CREATE FUNCTION [dbo].[Udf_split] (@List  VARCHAR(max), @Delim CHAR)

      SET @list = Ltrim(Rtrim(@list)) + @Delim    

      SET @pos = Charindex(@delim, @list, 1)    

   

      WHILE @pos > 0     

        BEGIN    

            SET @list1 = Ltrim(Rtrim(LEFT(@list, @pos - 1)))    

   

            IF @list1 <> ''    

              INSERT INTO @ParsedTable VALUES (Cast(@list1 AS VARCHAR(max)))

            SET @pos = Charindex(@delim, @list, 1)
