Re: SQL Inspiration needed

[Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx>]

I don't understand your point.

I could absolutely do this faster in RPG, as could just about anybody on 
the list.  Jon asked for an SQL option, and I explained there were no 
good ones.  Anything iterative that relies on data to determine the next 
iteration doesn't work well in SQL, as your example shows (like it or not).

Seriously, I am a big fan of SQL.  As I am of most of the tools 
available on the i when used properly.  This just isn't one of those cases.
