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` =
'0000-00-00' 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

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?

Yes I have checked that $last_mailing_date contains a date.

I was wrong, It doesn't work when it is live. I had only ran the first
query before I added the "AND NOT" portion, sorry.

Try changing: "AND NOT `Bible_trivia_category_reference` = ( SELECT ..."
to "AND `Bible_trivia_category_reference` != ( SELECT ..."
