The
QUERY-OFF-END attribute corresponds to the QUERY-OFF-END function.
Note: ABL also provides an OFF-END
event for when a query on a ProDataSet temp-table buffer is positioned
past the last row. You can use this event to retrieve additional
data source rows to add at the bottom of a ProDataSet temp-table
(for example, in batches when there are too many data source rows
to retrieve at one time). The OFF-END event is similar to the QUERY-OFF-END attribute,
which is set to TRUE whenever the associated query object is positioned past
the last row. The difference is that you must test the QUERY-OFF-END
attribute for this condition at a specific place in your application
code, whereas the OFF-END event procedure executes like a trigger
whenever the event occurs. For more information about the OFF-END
event on a ProDataSet temp-table query, see the
ProDataSet events.
