MySQL - 对项目的时间条目进行分组和汇总

标签： php mysql

我从toggl.com获得了这些时间记录数据，我需要将报告的格式与它们提供的内容略有不同 - 这就是为什么我认为我会尝试将csv数据导入MySQL并对其进行格式化我自己通过MySQL和PHP等但我几乎在开始之前就陷入了困境 - 将数据导入MySQL，所以现在我需要在html表中输出它...不知何故。

我有这些数据：

+-----------+---------------------------------------+------------+----------+
|  Project  |                 Task name             |    Date    | Duration |
+-----------+---------------------------------------+------------+----------+
| Project 1 | Task name 2                           | 2016-05-12 | 00:22:03 |
| Project 2 | Task name 1                           | 2016-05-12 | 00:04:24 |
| Project 2 | Task name 1                           | 2016-05-12 | 00:06:27 |
| Project 1 | 3. correction                         | 2016-05-13 | 00:08:00 |
| Project 1 | Small correction                      | 2016-05-13 | 00:02:02 |
| Project 1 | Last correction                       | 2016-05-16 | 00:05:36 |
| Project 1 | Created low-res                       | 2016-05-16 | 00:04:21 |
| Project 2 | Layout                                | 2016-05-24 | 00:27:45 |
| Project 2 | Layout                                | 2016-05-25 | 01:00:00 |
| Project 2 | Finishing                             | 2016-05-25 | 00:15:48 |
+-----------+---------------------------------------+------------+----------+

我梦想实现的是每个项目的数据如下：

Project 2  
-----------------------------------------------------
Date            Tasks                     Total
-----------------------------------------------------
12/05/16        Task name 1               00:10:51
24/05/16        Layout                    00:27:45
25/05/16        Layout, Finishing         01:15:48
-----------------------------------------------------
Project 2 total                           01:54:24

因此，对于每个项目，每个日期都应该有自己的行，包括日期，任务名称 （逗号分隔）和日期

的持续时间的总和

然后是项目总数。

任何帮助都将非常感谢!! ： - ）

修改 

SELECT 
     Project,
     `Task name`,
     Date,
     Duration,
     SEC_TO_TIME( SUM( TIME_TO_SEC( `Duration` ) ) ) AS TotalDuration 
     FROM timerecordings
     GROUP BY Project, Date, `Task name` WITH ROLLUP

给我（不要看日期和时间格式化，这样做很棒）：

+-----------+------------------+------------+----------+----------+
| Project 1 | Task name 2      | 12/05/2016 | 00.22.03 | 00.22.03 |

必须是

之类的东西 
select date, taskName, sum(duration) from tasksTable where Project = "Project 2" group by date

但是如何添加时间，以及如何在一个字段中获取所有taskNames仍然需要进行实验。

您可以使用GROUP_CONCAT聚合函数将所有任务名称组合在一个字符串中。使用SEPARATOR关键字定义分隔符（默认值：'，'）。如果您不希望多次列出相同的任务，请使用DISTINCT。

对于一个项目：

SELECT Date,
  GROUP_CONCAT(DISTINCT `Task name` SEPARATOR ', ') AS Task,
  SEC_TO_TIME(SUM(TIME_TO_SEC(Duration))) AS Total
FROM timerecordings r
WHERE Project = 'Project 2'
GROUP BY Date WITH ROLLUP;

对于所有项目：

SELECT SELECT Project, Date, 
  GROUP_CONCAT(DISTINCT `Task name` SEPARATOR ', ') AS Task,
  SEC_TO_TIME(SUM(TIME_TO_SEC(Duration))) AS Total
FROM timerecordings r
GROUP BY Project, Date WITH ROLLUP;

只是为了让你得到我的最终结果：

 <?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "timerecordings";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT 
            IFNULL (Project,'All Projects') Project,
            IFNULL (Date,'Project total') Date,
            GROUP_CONCAT(DISTINCT `Task name` SEPARATOR ', ') AS Task,
            SEC_TO_TIME(SUM(TIME_TO_SEC(Duration))) AS Total
            FROM timerecordingstable r
            GROUP BY Project, Date WITH ROLLUP;           
        ";
$result = $conn->query($sql);

$data = array();

while($row = $result->fetch_assoc()) {
    $projectname = $row["Project"];
    if (!array_key_exists($projectname, $data)) {
        $data[$projectname] = array();
    }
    $data[$projectname][] = $row;
}

foreach ($data as $projectname => $rows) {
    if($projectname != 'All Projects'){
        echo '<h1>', $projectname, '</h1>';

        echo '<table class="time-table"><tr class="table-header"><th>Date</th><th>Tasks</th><th>Time used</th><tr>';

        foreach ($rows as $row) {
            //Convert Total into seconds
            $str_time = $row["Total"];
            $str_time = preg_replace("/^([\d]{1,2})\:([\d]{2})$/", "00:$1:$2", $str_time);
            sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
            $time_seconds = $hours * 3600 + $minutes * 60 + $seconds;

            // Round to nearest minute
            $time_seconds = round($time_seconds/60)* 60;

            $hours = floor($time_seconds / 3600); //Hours
            $minutes = floor(($time_seconds / 60) % 60); //Minutes

            //Convert minutes to two decimal number (like 15 minutes = 0.25 hour etc.)
            $minutes = $minutes / 60;
            $minutes = round($minutes,2);
            $minutes = $minutes*100;

            $seconds = $time_seconds % 60; //Seconds - I don't use it but kept to show it's possible

            //Loop each row
            if($row["Date"] == 'Project total'){
                echo '<tr class="table-footer"><td>', $row["Date"] , '</td><td>' , '&nbsp;' , '</td><td>' , $hours, ',',$minutes, ' hour(s)</td></tr>';
            } else {
                $prettyDate = DateTime::createFromFormat('Y-m-j', $row["Date"]);
                echo '<tr><td>', $prettyDate->format('d-m-Y') , ':</td><td>' , $row["Task"] , '</td><td>' , $hours, ',',$minutes, ' hour(s)</td></tr>';    
            }
        }

        echo '</table>';
    }
}

$conn->close();

?>

结果：
