Answer Posted / lb14447
The sql query would be
SELECT * FROM EMPTEST WHERE EMP_ID IN (SELECT EMP_ID FROM EMPTEST GROUP BY EMP_ID HAVING SUM(EMP_IND)/COUNT(EMP_IND) = 0
OR SUM(EMP_IND)/COUNT(EMP_IND) = 1);
Datastage implementation:
SRC --> CPY ----> AGG---> FILTER

--------> Look up ----> TGT
In the Aggregator stage calculate the Sum and Count fields.In the filter stage bypass the unwanted records using Sum and Count calculated in Aggr stage.
