match error:Error 1055: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘appstore_wps_cn.app_stores.app_type’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by”

如何解决？

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';
