ORDER BY problem

Hey Ray

Have got this recordset

<?php
$WADAvehicle_inspections = new WA_MySQLi_RS("WADAvehicle_inspections",$DBConnection,20);
$WADAvehicle_inspections->setQuery("SELECT * FROM vehicle_inspections ORDER BY VehiclesDate DESC");
$WADAvehicle_inspections->execute();
?>
<?php } else { ?>
<?php
$WADAvehicle_inspections = new WA_MySQLi_RS("WADAvehicle_inspections",$DBConnection,1);
$WADAvehicle_inspections->setQuery("SELECT * FROM vehicle_inspections WHERE VehiclesInspector = ? ORDER BY VehiclesDate DESC");
$WADAvehicle_inspections->bindParam("s", "".($_SESSION['UserLastName']) ."", "-1"); //colname
$WADAvehicle_inspections->execute();
?>
<?php } ?>



and this in a repeat block

<div class="coffee-span-2 resultsWrapper leftColumn"> <?php if(WA_Auth_RulePasses("Administrator")){ ?><a class="link-text resultsLinks dates timesheet" href="vehicleinspections_update.php?VehiclesID=<?php echo($WADAvehicle_inspections->getColumnVal('VehiclesID')); ?>
<?php echo(isset($_GET["pageNum_WADAvehicle_inspections"])?"&pageNum_WADAvehicle_inspections=".intval($_GET["pageNum_WADAvehicle_inspections"]):""); ?>"><?php echo(($WADAvehicle_inspections->getColumnVal('VehiclesDate'))?date('d M y',strtotime($WADAvehicle_inspections->getColumnVal('VehiclesDate'))):''); ?></a>
<?php } else { ?>
<?php echo(($WADAvehicle_inspections->getColumnVal('VehiclesDate'))?date('d M y',strtotime($WADAvehicle_inspections->getColumnVal('VehiclesDate'))):''); ?>
<?php } ?> </div>



it should be filtering/ordering by the date but as you can see by this screenshot its not http://prntscr.com/13g113t

Many thnaks

What is the column data type for the VehiclesDate column in the database?

dang

varchar - is there anyway to change it to date without it setting all dates to 0?

You can probably create a second column "tempDate" and then run a query like:

UPDATE vehicle_inspections SET tempDate =VehiclesDate

If it doesn't copy that way, then as long as you have a standard date format you might be able to get it to work with str_to_date() like:

UPDATE vehicle_inspections SET tempDate = str_to_date(VehiclesDate, '%Y-%m-%d')

see: https://www.w3schools.com/mysql/func_mysql_str_to_date.asp

Then once you are sure the dates got copied to the new column properly, delete the old column and rename the new one.
