You forgot to add the column in your create table statement :

 db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" +
        KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
        KEY_NAME + " TEXT NOT NULL, " +
        KEY_DAY + " TEXT NOT NULL, " +
        KEY_HOTNESS + " TEXT NOT NULL);"
        );
