SQL for View Definition using outer join

Question

Hello everyone,
I am creating a view using the statement below
SELECT *
FROM table_a A
,table_b B
,table_c C
WHERE A.sg_code = B.sg_code and
B.st_code = 'E' and
A.sg_code = C.sg_code(+) and
C.st_code = 'T'
The structure of the view is as follows
View
sg_code| Name | start_date | end_date |
1 | Test |13-03-2008 | NULL |
Table_a
sg_code,Name
Table_b
sg_code,st_code,actual_date
the view can have a null for the column 'end_date'
This means there will not be a record inserted in the Table_b for end_date=null, there will only be a record for actual_date=start_date
In this scenario when I query the view I am not seeing the newly created record just because there is a condition "C.st_code = 'T'" with the outer join on the sg_code.
When I look into the individual tables I see the records.
Table A
Pg_code,Name
1 Test
Table B
Id pg_code As_of_date
1 1 13-03-2008
How should I modify my view definition so that I can query the view even if there is a null for 'end_date'
Thanks

Answer 1

the last line should be:
C.st_code(+) = 'T'
by failing to include the (+) on that line, you made it NOT an outer join. an outer joined table must be outer joined on every where criteria, including to constants.
