If the IncludeCurrent property of the control is
True, the extended fetch operation will begin with the current record. If this property is
False, the extended fetch operation will begin with the next record in the record sequence.
If the operation is successful, the resulting record set values will be available through the Row and
Column properties. The number of Rows and Columns returned by the operation are available in the
Rows and
Columns properties, and the PSQL status is returned by the method and is available in the
Status property.
Before invoking this method, you must first configure the control for extended fetch operations by setting the desired record selection and field selection criteria in the SelectedRecords and
SelectedFields properties, and then invoking the
Init method to allocate the necessary request buffer structures. You can also first establish current record positioning in the file using a single record fetch method such as
StepLast.
This method has no effect if the ExtendedOps property of the control is
False or
AutoMode is set to
True.
