Greetings,
Version: PostgreSQL 8.0.13 on i686-pc-linux-gnu
I have a table test(col1, col2, col3)
For each row, I'd like to get the "max"(col1, col2, col3).
For example, test(1, 5, 2)
test(8, 1, 3)
test(12, 1, 1)
select ?max?(col1, col2, col3) as result;
will return
result
-------
5
8
12
(3 rows)
Thanks!
Ly.
