Mysql 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

今天用mysql workbench在更新数据的时候，出现了下面错误：
15:52:39    update wp_posts set post_content = replace(post_content, '/water', '')    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 Editor and reconnect.    0.000 sec
解决办法：在更新之前加上下面这句即可。
SET SQL_SAFE_UPDATES = 0;

或者按照提示在打开菜单的Edit->Preferences，

在重启mysql就行。
