An alternative suggestion might be to create a db view that contains the result of a stored procedure, then map the view like a regular entity being sure to declare the properties as read-only in the mapping file. I've seen this implemented when using Oracle for aggregate reporting because stored proc support wasn't there for Oracle. An example would be, get top 100 selling products in previous 24 hours. A view might not be applicable if you need to execute a procedure with params, and it makes several assumptions about the underlying db, but then so does exec dbo.SomeProcedure. For returning compositions of read-only instances, projections, aliases and AliasToBean may be of interest. That’s cool.

What if your proc returns a graph, could you map on to it? Lets say we want to shape 3 entities out of this proc... Product, Category & Inventory.. Product.Id Product.Name Product.Category.ID Product.Category.Name Product.Inventory.OnHand Product.Inventory.InStock Thats slick Davy. What if your proc returns a graph, could you map on to it?

Lets say we want to shape 3 entities out of this proc… Product, Category & Inventory..

Product.Id
Product.Name

Product.Category.ID
Product.Category.Name

Product.Inventory.OnHand
Product.Inventory.InStock
