ExtendedOps

Applies to:

Description

Extended operation calls return a set of records which matches the selected fields and selected records on a single call. These operations are significantly faster than a number of single record operations which would accomplish the same thing.

If this property is True, the VAccess control can retrieve records using the extended fetch methods.

When the ExtendedOps property is False, or when the AutoMode property is set to True, methods that use extended operations, such as GetNextExtended, GetPreviousExtended, StepNextExtended, and StepPreviousExtended, will all return a status code of -1 indicating that extended operations are unavailable.

Remarks

If this property is False (default), the VAccess control will navigate the Pervasive PSQL data file and retrieve records using single record fetch operations.
