Re: Evaluate date field, use only if not null/empty in query.

Thanks Volker,

So after looking at the NULLIF function help section,

if the LastReqTime = '' , NULLIF will return a null to the query,

which I assume will stop the processing. If LastReqTime isn't

empty, LastReqTime will be returned to the query and the

processing will continue.   TBH, I was trying to come up with

CASE/IF statements on my own, and not having much luck,

but your suggestion is elegant in its simplicity, which is how

I like to code; the fewer moving parts the better!
