嗨，我目前正在開發一個應用程序來維護某個工廠的股票，我無法將訂單插入數據庫..我嘗試修復這個我自己的，但我不能這樣如果任何人可以幫助我很高興。Java MySQLSyntaxErrorException
因此，這裏是我的錯誤

我的代碼是
for (int i = 0; i < jTable1.getRowCount(); i++) {
String $Name = "", $Color = "", $Leather = "", $s38 = "", $s39 = "", $s40 = "", $s41 = "", $s42 = "", $s43 = "", $s44 = "", $s45 = "", $s46 = "", Total = "", ItemId = "";
$Name += jTable1.getValueAt(i, 0)+"";
$Color += jTable1.getValueAt(i, 1)+"";
$Leather += jTable1.getValueAt(i, 2)+"";
$s38 += jTable1.getValueAt(i, 3)+"";
$s39 += jTable1.getValueAt(i, 4)+"";
$s40 += jTable1.getValueAt(i, 5)+"";
$s41 += jTable1.getValueAt(i, 6)+"";
$s42 += jTable1.getValueAt(i, 7)+"";
$s43 += jTable1.getValueAt(i, 8)+"";
$s44 += jTable1.getValueAt(i, 9)+"";
$s45 += jTable1.getValueAt(i, 10)+"";
$s46 += jTable1.getValueAt(i, 11)+"";
Total += jTable1.getValueAt(i, 12)+"";
ItemId += jTable1.getValueAt(i, 13)+"";
DB.Save_Update_Delete("insert into order (Add_Order_PID,Customer_idCustomer,Items_idItems,User_idUser,Color,Leather,s38,s39,s40,s41,s42,s43,s44,s45,s46,Total) values ('"+pid+"','"+Integer.parseInt(customerID.getText())+"','"+Integer.parseInt(ItemId)+"','"+Integer.parseInt(UserID.getText())+"','"+$Color+"','"+$Leather+"','"+$s38+"','"+$s39+"','"+$s40+"','"+$s41+"','"+$s42+"','"+$s43+"','"+$s44+"','"+$s45+"','"+$s46+"','"+Total+"')");
}
使用準備好的語句 –
詳細說明「使用準備好的語句」：準備好的語句更有效，並且對SQL注入攻擊是安全的，而連接的SQL字符串（在您使用時）不是。 –
@FrankSchmitt是他們在PreparedStatement中的任何方式來添加where條款下的條件，或者我需要首先確定所有條件，然後單步執行PreparedStatement。對不起，這是關閉的話題。 – guptakvgaurav
