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?
This works:
SELECT *
FROM dbo.Split
(',', (SELECT myColumn FROM Stuff WHERE id = 22268))
WHERE ISNULL(s,'') <> ''
It returns:
pn s
----------- -----------
1 22351
2 22354
3 22356
4 22357
5 22360
But this does not:
SELECT *
FROM dbo.Split
(',', (SELECT myColumn FROM Stuff))
WHERE ISNULL(s,'') <> ''
Nor does this:
SELECT * FROM dbo.Split_temp(',', myColumn), Stuff
The docs say:
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.
The sort of result set I'm looking for would look something like:
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?
(edit)
As requested by MarlonRibunal, a sample table to produce the above result looks like:
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)
.
OUTER APPLY
:
SELECT Stuff.id
,Results.pn
,Results.s
FROM stackoverflow_454945 AS Stuff
OUTER APPLY dbo.Split(',', Stuff.myColumn) AS Results
WHERE ISNULL(Results.s,'') <> ''
