I can't seem to get this working: - $query = "SELECT c.c_id,c.c_name, COUNT( p.recipe_title ) as theCount
-
FROM new_recipe_cat AS c
-
LEFT OUTER JOIN new_recipes AS p ON c.c_id = p.c_id
-
WHERE (c_id==11 && c_id==12 && c_id==13 && c_id==14
-
&& c_id==15 && c_id==16 && c_id==17 && c_id==22
-
&& c_id==23)
-
AND r_allow=1
-
GROUP BY c.c_name";
The where clause isn't working and it's throwing an error: Warning: mysql_fetch_arr ay(): supplied argument is not a valid MySQL result resource
Any ideas on how I can fix this?
Thanks

Yep, you should always check mysql_error() when there is an error in a MySQL query.
However, I would guess that your problem is with the "c_id==11" checks. There is only supposed to be a single "=" in there. SQL does not use two "=" chars like most programming languages do.

Right, I was working with an if clause earlier and the two == was stuck in my mind.
I tried a few various ways of working the WHERE clause but it just wasn't doing it for me. I used the mysql_error, but it wasn't throwing an error. It just didn't return anything or something that I didn't want. Oh well, I just went back to using an if clause. It list what I want just not in alphabetical order.
I appreciate all the help. Thanks.

No problem.
One thing that I don't get though. You used && (and) between all those checks. Are you sure you didn't mean to use || (or)? - Using && your c_id would have had to match all of the numbers per row to return it (which doesn't make sense. Presumably it only has one value).
You could try the IN() function. - Something like: - WHERE c_id IN(11, 12, 13, 14, 15, 16, 17, 22, 23)

I have a SQL query I'm invoking via VB6 & ADO 2.8, that requires three

Using three "Left Outer Joins" slows the system down considerably.
I've tried creating a temp db, but I can't figure out how to execute
two select commands. (It throws the exception "The column prefix

I have two tables that are pretty big. I need about 10 rows in the

seems when I join the tables in the FROM clause, I have to filter my

This seems like it would cause a lot of overhead especially when my
left table is ten thousand rows. Am I wrong in thinking that the two
