我在MySQL中分組日期時遇到問題。無效的參數號不允許在PDO MySql問題使用分組時
下面是從數據庫中調用我的整個代碼:
// Make todays date
$todays_date = date('Y-m-d', strtotime('now')) . '00:00:00';
// Get all from database and group them by day
$query = $pdo->prepare("SELECT bookingdate FROM madebookings WHERE bookingdate >= :$todays_date GROUP BY DATE_FORMAT(bookingdate,'%b, %d %Y')");
$query->execute(array(':todays_date' => $todays_date));
$query_number = $query->rowCount();
// Lets build the table
$files_table = '';
if ($query_number > 0) {
while ($fetch = $query->fetch()) {
//get the items needed
$bookingdate = $sanitise->justDate(date('Y-m-d', $fetch['bookingdate']));
$dateUrl = $date('Y-m-d', $fetch['bookingdate']);
$files_table .="<tr>";
$files_table .= "<td>".$bookingdate."</td>";
$files_table .= "<td><a href='view-day-bookings.php?date=".$dateUrl."' class=\"btn btn-info btn-sm btn-icon icon-left\"><i class=\"entypo-pencil\"></i>Click here to view bookings</a></td>";
$files_table .= "</tr>";
}
}
我得到的錯誤是:
Warning: PDOStatement::execute(): SQLSTATE[HY093]: Invalid parameter number: parameter was not defined in /XXX/XXX/Documents/www/Applications/Controllers/Bookings/group.php on line 8
Warning: PDOStatement::execute(): SQLSTATE[HY093]: Invalid parameter number in /XXX/XXX/Documents/www/Applications/Controllers/Bookings/group.php on line 8
正如你所看到的問題是在執行行,我懷疑它認爲它需要將%b,%d%Y放入預先準備好的聲明中,但我可能會在此錯誤:(
無論如何,任何人都可以告訴我我做錯了什麼嗎?
