case of concurrency. In Oracle databases, DML locks mainly include TM and TX locks, where TM locks are called table-level locks, and TX locks are called transaction or row-level locks. When Oracle executes DML statements, the system automatically requests a TM-type lock on the table to be operated on. When the TM lock is obtained, the system automatically requests the TX type of lock and resets the lock flag bit of the data row that is actually locked. In this way, checking the compatibility of
