Ansi outer join question

Question

I am on Oracle 10g.
I believe the following two statements are equivalent.
This statement returns the correct results
select k.key, NVL(v.value, k.en_value) as lvalue
from sku_key k, sku_key_value v
WHERE k.id_sku_key = v.id_sku_key (+)
and k.id_sku_key = 5
and v.id_sku_language (+) = 33;
This statement returns no results (however, if I remove the line "and v.id_sku_language = 33" then results are returned, just not the correct results).
select k.key, NVL(v.value, k.en_value) as lvalue
from sku_key k LEFT JOIN sku_key_value v ON k.id_sku_key = v.id_sku_key
where k.id_sku_key = 5
and v.id_sku_language = 33;
What needs to be done to the ANSI JOIN statement to make it equivalent to the (+) join statement?
Thanks,
John

Answer 1

This change fixes the problem:
select k.key, NVL(v.value, k.en_value) as lvalue
from sku_key k
LEFT JOIN sku_key_value v ON (k.id_sku_key = v.id_sku_key
and (v.id_sku_language = 33
or v.id_sku_language is null))
where k.id_sku_key = 5
