MySQL 8.3 Reference Manual  /  ...  /  Replication of DROP ... IF EXISTS Statements

19.5.1.11 复制DROP ... IF EXISTS语句

该DROP DATABASE IF EXISTS、DROP TABLE IF EXISTS和DROP VIEW IF EXISTS语句总是被复制，即使源数据库、表或视图不存在。这是为了确保要删除的对象在源和副本上都不再存在，一旦副本赶上了源。

DROP ... IF EXISTS语句对于存储程序（存储过程和函数、触发器和事件）也是被复制的，即使源上的存储程序不存在。
