Answer 1

Do you need to use a comma separated list? The last couple of years, I've been taking this type of idea and passing in an XML file. The openxml "function" takes a string and makes it like xml and then if you create a temp table with the data, it is queryable.

DECLARE @idoc int
DECLARE @doc varchar(1000)
SET @doc ='


   
      
      
   


   
      
   

'
--Create an internal representation of the XML document.
EXEC sp_xml_preparedocument @idoc OUTPUT, @doc
-- Execute a SELECT statement that uses the OPENXML rowset provider.
SELECT    *
FROM       OPENXML (@idoc, '/ROOT/Customer',1)
            WITH (CustomerID  varchar(10),
                  ContactName varchar(20))
