執行

select * from user_activity WHERE `status`=1 group by user_id,activity_id having count(*) > 1; 

 

出現：

ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'live.user_gift.u_g_id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

 


解決辦法:

執行
set sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';


去掉ONLY_FULL_GROUP_BY即可正常執行sql.
