You can use:
<?php
$rsPenultimateLogin = new WA_MySQLi_RS("rsPenultimateLogin",$yourdbconnection,1);
$rsPenultimateLogin->setQuery("SELECT id_log, datein_log FROM logger_log WHERE idusr_log= ? ORDER BY id_log DESC");
$rsPenultimateLogin->bindParam("i", "".$_SESSION['wa_user_id'] ."", "-1"); //colname
$rsPenultimateLogin->PageNum = 1;
$rsPenultimateLogin->execute();
?>
The PageNum setting will push the recordset to the second record.
