes, and data types that can be used to develop database-independent applications. ODBC usually is used when database independence or simultaneous access to different data sources is required.
For more information about ODBC, refer to http://support.microsoft.com/kb/110093.
29.1.2.1. Connector/ODBC Roadmap
Connector/ODBC 5.1 is currently in development and will be a complete implementation of the ODBC Core interface,plus more Level 1 and Level 2 functionality of the ODBC specification than that currently supported by Connector/ODBC 3.51.
The following functionality was added or changed as part of 5.1:
The following functionality will be added in a version after 5.1:
29.1.2.2. General Information About ODBC and Connector/ODBC
Open Database Connectivity (ODBC) is a widely accepted application-programming interface (API) for database access. It is based on the Call-Level Interface (CLI) specifications from X/Open and ISO/IEC for database APIs and uses Structured Query Language (SQL) as its database access language.
A survey of ODBC functions supported by Connector/ODBC is given at Section 29.1.6.1, “Connector/ODBC API Reference”. For general information about ODBC, see http://support.microsoft.com/kb/110093.
29.1.2.2.1. Connector/ODBC Architecture
The Connector/ODBC architecture is based on five components, as shown in the following diagram:
-
Application:
The Application uses the ODBC API to access the data from the MySQL server. The ODBC API in turn uses the communicates with the Driver Manager. The Application communicates with the Driver Manager using the standard ODBC calls. The Application does not care where the data is stored, how it is stored, or even how the system is configured to access the data. It needs to know only the Data Source Name (DSN).
A number of tasks are common to all applications, no matter how they use ODBC. These tasks are:
-
Selecting the MySQL server and connecting to it
-
Submitting SQL statements for execution
-
Retrieving results (if any)
-
Processing errors
-
Committing or rolling back the transaction enclosing the SQL statement
-
Disconnecting from the MySQL server
Because most data access work is done with SQL, the primary tasks for applications that use ODBC are submitting SQL statements and retrieving any results generated by those statements.
-
Driver manager:
The Driver Manager is a library that manages communication between application and driver or drivers. It performs the following tasks:
-
Resolves Data Source Names (DSN). The DSN is a configuration string that identifies a given database driver, database, database host and optionally authentication information that enables an ODBC application to connect to a database using a standardized reference.
Because the database connectivity information is identified by the DSN, any ODBC compliant application can connect to the data source using the same DSN reference. This eliminates the need to separately configure each application that needs access to a given database; instead you instruct the application to use a pre-configured DSN.
-
Loading and unloading of the driver required to access a specific database as defined within the DSN. For example, if you have configured a DSN that connects to a MySQL database then the driver manager will load the Connector/ODBC driver to enable the ODBC API to communicate with the MySQL host.
-
Processes ODBC function calls or passes them to the driver for processing.
-
Connector/ODBC Driver:
The Connector/ODBC driver is a library that implements the functions supported by the ODBC API. It processes ODBC function calls, submits SQL requests to MySQL server, and returns results back to the application. If necessary, the driver modifies an application's request so that the request conforms to syntax supported by MySQL.
-
DSN Configuration:
The ODBC configuration file stores the driver and database information required to connect to the server. It is used by the Driver Manager to determine which driver to be loaded according to the definition in the DSN. The driver uses this to read connection parameters based on the DSN specified. For more information, Section 29.1.4, “Connector/ODBC Configuration”.
-
MySQL Server:
The MySQL database where the information is stored. The database is used as the source of the data (during queries) and the destination for data (during inserts and updates).
29.1.2.2.2. ODBC Driver Managers
An ODBC Driver Manager is a library that manages communication between the ODBC-aware application and any drivers. Its main functionality includes:
-
Resolving Data Source Names (DSN).
-
Driver loading and unloading.
-
Processing ODBC function calls or passing them to the driver.
Both Windows and Mac OS X include ODBC driver managers with the operating system. Most ODBC Driver Manager implementations also include an administration application that makes the configuration of DSN and drivers easier. Examples and information on these managers, including Unix ODBC driver managers are listed below:
-
Microsoft Windows ODBC Driver Manager (odbc32.dll), http://support.microsoft.com/kb/110093.
-
Mac OS X includes ODBC Administrator, a GUI application that provides a simpler configuration mechanism for the Unix iODBC Driver Manager. You can configure DSN and driver information either through ODBC Administrator or through the iODBC configuration files. This also means that you can test ODBC Administrator configurations using the iodbctest command. http://www.apple.com.
-
unixODBC Driver Manager for Unix (libodbc.so). See http://www.unixodbc.org, for more information. The unixODBC Driver Manager includes the Connector/ODBC driver 3.51 in the installation package, starting with version unixODBC 2.1.2.
-
iODBC ODBC Driver Manager for Unix (libiodbc.so), see http://www.iodbc.org, for more information.
29.1.3. Connector/ODBC Installation
You can install the Connector/ODBC drivers using two different methods, a binary installation and a source installation. The binary installation is the easiest and most straightforward method of installation. Using the source installation methods should only be necessary on platforms where a binary installation package is not available, or in situations where you want to customize or modify the installation process or Connector/ODBC drivers before installation.
Where to Get Connector/ODBC
MySQL AB distributes all its products under the General Public License (GPL). You can get a copy of the latest version of Connector/ODBC binaries and sources from the MySQL AB Web site http://dev.mysql.com/downloads/.
For more information about Connector/ODBC, visit http://www.mysql.com/products/myodbc/.
For more information about licensing, visit http://www.mysql.com/company/legal/licensing/.
