Hi Guys,
I have one task to derived column values by splitting the string by hypens
below is the DDL,
CREATE TABLE #TABLE
(COL VARCHAR (100) )
INSERT INTO #TABLE VALUES ('Sam Capali - Test1 - 12526 - 1 - Period 2')
INSERT INTO #TABLE VALUES ('Mike M Capela')
INSERT INTO #TABLE VALUES ('Natalie Simon - Test1/Test2/Test3 Gr 5 - 25143 - 3 - Period 3')
INSERT INTO #TABLE VALUES ('James Germeny - Test1 & Test2 Ed - 62549 - 2 - Period 2')
desired output is,
column1 column2 column3 column4 column5
Sam Capali Test1 12526 1 Period 2
Mike M Capela
Natalie Simon Test1/Test2/Test3 Gr 5 25143 3 Period 3
James Germeny Test1 & Test2 Ed 62549 2 Period 2
Please help me to build this, Thanks for your help in advance.
Looking forward for any inputs from you guys.
Thanks

This will split the data:SELECT col, ds.ItemNumber, ds.Item
FROM #Table t
CROSS APPLY Utilities.dbo.DelimitedSplit8K(col,'-') ds
Then you would have to pivot it. This is most of the way there:SELECT x.col
, MAX(x.col1) AS c1
, MAX(x.col2) AS c2
, MAX(x.col3) AS c3
, MAX(x.col4) AS c4
, MAX(x.col5) AS c5
FROM
(SELECT col
, item
, itemNumber
, case when itemNumber = 1 then Item else NULL end AS col1
, case when itemNumber = 2 then Item else NULL end AS col2
, case when itemNumber = 3 then Item else NULL end AS col3
, case when itemNumber = 4 then Item else NULL end AS col4
, case when itemNumber = 5 then Item else NULL end AS col5
FROM #Table t
CROSS APPLY Utilities.dbo.DelimitedSplit8K(col,'-') ds) x
GROUP BY x.col

Check the function from this article
😎
The function (slightly modified)
CREATE FUNCTION [dbo].[DelimitedSplit8K_LEAD]
--===== 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 T(N) AS (SELECT X.N FROM (VALUES (0),(0),(0),(0),(0),(0),(0),(0),(0),(0)) X(N))
, NUMS(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 T T1,T T2,T T3,T T4
),
cteStart(N1) AS (--==== This returns N+1 (starting position of each "element" just once for each delimiter)
SELECT t.N+1
FROM NUMS 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((LEAD(s.N1,1,1) OVER (ORDER BY s.N1) - 1),0)-s.N1,8000))
FROM cteStart s
;
The application code
USE TEEST;
GO
SET NOCOUNT ON;
DECLARE @TABLE TABLE
(COL VARCHAR (100) )
INSERT INTO @TABLE VALUES
('Sam Capali - Test1 - 12526 - 1 - Period 2')
, ('Mike M Capela')
, ('Natalie Simon - Test1/Test2/Test3 Gr 5 - 25143 - 3 - Period 3')
, ('James Germeny - Test1 & Test2 Ed - 62549 - 2 - Period 2')
;
;WITH BASE_DATA(COL_ID,COL) AS
(
SELECT
ROW_NUMBER() OVER
(
PARTITION BY @@VERSION
ORDER BY @@VERSION
) AS COL_ID
,T.COL
FROM @TABLE T
)
SELECT
BD.COL_ID
,MAX(CASE WHEN X.ItemNumber = 1 THEN LTRIM(RTRIM(X.Item)) END) AS COL_01
,MAX(CASE WHEN X.ItemNumber = 2 THEN LTRIM(RTRIM(X.Item)) END) AS COL_02
,MAX(CASE WHEN X.ItemNumber = 3 THEN LTRIM(RTRIM(X.Item)) END) AS COL_03
,MAX(CASE WHEN X.ItemNumber = 4 THEN LTRIM(RTRIM(X.Item)) END) AS COL_04
,MAX(CASE WHEN X.ItemNumber = 5 THEN LTRIM(RTRIM(X.Item)) END) AS COL_05
,MAX(CASE WHEN X.ItemNumber = 6 THEN LTRIM(RTRIM(X.Item)) END) AS COL_06
,MAX(CASE WHEN X.ItemNumber = 7 THEN LTRIM(RTRIM(X.Item)) END) AS COL_07
,MAX(CASE WHEN X.ItemNumber = 8 THEN LTRIM(RTRIM(X.Item)) END) AS COL_08
FROM BASE_DATA BD
CROSS APPLY dbo.DelimitedSplit8K_LEAD(BD.COL,CHAR(45)) X
GROUP BY BD.COL_ID
ORDER BY BD.COL_ID ASC;
And the output
COL_ID COL_01 COL_02 COL_03 COL_04 COL_05 COL_06 COL_07 COL_08
------- --------------- ----------------------- ------- ------- --------- ------- ------- -------
1 Sam Capali Test1 12526 1 Period 2 NULL NULL NULL

Thanks,
It works as i need it.
Thanks for your help.
