Answer 1

You need to use a UDF for splitting it on each row

CREATE FUNCTION [DBO].[FN_SPLIT_STR_TO_COL] (@T AS VARCHAR(4000) )
RETURNS
 @RESULT TABLE(VALUE VARCHAR(250))
AS
BEGIN
     SET @T= @T+';'
       ;WITH MYCTE(START,[END]) AS(

    SELECT 1 AS START,CHARINDEX(';',@T,1) AS [END]
    UNION ALL
    SELECT [END]+1 AS START,CHARINDEX(';',@T,[END]+1)AS [END] 
    FROM MYCTE WHERE [END]

Now query on your table by calling above function with CROSS APPLY

  SELECT [CodeCombination],FN_RS.VALUE FROM TABLE1
  CROSS APPLY
 (SELECT * FROM [DBO].[FN_SPLIT_STR_TO_COL] (User))           
  AS FN_RS
