php - 修改我的 SELECT 语句以考虑某个单词

Question

如何让我的 SELECT 语句检查某个标题是否以单词开头并将其显示在列表底部？请看下面我的例子。

<?php
    @$DBn = new mysqli('localhost','REMOVED','REMOVED','REMOVED');

    if (mysqli_connect_errno()) {
        echo 'Cannot connect to database: ' . mysqli_connect_error();
    }

    else {
        $Queryn = "SELECT Title FROM Courses where Status = 'Live' order by Title";
        $Resultn = $DBn->query($Queryn);
        $NumResults = $Resultn->num_rows;

        while ($Rown = $Resultn->fetch_assoc()) {
            echo "<li><a href='http://www.domain.com/course-detail.php?Title=". $Rown['Title'] ."'>". $Rown['Title']  ."</a></li> \n";
        }
    }
?>

以上代码将从类(class)中选择每个标题并按字母顺序显示。如果类(class)以“Refresher”一词开始，我该如何做到这一点，它会将其放在最后一门类(class)之后的底部？

类(class)A， 类(class)B， 类(class) C， 类(class) D, 进修类(class)A， 进修类(class) B， 复习类(class) C， 进修类(class)D

表结构如下。

Answer 1

SELECT Title
FROM Courses
WHERE Status = 'Live'
ORDER BY
    (CASE WHEN Title LIKE 'Refresher%' THEN NULL ELSE Title END) IS NULL ASC,
    Title DESC
