Grabbing value from a different table, based on results from current table...

Hi guys, I'm trying to do something like;

SELECT pmtext.pmid FROM pm WHERE pm.userid = 3312

.. but its giving me an error.

Basically, I just want to select pmtext.pmid, based on the results for "WHERE pm.userid = ...".

Anyone got any ideas? My head is really hurting today Frown

TIA

Hi,

You need to join the tables:

select pmtext.pmid
from pm, pmtext
where pm.a = pmtext.b and
pm.userid = '....';

You need to look at how the tables are joined, and fill in the a and b. =)

Cheers,

Alex
