Split sql parameter on comma

Question

Below code works for \'Main Stream\' or \'Premium\' as parameter, however I am trying to make it work for both of them as you can see below, but it doesn\'t return any resul

I found a nice solution for a similar issue on another thread on SO.
Basically, it uses a function for splitting a string (@MyParameter in your case) using a delimiter (',' in your case).

Here is how you call the function:

declare @myParameter varchar(50)
SET @myParameter = 'Main Stream,Premium'

--this table will hold delimited values
DECLARE @ParsedTable TABLE 
(   
        [id] [int] NOT NULL,
        [content] [nvarchar](50) NULL
)
    --Parsing @myParameter
INSERT INTO @ParsedTable
SELECT * from [dbo].[SplitString](@myParameter, ',')
--SELECT * FROM @ParsedTable --This will show you the values... 
--run the query 
select * FROM sales  
where myCategory IN (SELECT content from @ParsedTable)

And here is the code for creating the split functions:

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[SplitString]') AND type in (N'FN', N'IF', N'TF', N'FS', N'FT'))
DROP FUNCTION [dbo].[SplitString]
go

/****** Object:  UserDefinedFunction [dbo].[SplitString]    Script Date: 11/04/2013 19:04:05 ******/
SET ANSI_NULLS ON
go

SET QUOTED_IDENTIFIER ON
go

CREATE FUNCTION [dbo].[SplitString] 
(
    -- Add the parameters for the function here
    @StringToDelimit nvarchar(500),
    @deliminator nvarchar(2)
)
RETURNS 
@ReturnTable TABLE 
(
    -- Add the column definitions for the TABLE variable here
    [id] [int] IDENTITY(1,1) NOT NULL,
    [content] [nvarchar](50) NULL
)
AS
BEGIN
        Declare @delimitorIdx int
        Declare @content varchar(50)

        --initialize spaces
        Select @delimitorIdx = charindex(@deliminator,@StringToDelimit,0)
        While @delimitorIdx > 0

        Begin
            Select @content = substring(@StringToDelimit,0,charindex(@deliminator,@StringToDelimit,0))

            Insert Into @ReturnTable(content)
            Select @content

            Select @StringToDelimit = substring(@StringToDelimit,charindex(@deliminator,@StringToDelimit,0)+ 1,len(@StringToDelimit) - charindex(' ',@StringToDelimit,0))

            Select @delimitorIdx = charindex(@deliminator,@StringToDelimit,0)
        end

        If len(@StringToDelimit) > 0
            Insert Into @ReturnTable
            Select @StringToDelimit

    RETURN 
END
