Question

我有一个用于生成文档（Excel）的 ReportBuilder 类。我想要的是选择员工和日期，然后计算该日期的总工作时间。这是我的php文件

<?php
class EmployeeSummaryTimesheet extends ReportBuilder{

    public function getMainQuery(){
        $query = "SELECT
(SELECT `employee_id` from Employees where id = at.employee) as 'Employee',
(SELECT concat(`first_name`,' ',`middle_name`,' ', `last_name`) from Employees where id = at.employee) as 'Employee',

TIMEDIFF(out_time, in_time) as 'Working Hours'
FROM Attendance at";

        return $query;
}

public function getWhereQuery($request){
        if(($request['employee'] != "NULL" && !empty($request['employee']))){
            $query = "where employee = ? and in_time >= ? and out_time <= ? group by employee;";
            $params = array(
                $request['employee'],
                $request['date_start']." 00:00:00",
                $request['date_end']." 23:59:59",
            );
        }else{
            $query = "where in_time >= ? and out_time <= ? group by employee;";
            $params = array(
                $request['date_start']." 00:00:00",
                $request['date_end']." 23:59:59",
            );
        }
 return array($query, $params);
    }}

现在我无法得到第一天 TIMEDIFF（out_time，in_time）值的特定日期期间的总和，而不是工作时间总和帮助我

编辑 - 这里我有两个表Employee and Attendance（id，employee（这是Employee表中的员工ID），in_time，out_time）

编辑：我取消DATE_FORMAT（in_time，＆＃39;％Y-％m-％d＆＃39;）为＆＃39;日期＆＃39;，我不需要此列

Answer 1

您希望每位员工和日期有一条记录，并显示该员工当天的总工作时间。因此，按员工和日期加入和分组，并将工作时间相加。

select
  e.employee_id,
  concat(e.first_name, ' ', e.middle_name, ' ', e.last_name) as employee_name 
  date_format(at.in_time, '%Y-%m-%d') as 'Date',
  sum(timediff(at.out_time, at.in_time)) as 'Working Hours'
from attendance at
join employee e on e.id = at.employee
where ...
group by e.employee_id, date_format(at.in_time, '%Y-%m-%d');

Answer 2

这就是我自己做的答案

    public function getMainQuery(){

        $query = "SELECT
(SELECT `employee_id` from Employees where id = at.employee) as 'Employee',
(SELECT concat(`first_name`,' ',`middle_name`,' ', `last_name`) from Employees where id = at.employee) as 'Employee',
DATE_FORMAT(in_time, '%Y-%m') as 'MONTH',
CONCAT(
FLOOR(
SUM(CASE WHEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))<=0 THEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))=''
ELSE TIME_TO_SEC(TIMEDIFF(out_time,in_time)) END)/3600) ,':',
FLOOR(MOD(
SUM(CASE WHEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))<=0 THEN TIME_TO_SEC(TIMEDIFF(out_time,in_time))=''
ELSE TIME_TO_SEC(TIMEDIFF(out_time,in_time)) END),3600)/60)) as 'WORKING HOURS'
FROM Attendance at";

        return $query;

    }

    public function getWhereQuery($request){
        if(($request['employee'] != "NULL" && !empty($request['employee']))){
            $query = "where employee = ? and in_time >= ? and out_time <= ? order by in_time;";
            $params = array(
                $request['employee'],
                $request['date_start']." 00:00:00",
                $request['date_end']." 23:59:59",
            );
        }else{
            $query = "where in_time >= ? and out_time <= ? group by employee;";
            $params = array(
                $request['date_start']." 00:00:00",
                $request['date_end']." 23:59:59",
            );
        }

        return array($query, $params);
    }
}

如何使用sql查询获取时间总和值？
