I tried with SQL below to combine the empid with Active which as when I combine both column MTHID show me different results.

SELECT CASE
            WHEN len(month([Active])) =1  
               THEN empid+ concat(year([Active]),'0',month([Active]))
               ELSE concat(year([Active]),month([Active]))
       END as MonthID, *
FROM MY_CATW

MTHID           EMPID
20212341      20010940
20212341      20010940


With below SQL which I did not combine it appears correctly, so I expect when we combine both column it should have result like 20010940201401

SELECT CASE
            WHEN len(month([Active])) =1  
               THEN   concat(year([Active]),'0',month([Active]))
               ELSE concat(year([Active]),month([Active]))
       END as MonthID, *
FROM MY_CATW

MTHID   EMPID
201401      20010940
201401      20010940
