You took the first thought that came to my mind and put it into words
<smile>.  Or, why not use SETLL for better performance?

My later thoughts degraded to the cynical.  Like, why do people insist in
looking beyond the obvious?  Or, go ahead and try to find an SQL equivalent
to SETLL.  Or, maybe the question pertains to the elusive challenge of
platform independence?

Anyway, good question.
