Hi Cameron, It will take a long time unless you have some indexes on your fields - even then depending on how much data you have :) Echo out the query it's running and speed that up - using 'explain' is the easiest way to work out what's going on. See http://www.postgresql.org/docs/7.4/static/indexes-examine.html for more info on explain. You'll most likely need to add an index on whichever field gets compared for startdate and enddate (at least) .... Apart from that without seeing the proper query it runs and the database table schema we're just guessing.

Wow this script take a long time to execute. Why is it takeing so long? Is there a better way to do this? -Cameron -----Original Message----- From: Chris Smith [mailto:chris@xxxxxxxxxxxxxx] Sent: Monday, March 01, 2004 5:41 PM To: Seader, Cameron; pgsql-php@xxxxxxxxxxxxxx Subject: RE: [PHP] pg_fetch_row Problem Hi Cameron, Excellent :) The max timeout is a PHP thing - see http://www.php.net/manual/en/function.set-time-limit.php Chris. -----Original Message----- From: Seader, Cameron [mailto:CSeader@xxxxxxxxxxxxxx] Sent: Tuesday, March 02, 2004 11:34 AM To: Chris Smith; pgsql-php@xxxxxxxxxxxxxx Subject: RE: [PHP] pg_fetch_row Problem Chris, I tryed this out and it works great thanks, but now i get this message. Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/html/PMS/csv_export.php on line 41 Know where i can set execution times? is this for PHP or PostgreSQL? Thanks, Cameron -----Original Message----- From: Chris Smith [mailto:chris@xxxxxxxxxxxxxx] Sent: Monday, March 01, 2004 5:17 PM To: Seader, Cameron; pgsql-php@xxxxxxxxxxxxxx Subject: RE: [PHP] pg_fetch_row Problem Hi Cameron, I think the reason is you're going beyond the number of results you have for that query. Rewrite the while(...) loop to look like this: $result_count = 0; while($result_count < $count) { $row = pg_fetch_row($result, $result_count); ......... } See if that works.
