Lets see. I've used the following DB's with perl:

• Oracle - because this is what was already there
• Sybase - same reason
• Solid - same reason
• MS Sql Server - same reason
• MySQL - because I wanted a free/fast DB
• Postgres - because its free and has better Unicode support than MySQL.
• Keyed files on a Tandem (like dbm files) using middleware that presented it as an ODBC data source - To get access to the data on this "legacy" platform from scripts running on a Unix box.

IMHO, oracle takes too much work to admin. If you have a good DBA around to install/configure/feed it I guess my experiences with it would be better. Sybase is ok. Solid is cool because it takes almost 0 work to admin once it is set up. MySQL is one of my favorites, but I miss some features that it lacks like subqueries and views. Postgres is my current "favorite" because it gives me everything that MySQL does with more "cool features", but I've only been messing with it for 2 months so far. The tandem ODBC middleware product wasn't fun to work with, but it was great because of what it made possible: a web interface to a lecacy DB.

One feature that I want in a DB that only some support (and this is kind of nit-picky): case sensitive table and column names. My OS and programming language are case sensitive, I think my DB should be the same way.

I generally avoid stored procs or database specific features. The main reason for this is to make it easy to move from one DB to another easily. If I do use them I "hide" them behind a perl abstraction layer, so I can move the functionality from the stored proc to perl if I want to move to a DB that doesn't support stored procs (or that just handles them diffrently).