Supported Platforms
Connector/ODBC can be used on all major platforms supported by MySQL. You can install it on:
-
Windows 95, 98, Me, NT, 2000, XP, and 2003
-
All Unix-like Operating Systems, including: AIX, Amiga, BSDI, DEC, FreeBSD, HP-UX 10/11, Linux, NetBSD, OpenBSD, OS/2, SGI Irix, Solaris, SunOS, SCO OpenServer, SCO UnixWare, Tru64 Unix
-
Mac OS X and Mac OS X Server
Using a binary distribution offers the most straightforward method for installing Connector/ODBC. If you want more control over the driver, the installation location and or to customize elements of the driver you will need to build and install from the source.
If a binary distribution is not available for a particular platform build the driver from the original source code. You can contribute the binaries you create to MySQL by sending a mail message to <myodbc@lists.mysql.com>, so that it becomes available for other users.
For further instructions:
29.1.3.1. Installing Connector/ODBC from a Binary Distribution on Windows
Before installing the Connector/ODBC drivers on Windows you should ensure that your Microsoft Data Access Components (MDAC) are up to date. You can obtain the latest version from the Microsoft Data Access and Storage Web site.
There are three available distribution types to use when installing for Windows. The contents in each case are identical, it is only the installation method which is different.
29.1.3.1.1. Installing the Windows Connector/ODBC Driver using an installer
The installer packages offer a very simple method for installing the Connector/ODBC drivers. If you have downloaded the zipped installer then you must extract the installer application. The basic installation process is identical for both installers.
You should follow these steps to complete the installation:
-
Double click on the standalone installer that you extracted, or the MSI file you downloaded.
-
The MySQL Connector/ODBC 3.51 - Setup Wizard will start. Click the Next button to begin the installation process.
-
You will need to choose the installation type. The Typical installation provides the standard files you will need to connect to a MySQL database using ODBC. The Complete option installs all the available files, including debug and utility components. It is recommended you choose one of these two options to complete the installation. If choose one of these methods, click Next and then proceed to step 5.
You may also choose a Custom installation, which enables you to select the individual components that you want to install. You have chosen this method, click Next and then proceed to step 4.
-
If you have chosen a custom installation, use the pop-ups to select which components to install and then click Next to install the necessary files.
-
Once the files have copied to your machine, the installation is complete. Click Finish to exit the installer.
Now the installation is complete, you can continue to configure your ODBC connections using Section 29.1.4, “Connector/ODBC Configuration”.
29.1.3.1.2. Installing the Windows Connector/ODBC Driver using the Zipped DLL package
If you have downloaded the Zipped DLL package then you must install the individual files required for Connector/ODBC operation manually. Once you have unzipped the installation files, you can either perform this operation by hand, executing each statement individually, or you can use the included Batch file to perform an installation to the default locations.
To install using the Batch file:
-
Unzip the Connector/ODBC Zipped DLL package.
-
Open a Command Prompt.
-
Change to the directory created when you unzipped the Connector/ODBC Zipped DLL package.
-
Run Install.bat: C:\> Install.bat
This will copy the necessary files into the default location, and then register the Connector/ODBC driver with the Windows ODBC manager.
If you want to copy the files to an alternative location - for example, to run or test different versions of the Connector/ODBC driver on the same machine, then you must copy the files by hand. It is however not recommended to install these files in a non-standard location. To copy the files by hand to the default installation location use the following steps:
-
Unzip the Connector/ODBC Zipped DLL package.
-
Open a Command Prompt.
-
Change to the directory created when you unzipped the Connector/ODBC Zipped DLL package.
-
Copy the library files to a suitable directory. The default is to copy them into the default Windows system directory \Windows\System32: C:\> copy lib\myodbc3S.dll \Windows\System32
C:\> copy lib\myodbc3S.lib \Windows\System32
C:\> copy lib\myodbc3.dll \Windows\System32
C:\> copy lib\myodbc3.lib \Windows\System32
-
Copy the Connector/ODBC tools. These must be placed into a directory that is in the system PATH. The default is to install these into the Windows system directory \Windows\System32: C:\> copy bin\myodbc3i.exe \Windows\System32
C:\> copy bin\myodbc3m.exe \Windows\System32
C:\> copy bin\myodbc3c.exe \Windows\System32
-
Optionally copy the help files. For these files to be accessible through the help system, they must be installed in the Windows system directory: C:\> copy doc\*.hlp \Windows\System32
-
Finally, you must register the Connector/ODBC driver with the ODBC manager: C:\> myodbc3i -a -d -t"MySQL ODBC 3.51 Driver;\
DRIVER=myodbc3.dll;SETUP=myodbc3S.dll"
You must change the references to the DLL files and command location in the above statement if you have not installed these files into the default location.
29.1.3.2. Installing Connector/ODBC from a Binary Distribution on Unix
There are two methods available for installing Connector/ODBC on Unix from a binary distribution. For most Unix environments you will need to use the tarball distribution. For Linux systems, there is also an RPM distribution available.
29.1.3.2.1. Installing Connector/ODBC from a Binary Tarball Distribution
To install the driver from a tarball distribution (.tar.gz file), download the latest version of the driver for your operating system and follow these steps that demonstrate the process using the Linux version of the tarball: shell> su root
shell> gunzip mysql-connector-odbc-3.51.11-i686-pc-linux.tar.gz
shell> tar xvf mysql-connector-odbc-3.51.11-i686-pc-linux.tar
shell> cd mysql-connector-odbc-3.51.11-i686-pc-linux
Read the installation instructions in the INSTALL-BINARY file and execute these commands. shell> cp libmyodbc* /usr/local/lib
shell> cp odbc.ini /usr/local/etc
shell> export ODBCINI=/usr/local/etc/odbc.ini
Then proceed on to Section 29.1.4.5, “Configuring a Connector/ODBC DSN on Unix”, to configure the DSN for Connector/ODBC. For more information, refer to the INSTALL-BINARY file that comes with your distribution.
