[PHP-DB] Broken query
I am trying to write a query to select a trivia question, but I don't want the trivia question category to be the same two days in a row so I added a second SELECT syntax to find out what category was used yesterday. This works when I test it live, but doesn't work when it is part of a cron job. How do I get the value of `Bible_trivia_category_reference` from the second SELECT query to be used in the first? What change is needed? Ron SELECT * FROM `verse_of_the_day_Bible_trivia` WHERE `assigned_date` = '-00-00' AND `seasonal_use` = $bible_trivia_application AND `live` =1 AND NOT `Bible_trivia_category_reference` = ( SELECT `Bible_trivia_category_reference` FROM `verse_of_the_day_Bible_trivia` WHERE `assigned_date` = '$last_mailing_date' LIMIT 1 ) ORDER BY RAND() LIMIT 1 -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Broken query
How is the last mailing date variable set? Have you tried printing out the queries that are run when it is run manually and when it is run as a cron to find any differences? -patrick On Jul 11, 2010 8:23 AM, Ron Piggott ron.pigg...@actsministries.org wrote: I am trying to write a query to select a trivia question, but I don't want the trivia question category to be the same two days in a row so I added a second SELECT syntax to find out what category was used yesterday.
