在sql中获取查询外部的变量
我知道我的标题有点误导,但我不确定什么是好标题 Authored有两列,即ID、PubID 无论如何,我都可以将p输出到结果中 我想知道,对于每个各自的ID,PubID对,有多少行具有相同的PubID但不同的ID在sql中获取查询外部的变量,sql,Sql,我知道我的标题有点误导,但我不确定什么是好标题 Authored有两列,即ID、PubID 无论如何,我都可以将p输出到结果中 我想知道,对于每个各自的ID,PubID对,有多少行具有相同的PubID但不同的ID select a.authorId, P from Authored A WHERE 1 < (Select count(*) as P from Authored B where A.pubId = B.pubId AND A.authorId<> B.au

预期结果
请尝试以下MS Sql server查询:
select
*,
COUNT(*) over (partition by pubId)
From Authored
where authorId<>pubId
选择
*,
计数(*)超过(按pubId划分)
来自作者
作者ubid在哪里
使用count()over()更新:
:
select a.AuthorId, count(*) over(partition by pubId) counts
from Authored a
order by a.AuthorId;
这就是你的意思吗?不清楚你在问什么
你能展示一些数据和预期结果吗?
select
*,
COUNT(*) over (partition by pubId)
From Authored
where authorId<>pubId
select a.AuthorId, count(*) over(partition by pubId) counts
from Authored a
order by a.AuthorId;
select
count(ID) P,
PubID
from
(select distinct ID, pubID from Authored) d
group by
PubID
This will give you the number of distinct `ID/authorId` for each `PubID\pubId`
