PHP MySQL - 更改表格以在街道地址匹配的同一行显示记录

Question

早上好，我需要一些帮助，我将不胜感激。我有一张如下所示的表格：

但我希望它看起来像这样，以便用户更容易阅读：

我如何将其更改为那样？这是当前代码：

<?php

$sql = "SELECT
companyname,
ordernumber,
equipment,
theserial,
type,
theaddress
FROM table";

$result = mysqli_query($con, $sql);

?>


<table id="moreinfotable" name="moreinfotable" class="table table-bordered" style="width:100%">
<thead>
<tr>
<th>Name</th>
<th>OrderNumber</th>
<th>Equipment</th>
<th>Serial</th>
<th>Type</th>
<th>Address</th>

</tr>
</thead>

<?php

while($row = mysqli_fetch_array($result)) { 

$companyname = $row['companyname'];
$ordernumber = $row['ordernumber'];
$equipment = $row['equipment'];
$theserial = $row['theserial'];
$type = $row['type'];
$theaddress = $row['theaddress'];

echo '<tr>';
echo '<td>' . $companyname . '</td>';
echo '<td>' . $ordernumber . '</td>';
echo '<td>' . $equipment . '</td>';
echo '<td>' . $theserial . '</td>';
echo '<td>' . $type . '</td>';
echo '<td>' . $theaddress . '</td>';
echo'</tr>';

} 

?>

Answer 1

对于固定的类型列表（此处为新的送货和取货），您可以使用条件聚合直接在 SQL 中转换数据集：

select companyname, ordernumber, address,
    max(case when type = 'New Delivery' then equipment end) as delivery_equipment,
    max(case when type = 'New Delivery' then serial    end) as delivery_serial,
    max(case when type = 'Pickup'       then equipment end) as pickup_equipment,
    max(case when type = 'Pickup'       then serial    end) as pickup_serial,
from mytable
group by companyname, ordernumber, address

Answer 2

我不确定，但您是否尝试订购您的查询？ 例如：

SELECT * FROM exam ORDER BY exam_date;

这意味着从考试中选择所有内容并按考试日期排序。

"SELECT
companyname,
ordernumber,
equipment,
theserial,
type,
theaddress
FROM table 
ORDER BY theaddress"
