SQL Server 2012 Service Pack 2 is available – but there's a catch!
Service Pack 2 is available:
The build number is 11.0.5058, and this includes fixes up to and including SQL Server 2012 SP1 CU #9. (The complete list of fixes is exhaustive, including all fixes from SP1 CU #1 -> #9, but the post-CU #9 fixes are listed here:
However, if you may be affected by the regression bug I talked about earlier today, which could lead to data loss or corruption during online parallel index rebuilds, this regression did make it into the SP2 code, so if you are on SP1 you will want to take the hotfix linked in the blog post above, and if you plan to upgrade to SP2, there is a similar SP2 hotfix available from the same KB article.
You can not fix the problem simply by installing the hotfix to SP1 and then applying SP2 on top of that – Service Pack 2 will effectively remove all of the fixes you got from the hotfix. And you will not be able to install SP2 and then install an earlier CU (like SP1 CU #10) or the SP1 version of the hotfix. So if you plan to move to SP2, you need to keep both your current CU level and this critical hotfix in mind. If this doesn't meet your corporate policies, then you may want to wait for SP2 CU1, which should be available at the end of July 2014.
If you are just looking for Management Studio, you can download the new version from here:
You want the file SQLManagementStudio_x64_ENU.exe or, if you are still using an x86 machine, SQLManagementStudio_x86_ENU.exe.
