'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")

'Display the current options for statistics.
Console.WriteLine("Automatically create statistics = " + _
db.AutoCreateStatisticsEnabled.ToString)
Console.WriteLine("Automatically update statistics = " + _
db.AutoUpdateStatisticsEnabled.ToString)

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")
Write-Host "Automatically create statistics =" $db.AutoCreateStatisticsEnabled
Write-Host "Automatically update statistics =" $db.AutoUpdateStatisticsEnabled
