How Big is Your Transaction Log?

If you are not managing the transaction log space used by a database, the transaction log might grow uncontrollably. With SQL Server 2017 there is a new dynamic management function (DMF) that exposes statistical information about a database transaction log. One of the things you can do with the information returned from this DMF is to determine how full a database transaction log file is.

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;
