is used in queries with a LIMIT clause for updating. 0 =
NO = Prohibit update of a VIEW, which does not contain a
key of the underlying table and the query uses a LIMIT
clause (usually get from GUI tools).
--wait_timeout=# The number of seconds the server waits for activity on a
connection before closing it.
