Hi,
I would recommend always to avoid hard coding SQL into Java code. It is
very hard to maintain and read.
If there is something, which prevents using JPA/Hibernate, e.g. the
database relational model doesn't reflect the object-oriented domain
very well or we have to live with many stored procedures concurrently, I
would choose a framework, which enables to externalize the SQL code
(into XML).
I worked on a larger project(s) with a lot of PL/SQL code, we moved to
myBatis (previously iBatis) very soon for Java backend:

Hello,
I would like to start a discussion about the subject. I think this is
something we need to do if one day we want to be able to use any
database other than PostgreSQL.
I did an small example of what it takes and how it looks like to have
the SQL code into the DAOs:

It isn't rocket science, it isn't an exciting task, it isn't fun, but
something I think we should eventually do.
I appreciate any comment about how and when to do this, including
those saying that instead of this primitive approach we should use
this or that ORM framework.
