If you're trying to just get the rows that have the max date for each code, you might want to try:

select code, name, date from table a
where date=(select max(date) from table b
           where a.code = b.code)

BTW, that's not a typo.  It's a double reference to the same table.

Let us know if you're looking for something else.   :)
