in reply to Programming the Perl DBI
I found it to be great educational material, but has
not proven to be
a reference source for the most part. I don't recommend it
to anyone doing casual database access in Perl. If you are
doing fulltime DBI based development this book presents
much more value and may become more of a reference source.
My use of DBI is primarily of limited complexity and haven't
had need for some of the more advanced topics covered.
It is however well organized with good examples.
