How to make Query Reference?

Hi,

I am just wondering: how to make Query Reference like the example in the attachment? what's the purpose of this manipulation?

Thank you in advance.

Hi

I would suggest that is a rather unusual thing to do.  But if you want to do it you need to drag query 1 to the right handside of query 2 in the queries diagram window.

The reason for doing it is so that you can use the items in query 1 in query 2.
