Is there a Max function in SQL Server that takes two values like Math.Max in .NET?

In Excel, there’s a function called “MAX” that accepts numbers and returns the largest one in the set. Is there a function in T-SQL that duplicates this functionality? I haven’t been able to find one, and I’ve written a UDF that does it for me, but I thought it was worth asking.

Here is the function I’ve been using:

CREATE FUNCTION dbo.LargerOf
(
    -- Add the parameters for the function here
    @First FLOAT,
    @Second FLOAT
)
RETURNS FLOAT
AS
BEGIN

    DECLARE @Result FLOAT

    IF @First > @Second
        SET @result = @First
    ELSE
        SET @Result = @Second

    RETURN @Result

END
GO

I don’t expect any luck, but instead of moving my function to a whole bunch of new servers, I thought I’d at least ask. Thanks!

I don’t know if the function you need exists, but for a workaround, I like this one better

set @max = case when @first > @second then @first else @second end
