Hello,

I have few set of questions for the PGSQL list users

Q 1. Consider the following query, suppose I want the sum of the
tickettabcount and ticketmultabcount, how do I modify my query to get the
same. If I use operator "+" in between these, it's been ignored by the
PgSQL and throws a error!!

QUERY
-----
select count(tickettab.tokenid) as tickettabcount,
(select count(tokenid) from ticketmultab
where agentid='danny' and arrivaldate='2001-11-12') as
ticketmultabcount
from tickettab
where tickettab.agentid='danny' and
tickettab.arrivaldate='2001-11-12'

RESULT
-------


tickettabcount  || ticketmultabcount
-------------      ------------------
9                   2




Q 2. I join two tables, I get a result set which has values from
both the tables, now if I want to sort the combination of the result
set how do I do that!!, not the individual table result set.

Hoping for positive reply, thanks!!
