Is SharePoint 2010 supported on SQL server 2012 SP2?
Thanks...
As a short answer: Yes, It's supported,
In order to use Microsoft SQL Server 2012 SP2, you must use SharePoint 2010 SP1 or later of SharePoint Server 2010!
Note:
In order to maintain SharePoint and SQL Server compatibility Microsoft use the
“SharePoint N-1 on SQL Server N+1”
equation to determine version support. Using SharePoint Server 2010 as an example, the N release of SQL Server is 2008/2008 R2 and N+1 is SQL Server 2012.
Based on the above N equation, the SharePoint 2010 SP 1 is supported on SQL Server 2012, so it also supported on SQL Server 2012 SP1 and SP2 ...etc
