vb.net Oracle Insert with parameters (ORA-00936: missing expression)

Question

i would like to use oracle parameters to insert data into the oracle db. i do the same in with sql server and it works fine. But with oracle i always get the ORA-00936: missing expression exception on the oCom.ExecuteNonQuery.

thanks for answers.. here is my vb.net code.

Using connOMS = New OracleConnection(connectionStringOMS)
Try
    connOMS.Open()

    Dim cmdstr As String = "INSERT INTO ARCHIVE_FEEDBACK(STATUS) VALUES(@STATUS)"

    Using Ocom As OracleCommand = New OracleCommand(cmdstr, connOMS)
        Dim p As OracleParameter
        p = New OracleParameter()
        p.Direction = ParameterDirection.InputOutput
        p.OracleDbType = OracleDbType.Varchar2
        p.ParameterName = "@STATUS"
        p.Value = "A"
        Ocom.Parameters.Add(p)

        Dim iRet As Integer = Ocom.ExecuteNonQuery
        If iRet > 0 Then
            Return True
        Else
            Return False
        End If
    End Using

    Catch ex As ApplicationException
        '...
    Catch orex As OracleException
        '...
    Finally

End Try

End Using

For Oracle, you need to use a colon (:) rather than the "at" sign (@) to indicate a parameter:

Dim cmdstr As String = "INSERT INTO ARCHIVE_FEEDBACK(STATUS) VALUES(:STATUS)"

and later on...

p.ParameterName = ":STATUS"
