Okay, granted, your design has to be sound (ie. indexing) and the SQL statement has to be optimized...and it depends what you are trying to do...but, I haven't found too many cases where an **optimized** SQL statement has been noticably slower than SEEK and SCAN...I haven't worked with 11,000,000 record tables (at least not in FoxPro), so I can't really comment on that situation...
