Welcome to release 17.5 of SQL Server Management Studio (SSMS)! 

See also full documentation of this release and previous releases.


When you apply this update through Windows Server Update Services (WSUS), it is only applicable to earlier versions of SSMS 17.x. This package will fully upgrade any previous 17.x version.


Data Discovery and Classification:

  • Added a new SQL Data Discovery and Classification feature for discovering, classifying, labeling, and reporting sensitive data in your databases.

  • Auto-discovering and classifying your most sensitive data (business, financial, healthcare, PII, and so on) can play a pivotal role in your organizational information protection stature.

  • Learn more at SQL Data Discovery and Classification.

Query Editor:

  • Added support for the SkipRows option to the Delimited Text External File Format for Azure SQL Data Warehouse. This capability allows users to skip a specified number of rows when they load delimited text files into SQL Data Warehouse. Also added the corresponding intellisense and SQL Server Management Objects (SMO) support for the FIRST_ROW keyword.

Bug fixes


  • Fixed the Live Query Statistics (LQS) elapsed time to show the engine execution time instead of time that's elapsed for the LQS connection.

  • Fixed an issue in which showplan was not able to recognize Apply logical operators such as GbApply and InnerApply.

  • Fixed an issue that's related to ExchangeSpill.

Query Editor:

  • Fixed an issue that's related to SPIDs in which SSMS could throw an error message that resembles "Input string was not in a correct format. (mscorlib)" when you run a simple query that's preceded by a "SET SHOWPLAN_ALL ON".


  • Fixed an issue in which SMO was not able to fetch AvailabilityReplica properties in case the server collation was case-sensitive (and therefore, SSMS could display an error message that resembles "The multi-part identifier "a.delimited" could not be bound.").

  • Fixed an issue in the DatabaseScopedConfigurationCollection class in which incorrectly handling collations occur (and therefore, an SSMS that's running on an machine with a Turkish locale could display an error message that resembles "legacy cardinality estimation is not valid scoped configuration" when you right-click a database that's running on a server with a case-sensitive collation).

  • Fixed an issue in the JobServer class in which SMO was not able to fetch SQL Server Agent properties on a SQL Server 2005 server (and therefore, SSMS was throwing an error message that resembles "Cannot assign a default value to a local variable. Must declare the scalar variable "@ServiceStartMode" and, ultimately, SSMS was not displaying the SQL Server Agent node in Object Explorer).


Object Explorer:


  • Fixed an issue for the Merge Audit Files feature.

Known issues

Data classification:

  • Removing a classification and then manually adding a new classification for the same column result in the old information type and sensitivity label being assigned to the column in the main view.

    Workaround: Before saving, assign the new information type and sensitivity label after the classification is added back to the main view.
