sql查询计算agroup计数的总和

Question

字段 id，party，votes

我的查询得到像这样的o / p

 partyname    bjp      aap         congress   

  votes        1        2              2    

但我也需要总票数。以下是我的预期产量。

  BJP         aap           congress       total

   1             2            2             5

SELECT RES.PARTYNAME, COUNT( RES.CONSTITUENCY )
        AS VOTESCOUNT FROM voter_count RES JOIN (SELECT CONSTITUENCY, MAX( VOTES )
        AS VOTES FROM voter_count GROUP BY CONSTITUENCY)MAXS USING ( VOTES, CONSTITUENCY )
        GROUP BY PARTYNAME LIMIT 0 , 1000";

Answer 1

看看这个

SELECT SUM（something）AS something，SUM（else）AS else FROM stuff

只是想知道如何获得SUM

Answer 2

根据你的表格，

SELECT SUM(partyname) AS total_parties, SUM(votes) AS total_votes FROM table_name;

这是你想要的吗？你的问题不明确＆amp;查询与描述无关......
