Joins in Hana Modeling

All,

I have a situation where I want to join two tables say Customer and Genders.

a) Customer Left Join with Genders ( Get all Customers if no Gender exist in Genders table)

b) Customer INNER JOIN with Genders ( Get Customers whose Gender matching in Genders table)

What is the best way to model this scenario.

I can do this using CESCRIPT but I hoping if there is any to do the same using Graphical calc view.

Any expert views?

Thanks,
