Procedures Append Method Example (VB)

The following code demonstrates how to use a Command object and the Procedures collection Append method to create a new procedure in the underlying data source.

' BeginCreateProcedureVB
Sub Main()
    On Error GoTo CreateProcedureError

    Dim cnn As New ADODB.Connection
    Dim cmd As New ADODB.Command
    Dim prm As ADODB.Parameter
    Dim cat As New ADOX.Catalog
    
    ' Open the Connection
    cnn.Open _
        "Provider='Microsoft.Jet.OLEDB.4.0';" & _
        "Data Source='c:\Program Files\Microsoft Office\" & _
        "Office\Samples\Northwind.mdb';"
    
    ' Create the parameterized command (Microsoft Jet specific)
    Set cmd.ActiveConnection = cnn
    cmd.CommandText = "PARAMETERS [CustId] Text;" & _
    "Select * From Customers Where CustomerId = [CustId]"
    
    ' Open the Catalog
    Set cat.ActiveConnection = cnn
    
    ' Create the new Procedure
    cat.Procedures.Append "CustomerById", cmd
    
    'Clean
    cnn.Close
    Set cat = Nothing
    Set cmd = Nothing
    Set cnn = Nothing
    Exit Sub
    
CreateProcedureError:
    Set cat = Nothing
    Set cmd = Nothing
    
    If Not cnn Is Nothing Then
        If cnn.State = adStateOpen Then cnn.Close
    End If
    Set cnn = Nothing
    
    If Err <> 0 Then
        MsgBox Err.Source & "-->" & Err.Description, , "Error"
    End If
End Sub
' EndCreateProcedureVB