29.1.3.2.2. Installing Connector/ODBC from an RPM Distribution
To install or upgrade Connector/ODBC from an RPM distribution on Linux, simply download the RPM distribution of the latest version of Connector/ODBC and follow the instructions below. Use su root to become root, then install the RPM file.
If you are installing for the first time: shell> su root
shell> rpm -ivh mysql-connector-odbc-3.51.12.i386.rpm
If the driver exists, upgrade it like this: shell> su root
shell> rpm -Uvh mysql-connector-odbc-3.51.12.i386.rpm
If there is any dependency error for MySQL client library, libmysqlclient, simply ignore it by supplying the --nodeps option, and then make sure the MySQL client shared library is in the path or set through LD_LIBRARY_PATH.
This installs the driver libraries and related documents to /usr/local/lib and /usr/share/doc/MyODBC, respectively. Proceed onto Section 29.1.4.5, “Configuring a Connector/ODBC DSN on Unix”.
To uninstall the driver, become root and execute an rpm command: shell> su root
shell> rpm -e mysql-connector-odbc
29.1.3.3. Installing Connector/ODBC from a Binary Distribution on Mac OS X
Mac OS X is based on the FreeBSD operating system, and you can normally use the MySQL network port for connecting to MySQL servers on other hosts. Installing the Connector/ODBC driver enables you to connect to MySQL databases on any platform through the ODBC interface. You should only need to install the Connector/ODBC driver when your application requires an ODBC interface. Applications that require or can use ODBC (and therefore the Connector/ODBC driver) include ColdFusion, Filemaker Pro, 4th Dimension and many other applications.
Mac OS X includes its own ODBC manager, based on the iODBC manager. Mac OS X includes an administration tool that provides easier administration of ODBC drivers and configuration, updating the underlying iODBC configuration files.
The method for installing Connector/ODBC on Mac OS X depends on the version on Connector/ODBC you are using. For Connector/ODBC 3.51.14 and later, the package is provided as a compress tar archive that you must manually install. For Connector/ODBC 3.51.13 and earlier the software was provided on a compressed disk image (.dmg) file and included an installer.
In either case, the driver is designed to work with the iODBC driver manager included with Mac OS X.
To install Connector/ODBC 3.51.14 and later:
-
Download the installation file. Note that versions are available for both PowerPC and Intel platforms.
-
Extract the archive: $ tar zxf mysql-connector-odbc-3.51.16-osx10.4-x86-32bit.tar.gz
-
The directory created will contain two subdirectories, lib and bin. You need to copy these to a suitable location such as /usr/local: $ cp bin/* /usr/local/bin
$ cp lib/* /usr/local/lib
-
Finally, you must register the driver with iODBC using the myodbc3i tool you just installed: $ myodbc3i -a -d -t"MySQL ODBC 3.51 Driver;Driver=/usr/local/lib/libmyodbc3.so;Setup=/usr/local/lib/libmyodbc3S.so"
You can verify the installed drivers either by using the ODBC Administrator application or the myodbc3i utility: $ myodbc3i -q -d
To install Connector/ODBC 3.51.13 and earlier, follow these steps:
-
Download the file to your computer and double-click on the downloaded image file.
-
Within the disk image you will find an installer package (with the .pkg extension). Double click on this file to start the Mac OS X installer.
-
You will be presented with the installer welcome message. Click the Continue button to begin the installation process.
-
Please take the time to read the Important Information as it contains guidance on how to complete the installation process. Once you have read the notice and collected the necessary information, click Continue.
-
Connector/ODBC drivers are made available under the GNU General Public License. Please read the license if you are not familiar with it before continuing installation. Click Continue to approve the license (you will be asked to confirm that decision) and continue the installation.
-
Choose a location to install the Connector/ODBC drivers and the ODBC Administrator application. You must install the files onto a drive with an operating system and you may be limited in the choices available. Select the drive you want to use, and then click Continue.
-
The installer will automatically select the files that need to be installed on your machine. Click Install to continue. The installer will copy the necessary files to your machine. A progress bar will be shown indicating the installation progress.
-
When installation has been completed you will get a window like the one shown below. Click Close to close and quit the installer.
29.1.3.4. Installing Connector/ODBC from a Source Distribution on Windows
You should only need to install Connector/ODBC from source on Windows if you want to change or modify the source or installation. If you are unsure whether to install from source, please use the binary installation detailed in Section 29.1.3.1, “Installing Connector/ODBC from a Binary Distribution on Windows”.
Installing Connector/ODBC from source on Windows requires a number of different tools and packages:
-
MDAC, Microsoft Data Access SDK from http://support.microsoft.com/kb/110093.
-
Suitable C compiler, such as Microsoft Visual C++ or the C compiler included with Microsoft Visual Studio.
-
Compatible make tool. Microsoft's nmake is used in the examples in this section.
-
MySQL client libraries and include files from MySQL 4.0.0 or higher. (Preferably MySQL 4.0.16 or higher). This is required because Connector/ODBC uses new calls and structures that exist only starting from this version of the library. To get the client libraries and include files, visit http://dev.mysql.com/downloads/.
29.1.3.4.1. Building Connector/ODBC 3.51
Connector/ODBC source distributions include Makefiles that require the nmake or other make utility. In the distribution, you can find Makefile for building the release version and Makefile_debug for building debugging versions of the driver libraries and DLLs.
