You'll need to get a bit creative with how you test these in their native environment (i.e. SSMS) though. Usually, my testing is strictly for performance and data-quality issues and is confined to SQL statements needed specifically for the application. Hope this helps! -Tod Hi Ive,

In short, for variables, you would declare (and set) your variables first and then use the “?Parameter” syntax in the SQL Statement. You’ll need to get a bit creative with how you test these in their native environment (i.e. SSMS) though. Usually, my testing is strictly for performance and data-quality issues and is confined to SQL statements needed specifically for the application.

Hope this helps!

Have been a VFP (and FoxBase/FoxPro) programmer for 20 years but only recently have gone back to using VFP with SQL backends. Question, in your excellent examples above, how does one use metadata if your SQL commands require input and out parameters? This would be quite common I imagine especially when using parameters to update existing records in an SQL backend. Kind Regards, Ive. Gee I’m so glad I found this blog.

Especially if there is (or might be) a need to use a different database or UI. I loved your business object demonstrations and the concept of "passing the buck". It helped me put some theory around the practices I have been getting used to over the years.

I take the exact same approach--using metadata--in my n-tier designs. I demonstrated this at FoxForward this year and of course the downloads from that--including the source code with the sqldefs.dbf metadata table--are available from Ed Leafe's ProFox downloads site: http://leafe.com/dls/vfp (see "Designing in N-Tier fashion"). It's always best to decouple when you can (without introducing much complexity). Even since the conference I've seen other areas in that project where I could decouple even more---specifically for adding temporary indexes. If I'm not mistaken, Andy Kramek does something extraordinary with decoupling, where virtually most of the code is meta-data! I'm guessing he's relying heavily on EXECSCRIPT? Neat. Cool stuff! --Michael Great concept, Todd. I take the exact same approach–using metadata–in my n-tier designs.
