GROUP BY Problems

GROUP BY Problems

GROUP BY Problems

I have two tables, say Customers and Invoices and I want a query to show some customer information along with the # of invoices they have...

From what I understand a group by fields list must also be included in the GROUP BY ...

So this works fine:

SELECT c.cust_no, COUNT(*)
FROM "customers" c, "invoices" i
WHERE c.cust_no=i.cust_no
GROUP BY c.cust_no

SELECT c.cust_no, c.cust_name, COUNT(*)
does not

So how can I also have fields like cust_name, cust_city etc returned along with the # of invoices?
