Separating SQL from code

Separating SQL from code

Hi, I'm somewhat new to patterns and J2EE but I was wondering if someone
could help with a question I have.

I'm wondering if there are any patterns of practices that document ways to
extract SQL from code or that discuss if this is a good thing or not?

I have read the J2EE Patterns book and done a bit of research (especially on
DAO) but can find anything that talks about a total separation of SQL from
code. I am wondering is removing SQL from code (and possibly placing it in a
properties file or such) might be a good way of putting all the SQL in one
place to make changes (maintenance) easier.

The best I could find was this article which documents one approach but not
the pros or cons:

Thanks!
