Phil Factor argues that the database should be the primary source not only of the current data values, but also of the volatility of the data, its rate of change. Surely, then, it makes sense for the database to control the caching strategy.
When you are automating a number of tasks, or performing a batch of tests, you want a way of automating the production of your plots and graphs. Nothing beats a good graphical plot for giving the indications of how the process went. If you are using PowerShell and maybe also SQL Server, it pays to use a command-line plotting tool such as Gnuplot to do all the hard work. It turns out to be handy for a range of data jobs, turning PowerShell into a handy data science tool.
If you’re a Redgate SQL Backup customer, occasionally you’ll need to convert your SQL Backup (.sqb) files to the native SQL Server backup format (.bak), perhaps to perform native database restores on a server where SQL Backup isn’t installed. This produces a striped backup, because each thread used when making the backup will produce a separate file. Can we use a striped backup produced in this way, or indeed any striped backup, as the source for a SQL Clone image? Short answer: we can! Let’s see how that works.
The SQL Server platform is growing, but Steve Jones notes that this might not really affect our jobs.

This article from Tony Davis describes how to the use the Redgate SQL Compare and SQL Data Compare GUIs to get the current version of a database schema, and its static data, into version control, and then automate database deployments from the version control system using SQL Compare's command line and PowerShell.
Monica Rathburn talks about a few of the more common elements she always checks for when troubleshooting I/O problems.
We will start to deal with more and more types of data. Steve Jones worries about the possibility of hacking.

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] GOWhat 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;
