注释

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 an existing database.

• Register the database in the Active 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.

Thread Safety

此类型的任何公共静态（Microsoft Visual Basic 中的 Shared）成员在多线程操作中是安全的。但不保证所有实例成员都是线程安全的。

示例

VB

'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()

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database($srv, "Test_SMO_Database")
$db.Create()
Write-Host $db.CreateDate
$db.Drop()

线程安全

此类型的任何公共 static（在 Visual Basic 中为 Shared） 成员都是线程安全的。不保证所有实例成员都是线程安全的。
