Nik,

First, I am not sure what DB module you are using, I am going to assume DBI though. And without the name of the DBD driver you are using it is impossible to actually answer your question.

In general, getting column info is not that simple, at the very least, you first need to specify the table whose columns you want to examine. To get you started, here is a link to the DBI Database Handle Methods section in the DBI docs, scroll down (for a while) until you see the column_info method, it will tell you were to start at least.

Bookmark this too (it always comes in handy): The DBI site
