>What determines the speed of a parameter view? I have a form with a pview based grid. The pview is a simple:
>select * from DETAIL where ID = ?pID

>In the Form.MoveRec() method there is something like:
>pID = MASTER.ID
>requery(grid.Recordsource)
>gird.refresh()
>
>MASTER has some 3,000 records and DETAIL 100,000

>It takes 25 seconds to requery the grid!

>If I change the grid to use the traditional approach, linking both tables directly, there is no apparent delay when changing records in MASTER.

>Both tables are properly indexed, have no relations set and no triggers.
