Java 如何根据当前日期筛选记录？

我正在实现一个功能，我正在以字符串形式存储日期，并使用LocalDate函数以字符串形式获取当前日期，所以我想比较两个日期，我只想获取当前日期记录

未找到错误，但记录无法获取

  public ArrayList<Followup_Model> followup_reminder (ArrayList<Followup_Model> followup_Model_list) {
    if (followup_Model_list == null) {
        followup_Model_list = new ArrayList<>();
    }
    SQLiteDatabase sqLiteDatabase = this.getReadableDatabase();
    DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd");
    LocalDate localDate = LocalDate.now();
    String Today = dtf.format(localDate);
    Cursor followup_output = sqLiteDatabase.rawQuery("SELECT * FROM " + Table_Name_Followup +
            " WHERE CREATEDBY = '1' AND CHECKED = '1' AND STARTDATE = " + Today +
            " ORDER BY REMINDER ASC",null);

public ArrayList followup\u提醒（ArrayList followup\u Model\u列表）{
if（后续模型列表==null）{
followup_Model_list=new ArrayList（）；
}
SQLiteDatabase SQLiteDatabase=this.getReadableDatabase（）；
DateTimeFormatter dtf=模式的DateTimeFormatter.of（“yyyy/MM/dd”）；
LocalDate LocalDate=LocalDate.now（）；
String Today=dtf.format（localDate）；
Cursor followup\u output=sqLiteDatabase.rawQuery（“SELECT*FROM”+表名\u followup+
“其中CREATEDBY='1'和CHECKED='1'以及STARTDATE=“+Today+
“提醒ASC订购”，空）；

只需复制粘贴即可

public ArrayList<Followup_Model> followup_reminder (ArrayList<Followup_Model> 
 followup_Model_list) {
    if (followup_Model_list == null) {
        followup_Model_list = new ArrayList<>();
    }
    SQLiteDatabase sqLiteDatabase = this.getReadableDatabase();
    DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd");
    LocalDate localDate = LocalDate.now();
    String Today = dtf.format(localDate);
    Cursor followup_output = sqLiteDatabase.rawQuery("SELECT * FROM " + Table_Name_Followup +
            " WHERE CREATEDBY = '1' AND CHECKED = '1' AND STARTDATE = '" + Today + "'" +
            " ORDER BY REMINDER ASC",null);

public ArrayList followup\u提醒（ArrayList
跟进（型号列表）{
if（后续模型列表==null）{
followup_Model_list=new ArrayList（）；
}
SQLiteDatabase SQLiteDatabase=this.getReadableDatabase（）；
DateTimeFormatter dtf=模式的DateTimeFormatter.of（“yyyy/MM/dd”）；
LocalDate LocalDate=LocalDate.now（）；
String Today=dtf.format（localDate）；
Cursor followup\u output=sqLiteDatabase.rawQuery（“SELECT*FROM”+表名\u followup+
“其中CREATEDBY='1'和CHECKED='1'以及STARTDATE='”+Today+“”+
“提醒ASC订购”，空）；

尝试在日期周围加上单字quotes@ScaryWombat日期不是固定的，它正在变为变量。我如何将它放在单引号

和STARTDATE='“+Today+'”++

中，或者更好地使用PreparedStatement和paramaters
