Subject torque table schema- how to alter existing table
Date Mon, 20 Sep 2004 23:24:59 GMT
Hi List:
I like to know if anybody who uses Torque platform in his product has
done
anything on object model migration from old release to new release. This
seems to be a missing piece in Torque project. Am I missing something? 
Example Scenario:
I have an existing application that uses Torque as OR platform contains
a
set of business objects. 
In this new release, we are altering the definition of business object
by adding new fields for some objects and deleting some fields for
others. I would like to know how other users are handling the two
situations: (a) When you add a new field to an existing object and (b)
when you delete a field in an existing object. So that the old data can
be kept and properly defaulted. 
Do Torque supports the "table alter"? 

I have searched the Wiki ,docs and mail archive but could not find any
recommendation/reference from the Torque developers/gurus or reference
to
some design patterns. 

Regds 
 Ajitesh
