You can override fetchall_arrayref method.
Just create dbilimit.pl
use strict;
package DBI;
my $fetchall_arrayref;
our $ROWS_LIMIT;
INIT {
$ROWS_LIMIT = 10;
$fetchall_arrayref = \&fetchall_arrayref;
}
no warnings;
sub fetchall_arrayref {
my ($sth, $slice, $max_rows) = @_;
$max_rows = $ROWS_LIMIT
unless defined $max_rows;
$fetchall_arrayref->($sth, $slice, $max_rows);
}
1;
and require it after use DBI; line
P.S. the code is not tested so it may have some bugs

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).

or How to display code and escape characters
are good places to start.
