This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.

The Database class represents databases, either system or user-defined, on the instance of SQL Server. The Server class is the parent of the Database class.

By using the Database class, you can do the following:

  • Create a new database or drop and existing database.

  • Register the database in the Active Directory directory service.

  • Reference database objects in collections, such as tables, users, and triggers.

  • Set up database mirroring.

  • Create a master database key.

  • Set up a full-text search catalog.

  • Check data, allocations, catalogs, and tables.

  • Issue a checkpoint.

  • Grant, revoke, and deny permissions to users on the database.

  • Run Transact-SQL statements.

  • Enumerate database information, such as locks or object permissions.

  • Remove the backup history.

  • Monitor the number of transactions.

  • Set the database offline or online.

  • Change the owner of the database.

  • Update statistics.

  • Shrink the database.

  • Truncate the log.

  • Script the database.

To get Database object properties, users can be a member of the public fixed server role.

To set Database object properties and run the Alter method, users must have ALTER permission on the database, or be a member of the db_owner fixed database role.

To create a database, users must have CREATE DATABASE, CREATE ANY DATABASE, or ALTER ANY DATABASE permission on the parent server.

To drop a database, users must have CONTROL permission on the database, or be a member of the db_owner fixed database role.

To grant, revoke, or deny other users permission on the database, users must have CONTROL permission on the database or be a member of the db_owner fixed database role.


'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Define a Database object variable by supplying the server and the database name arguments in the constructor.
Dim db As Database
db = New Database(srv, "Test_SMO_Database")
'Create the database on the instance of SQL Server.
db.Create()
'Reference the database and display the date when it was created.
db = srv.Databases("Test_SMO_Database")
Console.WriteLine(db.CreateDate)
'Remove the database.
db.Drop()

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
