Hey monks,
I am in a situation where I need to the count of rows returned by a 'SELECT' query. However, I have read that the DBI::rows function is unreliable at best. After having tried to think of other ways to get a row count on a query, the best I could come up with was:
$sth = $dbh->prepare("SELECT name FROM people WHERE l_name LIKE 'B%'")
+;
$sth->execute();
while ( $name = $sth->fetchrow_array() ) {
$count++;
}
I was wondering if there is a less verbose, and perhaps more efficient way of getting a row count. Processing the results of the query is completely unnecessary to this script, so it seems kind of silly to have to loop through all of them.
Thanks in advance.
Amel - f.k.a. - kel

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).
