原来的SET SQL_SAFE_UPDATES = 1;

如果条件定语从句where后面跟的不是主键,则会报上面的错,将上面的安全级别设低一点即可,如下:

SET SQL_SAFE_UPDATES = 0;

再执行更新语句,如

SET SQL_SAFE_UPDATES = 0;
update project.demand set title="硬盘到了,谁来帮我换个硬盘啊"
where title="亲热";

删除null值

delete from comment where c_content is null

解决方法如下:

    • 打开Workbench的菜单[Edit]->[Preferences...]
    • 切换到[SQL Editor]页面
    • 把[Forbid UPDATE and DELETE statements without a WHERE clause (safe updates)]之前的对勾去掉
    • 点击[OK]按钮
    • 最后记得要重启一下sql editor,建立一个新的连接就可以了。
