Hinweise

You can use the Shrink method to reduce the size of the files that make up the database manually. The data is stored more densely and unused pages are removed. Alternatively, you can shrink the database automatically at intervals by setting the AutoShrink option.

Beispiele

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")

'Shrink the database without truncating the log.
db.Shrink(20, ShrinkMethod.NoTruncate)

'Truncate the log.
db.TruncateLog()

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")

$db.Shrink(20, [Microsoft.SqlServer.Management.Smo.ShrinkMethod]'NoTruncate')

$db.TruncateLog()
