I guess, you can achieve by the below way,
SELECTCASE IsNull(COL1,'') WHEN '' THEN 'Is Null'
WHEN '0' THEN 'Is Zero'
WHEN '1' THEN 'Is One'
WHEN '2' THEN 'Is Two'
END
FROM
(
SELECT NULL AS Col1
UNION
SELECT '0' AS Col1
UNION
SELECT '1' AS Col1
UNION
SELECT '2' AS Col1
) TMP
This works except you can't differentiate between null and empty strings because your isnull will now treat them both the same. In some cases this is ok but in others it isn't.
