Solution 1

You can do this using CASE (Transact-SQL)[^].
Here is a sample

SQL

DECLARE @T TABLE
(
	ID VARCHAR(10),
	C1 INT,
	C2 INT,
	C3 INT
)
INSERT INTO @T
SELECT 'T1', 1, 3 , 5 UNION ALL
SELECT 'T2', 5, 1, 10 UNION ALL
SELECT 'T3', 8, 15, 2

SELECT *, CASE WHEN C1 > C2 AND C1 > C3 THEN C1
			WHEN C2 > C1 AND C2 > C3 THEN C2
			ELSE C3 END AS [Result(Max)]
FROM @T

The query I wrote in my solution is just a sample. You can refer it and build your own query.
