How to determine the service pack of Sql Server I am having a sql server 2012 enterprise edition installed on my win 2012 r2 server.

But i am unable to determine whether its installed with service pack or not.
how to find out which service pack is installed ?
Here is my screen shot, and my screen shot says that , its a ent.edition
with version number:11.2.5058.0 .



When I serached in msdn, i didnot see this version number in any of the service packs of sql server 2012.
You can execute 

SELECT @@VERSION;


Which will give you the relevant information (note the bold, italicised SP1 from the example results)
