我的代碼:SQL語法錯誤
try{ Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/lentele", "root", "");
String select = "SELECT * FROM darbuotojai WHERE 1";
String ID = infoID.getText();
String Vardas = infoV.getText();
String Pavardė = infoP.getText();
String Pareigos = infoPar.getSelectedItem().toString();
String Alga = infoAlg.getText();
String Premija = infoPre.getText();
String insert = "INSERT INTO `darbuotojai`(`ID`, `Vardas`, `Pavardė`, `Pareigos`, `Alga`, `Premija`) VALUES ('"+ID+"','"+Vardas+"','"+Pavardė+"','"+Pareigos+"','"+Alga+"','"+Premija+"',)";
stm.executeUpdate(insert);
JOptionPane.showMessageDialog(null, "Užklausa sėkminga");
infoID.setText("");
infoV.setText("");
infoP.setText("");
infoPar.setSelectedItem("");
infoAlg.setText("");
infoPre.setText("");
display();
} catch (Exception e) {JOptionPane.showMessageDialog(null, e.getMessage()); }
,我得到象這樣的錯誤:
you have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 1.
And ones more: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user ''@'localhost' to database 'lentele'.
請解釋這些問題在最簡單的方法初學者。 此代碼用於添加按鈕,這將有助於將信息插入到我的表中。
刪除最後一個','在''「+ Premija +」',' –
