Question

我决定添加＆＃34;添加＆＃34;按钮，将员工记录添加到我的Access数据库，员工表。

每当我点击＆＃34;添加＆＃34;按钮，出现错误消息＆＃34; INSERT INTO语句中的语法错误＆＃34;。有人可以帮忙吗？我的编码有问题吗？因为我确实非常关注这个视频，即使在视频中，这个人成功地成功了＃34; Saved＆＃34;记录到数据库，我不断收到错误。

conn = Connect.ConnectDB();
        String sql = "insert into Employee ("
                +"Employee ID,"
                +"Employee Name,"
                +"Employee NICN,"
                +"Employee Gender,"
                +"Employee Contact Number,"
                +"Employee Department)"
                +"values("+txteid.getText()+ ",'"+txtename.getText()+"','"+txtenicn.getText()+"','"+txtegender.getText()+"','"+txtecnumber.getText()+"','"
                +txtedept.getText()+"')";
        try{
            pst = conn.prepareStatement(sql);
            pst.execute();
            JOptionPane.showMessageDialog(null, "Added");

        }catch(Exception e){
            JOptionPane.showMessageDialog(null, e);
        }

您使用预准备语句，因此您必须使用参数

   conn = getConnection();
   String sql = "insert into Employee ("
                +"Employee ID,"
                +"Employee Name,"
                +"Employee NICN,"
                +"Employee Gender,"
                +"Employee Contact Number,"
                +"Employee Department)"
                +"values(?,?,?,?,?,?)";

然后设置参数：

      pstmt.setInt(1, txteid.getText()); // set input parameter 1
      pstmt.setString(2, txtename.getText()); // set input parameter 2
 ...
      pstmt.executeUpdate(); // execute insert statement

INSERT INTO语句中的语法错误
