Rajani Karuturi commented on CLOUDSTACK-6835:
---------------------------------------------
if reusing GenericDaoBase is possible, that would be better. I havent put a lot
of thought into it.

> about 198 of the issues reported by covery scan[1] on 26 May, 2014 are in the
> Upgrade###to###.java code
> and many of them related to Resource leaks and not closing the prepared
> statements.
> I think we should have a DB abstraction layer in the upgrade path so the the
> developer who needs to do select/insert/update data in the upgrade path need
> not write native sqls and worry about these recurring issues.
