Earlier last week, I was presenting various questions about SQL Server 2017 at PASS in Seattle. However, during one of the session, I was fortunate to meet SQL Server Expert Christopher Savage. He shared a very interesting puzzle with me. I have been trying to solve the puzzle for a while, but I have no answer for it. Let us see the puzzle about DateTime2 Conversion in SQL Server 2017.
It has been awhile since I asked any puzzle on SQLAuthority.com, Let us see a very simple puzzle today which involves execution plan as well.
First of all this observation is only applicable if you are using SSMS 17.7 build. It was very interesting to me that I was able to find two Miscellaneous categories in Database Property Option for SQL Server. Please note the version of SQL Server which I have connected to SSMS 17.7 is also SQL Server 2017. If you try following on any other SSMS version you may not get the same results.
There are many different datetime related functions such as DAY, MONTH, YEAR, DATEDIFF, etc available in SQL Server. For example, YEAR function can be used to extract year value from a date.
The matter of the fact when I discovered this puzzle related to the stored procedure and unexpected results, I was very much surprised as well.
Today’s puzzle is very interesting and I am confident that you will find that very interesting. Today’s puzzle is about Table Qualifier. I have not talked about this subject on my blog for a while, and I feel confident that you will like it very much.
Recently I have been engaged with a customer where they were having a performance issue. They have engaged me via my offering Comprehensive Database Performance Health Check. While doing that, they asked me to write a better way to write a query. While I have given some suggestions and asked them to check, this looks like a nice puzzle to ask. So here we go to see the puzzle – Get the First Name From Full Name Without CHARINDEX.
