Hi
<code snippet>
select max(f1) as nf1 , max(f2) as nf2, max(f3) as nf3, max(f4) as nf4 from
table

How can I extract a max value from the 4 columns of the result ?
ex: greatest(nf1,nf2,nf3,nf4)
Thanks
SELECT MAX (max(f1) as nf1 , max(f2) as nf2, max(f3) as nf3, max(f4) as
nf4) AS maximum FROM table
Not tested but should work :)
