MySQL -> 你的 SQL 语法错误我该如何解决

Question

MySql.Data.MySqlClient.MySqlException: '您的 SQL 语法有误；查看与您的 MySQL 服务器版本相对应的手册，了解在 'not=41, durum='BASARISIZ' Where id=2' at line 1'

附近使用的正确语法

    int i = 0;
    private void button2_Click(object sender, EventArgs e)
    {
        int not = Convert.ToInt16(comboBox5.Text) + Convert.ToInt16(comboBox3.Text) + Convert.ToInt16(comboBox4.Text) + Convert.ToInt16(comboBox6.Text) + Convert.ToInt16(comboBox7.Text) + Convert.ToInt16(comboBox8.Text) + Convert.ToInt16(comboBox9.Text) + Convert.ToInt16(comboBox10.Text) + Convert.ToInt16(comboBox11.Text) + Convert.ToInt16(comboBox12.Text) + Convert.ToInt16(comboBox13.Text) + Convert.ToInt16(comboBox14.Text) + Convert.ToInt16(comboBox15.Text) + Convert.ToInt16(comboBox16.Text) + Convert.ToInt16(comboBox17.Text) + Convert.ToInt16(comboBox18.Text) + Convert.ToInt16(comboBox19.Text) + Convert.ToInt16(comboBox20.Text) + Convert.ToInt16(comboBox21.Text);


        conn.Open();
        string update = "Update ogrenci Set not=@not, durum=@durum Where id=@id";
        cmd = new MySqlCommand(update, conn);

        cmd.Parameters.AddWithValue("@not", not);
        cmd.Parameters.AddWithValue("@durum", comboBox22.Text);
        cmd.Parameters.AddWithValue("@id", dataGridView1.Rows[i].Cells[0].Value);

        cmd.ExecuteNonQuery();

        MessageBox.Show("Başarıyla Güncellendi.");

        conn.Close();

        getOgrenci();
    }
    private void dataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
    {
        i = e.RowIndex;
        textBox1.Text = dataGridView1.Rows[i].Cells[2].Value.ToString();
        textBox4.Text = dataGridView1.Rows[i].Cells[3].Value.ToString();
        textBox2.Text = dataGridView1.Rows[i].Cells[6].Value.ToString();
    }

这是我的代码，所以我不明白为什么我会收到语法错误，而我没有任何语法问题。