To build the driver, use this procedure:
-
Download and extract the sources to a folder, then change directory into that folder. The following command assumes the folder is named myodbc3-src: C:\> cd myodbc3-src
-
Edit Makefile to specify the correct path for the MySQL client libraries and header files. Then use the following commands to build and install the release version: C:\> nmake -f Makefile
C:\> nmake -f Makefile install
nmake -f Makefile builds the release version of the driver and places the binaries in subdirectory called Release.
nmake -f Makefile install installs (copies) the driver DLLs and libraries (myodbc3.dll, myodbc3.lib) to your system directory.
-
To build the debug version, use Makefile_Debug rather than Makefile, as shown below: C:\> nmake -f Makefile_debug
C:\> nmake -f Makefile_debug install
-
You can clean and rebuild the driver by using: C:\> nmake -f Makefile clean
C:\> nmake -f Makefile install
Note
-
Make sure to specify the correct MySQL client libraries and header files path in the Makefiles (set the MYSQL_LIB_PATH and MYSQL_INCLUDE_PATH variables). The default header file path is assumed to be C:\mysql\include. The default library path is assumed to be C:\mysql\lib\opt for release DLLs and C:\mysql\lib\debug for debug versions.
-
For the complete usage of nmake, visit http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vcce4/html/evgrfRunningNMAKE.asp.
-
If you are using the Subversion tree for compiling, all Windows-specific Makefiles are named as Win_Makefile*.
After the driver libraries are copied/installed to the system directory, you can test whether the libraries are properly built by using the samples provided in the samples subdirectory: C:\> cd samples
C:\> nmake -f Makefile all
29.1.3.5. Installing Connector/ODBC from a Source Distribution on Unix
You need the following tools to build MySQL from source on Unix:
-
A working ANSI C++ compiler. gcc 2.95.2 or later, SGI C++, and SunPro C++ are some of the compilers that are known to work.
-
A good make program. GNU make is always recommended and is sometimes required.
-
MySQL client libraries and include files from MySQL 4.0.0 or higher. (Preferably MySQL 4.0.16 or higher). This is required because Connector/ODBC uses new calls and structures that exist only starting from this version of the library. To get the client libraries and include files, visit http://dev.mysql.com/downloads/.
If you have built your own MySQL server and/or client libraries from source then you must have used the --enable-thread-safe-client option to configure when the libraries were built.
You should also ensure that the libmysqlclient library were built and installed as a shared library.
-
A compatible ODBC manager must be installed. Connector/ODBC is known to work with the iODBC and unixODBC managers. See Section 29.1.2.2.2, “ODBC Driver Managers”, for more information.
-
If you are using a character set that isn't compiled into the MySQL client library then you need to install the MySQL character definitions from the charsets directory into SHAREDIR (by default, /usr/local/mysql/share/mysql/charsets). These should be in place if you have installed the MySQL server on the same machine. See Section 9.1, “Character Set Support”, for more information on character set support.
Once you have all the required files, unpack the source files to a separate directory, you then have to run configure and build the library using make.
29.1.3.5.1. Typical configure Options
The configure script gives you a great deal of control over how you configure your Connector/ODBC build. Typically you do this using options on the configure command line. You can also affect configure using certain environment variables. For a list of options and environment variables supported by configure, run this command: shell> ./configure --help
Some of the more commonly used configure options are described here:
-
To compile Connector/ODBC, you need to supply the MySQL client include and library files path using the --with-mysql-path=DIR option, where DIR is the directory where MySQL is installed.
MySQL compile options can be determined by running DIR/bin/mysql_config.
-
Supply the standard header and library files path for your ODBC Driver Manager (iODBC or unixODBC).
-
If you are using iODBC and iODBC is not installed in its default location (/usr/local), you might have to use the --with-iodbc=DIR option, where DIR is the directory where iODBC is installed.
If the iODBC headers do not reside in DIR/include, you can use the --with-iodbc-includes=INCDIR option to specify their location.
The applies to libraries. If they are not in DIR/lib, you can use the --with-iodbc-libs=LIBDIR option.
-
If you are using unixODBC, use the --with-unixODBC=DIR option (case sensitive) to make configure look for unixODBC instead of iODBC by default, DIR is the directory where unixODBC is installed.
If the unixODBC headers and libraries aren't located in DIR/include and DIR/lib, use the --with-unixODBC-includes=INCDIR and --with-unixODBC-libs=LIBDIR options.
-
You might want to specify an installation prefix other than /usr/local. For example, to install the Connector/ODBC drivers in /usr/local/odbc/lib, use the --prefix=/usr/local/odbc option.
The final configuration command looks something like this: shell> ./configure --prefix=/usr/local \
--with-iodbc=/usr/local \
--with-mysql-path=/usr/local/mysql
29.1.3.5.2. Additional configure Options
There are a number of other options that you need, or want, to set when configuring the Connector/ODBC driver before it is built.
-
To link the driver with MySQL thread safe client libraries libmysqlclient_r.so or libmysqlclient_r.a, you must specify the following configure option: --enable-thread-safe
and can be disabled (default) using --disable-thread-safe
This option enables the building of the driver thread-safe library libmyodbc3_r.so from by linking with MySQL thread-safe client library libmysqlclient_r.so (The extensions are OS dependent).
If the compilation with the thread-safe option fails, it may be because the correct thread-libraries on the system could not be located. You should set the value of LIBS to point to the correct thread library for your system. LIBS="-lpthread" ./configure ..
-
You can enable or disable the shared and static versions of Connector/ODBC using these options: --enable-shared[=yes/no]
--disable-shared
--enable-static[=yes/no]
--disable-static
-
By default, all the binary distributions are built as non-debugging versions (configured with --without-debug).
