This has just caught me out in a while loop for getting information from a database
my $query = $dbh->prepare("SELECT idFrame, name, colour FROM F
+rame");
$query->execute();
while (my ($frame) = $query->fetchrow_hashref) {
push @frames, $frame;
}
This loop never ends!
Although $query->fetchrow_hashref returns undef once all the rows have been returned, the condition as whole doesn't so the loop continues...
This is what I really wanted (and how have)
my $query = $dbh->prepare("SELECT idFrame, name, colour FROM F
+rame");
$query->execute();
while (my $frame = $query->fetchrow_hashref) {
push @frames, $frame;
}

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).
