Any of you fifth columnists out there care to rub Bobs nose in this query?

I reckon I have graced his killfile and the query was buried so deep in my response to his rant that he prolly would not have even seen it if he had read the post.

It was his challenge and it seems he doesn't have the gonads to stay in the kitchen long enough to see the be warned he is unlikely to respond meekly :-).

Or if you think the query is a dud let me know - it works on ASE 12.x and I presume it is generally viable on other SQL engines.
