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 Section 17.1.4.2, “Connector/ODBC Connection Parameters”, for the list of connection parameters that can be supplied.
