Parse.com get value with query

Question

I\'ve been looking for an example on how to use Parse.com queries. It\'s been really vague. I think it should start with:

ParseQuery query=ParseQuery.getQuer         


        

Answer 1

To find the list of user whose username starts with abc,You can use the condition

query.whereStartsWith("username", "abc");

So the entire query looks as

ParseQuery<ParseObject> query = ParseQuery.getQuery("YourClassName");
query.whereStartsWith("username", "abc");
query.findInBackground(new FindCallback<ParseObject>() {
  public void done(List<ParseObject> object, ParseException e) {
    if (object == null) {
      Log.d("score", "The getFirst request failed.");
    } else {
      Log.d("score", "Retrieved the object.");
    }
  }
});

Answer 2

I would not recommend using getFirstInBackground for getting a query, it is much better to use findInBackGround and then filtering the value you are looking for.

Answer 3

Parse's Android Guide has a basic query example here which will return the first object which matches your constraints:

ParseQuery<ParseObject> query = ParseQuery.getQuery("YourClassName");
query.whereEqualTo("ID", "someID");
query.getFirstInBackground(new GetCallback<ParseObject>() {
  public void done(ParseObject object, ParseException e) {
    if (object == null) {
      Log.d("score", "The getFirst request failed.");
    } else {
      Log.d("score", "Retrieved the object.");
    }
  }
});
