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/)
Let’s start off with a quick overview of SQL Server versions and compatibility levels.
So with SQL Server 2017 now available to the public what level is a newly created Azure SQL Database set at?
I used to be on the fence regarding whether or not Automatic Tuning should be on as the default when creating Azure SQL Databases. A part of me never liked the idea of Azure creating/dropping indexes or forcing plans without my prior approval but then again if it happens to do the right thing at the right time then it’s a pleasurable experience.
With Halloween around the corner what better topic to discuss than phantom reads. A phantom read occurs when rows have been inserted after a read operation and becomes visible in a follow-up read operation within the same transaction.
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.
