        cmd.ExecuteNonQuery();
        return Convert.ToInt32(cmd.Parameters[0].Value, (IFormatProvider)CultureInfo.InvariantCulture);

    }

我收到错误

          cmd.Parameters.Add("abcd2", OracleDbType.Int32, logEntry.abcd2, ParameterDirection.Input);

logEntry.abcd2 的值为 0x000000000 并且我的表中的优先级不为空。如何解决这个错误？请帮忙 。任何线索都会有所帮助。
