>>>My theory is that if I change this behavior and instead of using a SELECT statement against a REMOTE VIEW like a direct select within the Visual foxpro environment, I change this and send a SQLEXEC to the backend and store the data on a TEMPDB table, then the second step, instead of using the SCAN and SQLEXEC command for each one of the records on the cursor to insert it to the back end i use a BULK insert using a INSERT INTO theTable SELECT * FROM #TempTable this would improve the speed a lot

Check it. I think it should work but I have no VFP6 installed here and have no Help for it.
