SELECT list is not in GROUP BY clause and contains nonaggregated
作者:互联网
一、错误
> 1055 - Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'n.wifi_mac' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
二、查询
SELECT @@sql_mode; 结果 ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
三、修改/etc/my.cnf文件,添加sql_model(把ONLY_FULL_GROUP_BY删掉)
SELECT @@sql_mode; 结果 ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
