使用mysql php的客户终身价值

输入代码这里花了一个星期试图解决这个问题,通过组合来自不同来源的东西,但尚未正常工作,它有点工作。

我基本上有一个订单表,我试图按照他们的第一个订单日期对客户进行分组,并显示该组到目前为止的总支出

这是我的SQL查询:

SELECT DISTINCT email, billing_name,
FORMAT(SUM(total),2) AS total,
DATE_FORMAT(MIN(orderdate), '%Y-%m') AS firstorder,
DATE_FORMAT(MAX(orderdate), '%Y-%m') AS lastorder
FROM orders
GROUP BY email
ORDER BY firstorder ASC

和我正在做的PHP:

$rows = array();
while($row = mysql_fetch_array($query))
$rows[] = $row;
foreach($rows as $row) {
    $currMonth = $row['firstorder'];
    $total += $row['total'];
    if ($currMonth != $prevMonth) {
            echo $currMonth.' = $'.$total';
            $prevMonth = $currMonth;
            $total = 0;
        }
    }

这给了我一个列表:

    2010-05 = $230.49
    2010-06 = $557.32
    2010-08 = $223.38

但是这些数字并没有加起来,我做错了什么?如何显示一个团队在其他月份花了多少钱?这就是我最终想要显示数据的方式http://www.quickcohort.com/

请帮忙!谢谢!

取决于您真正追求的是什么以及您的数据是什么样的。

如果数据如下:

email          |BILLING NAME|Total  |OrderDate
----------------------------------------------
john@gmail.com |John Smith  |200.00 |15/05/2010
john@gmail.com |John Smith  | 15.49 |19/10/2010
john@gmail.com |Rico Swavez | 15.00 |10/08/2010
jane@gmail.com |Jane Doe    |250.00 |23/06/2010
jane@gmail.com |Jane Doe    |307.32 |27/10/2010
juan@gmail.com |Juan Valdez |223.38 |30/08/2010

则...

SELECT email, billing_name,
FORMAT(SUM(total),2) AS total,
DATE_FORMAT(MIN(orderdate), '%Y-%m') AS firstorder,
DATE_FORMAT(MAX(orderdate), '%Y-%m') AS lastorder
FROM orders
GROUP BY email, billing_name
ORDER BY firstorder ASC

将返回

EMAIL          | BILLING NAME |TOTAL |FIRSTORDER | LASTORDER 
------------------------------------------------------------
john@gmail.com | John Smith   |215.49|2010-05    | 2010-10
jane@gmail.com | Jane Doe     |557.32|2010-06    | 2010-10
john@gmail.com | Rico Swavez  | 15.00|2010-08    | 2010-08
Juan@gmail.com | Juan Valdez  |223.38|2010-08    | 2010-08

首先在mysql中运行查询你得到了你想要的结果吗?如果没有,那么问题出在SQL中,而不是PHP中。如果SQL返回你想要的,那么问题出在PHP

以下查询应该可以解决问题:

SELECT 
    FORMAT(SUM(z.`totalSpent`),2) AS cohortRevenueToDate, 
    z.`firstOrderMonth`,
    GROUP_CONCAT(`email`) 
FROM 
(
    SELECT 
        `email`,
        SUM(`total`) AS totalSpent, 
        DATE_FORMAT(MIN(`orderdate`), '%Y-%m') AS firstOrderMonth 
    FROM `orders`
    GROUP BY `email`
) AS z
GROUP BY z.`firstOrderMonth`
ORDER BY z.`firstOrderMonth` ASC

如果您对每个队列组成都感兴趣,我会加入GROUP_CONCAT。
