无法删除表

#这可能是MySQL在InnoDB中设置了foreign key关联，造成无法更新或删除数据。可以通过设置FOREIGN_KEY_CHECKS变量来避免这种情况。

mysql>SET FOREIGN_KEY_CHECKS = 0;

Query OK, 0 rows affected (0.02 sec)

mysql> delete from repositories where repo_name = "watch/sinawatch_agent_update";

Query OK, 1 row affected (0.02 sec)

mysql> SET FOREIGN_KEY_CHECKS = 1;

Query OK, 0 rows affected (0.00 sec)
