MySQL Workbench批量更新或删除

Error Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column To disable safe mode, toggle the option in Preferences -> SQL Queries and reconnect. 0.000 sec

因为是MySQL Workbench的默认的安全设置是不能批量更新表的。

解决方法：

一、在SQL语句之前添加

    SET SQL_SAFE_UPDATES = 0;

二、修改MySQL Workbench设置：

• 打开Workbench的菜单[Edit]->[Preferences...]

• 切换到[SQL Queries]页面（不同版本可能在SQL Editor）

• “Safe Updates”.Forbid UPDATEs and DELETEs with no key in WHERE clause or no LIMIT clause.Requires a reconnection之前的对勾去掉.

• 点击【OK】，重启Workbench.
