If you're not using placeholders for your database code, then perhaps you've got a field with an embedded apostrophe in it. For example:
my $t = "Bobby Tables' and HeadName=1; drop table mytable;";
my $SQL = "select * from mytable where id='$t'";
print $SQL, "\n";
If you expand the resulting SQL and reformat it, you'll see that it's rather fortunate that HeadName isn't a column in your table!
select * from mytable
where id='Bobby Tables'
and HeadName=1;
drop table mytable;

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).
