Hi all,

We know the Select-SQL command when a view is used and we have control on rushmore optimization level by creating expressions, but I don't know whether we have a way to know what VFP does when updating tables based on parameterized views, I mean, when we do a TableUpdate()

Sys(3054,1) reports Rushmore optimization levels when selecting and updating records from tables based on views but it may report that different indexes are being used.

I think that Update-SQL's WHERE Clause is built on a Field by Field basis (View Designer: "SQL Where clause includes Key Fields Only") , not expressions, is this correct ?

Thanks

Juan C.
