增加'max_allowed_pa​​cket'后mysql查询被截断

Question

我在c＃中有一个存储过程，我将值添加到然后执行：

        string query = "INSERT INTO equipment_parameter (parameter_group_name, version, operation_name, parameter_name, parameter_value, default, owner, date_created) VALUES(@parameter_group_name, @version, @operation_name, @parameter_name, @parameter_value, @default, @owner, @date_created)";    //stored procedure

        //open connection
        if (mySQLA.OpenConnection() == true)
        {
            //create command  
            MySqlCommand cmd = new MySqlCommand();
            cmd.Connection = mySQLA.getConnection();
            cmd.CommandText = query;
            cmd.Prepare();

            //string
            cmd.Parameters.AddWithValue("@parameter_group_name", eParam.ParameterGroupName);
            //int 
            cmd.Parameters.AddWithValue("@version", eParam.Version);
            //string
            cmd.Parameters.AddWithValue("@operation_name", eParam.OperationName);
            //string
            cmd.Parameters.AddWithValue("@parameter_name", eParam.ParameterName);
            //double
            cmd.Parameters.AddWithValue("@parameter_value", eParam.ParameterValue);
            //bool
            cmd.Parameters.AddWithValue("@default", eParam.Default);
            //string
            cmd.Parameters.AddWithValue("@owner", eParam.Owner);
            //DateTime
            cmd.Parameters.AddWithValue("@date_created", eParam.DateCreated);

            //Execute command
            try
            {
                rowsCreated = cmd.ExecuteNonQuery();      //returns number of rows affected
            }
            catch (MySqlException es)
            {
                MessageBox.Show(es.Message, "Equipment Parameter Query Error: ");
            }

当我运行这个程序时，它会尝试插入，然后我会捕获说明的异常：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'default, owner, date_created) VALUES('object1', 1, 'Op1', 'object1', 10.01, 1, '' at line 1

我正在尝试执行的查询将读取如下内容：

INSERT INTO equipment_parameter (parameter_group_name, version, operation_name, parameter_name, parameter_value, default, owner, date_created) VALUES('object', 1, 'Op1', 'object1', 10.01, false, 'James', '2013-10-30 09:00:54')

我已经将'max_allowed_pa​​cket'增加到500M并重新启动了服务器，尽管这没有效果。我可以增加其他缓冲区大小选项或可能是我的问题吗？

用我的脑袋沸腾后，我才意识到default是一个保守的词。因此，它必须被反击：

[...] parameter_value, `default`, owner, date_created) [...]
