You described a correct way to use trigger-populated primary keys.
As for the refresh/update, we are constrained by Update from database wizard by Microsoft.
But we are working on a tool which will give our customers possibility to simplify the work with entity models.

The before insert trigger method may interfere with our existing legacy application. The Oracle database we currently uses sequences to generate the primary keys for most tables. We have a situation currently where we need to insert data in multiple parent-child tables. What is your recommended solution if before-trigger is not an option for us?

Thanks.

Please post here or send me (support * devart * com, with subject "Sequences, Identity columns, and inserting data") the script you are using for inserting the auto-generated values into the primary key columns.

What are you referring to when you mention modify the StoreGeneratedPattern attribute on the property element? I see it exists for my SQL Server Data Model. Can I just add that to my Oracle Data Model and everything should work?

Yes, you can.
If you are using Entity Data Model Wizard then you should edit the model with XML Editor after its generation.
Devart Entity Developer 2.0 Beta 2 will allow the storage model editing.
