要使用Android AlarmManager与SQL进行操作，你可以按照以下步骤进行：

1. 创建一个数据库帮助类（DbHelper.java）来管理数据库的创建和版本控制：

public class DbHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "alarms_db";
    private static final int DATABASE_VERSION = 1;

    private static final String TABLE_ALARMS = "alarms";
    private static final String COLUMN_ID = "_id";
    private static final String COLUMN_TITLE = "title";
    private static final String COLUMN_TIME = "time";

    public DbHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        String CREATE_ALARMS_TABLE = "CREATE TABLE " + TABLE_ALARMS +
                "(" +
                COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
                COLUMN_TITLE + " TEXT," +
                COLUMN_TIME + " INTEGER" +
                ")";
        db.execSQL(CREATE_ALARMS_TABLE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_ALARMS);
        onCreate(db);
    }
}

2. 创建一个Alarm类（Alarm.java）来表示一个闹钟对象：

public class Alarm {
    private int id;
    private String title;
    private long time;

    public Alarm() {
    }

    public Alarm(int id, String title, long time) {
        this.id = id;
        this.title = title;
        this.time = time;
    }

    // Getters and setters

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public long getTime() {
        return time;
    }

    public void setTime(long time) {
        this.time = time;
    }
}

3. 创建一个AlarmDataSource类（AlarmDataSource.java）来处理数据库的CRUD操作：

public class AlarmDataSource {

    private SQLiteDatabase database;
    private DbHelper dbHelper;

    public AlarmDataSource(Context context) {
        dbHelper = new DbHelper(context);
    }

    public void open() throws SQLException {
        database = dbHelper.getWritableDatabase();
    }

    public void close() {
        dbHelper.close();
    }

    public void createAlarm(String title, long time) {
        ContentValues values = new ContentValues();
        values.put(DbHelper.COLUMN_TITLE, title);
        values.put(DbHelper.COLUMN_TIME, time);
        database.insert(DbHelper.TABLE_ALARMS, null, values);
    }

    public List getAllAlarms() {
        List alarms = new ArrayList<>();

        Cursor cursor = database.query(DbHelper.TABLE_ALARMS, null, null, null, null, null, null);
        cursor.moveToFirst();
        while (!cursor.isAfterLast()) {
            int id = cursor.getInt(cursor.getColumnIndex(DbHelper.COLUMN_ID));
            String title = cursor.getString(cursor.getColumnIndex(DbHelper.COLUMN_TITLE));
            long time = cursor.getLong(cursor.getColumnIndex(DbHelper.COLUMN_TIME));

            Alarm alarm = new Alarm(id, title, time);
            alarms.add(alarm);

            cursor.moveToNext();
        }
        cursor.close();

        return alarms;
    }

    public void deleteAlarm(int id) {
        database.delete(DbHelper.TABLE_ALARMS, DbHelper.COLUMN_ID + " = " + id, null);
    }
}

4. 在你的Activity中使用AlarmDataSource类来操作数据库，并通过AlarmManager设置闹钟：

public class MainActivity extends AppCompatActivity {

    private AlarmDataSource dataSource;
    private AlarmManager alarmManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        dataSource = new AlarmDataSource(this);
        dataSource.open();

        alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        // 创建闹钟
        dataSource.createAlarm("闹钟1", System.currentTimeMillis() + 10000);

        // 获取所有闹钟
        List alarms = dataSource.getAllAlarms();

        for (Alarm alarm : alarms) {
            // 设置闹钟
            Intent intent = new Intent(this, AlarmReceiver.class);
            intent.putExtra("alarm_title", alarm.getTitle());
            PendingIntent pendingIntent = PendingIntent.getBroadcast(this, alarm.getId(), intent, 0);
            alarmManager.set(AlarmManager.RTC_WAKEUP, alarm.getTime(), pendingIntent);
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        dataSource.close();
    }
}

5. 创建
