Well, actually Ed's right so it's (of course, what was I thinking!) 
not going to work in this situation, but for completeness' sake, in a 
single environment, ie where the SQL is getting executed in the same 
"place" that the UI is running, you'd have SQL something like

    SELECT x,y,z FROM t WHERE [your where-clause stuff] AND z() ...

The function Z returns true so that it doesn't act as any kind of 
filter, but it contains code that does the onscreen reporting.
See, horrible old style thinking.  Except, of course, what's a UI for 
if not interfacing the user to the processes... :-)

I'm being slightly sarcastic it's true (I am British after all), but 
I still think in essence Ed's right about the UI/database layer 
interaction
