Well, it''s a guess. A "CREATE VIEW" follows the line that specifies
the warning. (An "ALTER TABLE" immediately precedes it.) This made
me think that is was on a view; then I went through the views till I
found one with a column called "collection". Is there another way I
can isolate what's happening?
