Hello Alexander,<br>
<br>
Thank you for your reply. I was hoping to avoid SQL queries, but
I'll setup a way to handle these cases simply, waiting for the
migration feature in September.<br>
<br>
Thanks again,<br>
<br>

<div>Currently you need to execute ALTER TABLE command manually.
It is not that hard if the modification is just adding new
column. We plan to add migration tool in September, this tool
will be able to do everything automatically.</div>
<br>
Here you can see an example how simple migrations can be done
manually: <a moz-do-not-send="true"

everyone,<br>
<br>
I'm eager to begin working with Pony ORM. That sounds so
simple compared to other ORMs I've seen. However, I have a
concern regarding entity's evolution.<br>
<br>
I didn't see an automatic way to handle these type of
modifications. For instance, what happens if we work with
an entity, then decide to add a new field to it? Or to
change the type of a given field? Or to remove one?
Performing specific updatess (called migrations in other
ORMs) can be sometimes useful, too. For instance, if we
want to delete two fields but combining their old results in
a single one. Is there any way to do that using Pony ORM?<br>
<br>
Thank you very much for your answer!<br>
<br>
Happy hacking,<br>
<br>
Vincent<br>
