我的錯誤？

Question

我想獲得實際創建的主鍵。 我需要立即爲另一個方法，但它會返回一個錯誤。 但它返回一個SQLE。我不知道我的錯誤。 我希望我給你enaugh信息。 （本的System.out.println（ID）是隻爲我檢查它是否返回正確的PrimaryKey）

CREATETABLE：

CREATE TABLE "MitarbeiterInfo" ("Vorname" TEXT, "Nachname" TEXT, "Geburtsdatum" CHAR, "Wohnadresse" TEXT, "Postleitzahl" TEXT, "Eintrittsdatum" CHAR, "Handynummer" TEXT, "Email" TEXT, "ID" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL) 

GuiClass：

public void actionPerformed(ActionEvent e) { 
      new Datenbank().mitarbeiterHinzufügen(
        textField.getText(),textField_1.getText(),textField_2.getText(),textField_3.getText(), 
        textField_4.getText(),textField_5.getText(),textField_6.getText(),textField_7.getText()); 
      refreshTable(); 
     } 

DatabaseClass：

public void mitarbeiterHinzufügen(String v, String n, String g, String w, String p, String e, String h, String email){ 
    conn=Datenbank.dbConnector(); 


    try { 
     String query="insert into MitarbeiterInfo (Vorname,Nachname,Geburtsdatum,Wohnadresse,Postleitzahl,Eintrittsdatum,Handynummer,Email,ID) values (?,?,?,?,?,?,?,?,?)"; 
     PreparedStatement pst=conn.prepareStatement(query); 
     pst.setString(1, v); 
     pst.setString(2, n); 
     pst.setString(3, g); 
     pst.setString(4, w); 
     pst.setString(5, p); 
     pst.setString(6, e); 
     pst.setString(7, h); 
     pst.setString(8, email); 

     pst.execute(); 

     String identitiy = "SELECT IDENTITY_VAL_LOCAL() FROM MitarbeiterInfo"; 
     ResultSet rs = pst.executeQuery(identitiy); 
     rs.next(); 
     int id = rs.getInt("1"); 
     System.out.println(id); 


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

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

Answer 1

嘗試

SELECT last_insert_rowid() FROM MitarbeiterInfo代替。

你得到的異常似乎暗示IDENTITY_VAL_LOCAL()不被SQLite支持。

Answer 2

java.sql.ResultSet中，以下方法的是爲getInt定義：

getInt(int columnIndex) 
getInt(String columnLabel) 

我發現問題，在下面的代碼行：

int id = rs.getInt("1"); 

你應該用一個獲得價值的選項：

int id = rs.getInt(1); 

或

int id = rs.getInt("Column_name");
