Hi Sergey,
I inserted in the wrong order. I meant "Thanks to VFP9" based on the ability to do UPDATE FROM x JOIN (SELECT * ) ON type of SQL code. I don't think this was possible before 9. But with regard to the structure, yes, CAST is good. I just wanted folks to know IIF(x = y, 0, x) in VFP SQL code won't always work as expected.
