A number of security-related features are built into Azure SQL Database, including Transparent Data Encryption, Row-Level Security, and Azure SQL Database Auditing. Their availability reflects the consistent effort by Microsoft to provide functional parity between Azure SQL Database and SQL Server instances running in Azure virtual machines as well as in your on-premises environment. Another example of this trend is support for Dynamic Data Masking, covered in this article.
Tables that return the value of the data in the table at a particular point of time have been with us since the first relational database, but have always required special queries and constraints, and can be tricky to get right. System-versioned Temporal Tables, new in SQL Server 2016, make such tables behave like any other. How do you create one, or modify an existing table? How can you get an In-Memory Optimized OLTP table to be Temporal? Alex Grinberg shows how.
Using clustering algorithms to analyse index usage data from SQL Server’s DMVs & simplify complex performance investigations.
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.

I have a database, DNRTest, that has a number of tables and other objects in it. The other day, I was trying to mock up a test and ran this code on the same server:
-- run yesterday CREATE DATABASE DNRTest2 GO USE DNRTest2 GO CREATE TABLE NewTable (id INT) GOToday, I realize that I need a copy of DNRTest for another mockup, and I run this:
-- run today USE Master BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak' GO RESTORE DATABASE DNRTest2 FROM DISK = 'dnrtest.bak' WITH REPLACEWhat happens? See possible answers
