Re: [MS_AccessPros] Seems Simple

 

Paco-


You can find the answer in our upcoming Effective SQL book.  What you need is:

SELECT tblShop.*, (SELECT COUNT(Shop) FROM tblJob WHERE tblJob.Shop = tblShop.Shop) AS JobCount
FROM tblShop;

I have 2 tables:  Shop and Job. I need a query that will return a count of jobs, by shop. The problem is that sometimes for a given date range, the shop has no jobs. If I join the tables on Shop (FROM tblJob RIGHT JOIN tblShop ON tblJob.Shop = tblShop.Shop), the shop that has no jobs isn't included in the record set. I need to include the shop with a count of zero.


I've drawn a blank (although I'm certain I have resolved this before).


Any ideas?
