Question

I have a table Kwd_UploadRecored in SQL Server:
ID Primary_Kwd Sec_Kwd Main_Kwd
1 Man,One Man,architecture,Boy Arrival,Sigle Man , Business Man ,Male aspirations,One Person
2 Woman,attire,Girl Girl,Girls,Female,Blueprint,Carrying, Teenage Girl,Only Girls

Kwds
man
one man
architecture
boy
arrival
Single man
Business man
Male
.
.
etc
I am using the following code but this is only for one column
SELECT DISTINCT
Split.a.value('.', 'VARCHAR(100)') data
FROM
(SELECT
#temp.PM_AssetID,Cast ('<M>'
+ replace(Replace(#temp.Primary_kwd, ',', '</M><M>'),'&','&')
+ '</M>' AS XML) AS Data
FROM #temp) AS A
CROSS APPLY
Data.nodes ('/M') AS Split(a)
DROP TABLE #temp
Please help me how to achieve this. Thanks in advance.

Answer 1

You can use UNION to remove duplicates:
;WITH CtePrimary AS(
SELECT
LTRIM(RTRIM(s.Item)) AS Item
FROM Kwd_UploadRecorded k
CROSS APPLY dbo.DelimitedSplit8K(k.Primary_Kwd, ",") s
),
CteSec AS(
SELECT
LTRIM(RTRIM(s.Item)) AS Item
FROM Kwd_UploadRecorded k
CROSS APPLY dbo.DelimitedSplit8K(k.Sec_Kwd, ",") s
),
CteMain AS(
SELECT
LTRIM(RTRIM(s.Item)) AS Item
FROM Kwd_UploadRecorded k
CROSS APPLY dbo.DelimitedSplit8K(k.Main_Kwd, ",") s
)
SELECT * FROM CtePrimary UNION
SELECT * FROM CteSec UNION
SELECT * FROM CteMain
As per Turophile's comment, you can rid of the UNION by concatenating the kwds first before splitting them.
SELECT DISTINCT
LTRIM(RTRIM(s.Item)) AS Item
FROM Kwd_UploadRecorded k
CROSS APPLY dbo.DelimitedSplit8K(k.kPrimary_kwd + ',' + k.Sec_kwd + ',' + k.Main_kwd, ",") s

Answer 2

Can you try this
Select *
from #temp
cross apply fnSplit(Primary_Kwd,',')a
where a.value > ''
union all
Select b.value
from #temp
cross apply fnSplit(Sec_Kwd,',')b
where b.value > ''
union all
Select c.value
from #temp
cross apply fnSplit(Main_Kwd,',')c
where c.Value > ''

You have to Create a Spit function and use Cross Aplly
Main Query
SELECT Distinct T.ID
,S.Data
FROM Kwd_UploadRecored AS T
CROSS APPLY dbo.Split(isnull(T.Primary_Kwd+ ',','') + isnull(Sec_Kwd+',','') + ',' + isnull(Main_Kwd+',' ,'') ) AS S
WHERE S.Value > ''
Split Function Code
CREATE FUNCTION [dbo].[Split]
(
#RowData nvarchar(MAX),
#SplitOn nvarchar(5)
)
RETURNS #RtnValue table
(
Id int identity(1,1),
Data varchar(8000)
)
AS
BEGIN
Declare #Cnt int
Set #Cnt = 1
While (Charindex(#SplitOn,#RowData)>0)
Begin
Insert Into #RtnValue (data)
Select
Data = ltrim(rtrim(Substring(#RowData,1,Charindex(#SplitOn,#RowData)-1)))
Set #RowData = Substring(#RowData,Charindex(#SplitOn,#RowData)+1,len(#RowData))
Set #Cnt = #Cnt + 1
End
Insert Into #RtnValue (data)
Select Data = ltrim(rtrim(#RowData))
Return
END
