I'd urge even more care when using Stored Procedures - unless you limit how much data is brought back into memory you could easily gobble up a LOT of system memory and if you then do transformation on that data, the Heap Space will disappear quickly leading to a system outage. Unfortunately I've seen it happen in Production when Stored Procedure data volumes are not thought about and ALL records are brought into memory.

I you don't want to create view between the tables we can achieve this using Execute Stored Procedure plugin where we can execute the SQL statements and it will return the result in dictionary.We can use this approach if the data volume is high.

Please go through below link. You will get basic understanding on how to create a view.
www.w3resource.com/.../creating-view.php

After creating the view , Create a Data type(CDT) for that view and map it to Data store. Create a Query entity based on your requirement.This would resolve your issue

Thanks,

If you're looking to join on other tables then I'd recommend creating a SQL View that does the data manipulation and then having your queryEntity read the view. Care will be needed on the View access depending on expected data volumes and growth of data on the tables being joined together.
