Why don't you have access at the database level?
my $dbh = DBI->connect("dbi:Oracle:host=server.domain.com; sid=sid; po
+rt=1521", "username", "password")
This contains all the relevant details to connect via sqlplus or
SQL Developer. I don't mean any disrespect, but extracting such a large amount of rows and processing them by hand (or any other tool) can only be several orders of magnitude slower than doing it in SQL or at least PL/SQL. Could you explain the requirement, even in abstract form, here or on Oracle's forum? I'm sure people would come up with suggestions for an improved query.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
