RE: Retrieval Query

Richard,

Try this:

select po_price from header_table a, detail_table b where a.po_num=b.po_num
and a.po_date=(select max(po_date) from header_table);

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
