When updating data on a database from a form, general practice is to take the data from form and pass it to a update SQL statement.
use CGI;
use DBI;
sub update_mytable($$$$$) {
my ($db,$id,$name,$rank,$serialno)=@_;
# Use late binding, good practice for some DBs; doesn't hurt others
my $sql = "update mytable set name = ?, rank = ?, serialno =? where
+id= ?";
my $sth;
# Wrap db activities in eval so non-fatal
eval($sth = $db->prepare($sql) );
eval( $sth->execute($name,$rank,$serialno,$id); ) unless $@;
#
return $@?$@:1;
}
my $q = new CGI;
my $d = new DBI(....);
my $id = $q->param('id');
...
my $serialno = $q->param('serialno');
update_mystable($d,$id,$name,$rank,$serialno);
Is that what you meant to ask? Try looking at Merlyn's page or Ovid's page for hints on CGI tips.

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).
