kyle is right that selectcol_arrayref() is a method of the database handle ($dbh), not of the statement handle ($sth). Here's one way to remember which DBI object the various methods belong to : database handle methods take data out of the database in a single step whereas statement handle methods require multiple steps - prepare, execute, fetch.
Another way to tell is by the error message: Can't locate object method "selectcol_arrayref" via package "DBI::st". That message says it can't find that method in that package, in other words, that object has no such method. Either you misspelled method name, or you are using it on the wrong object.

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).
