問題描述

select age,money from t1.gz group by age;發現報錯：Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column ’t1.gz.money’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

問題解答

你現在的sql_mode不允許有非聚合字段以非聚合函數的形式出現，改一下sql_mode即可，或者min(id)取第一行記錄再連接原表獲取你要的結果
