我的.mdb数据库中有一个表。我想在此表中插入日期。所以我为此写了这段代码

public void main(String[] args) {
        // TODO Auto-generated method stub

        PreparedStatement state;
        Connection connect;
        DateFormat dateFormat=new SimpleDateFormat("dd/MM/yyyy");
        Calendar cal=Calendar.getInstance();
        String date=dateFormat.format(cal.getTime());
        System.out.println(date);
        try {
            connect = DriverManager.getConnection("jdbc:ucanaccess://C:/Users/FTK1187/Desktop/eArchiveMaster.mdb","FTEC198","");
            String sql="INSERT INTO LastUpdated (LastUpdatedDate) VALUES (#"+date+"#)"; 
            state=connect.prepareStatement(sql);
            state.execute();
            state.close();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }

这给了我这个错误

日期格式是我数据库中的一般日期。当我这样做的时候

System.out.println(date);

它给了我想要的东西,但是当我想在数据库中插入时出现错误。我不知道如何解决。

答案 0 :(得分:0)

无需使用SimpleDateFormatCalendar。要插入日期,我们可以简单地使用

String sql = "INSERT INTO LastUpdated (LastUpdatedDate) VALUES (?)";
state = connect.prepareStatement(sql);
state.setDate(1, java.sql.Date.valueOf(LocalDate.now()));
state.execute();
state.close();

或者,因为我们要插入当前日期,所以我们可以这样做

String sql = "INSERT INTO LastUpdated (LastUpdatedDate) VALUES (DATE())";
state = connect.prepareStatement(sql);
state.execute();
state.close();
