Hi,
How do you compare the speed between two SQL Select expressions?
Typically I would do it like this:
nStart = seconds()
select * ......
nEnd = seconds()
nTime = nEnd - nStart
What I am not sure is how do you account for the fact that the 1st SQL Selects creates some data buffer (I think it does but I am not sure). So, if the buffering assumption is correct, the 2nd SQL Select will have an advantage.
Another approach, I think, is to do 1st SQL Select. Then, shut down VFP and on the next start to do 2nd SQL Select only.
Any suggestions or comments?
