示例

VB

'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")

'Define a FileGroup object called SECONDARY on the database.
Dim fg1 As FileGroup
fg1 = New FileGroup(db, "FILEGROUP2")

'Call the Create method to create the file group on the 
'instance of SQL Server.
fg1.Create()

'Define a DataFile object on the file group and set 
'the FileName property.
Dim df1 As DataFile
df1 = New DataFile(fg1, "newfile")
df1.FileName = _
"c:\Program Files\Microsoft SQL Server\MSSQL10\MSSQL\DATA\newfile.ndf"

'Call the Create method to create the data file on the 
'instance of SQL Server.
df1.Create()

'Set the new default file group for the database.
db.SetDefaultFileGroup(fg1.Name)

PowerShell

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

$fg1 = new-object Microsoft.SqlServer.Management.Smo.FileGroup($db, "FILEGROUP2")
$fg1.Create()

$df1 = new-object Microsoft.SqlServer.Management.Smo.DataFile($fg1, "newfile")
$df1.FileName = "c:\Program Files\Microsoft SQL Server\MSSQL10\MSSQL\DATA\newfile.ndf"

$df1.Create()

$db.SetDefaultFileGroup($fg1.Name)
