Forget about Adaptive Query Processing for a minute, what other feature have I been waiting for? SELECT INTO a specific filegroup, not the default filegroup! I have needed this feature many times in the past. Let’s take a look at it using the WideWorldImportersDW database.
Times are changing, 10 years ago I would never have thought that self-tuning databases would be available as a packaged product. I was testing out SQL Server 2017 Automatic Tuning recently and I ended up with the following situation. Below shows an image from the query store.
I worked on testing interleaved execution with Microsoft back in January, I didn’t do much, just tested the functionality against some in-house code we had. (If you need a detailed primer on the subject, please see https://blogs.msdn.microsoft.com/sqlserverstorageengine/2017/04/19/introducing-interleaved-execution-for-multi-statement-table-valued-functions/)
I love the query store, it is powerful (can be dangerous) , easy to use and packed full of information. I use it frequently across my local SQL Servers and Azure SQL Database.
Let’s work through some code to do an encrypted backup. This feature is available to you if you are using SQL Server 2014 onwards but I decided to use SQL Server 2017.
To encrypt during backup, you must specify an encryption algorithm, and an “encryptor” to secure the encryption key. I have decided to use the following options:
- Encryption Algorithm: AES 256
- Encryptor: A certificate
