I want to pass comma separated values to a parameter variable in sql server.

Currently getting values as

@test='ab','bc','cd'. But when passing this parameter variable in IN clause of where condition it is not working.

What I have tried:

  declare
 @ChannelTypeXml xml,
 @TransactionTypeXml xml
 
 
 SET @ChannelTypeXml='<ROOT><CHANNELTYPE><CHANNEL>FGBO</CHANNEL></CHANNELTYPE>
 <CHANNELTYPE><CHANNEL>IB</CHANNEL></CHANNELTYPE>
 <CHANNELTYPE><CHANNEL>Manual Upload - FGB</CHANNEL></CHANNELTYPE></ROOT>'
 
 
 --select @TransactionTypeXml = FileType                                                                    
 --from   USERS                                                                                                         
 --where
 --UserId= 'bm'
 --and
 --Role='BM'                                                                                      
 --AND  IsDeleted=0  
 
 
 select @ChannelTypeXml
 
declare @ChannelTypeValues varchar(4000)
select @ChannelTypeValues = ''
 
SELECT @ChannelTypeValues = @ChannelTypeValues +  ''''+ t.c.value('CHANNEL[1]','varchar(100)') +'''' + ','
FROM   @ChannelTypeXml.nodes('//ROOT/CHANNELTYPE') T(c)
 
select @ChannelTypeValues = substring(@ChannelTypeValues,1,len(@ChannelTypeValues)-1)
 
select @ChannelTypeValues

Where in the code is using the IN clause?

Ok. This is my assumption based on what being posted here. The current query is returning @ChannelTypeValues = 'FGBO','IB','Manual Upload - FGB'? And the next invisible/secret query will use that variable as a filter? [SELECT * FROM SECRETTable WHERE secretColumn IN @ChannelTypeValues ]???

Here how the query can accomplish the above scenario.

SQL

DECLARE @ChannelTypeXml xml

DECLARE @tempChannelType TABLE (ChannelType VARCHAR(50))
DECLARE @tempDummy TABLE (Column1 VARCHAR(50), ChannelType VARCHAR(50))

 SET @ChannelTypeXml='<ROOT><CHANNELTYPE><CHANNEL>FGBO</CHANNEL></CHANNELTYPE>
 <CHANNELTYPE><CHANNEL>IB</CHANNEL></CHANNELTYPE>
 <CHANNELTYPE><CHANNEL>Manual Upload - FGB</CHANNEL></CHANNELTYPE></ROOT>'

 --dummy table
INSERT INTO @tempDummy
	SELECT 'abcd','FGBO' UNION
	SELECT 'xyz','IB' UNION
	SELECT 'Kitty','CAT' UNION
	SELECT 'hijk','Manual Upload - FGB' UNION
	SELECT 'Woof Woof','DOG';

--get the channel 
INSERT INTO @tempChannelType
	SELECT t.c.value('CHANNEL[1]','varchar(100)') 
	FROM   @ChannelTypeXml.nodes('//ROOT/CHANNELTYPE') T(c)

SELECT * FROM @tempChannelType
SELECT * FROM @tempDummy WHERE ChannelType IN (SELECT * FROM @tempChannelType)

Place the channelvalue extracted from XML into a temporary table

ChannelType
FGBO
IB
Manual Upload - FGB

Apply the filter results

Column1	ChannelType
abcd	FGBO
hijk	Manual Upload - FGB
xyz	    IB
