Hello All,

In one of the report requirements we have to link 2 tables and if data is not available in one of the table in the report output the other column data should be displayed.

Example:

We have 2 tables shipment,order_release.Even shipment is not existing for this order_release in the output the order_release alone need to be displayed.

select shipment_id,order_release_id
from shipment s,order_release orl,link_table lt
where s.shipment_id=lt.shipment_gid
and orl.order_release_id=lt.order_release_id

Output: shipment_id order_release
....... 12374
....... 83460
23459 ......
34785 43987

Can any one help in achieving this?

Thanks in Advance.

Regards,
Lakshmi.

Is it OUTER JOIN you are looking for?

Yes Littlefoot,

Thanks for the response.
Will the performance of the report go worst by using outer joins?
as i have many tables involved in the original query and all need to fetch data in the below fashion.

Kindly Advice.

Regards,
Lakshmi.

If outer-join is required to get the result you need then performance is a bit irrelevant - it might well slow it down, but you'll probably have to live with that - suggest you test it.

EDIT: typo
