What is gojng on today?
A general blindness?
What this poor fellow was asking is what to do in case of
an empty record set.
using $sth->rows is dead wrong.
rows is used in non-select statements.
Somebody suggested using $sth->fetchrow_arrayref
in void context, without catching the result anywhere. Wow!
The simple way is
$sth->execute();
my $recordset = $sth->fetchall_arrayref();
if (@$recordset) {
# there are records. Do something here
}
else {
# empty recordset. Do something else.
}
Or, if you don't want to get all records at once
my $found = 0;
while (my $rec = $sth->fetchrow_arrayref()) {
#do something
$found = 1;
}
unless ($found) {
# recordset was empty.
# do something else
}

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).
