Why is this create table/ insert query not working in SQLite/Android?

Question

Create table or the Insert query is not working!

public class dbHandler extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 1;
private static final String DATABASE_NAME = "AppointmentsDB";
private static final String TABLE_APPOINTMENTS = "tblAppointments";
private static final String COLUMN_DATE = "dateofapp";
private static final String COLUMN_NAME = "appointment";
private static final String COLUMN_LOCATION = "location";
private static final String COLUMN_Priority = "priority";
private static final String COLUMN_STATUS = "status";

public dbHandler(Context context, String name, SQLiteDatabase.CursorFactory factory, int version) {
    super(context, DATABASE_NAME, factory, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
    String sql = "CREATE TABLE " + TABLE_APPOINTMENTS + "(" + COLUMN_DATE + " TEXT, "
            + COLUMN_NAME + " TEXT,"
            + COLUMN_LOCATION + " TEXT," +
            COLUMN_Priority + " TEXT," +
            COLUMN_STATUS + " TEXT);";

    db.execSQL(sql);
}

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

//add new row
public void addAppointment(Appointments appointment) {
    ContentValues values = new ContentValues();
    values.put(COLUMN_DATE, appointment.getDate());
    values.put(COLUMN_NAME, appointment.getName());
    values.put(COLUMN_LOCATION, appointment.getLocation());
    values.put(COLUMN_Priority, appointment.getPriority());
    values.put(COLUMN_STATUS, appointment.getStatus());
    SQLiteDatabase db = getWritableDatabase();
    db.insert(TABLE_APPOINTMENTS, null, values);
    db.close();
}

//delete
public void deleteAppointment(String appName) {
    SQLiteDatabase db = getWritableDatabase();
    db.execSQL("DELETE FROM" + TABLE_APPOINTMENTS + "WHERE" + COLUMN_NAME + "=\"" + appName + "=\";");
}

//display
public String databaseToString() {

    String dbString = "";
    SQLiteDatabase db = getWritableDatabase();
    String sql = "SELECT * FROM " +TABLE_APPOINTMENTS+ "WHERE 1";

    Cursor c = db.rawQuery(sql,null);
    c.moveToFirst();
    while(!c.isAfterLast()){
        if(c.getString(c.getColumnIndex("appointment"))!= null){
            dbString += c.getString(c.getColumnIndex("appointment"));
            dbString += "\n";
        }
    }

    db.close();

    return dbString;
}

public Cursor getAllData (){
    SQLiteDatabase db = getWritableDatabase();
    Cursor res = db.rawQuery("SELECT * FROM " + TABLE_APPOINTMENTS,null);
    return res;
}

}

Error says there is no column for date. But when i test it with some other string it gives some other column is missing so i'm guessing the table is not getting created
