Easysoft ODBC-Zortec System Z DriverDoes Easysoft Data Access for Zortec SystemZ use the indexes set on my Zortec data? |

Yes, the Easysoft ODBC-SQI SQL Engine uses index calls passed through to the files by the SQI-ISAM Driver as part of its query formulation. From these the Engine will score the indexes and work out which should be used to run the SQL query most efficiently.
