I have this query:

Code:
$sql = "
	SELECT unbilled_item.job_number,
	SUM(unbilled_item.amount) AS total_unbilled,
	job.project_manager
	FROM unbilled_item
	LEFT JOIN job ON (unbilled_item.job_number=job.job_number)
	GROUP BY job.project_manager
	ORDER BY total_unbilled DESC
	" ;
Is it possible to add something like:

Code:
WHERE user.office = "xxx"
???

I can't work it out.
