You will have to handle it yourself, there is no built in mechanism for that. But it's not that complex: Using comma separated value parameter strings in SQL IN clauses[^] shows a function designed to handle a single CSV string, you could easily adapt it to do two.

Create this function that will used for parse values

SQL

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[ParseValues]
(@String varchar(8000), @Delimiter varchar(max) )
RETURNS @RESULTS TABLE (ID int identity(1,1), Val varchar(max))
AS
BEGIN
    DECLARE @Value varchar(max)
    WHILE @String is not null
    BEGIN
        SELECT @Value=CASE WHEN PATINDEX('%'+@Delimiter+'%',@String) >0 THEN LEFT(
          @String,PATINDEX('%'+@Delimiter+'%',@String)-1) ELSE @String END, 
          @String=CASE WHEN PATINDEX('%'+@Delimiter+'%',@String) >0 THEN SUBSTRING(
          @String,PATINDEX('%'+@Delimiter+'%',@String)+LEN(@Delimiter),LEN(@String)) ELSE NULL END
        INSERT INTO @RESULTS (Val)
        SELECT @Value
    END
RETURN
END

Query to use...

SQL

select a.val as Alpha ,b.val as Nums from dbo.parsevalues('a,b,c,d',',')  as a
left join dbo.parsevalues('1,2,3,4',',')  as b on a.id=b.id

Happy Coding!
