Answer 1

Ok here a simple Query for the Quantities and Order Price

SELECT p.Description, psw.qtysum, psw.opsum, psm.qtysum, psm.opsum
FROM Products p
LEFT JOIN
  ( SELECT sw.product_id, SUM( sw.QTY ) AS qtysum, SUM( sw.`order price` ) AS opsum 
    FROM orders sw 
    WHERE WEEK( sw.`purchase date`) = WEEK( current_date )
    AND YEAR( sw.`purchase date`) = YEAR( current_date )
    GROUP BY sw.product_id ) psw 
  ON p.id = psw.product_id

LEFT JOIN
  ( SELECT sm.product_id, SUM( sm.QTY ) AS qtysum, SUM( sm.`order price` ) AS opsum 
    FROM orders sm 
    WHERE MONTH( sm.`purchase date`) = MONTH( current_date )
    AND YEAR( sm.`purchase date`) = YEAR( current_date )
    GROUP BY sm.product_id ) psm 
  ON p.id = psm.product_id
