ORDER BY cam.id ASC

When I strip the "AND cam.id IN ()" part, it executes.

Why does this happen, although I have fully qualified the column (i.e. "cam.id" instead of "id")?

Things I tried:

• removing the "AND cam.id" clause --> statement executes without error
• using "campaigns.id" instead of "cam.id" --> error 1054 / "unknown column in where clause"
• UPDATE it works, if I have only a few (say 5) items in the IN clause

Answer 1

I think that the root of the problem is in the following line:

 AND cam.id IN
