BC4J - Stored Procedures

Question

The previous topics on the above topic and the sample applications go a long way to show how to use stored procedures as a source for a view object or entity object. However, the reference material does not show how to use a stored procedure that returns multiple rows as the source for an entity object.
Questions:
- Can a stored function that returns a reference cursor be used as the source for an entity object?
- How are multiple instances of the entity object handled in the doSelect method? Is there an approach like the "createRowFromResultSet" method used in a VO or does one simply need to iterate through the result set?
- Is there an example of handling multiple rows for an entity object, either with or without the use of a reference curor?
Thanks for any assistance on this matter.

Answer 1

There are two stored procedure samples. Your "Dive into BC4j" tip and related topics provide a variation of the "Creating a View Object Based on a Static Set of Values" sample. I understand this approach.
The second sample, StoreProc, uses an approach described in the help topics: "About Using Stored Procedures" and "Calling Stored Procedures". The approach entails overriding the doSelect and doDML methods of an entended EntityImpl object. The sample and help topics only return one row.
My questions focus on how to handle a callable statement that returns multiple rows and how to populate the attribues of multiple instances of an EntityImpl.
Please consider by original questions in the context described herein.
Thanks
