>Is there a place on the web for a good ref. for SPT SQL syntax? I am converting some old VFP stuff using SPT and the same syntax doesn't work. Unfortunately this is my first project using ODBC and SPT. I looked through the help file and didn't find very much info.

No. With SPT you are sending a literal string to a back-end database, which it then interprets and (hopefully) executes. You must format the string so the back-end understands it.

Most back-ends are ANSI SQL compliant (e.g. SQL-92) but this is not universal, and they all have their own foibles. In short, different back end, (often) different SPT.

This is a good reason to use n-tier design and set up a data access tier, to limit the places you have to make changes if your back-end changes.
