SQL Server PowerShell Provider
The SQL Server provider for Windows PowerShell exposes the hierarchy of SQL Server objects in paths similar to file system paths. You can use the paths to locate an object, and then use methods from the SQL Server Management Object (SMO) models to perform actions on the objects.
There are two SQL Server PowerShell modules; SqlServer and SQLPS. The SQLPS module is included with the SQL Server installation (for backwards compatibility), but is no longer being updated. The most up-to-date PowerShell module is the SqlServer module. The SqlServer module contains updated versions of the cmdlets in SQLPS, and also includes new cmdlets to support the latest SQL features.
Previous versions of the SqlServer module were included with SQL Server Management Studio (SSMS), but only with the 16.x versions of SSMS. To use PowerShell with SSMS 17.0 and later, the SqlServer module must be installed from the PowerShell Gallery. To install the SqlServer module, see Install SQL Server PowerShell.
Benefits of the SQL Server PowerShell Provider
The paths implemented by the SQL Server provider enable easily and interactively reviewing all of the objects in an instance of SQL Server. You can navigate the paths using Windows PowerShell aliases similar to the commands you typically use to navigate file system paths.
The SQL Server PowerShell Hierarchy
Products whose data or object models can be represented in a hierarchy use Windows PowerShell providers to expose the hierarchies. The hierarchy is exposed by using a drive and path structure similar to what the Windows file system uses.
Each Windows PowerShell provider implements one or more drives. Each drive is the root node of a hierarchy of related objects. The SQL Server provider implements a SQLSERVER: drive. The provider also defines a set of primary folders for the SQLSERVER: drive. Each folder and its subfolders represent the set of objects that can be accessed by using a SQL Server management object model. When you are focused on a subfolder in a path that starts with one of these primary folders, you can use the methods from the associated object model to perform actions on the object that is represented by the node. The Windows PowerShell folders implemented by the SQL Server 2017 provider are listed in the following table:
|Folder||SQL Server object model namespace||Objects|
|Database objects, such as tables, views, and stored procedures.|
|Policy-based management objects, such as policies and facets.|
|Registered server objects, such as server groups and registered servers.|
||Microsoft.SqlServer.Management.Utility||Utility objects, such as managed instances of the Database Engine.|
||Microsoft.SqlServer.Management.DAC||Data-tier application objects such as DAC packages, and operations such as deploying a DAC.|
||Microsoft.SqlServer.Management.Collector||Data collector objects, such as collection sets and configuration stores.|
||Microsoft.SqlServer.Management.IntegrationServices||Integration Services objects such as projects, packages, and environments.|
||Microsoft.AnalysisServices||Analysis Services objects such as cubes, aggregations, and dimensions.|
For example, you can use the SQLSERVER:\SQL folder to start paths that can represent any object that is supported by the SMO object model. The leading part of a SQLSERVER:\SQL path is SQLSERVER:\SQL\ComputerName\InstanceName. The nodes after the instance name alternate between object collections (such as Databases or Views) and object names (such as AdventureWorks2012). Schemas are not represented as object classes. When you specify the node for a top-level object in a schema, such as a table or view, you must specify the object name in the format SchemaName.ObjectName.
The following example shows the path of the Vendor table in the Purchasing schema of the AdventureWorks2012 database in a default instance of the Database Engine on the local computer:

Collection nodes in a path are associated with a collection class in the associated object model. Object name nodes are associated with an object class in the associated object model, as in the following table:
