BDM aggregated objects JPQL

Hi,

I have a table A and other B. Table B has an aggregated field referring table A.
I am trying to list all elements from table A not referenced in table B.
The goal is to show this list in a process Form.

How can I do it:

• Through JPQL
• Through Javascript

Thanks a lot !

I wonder with the arrival of BDM, if I chose as RDBMS (postgresql) for example. es that I could run stored procedures directly in the database. Because I do not know if the BDM have the same basic architecture as a normal relational data. foreign key etc.

Hi there,

I'm wondering if (how) it is possible to use specific data objects in the bdm and use JPQL custom requests with joins in order to retrieve composite / agregated data of other business objects through the standard Bonita bdm API?

This in order to retrieve main data from a core object with, for instance, joins and counts of aggregated sub-objects built within the DB layers to be directly displayed on forms.
