示例

Visual Basic

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Modify a property using the Databases, Tables, and Columns collections to reference a column.
srv.Databases("AdventureWorks2012").Tables("Person", "Person").Columns("ModifiedDate").Nullable = True
'Call the Alter method to make the change on the instance of SQL Server.
srv.Databases("AdventureWorks2012").Tables("Person", "Person").Columns("ModifiedDate").Alter()

PowerShell

$srv = new-object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = $srv.Databases.Item("AdventureWorks2012")
$tb = $db.Tables.Item("Person", "Person")
$col = $tb.Columns.Item("LastName")
$col.Nullable = $TRUE
$col.Alter()
