  • Applies to: SQL Server 2022 on Windows, SQL Server 2022 on Linux

Release Date:   November 13, 2025
Version:   16.0.4225.2

Summary

This article describes Cumulative Update package 22 (CU22) for Microsoft SQL Server 2022. This update contains 20 fixes that were issued after the release of SQL Server 2022 Cumulative Update 21. It updates components in the following builds:

  • SQL Server - Product version: 16.0.4225.2, file version: 2022.160.4225.2
  • Analysis Services - Product version: 16.0.43.252, file version: 2022.160.43.252

Known issues in this update

Incorrect behavior of SESSION_CONTEXT in parallel plans

Queries that use the built-in SESSION_CONTEXT function might return incorrect results or trigger access violation (AV) dump files when run in parallel query plans. This issue occurs because of the manner in which SESSION_CONTEXT interacts with parallel execution threads, particularly if the session is reset for reuse.

For more information, see the Known issues section in SESSION_CONTEXT.

A downloadable Microsoft Excel workbook that contains a summary list of builds, together with their current support lifecycle, is available. The Excel file also contains detailed fix lists for SQL Server 2022, SQL Server 2019, and SQL Server 2017. Download this Excel file now.

Important notices

This article also provides the following important information.

Analysis Services CU build version

Cumulative updates (CU)

  • 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.
  • We recommend 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 might contain added value over and above hotfixes. This includes supportability, manageability, and reliability updates.
  • We recommend that you test SQL Server CUs before you deploy them to production environments.
Hybrid environment deployment

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

Language support

SQL Server CUs are currently multilingual. Therefore, this CU package isn't specific to one language. It applies to all supported languages.

Components (features) updated

One CU package includes all available updates for all SQL Server 2022 components (features). However, the cumulative update package updates only those components that are currently installed on the SQL Server instance that you select to be serviced. If a SQL Server feature (for example, Analysis Services) is added to the instance after this CU is applied, you must reapply this CU to update the new feature to this CU.

Support for this update

If other 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 don't 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.
