mysql不支持分组查询非分组数据报错

Expression #4 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'waterenvironment.c.check_river' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by   

select @@global.sql_mode

set @global.sql_mode
='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION'
