快速高效用：SET SQL_SAFE_UPDATES = 0；下面的就不要看了！
今日用MySQL Workbench进行数据库的管理更新时，执行一个更新的语句碰到以下错误提示：
Error Code: 1175
You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column
进过一番搜索之后发现原来是MySQL Workbench的安全设置。当要执行的SQL语句是进行批量更新或者删除的时候就会提示这个错误。
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
- 最后一步记得要重启一下Workbench，否则你仍然会得到这个错误提示。
