Crosstab query Help
A crosstab supply new field based on values stored in a field. Since you
don't have MTime1, MTime2 and MTime3 as values, already, a crosstab is not really the solution to use. If it was not for MTime2, a possible solution could have been: SELECT theDate, Location, Plate, MIN(MarkTime) AS MTime1, MAX(MarkTime) AS MTime3 FROM myTable GROUP BY theDate, Location, Plate (and there will be also the problem that MTime3 can be equal to MTime1, rather than being null, as you have sketched the desired result, but I assume this is not a major problem). Sure, if you can use the AVERAGE rather than a third time, for MTime2, that would be already almost done: SELECT theDate, Location, Plate, MIN(MarkTime) AS MTime1, AVG(MarkTime) AS MTIime2, MAX(MarkTime) AS MTime3 FROM myTable GROUP BY theDate, Location, Plate but if there is more than three MarkTIme, for a plate, for a given date, what we do, as example, if there is a fourth record about Plate=12AB for 02/23/2007 ?

Crosstab query Help
Michel,
Thank you for reply, i agree that it possible to have fourth record with the same plate and location and different marktime... But any way how to achive the output result in that case?

Crosstab query Help
Try this SQL
TRANSFORM First(t.MarkTime) AS FirstOfMarkTime SELECT t.MarkDate, t.Location, t.Plate FROM t GROUP BY t.MarkDate, t.Location, t.Plate PIVOT "MTime" & DCount("*","t","Location='" & [Location] & "' AND MarkDate=#" & [MarkDate] & "# AND MarkTime =#" & [MarkTIme] & "#"); -- Duane Hookom Microsoft Access MVP "elena" wrote: Michel, Thank you for reply, i agree that it possible to have fourth record with the same plate and location and different marktime...
