asp.net - 拒绝执行 ExecuteNonQuery : Incorrect syntax near '('

Question

我正在尝试将数据插入我的数据库，但出现错误:

Incorrect syntax near '('.

这是我的代码:

string username = Session["Session"].ToString();

            con = new SqlConnection("Data Source=MICROSOF-58B8A5\\SQL_SERVER_R2;Initial Catalog=Daniel;Integrated Security=True");
            con.Open();

            string knowWhichOne = "SELECT ID FROM Users WHERE Username='" + UserOrGuest.Text + "'";

            SqlCommand comm = new SqlCommand(knowWhichOne, con);
            int userID = (Int32)comm.ExecuteScalar();

            knowWhichOne = "SELECT ClassID FROM Users WHERE Username='" + UserOrGuest.Text + "'";

            comm = new SqlCommand(knowWhichOne, con);
            int classID = (Int32)comm.ExecuteScalar();

            knowWhichOne = "SELECT SchoolID FROM Users WHERE Username='"+UserOrGuest.Text + "'";

            comm = new SqlCommand(knowWhichOne, con);
            int schoolID = (Int32)comm.ExecuteScalar();

            if (RadioWords.Checked == true)
            {
                 game = 1;
            }
            else
            {
                 game = 2;
            }


            string sqlqueryString = "INSERT INTO (GameID, UserID, LengthOfArray, NumberOfErrors, ClassID, SchoolID) VALUES (@GameID, @UserID, @LengthOfArray, @NumberOfErrors, @ClassID, @SchoolID)";

            SqlCommand commandquery = new SqlCommand(sqlqueryString, con);

            commandquery.Parameters.AddWithValue("GameID", game);
            commandquery.Parameters.AddWithValue("UserID", userID);
            commandquery.Parameters.AddWithValue("LengthOfArray", HowMany.Text);
            commandquery.Parameters.AddWithValue("NumberOfErrors", 0);
            commandquery.Parameters.AddWithValue("ClassID", classID);
            commandquery.Parameters.AddWithValue("SchoolID", schoolID);

            commandquery.ExecuteNonQuery();
            con.Close();

我在 Debug模式下运行它，它接受一切直到“ExecuteNonQuery();”行。

有人知道我做错了什么吗？

谢谢!

你这样做了:

INSERT INTO (GameID....

但应该这样做:

INSERT INTO tablename (GameID....
