这三个字段，通过各个函数结果
concat_ws
用相应符号将各字段连接起来 string类型
select concat_ws(',',user_id,mobile,system) as concatfrom statistic.qz_tracklimit 5;concat"13742988,,android""38643821,+8613075351265,android""11230781,,android""38702379,,android""0,+8613414655611,android"spilt
将上述结果通过spilt ， 分开
select split(concat_ws(",",user_id,mobile,system), ",") con_spfrom statistic.qz_tracklimit 5;con_sp"[""13742988"","""",""android""]""[""38643821"",""+8613075351265"",""android""]""[""11230781"","""",""android""]""[""38702379"","""",""android""]""[""0"",""+8613414655611"",""android""]"sort_array 默认升序
select sort_array(split(concat_ws(",",user_id,mobile,system), ",")) as con_safrom statistic.qz_tracklimit 5;con_sa"["""",""13742988"",""android""]""[""+8613075351265"",""38643821"",""android""]""["""",""11230781"",""android""]""["""",""38702379"",""android""]""[""+8613414655611"",""0"",""android""]"
