I need to the following query:
select distinct event_code, level from logs join stat on (stat.prime is not
null) where order_num = 130680;
Ok, no problem. Does exactly what I want; however, I need to sort this is a
particular way to get the right results. When I try to add the order by
clause, I get an error. Here is the ORDER BY:
ORDER BY event_date DESC, event_time DESC, event_secs DESC
If I put this where I thought it should go as in:
select distinct event_code,level from logs join stat on (stat.prime is not
null) where order_num = 130680 order by event_date,event_time,event_secs;
I get the following error:
ERROR: For SELECT DISTINCT, ORDER BY expressions must appear in target list
No matter where I put it I get errors. Obviously, I'm a novice. Can somebody
give me any advice? I'm using Postgres 7.2.3 on RedHat.
Thanks...
