Question
Using Oracle, access the tables you created in Project 2 and complete the following SQL transactions. Log your statements and results by spooling your file (with echo on). All column headings must show in their entirety
11A
List the customer ID, customer first name, customer last name, and count of reservations for each customer. Combine the first and last name into one column. Sort by reservation count in descending order, then by customer ID in ascending order. Use the following column headings: CustomerID, CustomerName, ResCount. Hint: Use a GROUP BY clause.
11B
List all rows and all columns from the ResDetail table; sort by ResNum then by Room Num, both in ascending order. Use the following column headings: ResNum, RmNum, RateType, RateAmt.
12.
List the rate type, rate type description, and count of rooms reserved for each rate type. Sort by count in descending order. Use the following column headings: RateType, Description, ResCount. Hint: Use a GROUP BY clause.
13.
List the customer ID, customer first name, customer last name, and customer phone number for all customers. Show the phone number formatted as ‘(###) ###-####’ and sort by customer ID. Use the following column headings: Customer_ID, First_Name, Last_Name, Phone.
14
List the reservation number, room number, room type, room type description, rate type, rate type description, and rate amount of the room(s) with the lowest rate amount in each reservation. Sort by rate amount in descending order. Show the rate amount formatted as currency, and use the following column headings: ResNum, RmNum, RmType, RmDesc, RateType, RateDesc, RateAmt. Hint: use a GROUP BY clause and a nested SELECT.
15
List the room number, room type, room type description, rate type, and rate amount for each room for which reservations exist. Sort by room number then by rate amount.

Explanation / Answer
11 A) Two tables are joined and aggregate function COUNT is is to count the reservation along with group by clause. CONCAT() function is used to concat the first and last name.
SELECT c.CustID AS CustomerID, CONCAT(c.CustFName," ", c.CustLName) AS CustomerName, COUNT(r.ResID) AS ResCount
FROM Customer_abc c
INNER JOIN Reservation_abc r
ON r.CustID = c.CustID
GROUP BY c.CustID, CONCAT(c.CustFName," ", c.CustLName)
ORDER BY COUNT(r.ResID) DESC, CustID ASC;
11 B) Selecting all the detail from the reservation detail table. Order by is used to sort the result in specific order.
SELECT ResID AS ResNum, RoomNum AS RmNum, RateType, RateAmt
FROM ResDetail_abc
ORDER BY ResNum ASC, RmNum ASC;
12) Two tables are joined and aggregate function COUNT is used along with group by. Order by is used to sort the result on the basis of reservation count.
SELECT rt.RateType, rt.RateTypeDesc, COUNT(r.ResID) AS ResCount
FROM RateTpe_abc rt
INNER JOIN ResDetail_abc r
ON rt.RateType = r.RateType
GROUP BY rt.RateType, rt.RateTypeDesc
ORDER BY ResCount;
13) TO_CHAR() function is used to convert the phone to a specific format.
SELECT CustID, CustFName, CustLName, TO_CHAR(CustPhone, '(000)g000g0000', 'nls_numeric_characters=.-') AS phone
FROM Customer_abc;
14)
SELECT r.ResID, r.RoomNum, rm.RoomTypeDesc, , rt.RateType, rt.RateTypeDesc, MIN(rt.RateAmt)
FROM RateTpe_abc rt
INNER JOIN ResDetail_abc r
ON rt.RateType = r.RateType
INNER JOIN RoomType_abc rm
ON rm.RoomType = r.RoomType
GROUP BY r.ResID, r.RoomNum, r.RoomTypeDesc, , rt.RateType, rt.RateTypeDesc;
15)
SELECT r.RoomNum, r.RoomType, rt.RoomTypeDesc, ra.RateType, ra.RateAmt
FROM Room_abc r
INNER JOIN RoomType_abc rt
ON r.RoomType = rt.RoomType
INNER JOIN ResDetail_abc rd
ON rd.RoomNum = r.RoomNum
INNER JOIN RateType_abc ra
ON ra.RoomType = rd.RoomType
ORDER BY r.RoomNum, ra.RateAmt;
