データベースの行をdataGridViewの行で更新する方法C＃

Question

データベースの行をdataGridView1の行で更新するにはどうすればいいですか？

それはこのエラーを示しています。助けを

 private void button2_Click(object sender, EventArgs e) 
    { 
     foreach (DataGridViewRow dr in dataGridView1.Rows) 
     { 
      string constring = "Data Source = localhost; port = 3306; username = root; password = 0159"; 
      string Query = " Update TopShineDB.Table1 (Time, CarColorNumber, Interior, Exterior, CPlastic, MPlastic, SPlastic, PlasticB, WashExt, WashEng, WashTrunk, WashSeats, SeatsRmv, SeatsFit, Notes) VALUES ('" + dr.Cells[0] + "','" + dr.Cells[1] + "','" + dr.Cells[2] + "','" + dr.Cells[3] + "','" + dr.Cells[4] + "','" + dr.Cells[5] + "','" + dr.Cells[6] + "','" + dr.Cells[7] + "','" + dr.Cells[8] + "','" + dr.Cells[9] + "','" + dr.Cells[10] + "','" + dr.Cells[11] + "','" + dr.Cells[12] + "','" + dr.Cells[13] + "','" + dr.Cells[14] + "')"; 
      MySqlConnection conn = new MySqlConnection(constring); 
      MySqlCommand command = new MySqlCommand(Query, conn); 
      MySqlDataReader myReader; 

      try 
      { 
       conn.Open(); 
       myReader = command.ExecuteReader(); 
       MessageBox.Show("Table Successfully Updated"); 
       while (myReader.Read()) 
       { 

       } 
      } 
      catch (Exception ex) 
      { 
       MessageBox.Show(ex.Message); 
      } 
     } 
    } 

感謝：

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 '(Time, CarColorNumber, Interior, Exterior, CPlastic,...) 

が、これは私がこれまで持っているコードです。

Answer 1

string Query = "TopShineDB.Table1（時間、CarColorNumber、内部、外部、CPlastic、MPlastic、SPLastic、PlasticB、WashExt、WashEng、WashTrunk、WashSeats、SeatsRmv、SeatsFit、Notes）VALUES（ '+ dr。セル[0] + "'、" + dr.Cells [1] + "'、" "+ dr.Cells [2] +" '、 "" + dr.Cells [3] + "'、 dr.Cells [5] + "'、+" dr.Cells [6] + "'、" "+ dr.Cells [7] +" '、 "+ dr.Cells [8] +" "、+" dr.Cells [9] + "'、" + dr.Cells [10] + "'、 '+ "dr.Cells [12] +"'、+ "dr.Cells [13] +" '、 "" + dr.Cells [14] + "'）";

上記のSQLは、有効な更新ステートメントではありません。..正しいUPDATE構文は次のようになります -

UPDATE TopShineDB.Table1 
SET Time = '" + dr.Cells[0] + "', 
Notes = '"+ dr.Cells[14] + "' 
WHERE Table1ID = ID from the grid 

は私を知ってみましょうそれはまさに
