>I have a table that is part of a DBC. It has over 1 million records. When I run the following query in the VFP 8.0 command window, the results come back immediately. Running the same query on the same table in VFP 9.0, the query takes around 6 seconds to run. There is an index on the table for "cUoCode + cFtcCentury + cFtcCode + TRANSFORM(lFtdAdversary, "Y") + cFteCode + STR(iFtfEntry) + TTOC(tFtfEntered, 1)". Is there anyway to speed this query up, like it was in VFP 8?

Because of the bug in VFP9, the indexes with STR() function are ignored by Rushmore if SET ANSI is OFF. A worcaround is either to SET ANSI ON or replace STR() WITH PADL(,10).
