mysql数据库执行delete报错

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.
现象：使用工具Workbench执行sql删除数据库中某些数据时，经常报错如下：
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. To disable safe mode, toggle the option in Preferences -> SQL Editor and reconnect.
原因分析：workbench操作mysql数据库时，使用的是安全更新模式，执行delete时必须要禁用安全模式。
解答方法：办法1：SET SQL_SAFE_UPDATES = 0;
办法2：在where判断条件中跟上主键id（例如ID>=0） 例如：delete from mysqldatabase.user where UserName='name' and ID>=0;
