Why do you want an array without a reference? Arrays that are accessed by references can do exactly the same things, only the syntax is a bit different.
By the way, consider DBIx::Simple, which allows you to do:
my @emps = $db->query("SELECT ename FROM emp ORDER BY ename")->flat;
foreach my $emp (@emps) {
...
}
"flat" means: take all results and return them as one flat list.

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).
