Oracle 8i -multiple LEFT OUTER JOIN

Question

Hi,
I have to convert some stored procedure from Sql Server to Oracle 8i where I have multiple LEFT OUTER JOIN on a table. Because Oracle 8i accept only one outer join on a table how can I convert this:
select a.id, b.id
from test as a LEFT JOIN test1 b ON a.id(+)=b.id
and a.display(+)=b.display
and a.name(+)='Done';
Thanks.

Answer 1

FROM test a LEFT JOIN test1 b ON b.key = a.keyis equivalent to
FROM test a, test1 b WHERE b.key(+) = a.keyThere is a restriction (when using the "(+)" syntax) that a table may be outer-joined to at most one other table, but that does not prevent you from having multiple join conditions between those two tables.
From your example I'm not sure whether you need this:
SELECT a.id, b.id
FROM   test a
     , test1 b
WHERE  a.name = 'Done'
AND    b.id (+)= a.id
AND    b.display (+)= a.display;or this:
SELECT a.id, b.id
FROM   test1 b
     , test  a
WHERE  a.id (+)= b.id
AND    a.display (+)= b.display;
WHERE  a.name (+)= 'Done';
