I have the following SQL script:

DECLARE @temp table (     ID int IDENTITY(1, 1),     data nvarchar(100) )  INSERT INTO @temp (data) VALUES ('a,b,c') INSERT INTO @temp (data) VALUES ('d,e,f')  SELECT * FROM @temp AS T     INNER JOIN         (SELECT *         FROM dbo.__StringSplit(T.data, ',', T.ID)) AS S     ON T.ID = S.RefID

And on after clicking !Execute, I got these:

Line 17 The multi-part identifier 'T.data' could not be bound.

I have also tried the non-join version and got the same error:

SELECT T.ID, S.Item AS dataItem FROM @temp AS T, dbo.__StringSplit(T.data, ',', T.ID) AS S WHERE T.ID = S.RefID

…

What I expected was that I should gets a table with IDs coming from @test.ID and each comma-separated values in @test.data gets split up into its own records and its value put into the dataItem field.

How can I accomplish that?
Am I required to use cursors?

I’ve pasted the dbo.__StringSplit table-valued-function implementation at http://pastebin.com/f7dd6350f

Thanks!

  1. In SQL2000 you need cursors. In SQL2005/2008, you can use CROSS APPLY satement; probably like next (can’t test just now):

    SELECT T.ID, S.Item AS dataItem FROM @temp AS T CROSS APPLY dbo.__StringSplit(T.data, ',', T.ID) AS S

    EDIT – I found this page on CROSS APPLY and then came up with:

    SELECT T.ID, S.Item AS dataItem FROM @temp AS T     CROSS APPLY     dbo.__StringSplit(T.data, ',', T.ID) AS S WHERE T.ID = S.RefID

    Which solved my problem 🙂
