Dynamic SOQL in Map with unknow sobject?

is it possible to do SOQL for the unknown object without for loop as below

string theQuery = 'Select '+fiels+' From'+obj_frm +whr; Map <Id, object> oppMap = new Map<Id, object>((List<object>)Database.query(theQuery));

Answer 1

You need to use SObject as the value, not Object.

Map<Id, SObject> opportunities = new Map<Id, SObject>(Database.query(...));
