Andrus,

I'd say the other way, I think "SQL Server" to most people here means some version of Microsoft SQL Server. Usually other backends are called out by name: Oracle, Sybase, MySQL, Firebird, etc.

>My goal is to create VFP application which upsizes data to SQL server simply by running it by customers.

That's a not so trivial feat to accomplish. I'm sure there are enough idiosyncratic differences beween each backend that you'd have a fair amount of CASEing in your code. Good luck with it.
