    if (res.moveToFirst()) {
        do {
            int value = res.getColumnIndex("name");
            if(value != -1 && res.getString(value).equals(fieldName))
            {
                isExist = true;
            }
            // Add book to books

        } while (res.moveToNext());
    }

    return isExist;
