Arno,



Thanks for your pointing out the issue with my SQL statement.

Hi,



The message doesn’t tell you which expression is not contained in an aggregate function or GROUP BY clause, but is very clear that it is “P.PHONE_ID”



Not sure what you trying to achieve, but your SQL is indeed invalid, because there can be multiple PHONE_ID’s per AREA_CODE, PHONE_NO



Kind Regards,
Arno Brinkman

Dynamic SQL Error SQL error code = -104 Invalid expression in the select list (not contained in either an aggregate function or the GROUP BY clause)
