How to execute raw SQL

How can I execute raw sql? I want to use DISTINCT and COUNT. Also, how do I retrieve all records of my query without worrying about pagesize?

Direct DB access is not possible with Backendless Cloud.

For counts you can use the aggregate function and for distinct you add distinct=true in the request URL.


I don’t understand what you mean by request URL. Am talking about using the Android sdk

This is my code

String make = “Toyota”;
String whereClause = “make = '” + make + “’”;
DataQueryBuilder queryBuilder = DataQueryBuilder.create();
Backendless.Data.of(Automotive.class).find(queryBuilder, new AsyncCallback<List>() {

        public void handleResponse(List<Automotive> response) {

            String model = response.get(0).getModel();
	// I want to get all distinct models.How do i use the Distinct keyword?
	//And how do i get a count of distinct models?


        public void handleFault(BackendlessFault fault) {


I was talking about REST since you never mentioned anything about Android till now.

Here’s how to set distinct with Android:

queryBuilder.setDistinct( true );

Please provide sample code using aggregate function.

See the docs at COUNT - Backendless SDK for Android/Java API Documentation

Am assuming Count aggregates integers in a column. For example I have a column called Views, and I have 3 records with views 5 ,10 and 15. Am expecting the Count function to return 30.

After using DataQueryBuilder.create().setProperties(“Count(Views)”)

How do I get the actual count?

How do I get the count in the returned response object?

Count does what it says :wink: it counts the number of objects. You can specify objectId as the column to count objects by.

Sorry, it’s the SUM aggregate function I want to use.

DataQueryBuilder dataQueryBuilder = DataQueryBuilder.create();
dataQueryBuilder.setProperties( “Sum(totalBoxOffice) as grandTotal” );
Backendless.Data.of( “Movie” ).find( dataQueryBuilder, new AsyncCallback<List>()
public void handleResponse( List response )
// print out the first object from the collection
Log.i( “MYAPP”, response.get( 0 ) );

public void handleFault( BackendlessFault fault )
Log.e( “MYAPP”, fault.toString() );

How do I extract “grandTotal” from the response object?

((HashMap)response.get( 0 )).get( “grandTotal” )
