How to delete records from another table?

I have a database and tables of events and time table. I have linked events with time tables. Event has time table key column.

Now I want to delete a time table and when the time table gets deleted the events referenced to respective time table should get delete.

How to do this?

My current delete query is this to delete the table.

public void deleteTable(TimeTable timeTable) {
    SQLiteDatabase db = this.getWritableDatabase();
    db.delete(TABLE_TIME_TABLE, KEY_TIME_TABLE_ID + " = ?",
            new String[]{String.valueOf(timeTable.getId())});
    db.close();
}

Database helper

    public class DatabaseHelper extends SQLiteOpenHelper {



    private static final String TABLE_TIME_TABLE = "timetables";
    private static final String KEY_TABLE_TITLE = "tabletitle";
    private static final String KEY_TIME_TABLE_ID = "timetableid";
    private static final String KEY_TABLE_COLOR = "tablecolor";
    private static final String KEY_STATUS = "status";


    private static final String TABLE_EVENTS = "event";
    private static final String KEY_ID = "id";
    private static final String KEY_TITLE = "title";
    private static final String KEY_START_HOURS = "starthours";
    private static final String KEY_START_MINS = "startmins";
    private static final String KEY_END_HOURS = "endhours";
    private static final String KEY_END_MINS = "endmins";

    private static final String KEY_FROM_DATE = "datefrom";
    private static final String KEY_TO_DATE = "dateto";
    private static final String KEY_LOCATION = "location";
    private static final String KEY_DAY_OF_WEEK = "dayofweek";
    private static final String KEY_NOTIFICATION_TIME = "notification";

    private static final String KEY_COLOR = "color";


    private Context context;

    public DatabaseHelper(Context context) {
        super(context, Constants.DATABASE_NAME, null, Constants.DATABASE_VERSION);
        //3rd argument to be passed is CursorFactory instance
        this.context = context;
    }

    // Creating Tables
    @Override
    public void onCreate(SQLiteDatabase db) {


        createTable(db);

    }

    public void createDatabase(){
        context.deleteDatabase(Constants.DATABASE_NAME + ".db");
        SQLiteDatabase db = this.getReadableDatabase();
    }


    public void createTable(SQLiteDatabase db){
        String CREATE_EVENTS_TABLE = "CREATE TABLE " + TABLE_EVENTS + "("
                + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT,"
                + KEY_TITLE + " TEXT,"
                + KEY_FROM_DATE + " DATE,"
                + KEY_TO_DATE + " DATE,"
                + KEY_DAY_OF_WEEK + " TEXT,"
                + KEY_LOCATION + " TEXT,"
                + KEY_NOTIFICATION_TIME + " DATE,"
                + KEY_TIME_TABLE_ID + " TEXT" + ")";

        db.execSQL(CREATE_EVENTS_TABLE);

        String CREATE_TIME_TABLE = "CREATE TABLE " + TABLE_TIME_TABLE + "("
                + KEY_TIME_TABLE_ID + " INTEGER PRIMARY KEY AUTOINCREMENT,"
                + KEY_TABLE_TITLE + " TEXT,"
                + KEY_STATUS + " TEXT,"
                + KEY_TABLE_COLOR + " TEXT" + ")";

        db.execSQL(CREATE_TIME_TABLE);
    }

    // Upgrading database
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // Drop older table if existed
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_EVENTS);
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_TIME_TABLE);
        context.deleteDatabase(Constants.DATABASE_NAME + ".db");

        createTable(db);


        // Create tables again
        //onCreate(db);
    }

}

Thank you..
