My data model has are more than two levels. How can I include in where clause 2 and third level child objects.
In your documentation about querying related objects, you have an example of related objects: phonebook, contact, and address. The example query is based on the contact object class. How would you write the same query using the phonebook class? Find all Phonebooks where “address.city = ‘Smallville’”
StringBuilder whereClause = new StringBuilder();whereClause.append( “PhoneBook[contacts]” );whereClause.append( “.objectId=’” ).append( savedPhoneBook.getObjectId() ).append( “’” );whereClause.append( " and " );whereClause.append( “address.city = ‘Smallville’” ); BackendlessDataQuery dataQuery = new BackendlessDataQuery();dataQuery.setWhereClause( whereClause.toString() );List<Contact> result;result = Backendless.Persistence.of( Contact.class ).find( dataQuery ).getCurrentPage();
