Hello

The sizing of the request is very important from a system performance perspective. You can use a very simple method like queryid() or queryidnodate() to get the count. When working with query() or queryrecord() the sizing prevents any timeouts of the full request.

I want to import data for entity like person,company.

So I think queryid() or queryidnodate() are not useful for this , as result of this method return only default fields(createddate,updateddate,createdby,updatedby).
