Сбой приложения Android при запуске активности: SQLite

Question

ошибка приложения сбоя:

java.lang.RuntimeException: невозможно запустить действие. ComponentInfo {com.example.notforgot / com.example.notforgot.MainActivity}: android.database.sqlite.SQLiteException: нет такого столбца: Описание (Sqlite code 1 SQLITE_ERROR): при компиляции: SELECT ID, заголовок, описание ОТ примечаний ГДЕ (заголовок как?) ORDER BY Title, (ошибка ОС - 2: такого файла или каталога нет)

некоторый код:
