Hello All,<br />
I am new to SQL and trying to write a select query to get a result from 2 table. Table1 is CONTACTS and 2 is USERS. CONTACTS has a field named Assigned_user_ID, which should have the same value as field ID in USERS.

I want to get a list of those records which do not match in both tables. I have come up with this code, which doesn't give me any results. However, it doesn't give me any error either. Please see the code. <br />
Many Thanks<br />
