This is the code I'm using to update an SQL database:

Public Sub main()

    Dim cnn As ADODB.Connection
    Dim rst As ADODB.Recordset

    Set cnn = New ADODB.Connection
    Set rst = New ADODB.Recordset

    cnn.Open "ConnectionName"
    rst.ActiveConnection = cnn
    rst.CursorLocation = adUseServer

    rst.Source = "Update Table ..."
    rst.Open

    Set rst = Nothing
    Set cnn = Nothing
End Sub

What I want to know is if and how I should deal with the rst object after opening it. Do I close it? When I try doing rst.Close, I get the error: "Operation is not allowed when the object is closed". The code works fine without rst.Close, I'm wondering if there are any dangers to not closing the object.
