Query Syntax - NULLS

I'[m trying to exclude 'NULLS' from MAX(l.DATE_WORK) but this doesn't exclude them.

SELECT j.JobID, j.DSCR, j.JSTATUS, MAX(l.DATE_WORK)
FROM job j
LEFT JOIN labor l ON (l.JOB_ID = j.JOB_ID)
GROUP BY j.JOB_ID
ORDER BY l.DATE_WORK
AND MAX(l.DATE_WORK) IS NOT NULL;

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Use this query...

SELECT j.JobID, j.DSCR, j.JSTATUS, MAX(l.DATE_WORK)
FROM job j
LEFT JOIN labor l ON (l.JOB_ID = j.JOB_ID)
where l.DATE_WORK is not null
GROUP BY j.JOB_ID,j.DSCR, j.JSTATUS
ORDER BY l.DATE_WORK;
