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。。

This is because MySql running in safe-updates mode, which can lead to non-primary key condition unable to perform update or delete command.

 

1, show variables like 'SQL_SAFE_UPDATES'; see switching state.

 

2, Run SET SQL_SAFE_UPDATES = 0; modify the database schema
