I would take trammell's suggestion a step further and also not recreate the statement handle every time and actually take advantage of the statement handle (and placeholders)-- i think this will have a decent improvement in the performance (amount of gain is probably db-dependent):
my $dbh = DBI->connect('DBI:mysql:diet', {RaiseError => 1, AutoCommit
+=> 0} ) || die "Failed to connect: $DBI::errstr";
my $sth = $dbh->prepare( qq{select topic FROM table1 WHERE uri LIKE ?}
+ );
search($sth, 'foo');
search($sth, 'bar');
$sth->finish();
$dbh->disconnect(); #disconnect from database;
sub search{
my $sth = shift; # require statement handle (this could probably be
+ a global var instead if desired)
my $q = shift; # take search parameter from html <form/>
my $found = 0; #initialize category found count;
$sth->execute($q);
my $rows = $sth->fetchall_arrayref( {} );
printf "%d rows found for '%s'.\n", scalar(@$rows), $q;
foreach my $row (@$rows){
printf " Topic: %s\n", &topic($row->{topic});
}
}

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.
