Decompose the following SELECT statement to show the intermediate table before grouping. Your answer should contain a SELECT statement without the GROUP BY clause. You should be able to compute the aggregate functions using the intermediate generated by your SELECT statement answer.

SELECT Customer.CustNo, CustFirstName, CustLastName, SUM(Qty) AS ProdQty, 

SUM(Qty*ProdPrice) AS TotOrdAmt

FROM OrderTbl, OrdLine, Product, Customer

WHERE OrdDate BETWEEN '1-Jan-2021' AND '31-Jan-2021'

AND OrderTbl.OrdNo = OrdLine.OrdNo

AND OrdLine.ProdNo = Product.ProdNo

AND Customer.CustNo = OrderTbl.CustNo

AND (ProdName LIKE '%Ink Jet%'

OR ProdName LIKE '%Laser%')

GROUP BY Customer.CustNo, CustFirstName, CustLastName

HAVING SUM(Qty) > 2;
