To you John and Walter who love to debate anytime,

Sorry for jumping in but my question is something not quite irrelevant on this issue. When do you use VFP/SQL Server combination and when it is not? In the same way, apply the same question to VB/SQL Server (specific to John as I assume that Walter don't use VB.)

I know this may be a rude wakeup call, but there it not too much that you can do in VFP that could not be replicated in SQL. I don't count all the set relation stuff in this because that is truly an x-base thing. However, ADO Shaped Recordsets do give me the identical behavior. So, if pressed, I could do that as well.

Often, I find it very effective to render results from SQL into a VFP cursor, and index that cursor to provide an easy way to sort data. I find I only need to do this when I am using a Grid. Remember, with client-side ADO recordsets, I can sort the data just as easily, without round-tripping to the server.
