In Oracle you can assign an alias to a table. So in the example below I select one field from table 1 and two fields from table 2. Then in the where clause I joined them together (PK to FK)

SELECT a.field1, b.field2, b.field3
FROM table1 a, table2 b
WHERE a.pk = b.fk
and a.field1 IS NULL

Hope this helps

Your left join is an Oracle Outer-Join.

Try something like:

SELECT DISTINCT ARBOR_COMMON_DATA_LAYOUT.ACCOUNT_CATEGORY
FROM ARBOR_COMMON_DATA_LAYOUT, ACCOUNT_CATEGORY
where ARBOR_COMMON_DATA_LAYOUT.ACCOUNT_CATEGORY (+) = ACCOUNT_CATEGORY.ACCOUNT_CATEGORY_ID
and ACCOUNT_CATEGORY.ACCOUNT_CATEGORY_ID IS NULL;

or maybe the other way around...

SELECT DISTINCT ARBOR_COMMON_DATA_LAYOUT.ACCOUNT_CATEGORY
FROM ARBOR_COMMON_DATA_LAYOUT, ACCOUNT_CATEGORY
where ARBOR_COMMON_DATA_LAYOUT.ACCOUNT_CATEGORY
= ACCOUNT_CATEGORY.ACCOUNT_CATEGORY_ID (+)
and ACCOUNT_CATEGORY.ACCOUNT_CATEGORY_ID IS NULL.

or using aliases to simplify...

SELECT DISTINCT x.ACCOUNT_CATEGORY
FROM ARBOR_COMMON_DATA_LAYOUT x, ACCOUNT_CATEGORY y
where x.ACCOUNT_CATEGORY = y.ACCOUNT_CATEGORY_ID (+)
and y.ACCOUNT_CATEGORY_ID IS NULL.
