This example uses the Append and CreateParameter methods to execute a stored procedure with input parameters.

Public Sub AppendX()

   Dim cnn1 As ADODB.Connection
   Dim cmdByRoyalty As ADODB.Command
   Dim prmByRoyalty As ADODB.Parameter
   Dim rstByRoyalty As ADODB.Recordset
   Dim rstAuthors As ADODB.Recordset
   Dim intRoyalty As Integer
   Dim strAuthorID As String
   Dim strCnn As String

   'Open the connection.
   Set cnn1 = New ADODB.Connection
   strCnn = "Provider=sqloledb;"&_
      "Data Source=srv;Initial Catalog=pubs;User Id=sa;Password=;"
   cnn1.Open strCnn
   cnn1.CursorLocation = adUseClient
      
   'Open the command object with a single parameter.
   Set cmdByRoyalty = New ADODB.Command
   cmdByRoyalty.CommandText = "byroyalty"
   cmdByRoyalty.CommandType = adCmdStoredProc
   
   'Get parameter values ​​and append parameters.
   intRoyalty = Trim(InputBox("Enter royalty:"))
   Set prmByRoyalty = cmdByRoyalty.CreateParameter("percentage", _
      adInteger, adParamInput)
   cmdByRoyalty.Parameters.Append prmByRoyalty
   prmByRoyalty.Value = intRoyalty

   'Create a record set by executing the command.
   Set cmdByRoyalty.ActiveConnection = cnn1
   Set rstByRoyalty = cmdByRoyalty.Execute
   
   'Open the Authors table to get the author's name for display.
   Set rstAuthors = New ADODB.Recordset
   rstAuthors.Open "authors", cnn1,,, adCmdTable
   
   'Print the current data in the record set and add the author's name from the Authors table.
   Debug.Print "Authors with "&intRoyalty&" percent royalty"
   Do While Not rstByRoyalty.EOF
      strAuthorID = rstByRoyalty!au_id
      Debug.Print ""&rstByRoyalty!au_id&", ";
      rstAuthors.Filter = "au_id ='"&strAuthorID&"'"
      Debug.Print rstAuthors!au_fname&""&rstAuthors!au_lname
      rstByRoyalty.MoveNext
   Loop

   rstByRoyalty.Close
   rstAuthors.Close
   cnn1.Close

End Sub
