Hi

I trying to call a procedure passing only parameter, but return me error when stat.
The parameter is value of DTpickcer in format AAAAMM . plese see:

     Set cmd = New ADODB.Command
      nAno_mes = Format(dtpAnoMes.Value, "yyyymm")
      
      Screen.MousePointer = vbHourglass
      With cmd
             .ActiveConnection = cn
             .CommandText = "PROCEDURE_ONE"
             .CommandType = adCmdStoredProc
            .Parameters.Append .CreateParameter("@P_ANO_MES", adNumeric, adParamInput, nAno_mes)
            .Execute
      End With

mY Procedure in oracle begin as:

create or replace procedure PROCEDURE_ONE ( P_ANO_MES in number ) is

Error in exception VB

 ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'PROCEDURE_ONE'
