>>>I have a VFP 8 application that runs the following query in 0.01 seconds. When I run it in VFP 9 SP1, it takes about 7 seconds:

>>>INTO CURSOR Sql1a

>>>I read that VFP 9 SP1 corrected the problem with the STR() function not being optimized with Rushmore. Is there a similar problem with TRANSFORM() and/or TTOC? Do you have any ideas to speed up the query without recreating a new index?

See this thread Re: Index optimizing in SP1 Thread #1059937

I also found that you already asked a related question while back.
