MySQL错误:You are using safe update mode and you tried to update a table without a WHERE that uses a K

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。
