# Clustered Property Example (VB)
This example demonstrates the [Clustered](../../../ado/reference/adox-api/clustered-property-adox.md) property of an [Index](../../../ado/reference/adox-api/index-object-adox.md). Note that Microsoft Jet databases do not support clustered indexes, so this example will return **False** for the **Clustered** property of all indexes in the **Northwind** database.  
  
```  
' BeginClusteredVB  
Sub Main()  
    On Error GoTo ClusteredXError  
  
    Dim cnn As New ADODB.Connection  
    Dim cat As New ADOX.Catalog  
    Dim tblLoop As ADOX.Table  
    Dim idxLoop As ADOX.Index  
    Dim strCnn As String  
  
    strCnn = "Provider='SQLOLEDB';Data Source='MySqlServer';Initial Catalog='pubs';" & _  
        "Integrated Security='SSPI';"  
    ' Connect to the catalog.  
    cnn.Open strCnn  
    cat.ActiveConnection = cnn  
  
    ' Enumerate the tables.  
    For Each tblLoop In cat.Tables  
        'Enumerate the indexes.  
        For Each idxLoop In tblLoop.Indexes  
            Debug.Print tblLoop.Name & " " & _  
                idxLoop.Name & " " & idxLoop.Clustered  
        Next idxLoop  
    Next tblLoop  
  
    'Clean up.  
    cnn.Close  
    Set cat = Nothing  
    Set cnn = Nothing
