【问题描述】：
我在我的电子商务应用程序中有一个称为商店积分（预付款）的功能，如果客户在他的帐户中有积分，客户可以在其中兑换商店积分。
到目前为止一切正常。
我想要在客户的“我的帐户详细信息”中显示这样的数据：
SC_OC S_OC SC_Amount SC_Alloted SC_Used SC_Balance
ORD-0001 -- 1000 1100 0 1100
-- ORD-0001 -- -- 300 800
SC_OC = Store_Credit_Order_Code
S_OC = Store_Order_Code
每当客户购买商店积分时，如果SC_Alloted 不是0，那么商店积分将通过添加它来更新它。所以它会是这样的：
SC_OC S_OC SC_Amount SC_Alloted SC_Curent SC_Used SC_Balance
ORD-0001 -- 1000 1100 1100 0 1100
-- ORD-0001 -- -- 1100 300 800
ORD-0002 -- 2500 2800 3600 0 3600
S_OC 和 SC_Used 数据来自orders 表，其余详细信息来自store_credits_orders 表。
我得到的是：
SC_OC S_OC SC_Amount SC_Alloted SC_Curent SC_Used SC_Balance
ORD-0001 ORD-0001 1000 1100 1100 0 1100
ORD-0001 ORD-0001 1000 1100 1100 300 800
ORD-0002 ORD-0001 2500 2800 3600 0 3600
这是我尝试过的 PHP 代码：
<?php
$table = '';
$queryToGetStoreCredit = "SELECT * FROM
store_credits_orders sco,
orders ord
WHERE
sco.SCO_CustEmailAdd = '".$_SESSION["Customer"]["email"]."'
AND
ord.CustEmailAdd = '".$_SESSION["Customer"]["email"]."'
AND
ord.CustEmailAdd = sco.SCO_CustEmailAdd";
$validate->Query($queryToGetStoreCredit);
if ($validate->NumRows() >= 1) {
while ($rows_sco = $validate->FetchAllDatas()) {
$i = 0;
$table .= '<tr>';
$table .= '<td>'.$rows_sco["SCO_OrderCode"].'</td>';
$table .= '<td>'.$rows_sco["OrderCode"].'</td>';
$table .= '<td>'.$rows_sco["SCO_OrderDate"].'</td>';
$table .= '<td>'.$rows_sco["SCO_Purchase_Amount"].'</td>';
$table .= '<td>'.$rows_sco["SCO_Credit_Alloted"].'</td>';
$table .= '<td>'.$rows_sco["AppliedCredits"].'</td>';
$table .= '<td>'.$rows_sco["SCO_Credit_Alloted"].'</td>';
$table .= '</tr>';
}
}
?>
我如何做到这一点？
非常感谢任何帮助。
更新 1：
在 RST 的回答之后，我得到以下输出：
SC_OC S_OC SC_Amount SC_Alloted SC_Curent SC_Used SC_Balance
ORD-0001 -- 1000 1100 1100 0 1100
ORD-0001 -- 1000 1100 1100 300 800
ORD-0002 -- 2500 2800 3600 0 3600
更新 2：
我以某种方式试图获得所需的输出。但是我不能得到超过 1 个结果，也就是说，如果 store_credits_orders 中有超过 1 个订单，我只会得到第一个结果，而不是其他结果。代码如下：
<?php
$queryToGetStoreCredit = "SELECT * FROM store_credits_orders WHERE SCO_CustEmailAdd = '".$_SESSION["Customer"]["email"]."'";
$validate->Query($queryToGetStoreCredit);
if ($validate->NumRows() >= 1) {
while ($rows_sco = $validate->FetchAllDatas()) {
$used = $i = 0;
$table .= '<tr>';
$table .= '<td>'.$rows_sco["SCO_OrderCode"].'</td>';
$table .= '<td>--</td>';
$table .= '<td>'.$rows_sco["SCO_OrderDate"].'</td>';
$table .= '<td>'.$rows_sco["SCO_Purchase_Amount"].'</td>';
$table .= '<td>'.$rows_sco["SCO_Credit_Alloted"].'</td>';
$table .= '<td>'.$used.'</td>';
$table .= '<td>'.( $rows_sco["SCO_Credit_Alloted"] - $used ).'</td>';
$table .= '</tr>';
$queryToGetOrder = "SELECT * FROM orders WHERE CustEmailAdd = '".$rows_sco["SCO_CustEmailAdd"]."'";
$validate->Query($queryToGetOrder);
while ($row = $validate->FetchAllDatas()) {
$table .= '<tr>';
$table .= '<td>--</td>';
$table .= '<td>'.$row["OrderCode"].'</td>';
$table .= '<td>--</td>';
$table .= '<td>--</td>';
$table .= '<td>--</td>';
$table .= '<td>'.$row["AppliedCredits"].'</td>';
$table .= '<td>'.($rows_sco["SCO_Credit_Alloted"] - $row["AppliedCredits"]).'</td>';
$table .= '</tr>';
}
}
}
?>

在 RST 的评论之后，在 $rows_sco 上使用 print_r()，我得到以下数组结果：
