Locks a database, table, view, or row at the specified severity, overriding the default locking severity that the system places for a request. With the appropriate privileges, you can place this lock to upgrade or downgrade the default lock.
In addition to DML statements, you can also specify the LOCKING modifier with DDL statements including CREATE VIEW, REPLACE VIEW, CREATE RECURSIVE VIEW, REPLACE RECURSIVE VIEW, CREATE MACRO, and REPLACE MACRO. You can use the LOCKING modifier to override the default locking severities and prevent deadlocks.
