     CASE WHEN SUBSTRING(Result+ SPACE(5),1,1) = 'P' THEN 'Pass'
          WHEN ISNUMERIC(SUBSTRING(Result+ SPACE(5),1,1)) = 1 THEN 'Fail'
          ELSE 'Invalid' END AS Result
FROM table1
UNION ALL 
SELECT RegisterNo,'Sanskrit' AS Subject ,
     CASE WHEN SUBSTRING(Result+ SPACE(5),3,1) = 'P' THEN 'Pass'
