Hi,

I doing a Proof Of Concept to figure out how efficient to call a store
procedure using EclipseLink. I was able to call oracle store procedure
using EclispeLink with Scalar/primitive data types (link Integer,
varchar etc). I wanted to understand how can I handle Oracle Store
procedure from EclipseLink with collection(Oracle Types/User defined
types) as input or output parameters. I would really appreciate if
some one help me understand this with an example.

Thanks
MAK

Good luck with this. I have also been seriously considering the use of Oracle specific features such as VARRAYs and NESTED TABLES, but I think the focus of the EclipseLink project (now that it is open source, and possibly less well resourced by Oracle?) is more around the database features that are common to all databases.

I was told that the Workbench is not being actively developed, and that the focus was on Dali. If Dali is supposed to work with all JPA providers then there will be little room for Oracle specific features.

Perhaps it is best if we do stick to common SQL constructs and therefore have the greatest choice of tools? This is kind of annoying, as being able to model 1:n (where n is small) collections would be very useful.

I've made available a simple example on gist:

Hope this helps,

Thanks for the example.

Would it be possible to show the equivalent code using JPA annotations?

I am interested to understand how much of the boilerplate code can be removed by the use of the annotations.

Cheers
Andrew
