Capability of selecting variables to use in a stored process while running it

[Hoverman]

I was just wondering whether it is possible to select the variables a user intends to use for a stored process while executing it not when designing it. For example, if i have country, gender, job title, city are the variables in my stored process, i should be able to select/check country, gender at one time to run my stored process and then country, city, gender at another time. You help will be appreciated as i'm still new to stored processes.

Yes it is possible. There are multiple approaches to it.
To begin with have a look at the following paper.
