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
