You are very close. The problem is that you first have to execute the query, which in itself does not return any results. After you execute the query, you then fetch the results, one row at a time. I'm not aware of a way to get all the results at once, sorry. Perhaps another monk can enlighten? For more information, see perldoc DBI and also references, or try this:

$dsn = "DBI:mysql:yip;db.yip.com";
$dbh = DBI->connect($dsn,'me','pass');
$sth = $dbh->prepare("SELECT company FROM company_public;");
$sth->execute();

while($ref = $sth->fetchrow_arrayref) {
    push @companies, $ref->[0];
}

$dbh->disconnect;

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
• Want more info? How to link or How to display code and escape characters are good places to start.
