Deprecated database engine features in SQL Server 2019 (15.x)

Applies to: yesSQL Server 2019 (15.x)

SQL Server 2019 (15.x) does not deprecate any features beyond those deprecated in prior releases:

Deprecation guidelines

When a feature is marked deprecated, it means:

  • The feature is in maintenance mode only. No new changes will be done, including those related to addressing inter-operability with new features.
  • We strive not to remove a deprecated feature from future releases to make upgrades easier. However, under rare situations, we may choose to permanently discontinue (remove) the feature from SQL Server if it limits future innovations.
  • For new development work, do not use deprecated features. For existing aplications, 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 = 'SQLServer:Deprecated Features';
