MySQL 的 Safe Update Mode

删除mysql 的一個表的資料的時候報告如下錯誤：

mysql> delete from upload_images;

ERROR 1175 (HY000): You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column

mysql> show variables like '%sql_safe%';

+------------------+-------+

| Variable_name    | Value |

| sql_safe_updates | ON    |

1 row in set (0.00 sec)

mysql> set sql_safe_updates=0;

Query OK, 0 rows affected (0.00 sec)

| sql_safe_updates | OFF   |

Query OK, 505 rows affected (0.01 sec)

然後再啟用safe mode 

mysql> set sql_safe_updates=1;
