SELECT ID,COUNT(*) AS CNTR
FROM TABLEA ,
TABLEB
WHERE AN_ID = BN_ID
AND AN_MTH = 01
GROUP BY AN_ID
HAVING SUM(AN_AMNT) > 100 ) C;

I understand you wanted to count number of records which is present in table for the below where condition & having

Code:

 SELECT COUNT(*) AS CNTR FROM TABLEA , TABLEB WHERE AN_ID = BN_ID AND AN_MTH = 01 GROUP BY AN_ID HAVING SUM(AN_AMNT) > 100


Why dont you try the above

So using "A.ID" instead of "ID" for Table-A solved the problem?
