Another way to parse CSV parameters for values not necessarily in a table

-- http://www.projectdmx.com/tsql/tblnumbers.aspx
CREATE TABLE dbo.Nbrs(n INT NOT NULL IDENTITY) ;
INSERT dbo.Nbrs DEFAULT VALUES ;
WHILE SCOPE_IDENTITY() < 500 INSERT dbo.Nbrs DEFAULT VALUES ;

DECLARE @p VARCHAR(50)
SET @p = 'ALFKI,LILAS,PERIC,HUNGC,SAVEA,SPLIR,LONEP,GROSR'

SELECT SUBSTRING( ',' + @p + ',', n + 1, CHARINDEX( ',', ',' + @p + ',', n + 1 ) - n - 1 ) AS "value"
FROM Nbrs
WHERE SUBSTRING( ',' + @p + ',', n, 1 ) = ',' AND n < LEN( ',' + @p + ',' ) ;

drop table Nbrs
