sqlite selection returns no results

I have this table:

and I try to select phone = 9 and isBlocked = 1

SQLiteDirectCursorDriver: SELECT KEY_ID FROM BLOCKED_PHONES_TABLE WHERE KEY_PHONE = ? AND KEY_IS_BLOCKED = ?

code:

    Cursor cursor = this.getReadableDatabase().query(
            BLOCKED_PHONES_TABLE,
            new String[] { KEY_ID  }, KEY_PHONE+" = ? AND "+KEY_IS_BLOCKED+" = ?",
            new String[] { phone, "1" }, null, null, null);

      while(cursor.moveToNext()) {
        result = new Phone();
        result.id = (cursor.getInt(0));
        result.phone = phone;
        result.isBlocked = true;
    }
    return result;
}

but I get empty results set.

what do i need to fix?
