How to use the MAX DATE condition in WHERE CLAUSE FILEDS

Question

Hi,
I am trying to fetch the result for getting maximun date but when i try to execute the query i am getting the error as follows.
CONDITION : trunc(max(RD.DATERECEIVED)) BETWEEN TO_DATE('01/08/2011','DD/MM/YYYY') AND TO_DATE('01/08/2011','DD/MM/YYYY')
ERROR: Group function is not allowed here.

I see a couple of problems here.
First, what you posted below is not a syntactically valid query. It seems to be part of a larger query, specifically, this looks to be only the GROUP BY clause of a query.

Hi,
I Have a group function in the Query. Below is the Query i have used it,
GROUP BY S.FREIGHTCLASS,
R.CONTAINERKEY,
S.SKU,
S.DESCR ||S.DESCRIPTION2,
S.PVTYPE,
RD.LOTTABLE06,
R.WAREHOUSEREFERENCE,
RD.TOLOC,
R.ADDWHO,
R.TYPE,
S.CWFLAG,
S.STDNETWGT,
S.ORDERUOM,
R.ADDDATE,
C.DESCRIPTION,
(CASE WHEN P.POKEY LIKE '%PUR%' THEN 'NULL' ELSE to_char(P.PODATE,'dd/mm/yyyy') END),
NVL((CASE WHEN R.ADDWHO='BOOMI' THEN RDD.SUPPLIERNAME END),SS.COMPANY),
RDD.BRAND,
S.NAPA,
RD.RECEIPTKEY,
R.SUSR4,
P.POKEY,
RDD.SUSR1,
r.STATUS, DECODE(RDD.SUSR2,' ',0,'',0,RDD.SUSR2),
rd.SUSR3Second, the answer to your primary question, "How do I add a predicate with with a MAX() function to my where clause?" is that you don't. As you discovered, if you attempt to do so, you'll find it doesn't work. If you stop and think about how SQL is processed, it should make sense to you why the SQL is not valid.
If you want to apply a filter condition such as:
trunc(max(RD.DATERECEIVED)) BETWEEN TO_DATE('01/08/2011','DD/MM/YYYY') AND TO_DATE('01/08/2011','DD/MM/YYYY')you should do it in a HAVING clause, not a where clause:
select ....
  from ....
where ....
group by ....
having max(some_date) between this_date and that_date;Hope that helps,
