Hi Experts,

I want to do outer join on two tables:

create table sunil1234
(data1  NUMBER NOT NULL,data2 VARCHAR2(2),
data3  NUMBER(10) NOT NULL,
data4 FLOAT(126),
data5  NUMBER NOT NULL,
data6 number);

create table sunil123456(data7  NUMBER NOT NULL,data1   NUMBER NOT NULL,
data2 VARCHAR2(2),data8  NUMBER(10) NOT NULL,data9  FLOAT(126),data5  NUMBER NOT NULL,
data6 number);


insert into sunil1234 values(1,'A',123,123.5,091108,4);
insert into sunil1234 values(2,'B',223,223.5,091109,5);

insert into sunil123456 values(5,'1','A',8,111.5,091108,4);
insert into sunil123456 values(5,'2','B',9,112.5,091109,5);
insert into sunil123456 values(5,'3','C',10,113.5,091106,6);

Commit;

2 rows selected





I am expecting 3 rows in the outer join select statement.

Please look into it.

Thanks and Regards,
Sunil

Do the outer join the other way round if you want to get all the rows from SUNLIN123456 and data from SUNLIL1234 if it exists.

SELECT * FROM sunil1234 a,sunil123456 b WHERE  a.data2(+)=b.data2;


[remember to actually change the select. D'oh]
