-- Use the newly created database
USE SampleDB;

CREATE TABLE Customers (
    CustomerID INT PRIMARY KEY,
    FirstName VARCHAR(50),
    LastName VARCHAR(50),
    Email VARCHAR(100),
    Birthdate DATE,
    RegistrationDate DATETIME
);

-- Insert some sample data into the Customers table
INSERT INTO Customers (CustomerID, FirstName, LastName, Email, Birthdate, RegistrationDate)
VALUES
    (1, 'John', 'Doe', 'john.doe@example.com', '1985-05-10', '2023-01-15 08:30:00'),
    (2, 'Jane', 'Smith', 'jane.smith@example.com', '1990-08-20', '2023-02-20 11:45:00'),
    (3, 'Michael', 'Johnson', 'michael.johnson@example.com', '1988-11-05', '2023-03-10 14:15:00');

-- Create a table for orders
CREATE TABLE Orders (
    OrderID INT PRIMARY KEY,
    CustomerID INT,
    OrderDate DATE,
    TotalAmount DECIMAL(10, 2),
    FOREIGN KEY (CustomerID) REFERENCES Customers(CustomerID)
);

-- Insert some sample data into the Orders table
INSERT INTO Orders (OrderID, CustomerID, OrderDate, TotalAmount)
VALUES
    (1, 1, '2023-04-05', 150.00),
    (2, 2, '2023-05-12', 200.00),
    (3, 1, '2023-06-20', 75.50);

-- Query to retrieve customer information along with their total order count
SELECT 
    c.CustomerID,
    c.FirstName,
    c.LastName,
    COUNT(o.OrderID) AS TotalOrders
FROM Customers c
LEFT JOIN Orders o ON c.CustomerID = o.CustomerID
GROUP BY c.CustomerID, c.FirstName, c.LastName;

-- Update customer email
UPDATE Customers
SET Email = 'updated.email@example.com'
WHERE CustomerID = 1;

-- Delete an order
DELETE FROM Orders
WHERE OrderID = 3;

SELECT 
    SUM(TotalAmount) AS TotalRevenue
FROM Orders;

-- Drop the tables and the database
DROP TABLE Orders;
DROP TABLE Customers;
DROP DATABASE SampleDB;
