The syntax that DBD::CSV supports is documented in SQL::Statement::Syntax. It clearly states that the supported argument for set functions is a column name, not a numeric expression:
set function ::=
COUNT ( [DISTINCT|ALL] * )
| COUNT | MIN | MAX | AVG | SUM ( [DISTINCT|ALL] col_name )
So the short answer is, no, sorry, you can't currently do that like that in DBD::CSV. Depending on what you want to do, you may be able to build your own UDF (User-Defined-Function) to use here. See SQL::Statement::Function for details of building UDFs.

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).
