The ODBC Driver is installed with the driver names “Ingres” and “Ingres xx", where xx is the value of II_INSTALLATION. Thus, regardless of the Actian X version or location, the driver name “Ingres” always references the most recent installation of the ODBC Driver, and "Ingres xx" is the name of the driver associated with an Actian X installation with an instance ID of "xx". Read-only drivers are named "Ingres Read Only" and "Ingres xx Read Only."

If multiple versions of Actian X are installed on the same machine, we recommend to always reference the "Ingres xx" driver in connection strings or when creating an ODBC data source name; otherwise, subsequent installations or upgrades may corrupt the driver path defined by the driver name "Ingres". If the machine has only one Actian X installation, "Ingres" or "Ingres xx" can be used.
