Hi, I have 2 tables, one containing jobs and the other locations.
the jobs have a start and stop location field using the keyid of the locations.

e.g.
job:
key  start stop
1:     2      3

location:
key  description
1:     test1
2:     test2
3:     test3

What i want is to return:
job id:1 start:test2 stop:test

Hope that makes sense, only need the query..

Can anyone help please??

You need to double join the location table:

select j.key, l1.description as start, l2.description as stop
from job j, location l1, location l2
where j.start = l1.key
and j.stop = l2.key
