selectall_arrayref Columns example?

[Hardy Merrill]

I've read the DBI perldocs and can't find an example of how to
use selectall_arrayref with the Columns attribute - I want to
retrieve all the rows in a select into an array of hashref's,
and I want ALL columns - do I need to specify the Columns
attribute and list *every* column?

An example would be great.

TIA.
