the database cannot store the date in that format.
it must store the date in the yyyy-mm-dd format.
you change the format that is used to display the date on the individual pages using the date function though.
so instead of using:
<php echo $row_recordsetName['dateColumn']; ?>
to write the date to the page, use:
<php echo(date("d/m/Y", strtotime($row_recordsetName['dateColumn']))); ?>