To enable debugging information, build the driver from source distribution and use the --with-debug option when you run configure.
-
This option is available only for source trees that have been obtained from the Subversion repository. This option does not apply to the packaged source distributions.
By default, the driver is built with the --without-docs option. If you would like the documentation to be built, then execute configure with: --with-docs
29.1.3.5.3. Building and Compilation
To build the driver libraries, you have to just execute make. shell> make
If any errors occur, correct them and continue the build process. If you aren't able to build, then send a detailed email to <myodbc@lists.mysql.com> for further assistance.
29.1.3.5.4. Building Shared Libraries
On most platforms, MySQL does not build or support .so (shared) client libraries by default. This is based on our experience of problems when building shared libraries.
In cases like this, you have to download the MySQL distribution and configure it with these options: --without-server --enable-shared
To build shared driver libraries, you must specify the --enable-shared option for configure. By default, configure does not enable this option.
If you have configured with the --disable-shared option, you can build the .so file from the static libraries using the following commands: shell> cd mysql-connector-odbc-3.51.01
shell> make
shell> cd driver
shell> CC=/usr/bin/gcc \
$CC -bundle -flat_namespace -undefined error \
-o .libs/libmyodbc3-3.51.01.so \
catalog.o connect.o cursor.o dll.o error.o execute.o \
handle.o info.o misc.o myodbc3.o options.o prepare.o \
results.o transact.o utility.o \
-L/usr/local/mysql/lib/mysql/ \
-L/usr/local/iodbc/lib/ \
-lz -lc -lmysqlclient -liodbcinst
Make sure to change -liodbcinst to -lodbcinst if you are using unixODBC instead of iODBC, and configure the library paths accordingly.
This builds and places the libmyodbc3-3.51.01.so file in the .libs directory. Copy this file to the Connector/ODBC library installation directory (/usr/local/lib (or the lib directory under the installation directory that you supplied with the --prefix). shell> cd .libs
shell> cp libmyodbc3-3.51.01.so /usr/local/lib
shell> cd /usr/local/lib
shell> ln -s libmyodbc3-3.51.01.so libmyodbc3.so
To build the thread-safe driver library: shell> CC=/usr/bin/gcc \
$CC -bundle -flat_namespace -undefined error
-o .libs/libmyodbc3_r-3.51.01.so
catalog.o connect.o cursor.o dll.o error.o execute.o
handle.o info.o misc.o myodbc3.o options.o prepare.o
results.o transact.o utility.o
-L/usr/local/mysql/lib/mysql/
-L/usr/local/iodbc/lib/
-lz -lc -lmysqlclient_r -liodbcinst
29.1.3.5.5. Installing Driver Libraries
To install the driver libraries, execute the following command: shell> make install
That command installs one of the following sets of libraries:
For Connector/ODBC 3.51:
For thread-safe Connector/ODBC 3.51:
-
libmyodbc3_r.so
-
libmyodbc3-3_r.51.01.so
-
libmyodbc3_r.a
For more information on build process, refer to the INSTALL file that comes with the source distribution. Note that if you are trying to use the make from Sun, you may end up with errors. On the other hand, GNU gmake should work fine on all platforms.
29.1.3.5.6. Testing Connector/ODBC on Unix
To run the basic samples provided in the distribution with the libraries that you built, use the following command: shell> make test
Before running the tests, create the DSN 'myodbc3' in odbc.ini and set the environment variable ODBCINI to the correct odbc.ini file; and MySQL server is running. You can find a sample odbc.ini with the driver distribution.
You can even modify the samples/run-samples script to pass the desired DSN, UID, and PASSWORD values as the command-line arguments to each sample.
29.1.3.5.7. Building Connector/ODBC from Source on Mac OS X
To build the driver on Mac OS X (Darwin), make use of the following configure example: shell> ./configure --prefix=/usr/local
--with-unixODBC=/usr/local
--with-mysql-path=/usr/local/mysql
--disable-shared
--enable-gui=no
--host=powerpc-apple
The command assumes that the unixODBC and MySQL are installed in the default locations. If not, configure accordingly.
On Mac OS X, --enable-shared builds .dylib files by default. You can build .so files like this: shell> make
shell> cd driver
shell> CC=/usr/bin/gcc \
$CC -bundle -flat_namespace -undefined error
-o .libs/libmyodbc3-3.51.01.so *.o
-L/usr/local/mysql/lib/
-L/usr/local/iodbc/lib
-liodbcinst -lmysqlclient -lz -lc
To build the thread-safe driver library: shell> CC=/usr/bin/gcc \
$CC -bundle -flat_namespace -undefined error
-o .libs/libmyodbc3-3.51.01.so *.o
-L/usr/local/mysql/lib/
-L/usr/local/iodbc/lib
-liodbcinst -lmysqlclienti_r -lz -lc -lpthread
Make sure to change the -liodbcinst to -lodbcinst in case of using unixODBC instead of iODBC and configure the libraries path accordingly.
In Apple's version of GCC, both cc and gcc are actually symbolic links to gcc3.
Copy this library to the $prefix/lib directory and symlink to libmyodbc3.so.
