I started with blogging about COUNT = 0 situation. Then I followed it with COUNT = 1. So, let’s do a COUNT = 2 today. No, no, I am just kidding, don’t worry 🙂 But I still have to do one more COUNT post, one that will cover all other COUNT situations.
Believe it or not, sometimes you really, honestly, do need to perform an actual COUNT. You just need to know exactly how many of rows there are. It may be 0, 1 or 75 or whatever, but you need to know exactly how many. These situations are few and far between, but every once in a long while this is what you need.
So, let’s give the COUNT function one last kick from another angle.
Performance is one of those things you can’t get enough of and NAV is one of those systems where an extra operation per second is always welcome. Yesterday, during the Expert Panel at the NAV day of the Decisions Spring conference, there was a question: is there any improvement in how NAV 2013 works on SQL Server.
And the answer is: oh yeah!
As a matter of fact, everything is new and improved.
Jörg has already posted an overview of the news of NAV on SQL Server in his last blog post, but I still think there’s room for a couple of more words on the really amazing palette of news and improvements.
