If I could figure out how to structure the query, I would be happy to do so. The problem is that I am working with 3 different tables for this. Additionally, I ran into a brick wall when trying to structure the query to remove/eliminate the entries in the exclusion table. The exclusion table has 13 entries currently, and the last thing I tried with the query was outputting 13 entries of every system. Here is the query that was yielding this... #$query = "SELECT AllMid_Data.CPU_Hostname FROM AllMid_Data, exclusion # WHERE AllMid_Data.CPU_IN_SVC = \"Y\" # AND AllMid_Data.CPU_DNS = \"sbcld.sbc.com\" # AND AllMid_Data.CPU_Hostname != exclusion.hostname # ORDER BY CPU_Hostname ASC"; Scott Nipp Phone: (214) 858-1289 E-mail: sn4265@xxxxxxx Web: http:\\ldsa.sbcld.sbc.com -----Original Message----- From: Bastien Koert [mailto:bastien_k@xxxxxxxxxxx] Sent: Monday, March 28, 2005 11:13 AM To: NIPP, SCOTT V (SBCSI); php-db@xxxxxxxxxxxxx Subject: RE: RE: Further MySQL query problems... why wouldn't you just run a query to return only the elements that you want?
