Because Oracle 8i now allows an ORDER BY in a "dynamic" view (as we call them here), you could do the following:

SELECT po_price
  FROM (SELECT dtls.po_price

          FROM po_hdr hdr,
               po_dtls dtls
         WHERE hdr.po_num = dtls.po_num
           AND dtls.po_material = :literal
         ORDER BY hdr.po_date DESC)       

 WHERE rownum = 1;

Hi Experts

I have the header table

PO_NUM, PO_DATE and the detail table

PO_NUM, PO_MATERIAL, PO_PRICE. I want to take the unit price of a material which is bought recently
(latest purchase order date) ?

Thanks

Richard
