今天删除出现了这个异常：

1217 - Cannot delete or update a parent row: a foreign key constraint fails_外键关联

主要是有外键关联了。可以临时设置一下：

SET FOREIGN_KEY_CHECKS = 0;

执行完了再记得设置回来：

SET FOREIGN_KEY_CHECKS = 1;

其实我们从一些客户端导出 SQL 的时候也带了这个 SQL：

1217 - Cannot delete or update a parent row: a foreign key constraint fails_SQL_02
