This article describes Cumulative Update package 18 (CU18) (build number: 12.0.5687.1) for Microsoft SQL Server 2014 Service Pack 2 (SP2). This update contains fixes that were released after the initial release of SQL Server 2014 SP2.

Cumulative update

Cumulative updates (CU) are now available at the Microsoft Download Center.

Only the most recent CU that was released for SQL Server 2014 SP2 is available at the Download Center.

  • Each new CU contains all the fixes that were included with the previous CU for the installed version or service pack of SQL Server.

  • Microsoft recommends ongoing, proactive installation of CUs as they become available:

    • SQL Server CUs are certified to the same levels as Service Packs, and should be installed at the same level of confidence.

    • Historical data shows that a significant number of support cases involve an issue that has already been addressed in a released CU.

    • CUs may contain added value over and above hotfixes. This includes supportability, manageability, and reliability updates.

  • Just as for SQL Server service packs, we recommend that you test CUs before you deploy them to production environments.

  • We recommend that you upgrade your SQL Server installation to the latest SQL Server 2014 service pack.

Notes for this update

Hybrid environments deployment

When you deploy an update to a hybrid environment (such as AlwaysOn, replication, cluster, and mirroring), we recommend that you refer to the following articles before you deploy the update:

Language support

  • SQL Server Cumulative Updates are currently multilingual. Therefore, this cumulative update package is not specific to one language. It applies to all supported languages.

Components (features) updated

One Cumulative Update package includes all available updates for ALL SQL Server 2014 components (features). However, the cumulative update package updates only those components that are currently installed on the SQL Server instance you select to be serviced.  If a SQL Server feature (e.g. Analysis Services) is added to the instance after this CU is applied, you must re-apply this CU to update the new feature to this CU.

Support for this update

If additional issues occur or if any troubleshooting is required, you might have to create a service request. The usual support costs will apply to additional support questions and to issues that do not qualify for this specific cumulative update package. For a complete list of Microsoft Customer Service and Support telephone numbers or to create a separate service request, go to the Microsoft support website.

How to uninstall this update

  1. In Control Panel, select View installed updates under Programs and Features.

  2. Locate the entry that corresponds to this cumulative update package under Microsoft SQL Server 2014.

  3. Press and hold (or right-click) the entry, and then select Uninstall.
