'Write a Procedure, cursor to display cars
I have these tables:
- Car (CarID, brand, Buyprice, YearManufacture, Color)
- Client (ClientId, name, address, salary)
- Vendor (VendorID, name)
- Sale (CarID, ClientID, VendorID, SaleDate, SalePrice)
I have to write a procedure for displaying all cars. If car is of type 'Mercedes', show its purchase price and whether it is already sold or not.
This is my code:
CREATE PROCEDURE PD
AS
BEGIN
DECLARE Crs CURSOR FOR
SELECT CarID, brand, Buyprice
FROM Car;
DECLARE @Carid INT;
DECLARE @Type varchar (100);
DECLARE @Price INT;
DECLARE @N INT;
OPEN Crs;
FETCH Crs INTO @Carid, @Type, @Price;
WHILE @@Fetch_status = 0
IF @Type = 'MERCEDES'
BEGIN
PRINT @Price;
SELECT @N = COUNT(*)
FROM Sale
WHERE CarID = @Carid;
IF @N > 0
BEGIN
PRINT 'Car already sold');
ELSE
PRINT 'Car is sold');
END
END
END;
CLOSE Crs;
DEALLOCATE Crs;
END;
Is it correct, or am I missing something?
