Merge into table using cursor

Question

Hi,
I am trying to merge into test table using a cursor.
If the contract number in the test table matches with the contract number from the cursor then i need to update the creation_date else i need to insert values from the cursor into the test table. I know this is wrong usage of cursor, but i would appreciate suggestions regarding this.
FOR i IN cursortest
MERGE INTO test
         USING cursortest
ON (i.contract_number = test.contract_number)
         WHEN MATCHED THEN
            UPDATE
               SET creation_date = SYSDATE
         WHEN NOT MATCHED THEN
            INSERT (customer_id, contract_number, creation_date)
            VALUES (i.customer_cpr_id, i.contract_number,SYSDATE);
end loop;

end loop;I think you're close. MERGE is designed to do a subquery internally, pretty much what I think you are trying to do in your cursor. Put the subquery into your using clause and see how that works. You can see examples in the on-line documentation
