SQL更新语句,Error Code: 1175. You are using safe update(在进行视图更新的时候遇到)
转发于:http://blog.csdn.net/qq_26684469/article/details/51105188?locationNum=5&fps=1
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
***************20171206更新************************ 一劳永逸方法
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。
