Help with SQL syntax

Hi, I am trying to find records in one table that do not have matchin entries in another table. I have done this before in Access but cannot get it to work with Informix. Here is the syntax I am using. SELECT account.acc_name, account.password FROM account, OUTER temp WHEREaccount.acc_name = temp.acc_name AND temp.acc_name IS NOT NULL Can anybody tell me where I am going wrong. In the manual it says that there should be a null entry in the 2nd table which is what I would expect but I still can't get it to work. Thanks in advance. Dean Hobbs deanh@unipalm.pipex.com
