When I use
select @@version
then I get:
Microsoft SQL Server 2008 R2 (SP1) - 10.50.2500.0 (Intel X86)
Jun 17 2011 00:57:23
Copyright (c) Microsoft Corporation
Express Edition with Advanced Services on Windows NT 6.1 (Build 7601: Service Pack 1) (WOW64)
But in Control Panel I see that yesterday I have installed 10.53.6000.34
Yesterday after upgrade I restart entire Windows.
Question: So my question is why does select @@version return me information that I still have SP1?
btw.
I saw this question: Upgrade to SQL Server 2017 from SQL Server 2008 R2
I also check: https://sqlserverbuilds.blogspot.com/
and I think that I use proper upgrade pack/installer.
