mysql执行update操作报错:
update psmp.Users set name='Jack' where name='Lily';
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
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。
可以通过以下SQL进行状态查询:
show variables like 'SQL_SAFE_UPDATES';
safe-updates
模式:SET SQL_SAFE_UPDATES = 0;
或
SET SQL_SAFE_UPDATES = false;
safe-updates
模式:SET SQL_SAFE_UPDATES = 1;
或
SET SQL_SAFE_UPDATES = true;
