perldoc DBI:
"finish"
$rc = $sth->finish;
Indicate that no more data will be fetched from this statement han
+dle
before it is either executed again or destroyed. You almost certai
+nly do
*not* need to call this method.
Adding calls to "finish" after loop that fetches all rows is a com
+mon
mistake, don't do it, it can mask genuine problems like uncaught f
+etch
errors.

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).
