Function in SQL Server 2008 similar to GREATEST in mysql?

Question

I want to find the maximum value of multiple columns.

MySQL supports the GREATEST function but SQL Server doesn\'t.

Is there any function similar to this in

Answer 1

For this, I created a scalar function as follows:

CREATE FUNCTION [dbo].[MaxOrNull](@val1 int, @val2 int)
returns int
as
begin
    if @val1 >= @val2 RETURN @val1
    if @val1 < @val2 RETURN @val2

    RETURN NULL
end

It's the most elegant solution and can be used anywhere in your SQL code.
