>One thing you absolutely do not want to do is add a UDF to a SQL query. VFP will run the UDF with every row of the source cursor, which KILLS performance.
I tried a UDF that deleted records. I thought that placing the UDF after another condition (with AND) would make it run only if the other conditions returned .T. Wrong!
Fortunately, I didn't try this with production data.
What I finally ended up doing is use the subquery approach to get me the PK of each record, and then send the PK to my UDF.
