How to create a report that shows items with zero dependencies?

How to create a report that shows items with zero dependencies?

I am trying to create a report that has two tables (forms as they're called in Zoho), one table is Stores, the other is Accounts. The Accounts form has a field has a foreign key from the Stores table. How do I create a report that shows me how many Stores do not have a foreign key associated with data in the Accounts table?

The MS-SQL equivalent of the results I would like to see in the report would be:

       SELECT s.Store_Name 
      FROM Stores s
      WHERE s.Store_Name NOT IN (
            SELECT DISTINCT a.Store_Name
            FROM Accounts a)

I'm a bit confused on how to do this with the Zoho Creator.
