>Hello all,

No, the 2 Gig DBF file limit will remain.

What do you mean by SQL being way too slow? I think its query performance is quite optimized. In terms of ODBC capabilities, I can have a VFP remote view to SQL Server pull thousands of records in a couple seconds. That seems pretty fast to me!

Tip: Try this technique to speed up remote views that return large result sets:

USE myview
GO BOTTOM
LOCATE

--OR--

SELECT MyView
REQUERY()
GO BOTTOM
LOCATE

That actually pulls the records faster by forcing synchronous execution or something.

Also, limiting the result set by an optimizable filter expression helps immeasurably.
