如何在 sql 查询中获取带日期的整数总和？

Question

我有以下查询，我想添加特定日期的所有视图，如下所示。

SELECT SUM("videoView"."views"), "videoView"."startDate"::timestamp::date
FROM "videoView" 
WHERE "videoView"."videoId" =23 
AND ("videoView"."startDate"::timestamp::date)= '2021/11/25'
GROUP BY "videoView"."startDate"

我想要的结果是：

sum     date
3       2021/11/25

我得到的结果是

sum      date 
2        2021/11/25
1        2021/11/25

Answer 1

select SUM(WordCount) as 'words per day' 
from @WordsCount 
group by DateAdded

Answer 2

如@joachim-isaksson 所述，您可以按以下方式执行此操作：

SELECT SUM("videoView"."views"), "videoView"."startDate"::timestamp::date
FROM "videoView" 
WHERE "videoView"."videoId" =23 
AND ("videoView"."startDate"::timestamp::date)= '2021/11/25'
GROUP BY "videoView"."startDate"::timestamp::date;
