SDU Tools: Last SQL Server Restart

Our free SDU Tools for developers and DBAs, now includes a very large number of tools, with procedures, functions, and views. A request that I had a while back was to have a function that returned the last time that SQL Server was restarted. So we added the LastSQLServerRestart function.

It takes no parameters.

I used to have a more complex way to work this out, but thanks to a great suggestion from our buddy Rob Wylie, it now just looks for the creation time of tempdb. That’s pretty good and simple to implement.

You can see it in action in the main image above, and in the video here. The full current version of the code is also shown below:

You can use our tools as a set or as a great example of how to write functions like these.

Access to SDU Tools is one of the benefits of being an SDU Insider, along with access to our other free tools and eBooks. Please just visit here for more info:
