Question

我有一张名为＆＃34的表格;结果＆＃34;如下所示：

我想计算完全得分的人员。这意味着得分列中没有零的人。例如，基于上传的图片，只计算ID为1004的人，结果应为1。 我用了这段代码：

select Count(PrsID) from results 
where Score <> 0
group by PrsID

但如果一个人只有一个非零分数，它就不会帮助我，他将被计算在内！

提前致谢。

Answer 1

我想你想要这样的东西：

select PrsID, Count(1) from results 
where Score = 0
group by PrsID

Answer 2

这个返回非零分数的人数

SELECT 
    t1.PrsID,
    Count(t1.PrsID)
FROM
(   SELECT 
      * 
    FROM results 
    GROUP BY results.PrsID
    ORDER BY results.Score ASC
) AS t1
WHERE t1.Score <> 0;

Answer 3

您可以使用以下条件聚合：

Select PrsId from results
    group by PrsId
    having sum(case when score = 0 then 1 else 0 end) > 1

Answer 4

如果我理解正确，我认为这就是你想要的：SELECT COUNT(DISTINCT(PrsID)) FROM results WHERE PrsID NOT IN (SELECT DISTINCT PrsID FROM results WHERE score = 0)

Answer 5

如果一个人的最低分数大于零，则应计算它们。

select count(1)
from (
        select PrsID 
        from results 
        group by PrsID
        having min(Score) > 0) as results
