Funny no-one mentioned it so far: You should consider to develop the habit to always use prepared statements, passing in such things as parameters:
[...]
my $queryStatementHandler = $dbh->prepare("SELECT field1,field2 FROM m
+y_table WHERE LEFT(field3, ?) = ?");
$query->bind_param(1, $value_1);
$query->bind_param(2, $var);
$query->execute();
[...]
Not only is this (and the shorter forms DBI allows for) usually considered good style, but usually the safest form to talk to a DB.

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.
