Easysoft ODBC-ISAM DriverDoes Easysoft Data Access for ISAM use the indexes set on my ISAM files? |
|
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.
