Cumulative Updates - SQL Server 2012 RTM CU9
A 9th Cumulative Update is available for those users still on the RTM branch of SQL Server 2012. This is in keeping with Microsoft’s Incremental Service Modelling.
You may have to restart your machine before the update is applied. Please check that the hotfixes which are included in this cumulative update package are relevant to you, though some of these seem fairly important, such as poor performance when you run a query that uses the LIKE operator in the WHERE clause.
This CU fixes 7 bugs, but an additional 8th issue is resolved. The version number will now be 11.0.2419.0.
