  I am not sure if this is what you mean but this is what I do to see 
what DB calls are being made. I add a print statement just before the 
actual SQL call (which I actually print to the filehandle 'LOG' which 
points to a log file). For example:

$db_update=$DB->prepare("UPDATE file_info SET file_size=?, file_perm=?, 
file_acc_time=?, file_mod_time=?, file_user_uid=?, file_user_name=?, 
file_group_uid=?, file_group_name=? WHERE file_parent_dir=? AND 
file_name=? AND file_type=?") || die...

...

if ( $log_level >= 4 ) { print LOG " |- ".__LINE__." DBI: UPDATE 
file_info_".$dev_id." SET file_size=$size, file_perm=$mode, 
file_acc_time=$atime, file_mod_time=$mtime, file_user_uid=$uid, 
file_user_name=$user, file_group_uid=$gid, file_group_name=$group WHERE 
file_parent_dir='/' AND file_name='.' AND file_type='d';\n"; }
		$db_update->execute($size, $mode, $atime, $mtime, $uid, $user, $gid, 
$group, "/", ".", "d") || die...

  Noting of course that the quoting might be slightly off because a 
prepared statement automatically quotes values as needed. If you wanted 
to be really carefully you could quote the values for your log like so:

if ( $log_level >= 4 )
{
	$db_user=$DB->quote($user);
	$db_group=$DB->quote($group);
	print LOG " |- ".__LINE__." DBI: UPDATE file_info SET file_size=$size, 
file_perm=$mode, file_acc_time=$atime, file_mod_time=$mtime, 
file_user_uid=$uid, file_user_name=$db_user, file_group_uid=$gid, 
file_group_name=$db_group WHERE file_parent_dir='/' AND file_name='.' 
AND file_type='d';\n";
}

  I hope this was along the lines of your question.
