什么'；是什么导致了这个MySql.Data.MySqlClient.MySqlException？C#

我查看代码已有一段时间了，在cmd.ExecuteNonQuery（）上看不到任何可能导致以下错误的内容：

MySql.Data.dll其他信息中出现“MySql.Data.MySqlClient.MySqlException”类型的未处理异常：您的SQL语法有错误；请查看与MySQL服务器版本对应的手册，以获取第1行“”附近要使用的正确语法

这是我的代码：

public void InsertReservation(Reservation reservation)
{ //To counter the unavailable Auto Increment in the database
    int ReservationID = 0;
    string query = "SELECT max(ReservationID) FROM Reservation";

    if (this.OpenConnection())
    {
    MySqlCommand cmd = new MySqlCommand(query, connection);
    ReservationID = (Int32)cmd.ExecuteScalar();
    CloseConnection();
    }

    ReservationID++;
    string query2 = "INSERT INTO `Reservation`(`ReservationID`, `CarID`, `CustomerID`, `Startdate`, `Enddate`, `Confirmed`, `Kilometres`, `Pickupcity`, `Pickupstreetname`, `Pickupstreetnumber`, `Pickupstreetnumbersuffix`, `Paid`, `Comment`) VALUES(@reservationid,@carid,@customerid,@startdate,@enddate,@confirmed,@Kilometres,@pickupcity,@pickupstreetname,@pickupnumber,@pickupnumbersuffix,@paid,@comment";
    if (this.OpenConnection())
    {
        int convertCofnfirmedToInt;
        int convertPaidtoInt;
        MySqlCommand cmd = new MySqlCommand(query2, connection);
        cmd.Parameters.AddWithValue("@reservationid", ReservationID);
        cmd.Parameters.AddWithValue("@carid", reservation.carID);
        cmd.Parameters.AddWithValue("@customerid", reservation.customerID);
        cmd.Parameters.AddWithValue("@startdate", reservation.startdate);
        cmd.Parameters.AddWithValue("@enddate", reservation.enddate);
        cmd.Parameters.AddWithValue("@confirmed", reservation.);
        cmd.Parameters.AddWithValue("@Kilometres", reservation.kilometres);
        cmd.Parameters.AddWithValue("@pickupcity", reservation.pickupcity);
        cmd.Parameters.AddWithValue("@pickupstreetname", reservation.pickupstreetname);
        cmd.Parameters.AddWithValue("@pickupnumber", reservation.pickupstreetnumber);
        cmd.Parameters.AddWithValue("@pickupnumbersuffix", reservation.pickupstreetnumbersuffix);
        cmd.Parameters.AddWithValue("@paid", paidbool);
        cmd.Parameters.AddWithValue("@comment", reservation.comment);


        cmd.ExecuteNonQuery();
        this.CloseConnection();
    }

}

如果有人能帮我，那就太好了

在sql的末尾添加右括号

）

插入

：

string query2 = "INSERT INTO `Reservation`(`ReservationID`, `CarID`, `CustomerID`, `Startdate`, `Enddate`, `Confirmed`, `Kilometres`, `Pickupcity`, `Pickupstreetname`, `Pickupstreetnumber`, `Pickupstreetnumbersuffix`, `Paid`, `Comment`) VALUES(@reservationid,@carid,@customerid,@startdate,@enddate,@confirmed,@Kilometres,@pickupcity,@pickupstreetname,@pickupnumber,@pickupnumbersuffix,@paid,@comment)";
