Re: Issue with the Full Outer join

Hi Krishna,

Whenever we trigger "Full outer join" on top of multiple tables with reference to a common column from both tables. The result set will contain both the columns(common columns). see below.

select * from "CUSTOMER" AS T1 FULL OUTER JOIN "ORDERS"AS T2 ON T1."CUSTOMERID" = T2."CUSTOMERID"

In above query--> column1 "CustomerID" coming from T1 table and column4 "CustomerID" coming from T2 table.

in your question you were trying to retrieve the data of "CustomerID" from T1 table.That's why you were missing "C5" entry.

I hope this explanation will help you.

Thanks & regards,

sai krishna.
