Features that were deprecated in prior releases are also deprecated in SQL Server 2022 (16.x):

Deprecation guidelines

When a feature is marked deprecated, it means:

  • The feature is in maintenance mode only. No new changes are made, including changes to address interoperability with new features.

  • We strive not to remove a deprecated feature from future releases to make upgrades easier. However, under rare situations, we might choose to permanently discontinue (remove) the feature from SQL Server if it limits future innovations.

  • For new development work, don't use deprecated features. For existing applications, plan to modify applications that currently use these features as soon as possible.

You can monitor the use of deprecated features by using the SQL Server Deprecated Features Object performance counter, or the deprecation_announcement and deprecation_final_support extended events. For more information, see Use SQL Server Objects.

Query deprecated features

The values of these counters are also available by executing the following statement:

SELECT * FROM sys.dm_os_performance_counters   
WHERE object_name LIKE '%SQL%Deprecated Features%';
