• Error Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column.


    执行delete-SQL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.    0.00084 sec

    参考文档:

    1. 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。

      异常内容: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 Queries and reconnect.

      Error Code: 1175. You are using safe update
    2.  

      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

      SET SQL_SAFE_UPDATES = 0;
      Error Code: 1175. You are using safe update
    3.  

      为测试命令确实成功执行,我们先看执行update命令前的数据状态

      Error Code: 1175. You are using safe update
    4.  

      执行update命令,可以看出命令执行成功的状态

      Error Code: 1175. You are using safe update
    5.  

      重新查询数据库值,已经成功更新

      Error Code: 1175. You are using safe update
    6.  

      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;

      执行成功后,以delete命令为例,非主键情况下又报错了,说明安全等级修改成功

      Error Code: 1175. You are using safe update
