使用 BETWEEN 过滤 Table 但数据未显示

Question

我正在尝试使用组合框按月过滤我的 table，但每当我 select 十月时，即使我的数据库中的时间戳是十月，也没有任何显示。

这是我的代码：

String monthSelection = cbbMonthSearch.getSelectedItem().toString();
if (monthSelection == "Month") {
    System.out.println("month");
} else if (monthSelection == "October") {
    try {
        con = DriverManager.getConnection("jdbc:mysql://localhost/studentlogin", "root", "");
        //String sql = "SELECT * FROM studentregisterlogin WHERE TimeIn BETWEEN '2020-10-01 00:00:00' AND '2020-10-31 00:00:00' AND SSN=" +jftfSearch.getText();
        String sql = "SELECT * FROM studentregisterlogin WHERE TimeIn>='2020-10-01 01:00:00' AND TimeIn<='2020-10-31 23:59:59'";
        pst = con.prepareStatement(sql);
        pst.executeQuery();
        jtTableTime.setModel(DbUtils.resultSetToTableModel(rs));

    } catch (Exception e) {
        JOptionPane.showMessageDialog(null, e);
    }
} else if (monthSelection == "November") {
    System.out.println("november");
}

Answer 1

将 rs = 添加到 pst.executeQuery()；解决问题
