mysql update时报错You are using safe update mode

在使用mysql执行update的时候,如果不是用主键当where语句,会报如下错误,使用主键用于where语句中正常。

update test.t_bids set product_id=1+floor(rand()*7) 

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. 0.000 sec

这是因为MySql运行在safe-updates模式下,该模式会导致非主键条件下无法执行update或者delete命令,

执行命令SET SQL_SAFE_UPDATES = 0;修改下数据库模式

如果想要提高数据库安全等级,可以在恢复回原有的设置,执行命令:

SET SQL_SAFE_UPDATES = 1;
