在多行上执行表值函数？

Given a table-valued function such as dbo.Split() from "T-SQL: Opposite to string concatenation - how to split string into multiple records", how do I pass multiple rows as arguments?

给定一个表值函数，例如来自“T-SQL：与字符串连接相反 - 如何将字符串拆分成多个记录”的dbo.Split（），如何将多行作为参数传递？

This works:

这有效：

SELECT *
FROM dbo.Split
  (',', (SELECT myColumn FROM Stuff WHERE id = 22268))
WHERE ISNULL(s,'') <> ''

It returns:

它返回：

pn          s
----------- -----------
1           22351
2           22354
3           22356
4           22357
5           22360

But this does not:

但这不是：

SELECT *
FROM dbo.Split
  (',', (SELECT myColumn FROM Stuff))
WHERE ISNULL(s,'') <> ''

Nor does this:

这也不是：

SELECT * FROM dbo.Split_temp(',', myColumn), Stuff

The docs say:

文档说：

When a user-defined function that returns a table is invoked in the FROM clause of a subquery, the function arguments cannot reference any columns from the outer query.

当在子查询的FROM子句中调用返回表的用户定义函数时，函数参数不能引用外部查询中的任何列。

The sort of result set I'm looking for would look something like:

我正在寻找的那种结果集看起来像：

id          pn          s
----------- ----------- -----------
22268       1           22351
22268       2           22354
22268       3           22356
22268       4           22357
22268       5           22360
24104       1           22353
24104       2           22355
24104       3           22356
24104       4           22358
24104       5           22360
24104       6           22362
24104       7           22364
.
.
.

Is there any way at all (aside from, of course, a cursor) to accomplish this?

有没有办法（除了光标之外）完成这个任务？

As requested by MarlonRibunal, a sample table to produce the above result looks like:

根据MarlonRibunal的要求，产生上述结果的样本表如下所示：

id          myColumn
----------- -------------------------------------------
22268       22351,22354,22356,22357,22360,
24104       22353,22355,22356,22358,22360,22362,22364,

id is an int; myColumn is a varchar(max).

id是一个int; myColumn是varchar（max）。

2 个解决方案

#1

OUTER APPLY:

外部申请：

SELECT Stuff.id
    ,Results.pn
    ,Results.s
FROM *_454945 AS Stuff
OUTER APPLY dbo.Split(',', Stuff.myColumn) AS Results
WHERE ISNULL(Results.s,'') <> ''

#2

You could use the COALESCE concatenation behavior

您可以使用COALESCE并置行为

declare @split varchar(max) 
set @split = ''

select @split = @split + Coalesce(myColumn + ',' , ' ') 
from Stuff 
WHERE id = 22268

select * from dbo.Split(',', @Left(@split,len(@split) -1))

I don't know that that would be any better than using a cursor.

我不知道那会比使用游标更好。
