MySQL 5.7.9版本sql_mode=only_full_group_by問題

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'gambling.team_odds_match.league_name' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

 

 

解決方法 ：執行SET GLOBAL sql_mode = ''; 把sql_mode 改爲非only_full_group_by模式。驗證是否生效 SELECT @@GLOBAL.sql_mode 或 SELECT @@sql_mode

SET GLOBAL  sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
