Home -> Community -> Mailing Lists -> Oracle-L -> RE: Outer join in SQL server - A very simple question
IIRC, the "*=" from Sybase and SQLServer is placed on the
opposite side of Oracle's "(+)" for the same affect.
i.e.
ORACLE:
select a.*,
b.*
from a,
b
where a.x(+) = b.x
select a.*,
b.*
from a,
b
where a.x =* b.x

This does the same.......
SELECT a1, b1, c1, d1
FROM
t1
left join t2 on t1.a=t2.b
left join t3 on t2.b=t3.c
left join t4 on t1.a2=t4.d

Please read "INSERT INTO t4 VALUES ('A', 'DD');" as "INSERT INTO t4 VALUES ('AAAA', 'DD');" in my previous mail.
