I have this query

SELECT tblRefit.ID, tblRefit.Car, MAX(tblRefit.Date) AS LastDat
FROM tblRefi
GROUP BY tblRefit.Car

and I get the error "You tried to execute a query that does not include the specified expression <name> as part of an aggregate function. (Error 3122)

I can't see what is wrong with my SQL
 
Hi,


Using a GROUP BY clause, or an aggregate in the SELECT clause, each
expression in the SELECT clause must either be in the GROUP BY list, either
be aggregated ( SUM, MIN, MAX, FIRST, LAST, COUNT, ... ), either an
arithmetic expression involving the previous two.


If you do not use a GROUP BY clause, but use an aggregate in the SELECT
clause, there is implicitly ONE group made of the whole data ( that will
generates just one record).



Hoping it may help,

Try:

SELECT tblRefit.ID, tblRefit.Car, MAX(tblRefit.Date) AS LastDate
FROM tblRefit
GROUP BY tblRefit.ID, tblRefit.Car;
