I want to select data from my table that was uploaded in the last 7 days. Here is what i have so far but it is not working.
$sql9="SELECT SUM(TruckDamage)
WHERE DATEDIFF(`upload_date`, CURRENT_DATE) < 7
AS TotalTruckDamageSum FROM jwtdriversbank2";
$result9=mysql_query($sql9);
$rows9=mysql_fetch_assoc($result9);
$sum8=$rows9['TotalTruckDamageSum'];
?>
<div>
Total Truck Repair Cost's: £<?echo $sum8?><br>
Can anybody help please?
should be
sql9="SELECT SUM(TruckDamage)
AS TotalTruckDamageSum FROM jwtdriversbank2 WHERE DATEDIFF(`upload_date`, CURRENT_DATE()) < 7";
The problem is that your query is invalid. You are assigning TotalTruckDamageSum to WHERE
. Second syntax error is that FROM
should be before WHERE
. And last but not least is that bigger date should be first if you want to get non-negative result of DATEDIFF
.
Should be:
$sql9="SELECT SUM(TruckDamage) AS TotalTruckDamageSum FROM `jwtdriversbank2` WHERE DATEDIFF(CURRENT_DATE,`upload_date`) <= 7";
$sql9="SELECT SUM(TruckDamage) AS TotalTruckDamageSum
where upload_date >= DATE_SUB(now(), INTERVAL 7 DAY)
FROM jwtdriversbank2";
$result9=mysql_query($sql9);
$rows9=mysql_fetch_assoc($result9);
$sum8=$rows9['TotalTruckDamageSum'];
?>
<div>
Total Truck Repair Cost's: £<?echo $sum8?><br>
