SQL SERVER 2016: Creating Simple Temporal Table

February 10, 2016

SQL Scripts, SQL Server, SQL Server 2016, SQL Utility, Temporal Table

Temporal tables are a new feature that was introduced in SQL Server 2016. A temporal table gives application developers to view the state of data at a point in time. Temporal tables can also be used for logging purposes if required. I wanted to explore how this feature can be used. The documentation has been interesting and I went ahead in trying out how this can be enabled.

One of the most used use case for this feature would be to find the data values in a past date. This can now be easily configured in SQL Server 2016. Let us go ahead and create a database for use and then create a table with the Temporal history database created by default / automatically.

Sometimes it is needed to connect to SQL Server using System account. Don’t literally ask me if this is a valid scenario in first place. Someone just pinged to say – they want to do it. I was personally not sure why, but they had their own internal requirement to do the same. Let us learn about in this blog post about how to connect using NT AUTHORITY \ SYSTEM Account?

It is not possible to provide windows credential in SSMS and they are always grayed out. My exploration is always to keep trying to find a solution to such typical use cases. I was able to find that PSExec can be used to achieve this. I am a big fan of some of the tools from sysinternals. These are handy and quite small footprint of the servers. One of the tools I have day-in day-out is ZoomIt while doing presentations.

Doing repetitive tasks is something everyone hates. I am sure many of us have resorted to ingenious techniques to figure out doing the task efficiently. There is no standard tool or technique that everyone uses. Recently I was asked to install a SQL instance with same configuration on 10 servers. Who would like to log in to all those servers, run setup.exe and go through the same setup wizard? Luckily, the SQL Server setup allows to create a configuration file. The very thought of extracting it as configuration is something that made me jump out of my seat. Let us learn about Install Error – The /UIMode setting cannot be used in conjunction with /Q or /QS.

The experimentation of working with the next release of SQL Server is always fun and when I wrote the blog T-SQL Enhancement “Drop if Exists” clause, lesser did I know such capabilities are already existing with Azure SQL DB.

One of the attendees asked, has all features first introduced to cloud only? Let us learn about IF EXISTS Function on SQL Azure Databases and More.
