推荐答案
锁定释放规则
释放会话持有的表锁时，它们将同时释放.会话可以显式释放其锁，也可以在某些条件下隐式释放锁.
When the table locks held by a session are released, they are all released at the same time. A session can release its locks explicitly, or locks may be released implicitly under certain conditions.
-
会话可以使用UNLOCK TABLES显式释放其锁.
A session can release its locks explicitly with UNLOCK TABLES.
如果会话发出LOCK TABLES语句来获取锁，而已经持有锁，其现有锁被隐式释放在授予新锁之前.
If a session issues a LOCK TABLES statement to acquire a lock whilealready holding locks, its existing locks are released implicitlybefore the new locks are granted.
如果会话开始事务(例如，使用STARTTRANSACTION)，则执行隐式的UNLOCK TABLES，这会导致现有的要释放的锁.
If a session begins a transaction (for example, with STARTTRANSACTION), an implicit UNLOCK TABLES is performed, which causesexisting locks to be released.
