My, there's a lot of misinformation in this thread.
The reason there's no error thrown is that the reference to mov_id in
the sub-SELECT is a perfectly legal outer reference to the mov_id column
available from the upper SELECT. If the column truly did not exist
anywhere in the tables used in the query, it would have thrown an error.
