我有一个表 dapartment_dup,我想在其中更新一条记录,当我执行查询时它给我一个错误
我的查询是
update department_dup
set dept_name = null
where dept_no = 'd010';
错误是
21:17:21 update department_dup set dept_name = null where dept_no = 'd010' 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. 0.000 sec
在错误消息中,它给了我路径,但我不明白在哪里重新连接?
