Inserting data directly into a table as an array

Dear friends,

I have a scenario SAP <-> PI <-> Oracle DB. Its a synchronous scenario...

I get 3 fields from SAP and the structure looks like this:

<ns0:TestReq">

   <Table> 1..n

      <New/>

      <Old/>

      <Date/>

   </Table>

</ns0:TestReq>

Ive to insert this structure as an array into a DB.

The Package.Stored Procedure looks like this

Test.testing     (                                        updatetable          IN           Update_Table,

                                                               errortable             OUT        Update_Connect_Table,

                                                               errorcode             OUT        VARCHAR,

                                                                                                                    )

Can you please help me how to achive this? How can I insert this structure directly into a table as an array and keeping in mind with performance, because it can be alot of records at once.

Thank you in advance,

Kind regards,

John
