Each release of Actian X includes an ODBC driver. Each ODBC driver is designed to be compatible with the major and minor release numbers of that product. Thus, the ODBC driver released with Ingres 9.1.1 is designed to be compatible with Ingres 9.1.0, since the major and minor release numbers are 9 and 1, respectively. Compatibility beyond that scope is not supported. Thus, an ODBC driver released with Ingres 10.0 is not compatible with an Ingres 9.2 environment, or vice versa.

For Ingres 9.0 (also known as Ingres 2006) and higher, the Ingres ODBC Driver 3.5 is required. For previous releases, either ODBC 3.5 or ODBC 2.8 is supported. Prior to Ingres 9.0, there is no ODBC CLI on Linux; the unixODBC Driver Manager is required.
