数据库如下：

我想要得到的输出是：

我的sql查询是这样的，得到的输出是这样的。

SELECT score as "0-25" , COUNT(*) FROM Gamer WHERE (score > 0 and score<25)
UNION 
SELECT score as "26-50", COUNT(*) FROM Gamer WHERE (score > 26 and score<50)
UNION 
SELECT score as "51-75", COUNT(*) FROM Gamer WHERE (score > 51 and score<75)
UNION 
SELECT score as "76-100", COUNT(*) FROM Gamer WHERE (score > 76 and score<=100)

您有问题吗？

标签： sql sqlite count pivot

【解决方案1】：

您使用条件聚合。在 SQLite 中：

select 
    sum(score between  0 and  25) as s_00_25,
    sum(score between 26 and  50) as s_26_50,
    sum(score between 51 and  75) as s_51_75,
    sum(score between 76 and 100) as s_76_100
from gamer
