How to upgrade database schema built with EclipseLink? [message #390291] Thu, 16 July 2009 09:37 Go to previous message

Hi,

I'm looking for a general solution for upgrading database schema built
with EclipseLink. How do you do it in your projects?

The first solution that comes to my mind is to create my own mechanism
for upgrading databases, with SQL scripts doing all the work. But in
this case I'll have to remember about creating new scripts every time
the object mappings are updated. And I'll still have to deal with
low-level SQL queries, instead of just defining mappings and allowing
the ORM tools to do all the job...

So the question is how to do it properly. Maybe some tools allow for
simplifying this task (for example, I heard that Rails have such
mechanism built-in).

Thanks for any suggestions.

Markus
