mysql you are using safe update mode

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.

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。

1、show variables like 'SQL_SAFE_UPDATES';查看开关状态。

2、执行命令SET SQL_SAFE_UPDATES = 0;修改下数据库模式
