在Eclipse中執行SQL查詢時出錯

我想用下面的代碼更新一個表，並將ID用作主鍵，但只發生下面的錯誤。在Eclipse中執行SQL查詢時出錯

那是什麼香港專業教育學院在我的actionPerformed：我PrimaryKey的是「ID」

public void actionPerformed(ActionEvent e) { 
      try { 
       String query="Update MitarbeiterInfo set " 
         + "Vorname='"+textField.getText()+"' ," 
         + "Nachname='"+textField_1.getText()+"' ," 
         + "Geburtsdatum='"+textField_2.getText()+"' ," 
         + "Wohnadresse='"+textField_3.getText()+"' ," 
         + "Postleitzahl='"+textField_4.getText()+"'," 
         + "Eintrittsdatum='"+textField_5.getText()+"'," 
         + "Handynummer='"+textField_6.getText()+"'," 
         + "Email='"+textField_7.getText()+"' " 
         + "ID='"+fieldID.getText()+"' " 
         + "where ID='"+fieldID.getText()+"' "; 

       PreparedStatement pst=connection.prepareStatement(query); 


       pst.execute(); 

       JOptionPane.showMessageDialog(null, "Mitarbeiter aktualisiert"); 

       pst.close(); 
      } catch (Exception b) { 
       b.printStackTrace(); 
      } 
     }

的錯誤發生：

您更新ID列（你不真正需要做的）前錯過了上一個逗號：

+ "Email='"+textField_7.getText()+"', " 
+ "ID='"+fieldID.getText()+"' " 
+ "where ID='"+fieldID.getText()+"' ";

而且你不需要在這種情況下，使用PreparedStatement（無參數綁定到準備好的查詢）。只需使用一個Statement對象：

Statement statement = connection.createStatement(); 
statement.executeUpdate(query);

謝謝你你幫我:) – rubine

刪除

+ "ID='"+fieldID.getText()+"' "

你不需要它，當你有

"where ID='"+fieldID.getText()+"' ";

它僅會自動更新到相同的價值。
