Greatest value

Hi all. I'm looking for assistance to get the greatest value from 3 or
more different columns. I'm assuming that the best way is to put the
columns into a temp table and use 'max' function to return the greatest
value but don't know how to code it. Thanks in advance.

Here's an example of what you want using a derived table
declare @t table(id int, val1 int,val2 int,val3 int)
insert into @t(id,val1,val2,val3) values(1,100,200,300)
insert into @t(id,val1,val2,val3) values(2,300,400,500)
insert into @t(id,val1,val2,val3) values(3,600,700,800)

select id,max(vals)
select id,val1
from @t
union all
select id,val2
from @t
union all
select id,val3
from @t
) X(id,vals)
group by id
