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.
 

出现这个错误，是因为你在做修改或者删除操作的时候，

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;

修改下数据库模式即可。
