Question of the Day

The Empty Aggregate

I have this table in a SQL Server 2025 database: 

CREATE TABLE [dbo].[CustomerOrder]
(
[OrderID] [int] NULL,
[CustomerID] [int] NULL,
[total] [money] NULL
) ON [PRIMARY]
GO
What is returned from this code? (answers are for the sum and then the count) 
SELECT SUM(total) AS sum,
       COUNT(total) AS count
FROM dbo.CustomerOrder;

See possible answers
