Hello,
I am trying to create a mapper table out of the existing table which has a CSV delimited column.
I am trying to use DelimitedSplit8K iTVF. I am running this on SQL 2008 and getting the following error.
Here is the function definition for DelimitedSplit8K:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION dbo.DelimitedSplit8K
--===== Define I/O parameters
(@pString VARCHAR(8000), @pDelimiter CHAR(1))
RETURNS TABLE WITH SCHEMABINDING AS
RETURN
--===== "Inline" CTE Driven "Tally Table" produces values from 0 up to 10,000...
-- enough to cover VARCHAR(8000)
WITH E1(N) AS (
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1
), --10E+1 or 10 rows
E2(N) AS (SELECT 1 FROM E1 a, E1 b), --10E+2 or 100 rows
E4(N) AS (SELECT 1 FROM E2 a, E2 b), --10E+4 or 10,000 rows max
cteTally(N) AS (--==== This provides the "zero base" and limits the number of rows right up front
-- for both a performance gain and prevention of accidental "overruns"
SELECT 0 UNION ALL
SELECT TOP (DATALENGTH(ISNULL(@pString,1))) ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM E4
),
cteStart(N1) AS (--==== This returns N+1 (starting position of each "element" just once for each delimiter)
SELECT t.N+1
FROM cteTally t
WHERE (SUBSTRING(@pString,t.N,1) = @pDelimiter OR t.N = 0)
)
--===== Do the actual split. The ISNULL/NULLIF combo handles the length for the final element when no delimiter is found.
SELECT ItemNumber = ROW_NUMBER() OVER(ORDER BY s.N1),
Item = SUBSTRING(@pString,s.N1,ISNULL(NULLIF(CHARINDEX(@pDelimiter,@pString,s.N1),0)-s.N1,8000))
FROM cteStart s
;
Here is my test case:
CREATE TABLE #List (List varchar(100))
INSERT INTO #List VALUES ('AB,CD,EF,GH,IJ,KL,MN,OP,QR,ST,UV,WZ,YZ')
Table has been created and populated with data
select * from #List
List
-----------------------------------------
AB,CD,EF,GH,IJ,KL,MN,OP,QR,ST,UV,WZ,YZ
Verified that the data is selected
select f.*
FROM #List l
CROSS APPLY DelimitedSplit8K(l.List, ',') f
Msg 102, Level 15, State 1, Line 3
Incorrect syntax near '.'.
I get the above error message..... I tried with different test data...It wouldn't work....
See below:
select f.*
FROM #List l
CROSS APPLY DelimitedSplit8K('AB,CD,EF,GH,IJ,KL,MN,OP,QR,ST,UV,WZ,YZ', ',') f
Above query return the result fine...
1AB
2CD
3EF
4GH
5IJ
6KL
7MN
8OP
9QR
10ST
11UV
12WZ
13YZ
not sure what is going wrong when I pass the CSV Delimited column name.
Please advise

Same experience - works fine for me. I would check compat level and service packs.
