Subj:   Re: Interval in a where clause
 
From:   Victor Sokovin

          Select
              StartDateTime
              ,EndDateTime
              ,(EndDateTime - StartDatetime) DAY(4) as Difference

          From MyTable

          Where Difference <= 7
  Now this returns a 5407 error which is expected because the result set is an INTERVAL  



Try to "extract" the days from the interval:

     where EXTRACT(DAY from (Second_EntryDateTime - First_EntryDateTime DAY(4)=)) <= 7 .

In a similar way it is possible to extract all elements from dates and intervals.


Regards,

Victor
