The object that is locked by the LOCKING modifier does not have to be referenced in a subsequent SQL request.

A lock can be executed separately from the SQL request that it precedes. Therefore, a LOCKING modifier must reference the object on which a lock is being placed. The objects referenced in the SQL request have no effect on the execution of a LOCKING modifier.

When a LOCKING modifier references a view, the specified lock is applied to all underlying base tables. For example, if a view refers to tables t1 and t2, then a lock on that view would apply to both tables.

LOCKING DATABASE is the only way to lock a database or user.
