Sir, I don't see anything wrong with the syntax in your query. If I
haven't over looked something, and if you haven't misspelled
anything, then you have a data problem. Since your first query
returns a Cartesian product, you should get something if the WHERE
clause returns >= 1 row for each table. So either there are no rows
in q that meet the conditions
q.active = '1' AND q.global = '1'
or there are no rows in c that meet the condition
c.active = '1'
Run the first query with only the first WHERE condition. If you get
rows, add the second condition. If that works, add the third. The
point at which the query stops returning rows is the point at which a
subset of your WHERE conditions aren't met by the any of the rows in
one of the tables.
BTW, why are you putting quotes around numbers? I'm assuming that's
not the problem, since you say you did it in the query that worked,
but I don't see the point.