You can cross-check the output shared-library properties using this command: shell> otool -LD .libs/libmyodbc3-3.51.01.so
29.1.3.5.8. Building Connector/ODBC from Source on HP-UX
To build the driver on HP-UX 10.x or 11.x, make use of the following configure example:
If using cc: shell> CC="cc" \
CFLAGS="+z" \
LDFLAGS="-Wl,+b:-Wl,+s" \
./configure --prefix=/usr/local
--with-unixodbc=/usr/local
--with-mysql-path=/usr/local/mysql/lib/mysql
--enable-shared
--enable-thread-safe
If using gcc: shell> CC="gcc" \
LDFLAGS="-Wl,+b:-Wl,+s" \
./configure --prefix=/usr/local
--with-unixodbc=/usr/local
--with-mysql-path=/usr/local/mysql
--enable-shared
--enable-thread-safe
Once the driver is built, cross-check its attributes using chatr .libs/libmyodbc3.sl to determine whether you need to have set the MySQL client library path using the SHLIB_PATH environment variable. For static versions, ignore all shared-library options and run configure with the --disable-shared option.
29.1.3.5.9. Building Connector/ODBC from Source on AIX
To build the driver on AIX, make use of the following configure example: shell> ./configure --prefix=/usr/local
--with-unixodbc=/usr/local
--with-mysql-path=/usr/local/mysql
--disable-shared
--enable-thread-safe
29.1.3.6. Installing Connector/ODBC from the Development Source Tree
Caution
You should read this section only if you are interested in helping us test our new code. If you just want to get MySQL Connector/ODBC up and running on your system, you should use a standard release distribution.
To be able to access the Connector/ODBC source tree, you must have Subversion installed. Subversion is freely available from http://subversion.tigris.org/.
To build from the source trees, you need the following tools:
-
autoconf 2.52 (or newer)
-
automake 1.4 (or newer)
-
libtool 1.4 (or newer)
-
m4
The most recent development source tree is available from our public Subversion trees at http://dev.mysql.com/tech-resources/sources.html.
To checkout out the Connector/ODBC sources, change to the directory where you want the copy of the Connector/ODBC tree to be stored, then use the following command: shell> svn co http://svn.mysql.com/svnpublic/connector-odbc3
You should now have a copy of the entire Connector/ODBC source tree in the directory connector-odbc3. To build from this source tree on Unix or Linux follow these steps: shell> cd connector-odbc3
shell> aclocal
shell> autoheader
shell> autoconf
shell> automake;
shell> ./configure # Add your favorite options here
shell> make
For more information on how to build, refer to the INSTALL file located in the same directory. For more information on options to configure, see Section 29.1.3.5.1, “Typical configure Options”
When the build is done, run make install to install the Connector/ODBC 3.51 driver on your system.
If you have gotten to the make stage and the distribution does not compile, please report it to <myodbc@lists.mysql.com>.
On Windows, make use of Windows Makefiles WIN-Makefile and WIN-Makefile_debug in building the driver. For more information, see Section 29.1.3.4, “Installing Connector/ODBC from a Source Distribution on Windows”.
After the initial checkout operation to get the source tree, you should run svn update periodically update your source according to the latest version.
29.1.4. Connector/ODBC Configuration
Before you connect to a MySQL database using the Connector/ODBC driver you must configure an ODBC Data Source Name. The DSN associates the various configuration parameters required to communicate with a database to a specific name. You use the DSN in an application to communicate with the database, rather than specifying individual parameters within the application itself. DSN information can be user specific, system specific, or provided in a special file. ODBC data source names are configured in different ways, depending on your platform and ODBC driver.
29.1.4.1. Data Source Names
A Data Source Name associates the configuration parameters for communicating with a specific database. Generally a DSN consists of the following parameters:
- Name
- Hostname
- Database Name
- Login
- Password
In addition, different ODBC drivers, including Connector/ODBC, may accept additional driver-specific options and parameters.
There are three types of DSN:
-
A System DSN is a global DSN definition that is available to any user and application on a particular system. A System DSN can normally only be configured by a systems administrator, or by a user who has specific permissions that let them create System DSNs.
-
A User DSN is specific to an individual user, and can be used to store database connectivity information that the user regularly uses.
-
A File DSN uses a simple file to define the DSN configuration. File DSNs can be shared between users and machines and are therefore more practical when installing or deploying DSN information as part of an application across many machines.
DSN information is stored in different locations depending on your platform and environment.
29.1.4.2. Connector/ODBC Connection Parameters
You can specify the parameters in the following tables for Connector/ODBC when configuring a DSN. Users on Windows can use the Options and Advanced panels when configuring a DSN to set these parameters; see the table for information on which options relate to which fields and checkboxes. On Unix and Mac OS X, use the parameter name and value as the keyword/value pair in the DSN configuration. Alternatively, you can set these parameters within the InConnectionString argument in the SQLDriverConnect() call.
Note
The SSL configuration parameters can also be automatically loaded from a my.ini or my.cnf file.
The option argument is used to tell Connector/ODBC that the client isn't 100% ODBC compliant. On Windows, you normally select options by toggling the checkboxes in the connection screen, but you can also select them in the option argument. The following options are listed in the order in which they appear in the Connector/ODBC connect screen:
To select multiple options, add together their values. For example, setting option to 12 (4+8) gives you debugging without packet limits.
The following table shows some recommended option values for various configurations:
29.1.4.3. Configuring a Connector/ODBC DSN on Windows
The ODBC Data Source Administrator within Windows enables you to create DSNs, check driver installation and configure ODBC systems such as tracing (used for debugging) and connection pooling.
Different editions and versions of Windows store the ODBC Data Source Administrator in different locations depending on the version of Windows that you are using.
To open the ODBC Data Source Administrator in Windows Server 2003:
Tip
Because it is possible to create DSN using either the 32-bit or 64-bit driver, but using the same DNS identifier, it is advisable to include the driver being used within the DSN identifier. This will help you to identify the DSN when using it from applications such as Excel that are only compatible with the 32-bit driver. For example, you might add Using32bitCODBC to the DSN identifier for the 32-bit interface and Using64bitCODBC for those using the 64-bit Connector/ODBC driver.
