您好，我知道目前我的数据库中有一些重复的列，因为我遇到了一些错误，我只是想让我的网站正常运行。我目前正在努力展示一个上市的最高出价。我很惊讶我如何找到每个特定列表的最高出价，因为出价似乎都捆绑在一个表中。我想知道是否有人可以帮我做此？
<?php
require 'config.php';
if(isset($_POST['submit']))
{
$valueToSearch = $_POST['valueToSearch'];
// search in all table columns
// using concat mysql function
$query = "SELECT * FROM listings` WHERE CONCAT(`location`, `description`, `price`, `date`,`title`) LIKE '%".$valueToSearch."%'";
$query2 = "SELECT `listID` FROM listings"
$search_result = filterTable($query);
}
else {
$query = "SELECT * FROM `listings`";
$search_result = filterTable($query);
}
// function to connect and execute the query
function filterTable($query)
{
$conn = mysqli_connect("localhost", "root", "", "auction");
$filter_Result = mysqli_query($conn, $query);
return $filter_Result;
}
?>
