In SMO, a database is represented by the Database object.

It is not necessary to create a Database object to modify or remove it. The database can be referenced by using a collection.

Example

To use any code example that is provided, you will have to choose the programming environment, the programming template, and the programming language in which to create your application. For more information, see Create a Visual C# SMO Project in Visual Studio .NET.

Creating, Altering, and Removing a Database in Visual Basic

This code example creates a new database. Files and file groups are automatically created for the database.

'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()

{  
                //Connect to the local, default instance of SQL Server.   
                Server srv;  
                srv = new Server();  
                //Define a Database object variable by supplying the server and the database name arguments in the constructor.   
                Database db;  
                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();  
            }

Creating, Altering, and Removing a Database in PowerShell

This code example creates a new database. Files and file groups are automatically created for the database.

#Get a server object which corresponds to the default instance  
cd \sql\localhost\  
$srv = get-item default  
  
#Create a new database  
$db = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Database -argumentlist $srv, "Test_SMO_Database"  
$db.Create()  
  
#Reference the database and display the date when it was created.   
$db = $srv.Databases["Test_SMO_Database"]  
$db.CreateDate  
  
#Drop the database  
$db.Drop()
