Answer 1

试试这个：

<table border="1">
    <tr>
        <th>Degree</th>
        <th>Diploma</th>
        <th>Post Diploma</th>
    </tr>

    <?php
    
    $stmt = $conn->prepare("SELECT 
        MAX(CASE WHEN level = 'Degree' THEN percentage END) AS Degree,
        MAX(CASE WHEN level = 'Diploma' THEN percentage END) AS Diploma,
        MAX(CASE WHEN level = 'Post Diploma' THEN percentage END) AS Post_Diploma
        FROM tbl_academic_qualification WHERE member_no = :emp_id");

    
    $stmt->execute();
    while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
        echo "<tr>";
        echo "<td>" . $row['Degree'] . "</td>";
        echo "<td>" . $row['Diploma'] . "</td>";
        echo "<td>" . $row['Post_Diploma'] . "</td>";
        echo "</tr>";
    }
    ?>
