sql在数据库里正常执行，
但是用nutz执行时，接不到primary_pollutant，想问一下这块怎么接

select
				area_code,GROUP_CONCAT(primary_pollutant separator '') as 'primary_pollutant'
				from base_air_quality_live
				where
				    data_date_time like '2018-08-09%' and
				    area_code in (select  value from sys_dict where  type = 'key_citys_nmg')
				group by area_code
