The Easysoft ODBC-MySQL Driver is installed on the computer where your applications are running. ODBC applications access ODBC drivers through the ODBC Driver Manager and a data source. The data source tells the Driver Manager which ODBC driver to load, which MySQL server to connect to and how to connect to it. This chapter describes how to create data sources, use DSN-less connections and configure the Easysoft ODBC-MySQL Driver.
Before setting up a data source, you must have successfully installed the Easysoft ODBC-MySQL Driver.
For Easysoft ODBC-MySQL Driver installation instructions, see Installation.
This section describes how to configure the Easysoft ODBC-MySQL Driver to connect to a MySQL database by using a data source or a DSN-less connection string. The section assumes you are, or are able to consult with, a database administrator.
Refer to the section relevant to your platform to continue:
There are two ways to set up a data source to your MySQL data:
By default, the Easysoft ODBC-MySQL Driver installation creates a SYSTEM data source named [MYSQL_SAMPLE]. If you are using the unixODBC included in the Easysoft ODBC-MySQL Driver distribution, the SYSTEM odbc.ini file is in /etc.
If you built unixODBC yourself, or installed it from some other source, SYSTEM data sources are stored in the path specified with the configure option --sysconfdir=directory. If sysconfdir was not specified when unixODBC was configured and built, it defaults to /usr/local/etc.
If you accepted the default choices when installing the Easysoft ODBC-MySQL Driver, USER data sources must be created and edited in $HOME/.odbc.ini.
|
To display the directory where unixODBC stores SYSTEM and USER data sources, type odbcinst -j. By default, you must be logged in as root to edit a SYSTEM data source defined in /etc/odbc.ini. |
You can either edit the sample data source or create new data sources.
Each section of the odbc.ini file starts with a data source name in square brackets [ ] followed by a number of attribute=value pairs.
|
Attribute names in odbc.ini are not case sensitive. |
The Driver attribute identifies the ODBC driver in the odbcinst.ini file to use for a data source.
When the Easysoft ODBC-MySQL Driver is installed into unixODBC, it places an Easysoft ODBC-MySQL entry in odbcinst.ini. For Easysoft ODBC-MySQL Driver data sources therefore, you need to include a Driver = Easysoft ODBC-MySQL entry.
To configure a MySQL data source, in your odbc.ini file, you need to specify:
The Easysoft ODBC-MySQL Driver must be able to find the following shared objects, which are installed during the Easysoft ODBC-MySQL Driver installation:
By default, this is located in /usr/local/easysoft/unixODBC/lib.
By default, this is located in /usr/local/easysoft/lib.
By default, this is located in /usr/local/easysoft/lib.
You may need to set and export LD_LIBRARY_PATH, SHLIB_PATH or LIBPATH (depending on your operating system and run-time linker) to include the directories where libodbcinst.so, libeslicshr.so and libessupp.so are located.
|
The shared object file extension (.so) may vary depending on the operating system (.so, .a or .sl). |
The isql query tool lets you test your Easysoft ODBC-MySQL Driver data sources.
To test the Easysoft ODBC-MySQL Driver connection
1. Change directory into /usr/local/easysoft/unixODBC/bin.
2. Type ./isql.sh -v data_source, where data_source is the name of the target data source.
3. At the prompt, type an SQL query. For example:
Type help to return a list of tables:
To connect an ODBC application on a Windows machine to a Salesforce database:

2. Select the User DSN tab to set up a data source that only you can access.
Select the System DSN tab to create a data source which is available to anyone who logs on to this Windows machine.
3. Click Add... to add a new data source.
The Create New Data Source dialog box displays a list of drivers:
4. Select Easysoft ODBC-MySQL Driver and click Finish.
The Easysoft ODBC-MySQL Driver DSN Setup dialog box is displayed:
For details of the attributes that can be set on this dialog box, see Attribute Fields.

The Easysoft installer program installs both a 32-bit and a 64-bit version of the Easysoft ODBC-MySQL Driver. If you want to use a 64-bit ODBC application, you need to use the 64-bit Easysoft ODBC-MySQL Driver. If you want to use a 32-bit ODBC application, you need to use the 32-bit Easysoft ODBC-MySQL Driver. There is both a 32-bit and a 64-bit version of ODBC Administrator. The 64-bit ODBC Administrator is located in Control Panel under Administrative tools. To access the 32-bit ODBC Administrator in Windows 7 and earlier, in the Windows Run dialog box, type: %windir%\syswow64\odbcad32.exe On Windows 8, both the 32-bit and 64-bit ODBC Administrator are located in Control Panel under Administrative tools: ODBC Data Sources (32-bit) and ODBC Data Sources (64-bit). Easysoft ODBC-MySQL Driver data sources created in the 64-bit ODBC Administrator will specify the 64-bit version of the Easysoft ODBC-MySQL Driver. Easysoft ODBC-MySQL Driver data sources created in the 32-bit ODBC Administrator will specify the 32-bit version of the Easysoft ODBC-MySQL Driver. If you want to create an Easysoft ODBC-MySQL Driver System data source for use with a 64-bit application, use the 64-bit ODBC Administrator. If you want to create an Easysoft ODBC-MySQL Driver System data source for use with a 32-bit application, use the 32-bit ODBC Administrator. For Easysoft ODBC-MySQL Driver User data sources, it does not matter which version of the ODBC Administrator that you use. |

In addition to using a data source, you can also connect to a database by using a DSN-less connection string of the form:
SQLDriverConnect(..."DRIVER={Easysoft ODBC-MySQL};
Server=server;UID=user;PWD=password;
where server is the host name or IP address of the machine on which the MySQL instance is running, user and password are a valid operating system user name and password and database isthe MySQL database you want to connect to. You need to use the Easysoft ODBC-MySQL DRIVER keyword to identify the Easysoft ODBC-MySQL Driver.
Other Easysoft ODBC-MySQL Driver attribute settings, as described in Setting Up Data Sources on Unix, can be added to the connection string using the same PARAMETER=value; format. For example, the following connection string connects to a MySQL server that is listening on a non-standard port.
"DRIVER={Easysoft ODBC-MySQL};Server=myhost;UID=myuser;PWD=mypassword;Database=Employees;Port=50001"
"DRIVER={Easysoft MySQL ODBC Driver};Server=myhost;UID=myuser;PWD=mypassword;Database=Employees;Port=50001"
