Understanding of the use of the last_insert_id () function provided by MySQL

LAST_INSERT_ID () is a value that MySQL provides to return the last insert or update query set to the Auto_increment column in the current client

LAST_INSERT_ID () is not affected by other clients, so is thread-safe, the current client can only get the current client's latest value, no need to lock processing

The usergeneratedkeys= "true" keyproperty= "id" in MyBatis is probably implemented using the last_insert_id () function.
