Select where table1 not in table2

I have 2 tables.

Table1 is made of 2 primary keys, table_id and job_id along with a bunch of other values (lets just use job_name for now).
Table2 is made of 2 primary keys, table_id and job_id along with a bunch of other values (Don't care what for this example).

I need to select the job_name from table1 where that entries table_id and job_id are not in table2.

How can I do this?  I was using an outter join when I wanted table 2 with table 1 but now that I only want table1 when there is no matchig entry in table 2!!

Thanks!

That did it!  Thanks.  What does select 1 mean anyway?

Just the constant number 1. In the EXISTS clause the list of fields returned by inner SELECT doesn't matter because EXISTS() just checks whether there is a record returned by the SELECT statement no matter what columns included.
