This variable lets you specify a particular ODBC SQL Server driver name for the SQL Server interface. SQL Server is the value set by default, and is the most commonly found name; however, if you intend to use a different driver, set the value to the name of the intended driver, as shown in the ODBC Data Source dialog box (Windows) or odbcinst.ini (UNIX/Linux). Results are undefined if changed to a value which is not a valid supported SQL Server ODBC driver on your system.

The following is a list of currently supported drivers:
  • SQL Server
  • SQL Server Native Client 10.0
  • SQL Server Native Client 11.0
  • ODBC Driver 11 for SQL Server
  • ODBC Driver 12 for SQL Server
  • ODBC Driver 13 for SQL Server
  • ODBC Driver 13.1 for SQL Server
  • ODBC Driver 17 for SQL Server (UNIX/Linux only)