-
On the Start menu, choose Administrative Tools, and then click Data Sources (ODBC).
To open the ODBC Data Source Administrator in Windows 2000 Server or Windows 2000 Professional:
-
On the Start menu, choose Settings, and then click Control Panel.
-
In Control Panel, click Administrative Tools.
-
In Administrative Tools, click Data Sources (ODBC).
To open the ODBC Data Source Administrator on Windows XP:

-
Right click on the Start menu.
-
Select Properties.
-
Click Customize....
-
Select the Advanced tab.
-
Within Start menu items, within the System Administrative Tools section, select Display on the All Programs menu.
Within both Windows Server 2003 and Windows XP you may want to permanently add the ODBC Data Source Administrator to your Start menu. To do this, locate the Data Sources (ODBC) icon using the methods shown, then right-click on the icon and then choose Pin to Start Menu.
The interfaces for the 3.51 and 5.1 versions of the Connector/ODBC driver are different, although the fields and information that you need to enter remain the same.
To configure a DSN using Connector/ODBC 3.51.x or Connector/ODBC 5.1.0, see Section 29.1.4.3.1, “Configuring a Connector/ODBC 3.51 DSN on Windows”.
To configure a DSN using Connector/ODBC 5.1.1 or later, see Section 29.1.4.3.2, “Configuring a Connector/ODBC 5.1 DSN on Windows”.
29.1.4.3.1. Configuring a Connector/ODBC 3.51 DSN on Windows
To add and configure a new Connector/ODBC data source on Windows, use the ODBC Data Source Administrator:
-
Open the ODBC Data Source Administrator.
-
To create a System DSN (which will be available to all users) , select the System DSN tab. To create a User DSN, which will be unique only to the current user, click the Add... button.
-
You will need to select the ODBC driver for this DSN.
Select MySQL ODBC 3.51 Driver, then click Finish.
-
You now need to configure the specific fields for the DSN you are creating through the Add Data Source Name dialog.
In the Data Source Name box, enter the name of the data source you want to access. It can be any valid name that you choose.
-
In the Description box, enter some text to help identify the connection.
-
In the Server field, enter the name of the MySQL server host that you want to access. By default, it is localhost.
-
In the User field, enter the user name to use for this connection.
-
In the Password field, enter the corresponding password for this connection.
-
The Database pop-up should automatically populate with the list of databases that the user has permissions to access.
-
Click OK to save the DSN.
A completed DSN configuration may look like this:
You can verify the connection using the parameters you have entered by clicking the Test button. If the connection could be made successfully, you will be notified with a Success; connection was made! dialog.
If the connection failed, you can obtain more information on the test and why it may have failed by clicking the Diagnostics... button to show additional error messages.
You can configure a number of options for a specific DSN by using either the Connect Options or Advanced tabs in the DSN configuration dialog.
The three options you can configure are:
-
Port sets the TCP/IP port number to use when communicating with MySQL. Communication with MySQL uses port 3306 by default. If your server is configured to use a different TCP/IP port, you must specify that port number here.
-
Socket sets the name or location of a specific socket or Windows pipe to use when communicating with MySQL.
-
Initial Statement defines an SQL statement that will be executed when the connection to MySQL is opened. You can use this to set MySQL options for your connection, such as disabling autocommit.
-
Character Set is a pop-up list from which you can select the default character set to be used with this connection. The Character Set option was added in 3.5.17.
The Advanced tab enables you to configure Connector/ODBC connection parameters. Refer to Section 29.1.4.2, “Connector/ODBC Connection Parameters”, for information about the meaning of these options.
29.1.4.3.2. Configuring a Connector/ODBC 5.1 DSN on Windows
The DSN configuration when using Connector/ODBC 5.1.1 and later has a slightly different layout. Also, due to the native Unicode support within Connector/ODBC 5.1, you no longer need to specify the initial character set to be used with your connection.
To configure a DSN using the Connector/ODBC 5.1.1 or later driver:
-
Open the ODBC Data Source Administrator.
-
To create a System DSN (which will be available to all users) , select the System DSN tab. To create a User DSN, which will be unique only to the current user, click the Add... button.
-
You will need to select the ODBC driver for this DSN.
Select MySQL ODBC 5.1 Driver, then click Finish.
-
You now need to configure the specific fields for the DSN you are creating through the Connection Parameters dialog.
In the Data Source Name box, enter the name of the data source you want to access. It can be any valid name that you choose.
-
In the Description box, enter some text to help identify the connection.
-
In the Server field, enter the name of the MySQL server host that you want to access. By default, it is localhost.
-
In the User field, enter the user name to use for this connection.
-
In the Password field, enter the corresponding password for this connection.
-
The Database pop-up should automatically populate with the list of databases that the user has permissions to access.
-
To communicate over a different TCP/IP port than the default (3306), change the value of the Port.
-
Click OK to save the DSN.
You can verify the connection using the parameters you have entered by clicking the Test button. If the connection could be made successfully, you will be notified with a Success; connection was made! dialog.
You can configure a number of options for a specific DSN by using the Details button.
The Details button opens a tabbed display which allows you to set additional options:
-
Flags 1, Flags 2, and Flags 3 enable you to select the additional flags for the DSN connection. For more information on these flags, see Section 29.1.4.2, “Connector/ODBC Connection Parameters”.
-
Debug allows you to enable ODBC debugging to record the queries you execute through the DSN to the myodbc.sql file. For more information, see Section 29.1.4.8, “Getting an ODBC Trace File”.
-
SSL Settings configures the additional options required for using the Secure Sockets Layer (SSL) when communicating with MySQL server. Note that you must have enabled SSL and configured the MySQL server with suitable certificates to communicate over SSL.
