Cumulative update
Cumulative updates (CU) are now available at the Microsoft Download Center.
Only the most recent CU that was released for SQL Server 2017 is available at the Download Center.
CU packages for Linux are available at https://packages.microsoft.com/.
Notes
- Each new CU contains all the fixes that were included with the previous CU for the installed version of SQL Server.
- SQL Server CUs are certified to the same levels as Service Packs, and should be installed at the same level of confidence.
- Microsoft recommends ongoing, proactive installation of CUs as they become available according to these guidelines:
- 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.
- We recommend that you test CUs before you deploy them to production environments.
How to obtain this cumulative update package for Windows
SQL Server 2017 CU13 regression for Analysis Services (only)
The Analysis Services component of the SQL Server 2017 CU13 hotfix patch can cause certain DAX queries to fail with error: An unexpected exception occurred.
This error can occur in queries using the TREATAS function, common in Power BI generated DAX queries. It is recommended you do not install the SQL Server 2017 CU13 hotfix on computers with Analysis Services instances when Power BI Desktop or Power BI Service is a client querying that server instance.
A fix for this issue will ship in the next SQL Server 2017 Cumulative Update.
The following update is available from the Microsoft Download Center:
