Re: WHERE on an alias

Joseph,

> playpen=# SELECT a, sum(b) as dsum
> playpen-# FROM taba
> playpen-# GROUP BY a
> playpen-# HAVING dsum > 5;

Sorry, my mistake:

SELECT a, sum(b) as dsum
FROM taba
GROUP BY a
HAVING sum(b) > 5;

I had the impression that aliases for aggregates were allowed in
Postgres HAVING clauses. Apparently not.
