i was wondering why this one does not work?
DateDiff("d",dbo.Table1.regdate,IIf(IsNull(dbo.Table1.compdate),GetDate(),dbo.Table1.compdate)) As Days
Where blah blah...
it supposed to get the difference of 2 dates namely regdate and compdate. but if compdate is null replace compdate with the date returned by GetDate() function.
this one works with Access 2000 crosstab queries, but not on SQL Server 7.0.
thanks in advance,
