Look under the ANSI website for the L8 committee if I remember correctly.

The aggregates are designed to work on columns while the procedural function code is designed for row at a time execution. And the 4GL stuff like T-SQL are usually pretty dumb compilers -- one pass, direct code interpreters without optimizers.

I think most of my tricks are clear -- of course I worked with OS/JCL programmers who thought that thing was easy reading. I do have a big gripe about that fact that people do not comment SQL code like they would procedural code.
