MySQL-Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggre

Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'a_id' which is not functionally

dependent on columns in GROUP BY clause;this is incompatible with sql_mode=only_full_group_by

解決方案

• 先使用 SQL 查詢

select @@global.sql_mode
           

• 此時去掉ONLY_FULL_GROUP_BY，然後重新設定值（引号中填寫裁剪後的字元串）

set @@global.sql_mode='';
           

查出來的值如下

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
