The name of the ODBC driver (DBODBC16.DLL) changed in SAP Sybase IQ 16.0.
In 15.4, the driver name was SQL Anywhere. In 16.0, the driver name is Sybase IQ.
If you have an ODBC application that references the driver name directly, you will need to update the driver name in the application. If your ODBC application references the data source name, no application changes are required.
