Example of its use:
select
a.item_number,
b.group_code_description
from
items a,
group_codes b
where
a.group_code = b.group_code (+);
in this example all the records in table "items" appear in the output and
all those records in "group codes" that matches the group_code in items. The
"group_code_description" of all those non-matching records in "group_codes"
table are displayed as NULL.
