Problem with C # MySqlParameter

Question

(int) faultsGroup is 0 or 1, but I always get this error: the column "FaultGroup" cannot be zero

Does anyone tell me why? The syntax looks fine.

MySqlCommand cmdAdd = new MySqlCommand("INSERT INTO Faults (" +
        "  FaultGroup, Text, Date, IP" +
        ") VALUES (" +
        "  @FaultGroup, @Text, @Date, @IP" +
        ")", conn);

MySqlParameter paramFaultGroup = new MySqlParameter("@FaultGroup", MySqlDbType.Int32);
FaultsGroup faultsGroup = (FaultsGroup) Enum.Parse(typeof (FaultsGroup), myFault.FaultGroup);
paramFaultGroup.Value = (int) faultsGroup;
cmdAdd.Parameters.Add(paramFaultGroup);

cmdAdd.ExecuteNonQuery();

I have not used MySql for about 6 months (fortunately, I switched to Sql Server), but try changing my @ characters for?, As if the memory serves that the correct agreement with MySql, like this:

MySqlCommand cmdAdd = new MySqlCommand(
       "INSERT INTO Faults (FaultGroup, Text, Date, IP)"
       + " VALUES (?FaultGroup, ?Text, ?Date, ?IP)",
       conn);

MySqlParameter paramFaultGroup = new MySqlParameter("?FaultGroup", MySqlDbType.Int32);
FaultsGroup faultsGroup = (FaultsGroup) Enum.Parse(typeof (FaultsGroup), myFault.FaultGroup);
paramFaultGroup.Value = (int) faultsGroup;
cmdAdd.Parameters.Add(paramFaultGroup);

cmdAdd.ExecuteNonQuery();
