MySQL关闭安全模式

MySQL运行在safe-update模式下时，非主键条件下是无法执行update或者delete命令的

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.

查看安全模式开关，能够发现当前是启用状态

show variables like 'SQL_SAFE_UPDATES';

直接将其关闭即可

SET SQL_SAFE_UPDATES = 0;

关闭后便可以正常执行update和delete命令了

delete from t_p_test ;