The Advanced tab enables you to configure Connector/ODBC connection parameters. Refer to Section 29.1.4.2, “Connector/ODBC Connection Parameters”, for information about the meaning of these options.
29.1.4.3.3. Errors and Debugging
This section answers Connector/ODBC connection-related questions.
-
While configuring a Connector/ODBC DSN, a Could Not Load Translator or Setup Library error occurs
For more information, refer to MS KnowledgeBase Article(Q260558). Also, make sure you have the latest valid ctl3d32.dll in your system directory.
-
On Windows, the default myodbc3.dll is compiled for optimal performance. If you want to debug Connector/ODBC 3.51 (for example, to enable tracing), you should instead use myodbc3d.dll. To install this file, copy myodbc3d.dll over the installed myodbc3.dll file. Make sure to revert back to the release version of the driver DLL once you are done with the debugging because the debug version may cause performance issues. Note that the myodbc3d.dll isn't included in Connector/ODBC 3.51.07 through 3.51.11. If you are using one of these versions, you should copy that DLL from a previous version (for example, 3.51.06).
29.1.4.4. Configuring a Connector/ODBC DSN on Mac OS X
To configure a DSN on Mac OS X you can either use the myodbc3i utility, edit the odbc.ini file within the Library/ODBC directory of the user or the should use the ODBC Administrator. If you have Mac OS X 10.2 or earlier, refer to Section 29.1.4.5, “Configuring a Connector/ODBC DSN on Unix”. Select whether you want to create a User DSN or a System DSN. If you want to add a System DSN, you may need to authenticate with the system. You must click the padlock and enter a user and password with administrator privileges.
For correct operation of ODBC Administrator, you should ensure that the /Library/ODBC/odbc.ini file used to set up ODBC connectivity and DSNs are writable by the admin group. If this file is not writable by this group then the ODBC Administrator may fail, or may appear to have worked but not generated the correct entry.
Warning
There are known issues with the OS X ODBC Administrator and Connector/ODBC that may prevent you from creating a DSN using this method. In this case you should use the command-line or edit the odbc.ini file directly. Note that existing DSNs or those that you create via the myodbc3i or myodbc-installertool can still be checked and edited using ODBC Administrator.
To create a DSN using the myodbc3i utility, you need only specify the DSN type and the DSN connection string. For example: $ myodbc3i -a -s -t"DSN=mydb;DRIVER=MySQL ODBC 3.51 Driver;SERVER=mysql;USER=username;PASSWORD=pass"
To use ODBC Administrator:
-
Open the ODBC Administrator from the Utilities folder in the Applications folder.
-
On the User DSN or System DSN panel, click Add.
-
Select the Connector/ODBC driver and click OK.
-
You will be presented with the Data Source Name dialog. Enter The Data Source Name and an optional Description for the DSN.
-
Click Add to add a new keyword/value pair to the panel. You should configure at least four pairs to specify the server, username, password and database connection parameters. See Section 29.1.4.2, “Connector/ODBC Connection Parameters”.
-
Click OK to add the DSN to the list of configured data source names.
A completed DSN configuration may look like this:
You can configure additional ODBC options to your DSN by adding further keyword/value pairs and setting the corresponding values. See Section 29.1.4.2, “Connector/ODBC Connection Parameters”.
29.1.4.5. Configuring a Connector/ODBC DSN on Unix
On Unix, you configure DSN entries directly in the odbc.ini file. Here is a typical odbc.ini file that configures myodbc3 as the DSN name for Connector/ODBC 3.51: ;
; odbc.ini configuration for Connector/ODBC and Connector/ODBC 3.51 drivers
;
[ODBC Data Sources]
myodbc3 = MyODBC 3.51 Driver DSN
[myodbc3]
Driver = /usr/local/lib/libmyodbc3.so
Description = Connector/ODBC 3.51 Driver DSN
SERVER = localhost
PORT =
USER = root
Password =
Database = test
OPTION = 3
SOCKET =
[Default]
Driver = /usr/local/lib/libmyodbc3.so
Description = Connector/ODBC 3.51 Driver DSN
SERVER = localhost
PORT =
USER = root
Password =
Database = test
OPTION = 3
SOCKET =
Refer to the Section 29.1.4.2, “Connector/ODBC Connection Parameters”, for the list of connection parameters that can be supplied.
Note
If you are using unixODBC, you can use the following tools to set up the DSN:
In some cases when using unixODBC, you might get this error: Data source name not found and no default driver specified
If this happens, make sure the ODBCINI and ODBCSYSINI environment variables are pointing to the right odbc.ini file. For example, if your odbc.ini file is located in /usr/local/etc, set the environment variables like this: export ODBCINI=/usr/local/etc/odbc.ini
export ODBCSYSINI=/usr/local/etc
29.1.4.6. Connecting Without a Predefined DSN
You can connect to the MySQL server using SQLDriverConnect, by specifying the DRIVER name field. Here are the connection strings for Connector/ODBC using DSN-Less connections:
For Connector/ODBC 3.51: ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};\
SERVER=localhost;\
DATABASE=test;\
USER=venu;\
PASSWORD=venu;\
OPTION=3;"
If your programming language converts backslash followed by whitespace to a space, it is preferable to specify the connection string as a single long string, or to use a concatenation of multiple strings that does not add spaces in between. For example: ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};"
"SERVER=localhost;"
"DATABASE=test;"
"USER=venu;"
"PASSWORD=venu;"
"OPTION=3;"
Note. Note that on Mac OS X you may need to specify the full path to the Connector/ODBC driver library.
Refer to the |
