Question

我已经实现了一个过滤我的表的解决方案，但它也让我失去了我想要的主要功能之一。 GROUP BY ID DESC所以最新发布在顶部。

第一次查看没有任何过滤器的表时，我希望它也是GROUP BY ID DESC，但过滤器的设置方式我不能这样做。有办法解决吗？我的代码在

之下

<?php 
// Check connection
require '../inc/connection.php';
//Select All from Game
$result_else = "SELECT * FROM game WHERE listDate >= NOW() - INTERVAL 1440 MINUTE ";

//Search Function
if (isset($_POST['search'])) {
$search_term = mysqli_real_escape_string($con, $_POST['search_box']);   
$result_else .= "AND Region LIKE'%{$search_term}%'";
$result_else .= "OR gameType LIKE'%{$search_term}%' GROUP BY id DESC LIMIT 25";
}

?>

如果我希望没有任何过滤器的表的原始视图具有GROUP BY ID DESC LIMIT 25将如何完成？

感谢您的帮助

Answer 1

是的，可以做到

$result_else = "SELECT * FROM game WHERE listDate >= NOW() - INTERVAL 1440 MINUTE ";

//Search Function
if (isset($_POST['search'])) {
    $search_term = mysqli_real_escape_string($con, $_POST['search_box']);   
    $result_else .= "AND Region LIKE'%{$search_term}%'";
    $result_else .= "OR gameType LIKE'%{$search_term}%' ";
}
// $result_else .= "GROUP BY id DESC LIMIT 25";
$result_else .= "ORDER BY id DESC LIMIT 25";

但不确定是否要求GROUP BY或ORDER BY

GROUP BY对内容进行分组。

ORDER BY以asc或desc订单

也许它可以帮到你：

<?php
// Check connection
require '../inc/connection.php';
//Select All from Game
$result_else = "SELECT * FROM game WHERE listDate >= NOW() - INTERVAL 1440 MINUTE ";

//Search Function
if (isset($_POST['search'])) {
    $search_term = mysqli_real_escape_string($con, $_POST['search_box']);
    $result_else .= " AND Region LIKE'%{$search_term}%'";
    $result_else .= " OR gameType LIKE'%{$search_term}%' GROUP BY id DESC";
}
$result_else .= " ORDER BY id LIMIT 25";

?>

在我的Mysql语句中包含GROUP BY id
