Question

I have this SQL code here..

SELECT cl.clientid,
       cl.clientname,
       cl.billingdate,
       cp.startdate,
       cp.expiration, 
       (SELECT COUNT(*)
            FROM invoice 
            HERE client = cl.clientid) AS invoicecount  
FROM client cl
INNER JOIN clientplan cp ON cp.client = cl.clientid
WHERE cl.isbilled = 1 AND expiration is NULL AND expiration > '2012-06-22'

My problem is that a client could have 3 client plans and they either have an expiration date or the expiration is NULL. I am trying to get the rows that are not expired or are NULL.

What am I doing wrong?

I’m not sure, but isn’t what you want this :

SELECT cl.clientid, cl.clientname, cl.billingdate, cp.startdate, cp.expiration, 
(select count(*) from invoice where client = cl.clientid) as invoicecount  
FROM client cl
inner join clientplan cp on cp.client = cl.clientid
where cl.isbilled = 1 and (expiration is NULL or expiration > '2012-06-22')

With an or instead of an and on the expirations. Because expiration cannot be null and > ‘2012-06-22’…
