Consider the following table structure:
CREATE TABLE Orders (
  OrderID INT PRIMARY KEY,
  OrderDate DATE,
  TotalAmount DECIMAL(10, 2),
  CustomerID INT
);
Which of the following SQL statements will return the customer ID(s) with the highest total amount spent on orders?
  • a)
    SELECT CustomerID FROM Orders WHERE TotalAmount = (SELECT MAX(TotalAmount) FROM Orders);
  • b)
    SELECT CustomerID FROM Orders GROUP BY CustomerID HAVING SUM(TotalAmount) = (SELECT MAX(SUM(TotalAmount)) FROM Orders GROUP BY CustomerID);
  • c)
    SELECT CustomerID FROM Orders WHERE TotalAmount = MAX(SELECT MAX(TotalAmount) FROM Orders GROUP BY CustomerID);
  • d)
    SELECT CustomerID FROM Orders WHERE TotalAmount = (SELECT MAX(SUM(TotalAmount)) FROM Orders GROUP BY CustomerID);
Correct answer is option 'B'. Can you explain this answer?

Consider the following table structure:CREATE TABLE Orders ( OrderID I...
The SQL statement SELECT CustomerID FROM Orders GROUP BY CustomerID HAVING SUM(TotalAmount) = (SELECT MAX(SUM(TotalAmount)) FROM Orders GROUP BY CustomerID); retrieves the customer ID(s) with the highest total amount spent on orders. It uses aggregation functions and subqueries to calculate the sum of TotalAmount for each customer ID and then compares it to the maximum sum.
