Monthly totals 月份返回NULL，只输出运行总计

Question

我正在使用以下内容尝试以如下格式输出我的每月总计：

 January
 Quoted Total : £678
 Parts Total : £432
 Profit Total : £244

 February
 Quoted Total : £650
 Parts Total : £345
 Profit Total : £123

等等…………

    // Work Complete Totals
    $query = $db->query("SELECT SUM(pricequoted) AS pricequotedtotal,
                                SUM(partprice) AS partpricetotal,
                                SUM(profit) profittotal,
                                DATE_FORMAT('%Y-%m', completeddate) AS month 
                         FROM `jobdetails` 
                         WHERE jobstatus='complete'
                         GROUP BY DATE_FORMAT('%Y-%m', completeddate)");


    echo '<div style="float:right; padding-right:10px;">';
    echo '<strong>Work Complete Totals</strong>';

    while($result = $query->fetch_object()) {

        $pricequoted = number_format($result->pricequotedtotal, 2, '.', '');
        $partprice   = number_format($result->partpricetotal, 2, '.', '');
        $profit      = number_format($result->profittotal, 2, '.', '');

        echo '<p><strong style="color:red;">Quoted Total : &pound;'.$pricequoted.'</strong></p>';
        echo '<p><strong style="color:Darkorange ;">Parts Total : &pound;'.$partprice.'</strong></p>';
        echo '<p><strong style="color:green;">Profit Total : &pound;'.$profit.'</strong></p>';
    }

    echo '</div>';

我遇到的问题是它只输出运行总计，所以我在页面底部一次得到以下内容，但仅此而已：

Work Complete Totals
Quoted Total : £1460.00

Parts Total : £541.43

Profit Total : £918.57

如果我在 phpmyadmin 中运行上述查询，我​​会得到结果：

pricequotedtotal    partpricetotal  profittotal        month
      1460              541.43      918.5699999999998   NULL

我的表格布局如下：

id  customerID  name    facebookuserurl tel email   address itemforrepair   repairdetails   otherdetails    pricequoted partprice   profit  datepartordered jobstatus   dateofcompletion    datecreated itemnumber

下面是一个示例行：

这是我的表结构：

Answer 1

伊恩，

我想下面的查询会对你有所帮助。

SELECT SUM(pricequoted) AS pricequotedtotal, SUM(partprice) AS partpricetotal, SUM(profit) profittotal, MONTHNAME(dateofcompletion) FROM jobdetails WHERE jobstatus='complete' GROUP BY DATE_FORMAT(dateofcompletion, '%Y-%m ') 按完成日期排序；

+-----------------+----------------+------------- +------------------------------+ |报价总额 |部分价格总计 |利润总额 |月名（完成日期）| +-----------------+----------------+------------- +------------------------------+ | 140 | 114.98 | 25.02 |五月 | | 140 | 114.98 | 25.02 |六月 | +-----------------+----------------+------------- +------------------------------+ 2 行（0.00 秒）

Answer 2

你可以试试这个查询

SELECT SUM(pricequoted) AS pricequotedtotal,
       SUM(partprice) AS partpricetotal,
       SUM(profit) AS profittotal,
       MONTHNAME(completeddate) AS month 
           FROM `jobdetails` 
       WHERE jobstatus='complete'
           GROUP BY MONTH(completeddate)

上表中不存在列“completeddate”，请改用“dateofcompletion”

因此，运行查询并将它们放入 while 循环将产生您想要的结果

我也看到了你的表结构，最好使用varchar、int、float 等来格式化一个表。text 列消耗更多内存

Answer 3

你需要改变这个

DATE_FORMAT('%Y-%m', completeddate)

到

DATE_FORMAT(completeddate, '%Y-%m')

这就是为什么您在month 列中得到NULL，因此只有一行。

见manual entry。

Answer 4

SUM(pricequoted) AS pricequotedtotal,
SUM(partprice) AS partpricetotal,
SUM(profit) profittotal,

应该是

SUM(pricequoted) AS pricequotedtotal,
SUM(partprice) AS partpricetotal,
SUM(profit) AS profittotal,

你错过了一个“AS”
