Check for GREATEST() and LEAST() functions in ORACLE.
For example, check the following.
SQL> select greatest(10,20) from dual;
GREATEST(10,20)
---------------
20
SQL> select least(10,20) from dual;
LEAST(10,20)
------------
10
SQL>
Hope this helps. Good luck :)

Not pretty but...
for r in (select * from t) loop
v_least := least(r.col1, r.col2, ..., r.col100);
v_greatest := greatest(r.col1, r.col2, ..., r.col100);
end loop; |
