Answer 1

What's the algorithm of working hours? Supposing working hours equals checkout time minus checkin time, I've got this SQL:

SELECT 
  Emp_id,
  report_date,
  MIN(report_time) AS checkin_time,
  MAX(report_time) AS checkout_time,
  DATE_FORMAT (MAX(report_time) - MIN(report_time), '%h') AS working_hours
FROM
  report 
GROUP BY Emp_id;

But, it sucks when employees go to work again and again....

I'm wandering why the employees should checkout in next day. It's also confusing when I saw employee 06 who checked out after two days. 囧

For night shift, I tried this SQL which might be helpful:

SELECT 
  a.`id` AS employ_id,
  ADDTIME(MIN(a.adjustedDateTime), '12:00:00') AS check_in_time,
  ADDTIME(MAX(a.adjustedDateTime), '12:00:00') AS check_out_time,
  TIMEDIFF(
    MAX(a.adjustedDateTime),
    MIN(a.adjustedDateTime)
  ) AS working_time,
  COUNT(0) AS report_times,
  DATE_FORMAT(a.adjustedDateTime, '%Y-%m-%d') AS report_date
FROM
  (SELECT 
    `Emp_id` AS id,
    SUBTIME(
      CONCAT(report_date, ' ', report_time),
      '12:00:00'
    ) AS adjustedDateTime 
  FROM
    report) a 
GROUP BY a.`id`,
  DATE_FORMAT(a.adjustedDateTime, '%Y-%m-%d') 
ORDER BY a.`id`, report_date;

I used SUBTIME to make the report_time which in one shift be gathered into one day. Then group by the date. Thus got the result.

<?php
require_once('dbconn.php');
$q="select employee_oid, min(concat(report_date,' ',report_time)) as checkin, max(concat(report_date,' ',report_time)) as checkout from report_master where 1 group by employee_oid,report_date;";
$rec = mysql_query($q);
$k=0;
$i=0;
$previous_empid=0;
if(mysql_num_rows($rec) > 0)
{ 
$arr=$arr2 = array();

while($row = mysql_fetch_array($rec))

{
$employee_oid = $row['employee_oid'];
$minmumdate = $row['checkin'];
$maxdate = $row['checkout'];
$timestamp1 = strtotime($minmumdate);
$timestamp2 = strtotime($maxdate);
$hour = abs($timestamp2 - $timestamp1)/(60*60);

$arr[$employee_oid][] = array(
'hours'=>$hour
);

}
        //print_r($arr);
foreach($arr as $key=>$result){
//echo $key.'   key value';
$total_hours=0;
foreach($result as $key1=>$result1){
$total_hours= $total_hours + $result1['hours'];
}
if($total_hours>176) {
    $extra_hours = $total_hours - 176;
    $extra_wages = $extra_hours * 31.25;
                }
$arr2[$key][] = array(
    'total_hours'=>$total_hours,
    'extra_hours'=>$extra_hours,
    'extra_wages' =>$extra_wages
    );

}

print("<pre>");
print_r($arr2);
exit();
foreach($arr2 as  $key=>$result){
echo $key.' = > total_hours '.$result['total_hours'].' extra_hours '.$result['extra_hours'].' extra_wages '.$result['extra_wages'].'</br></br>';
            }
    }

?>

I have this query:-

select DATE_FORMAT(yb_date, '%d') AS yb_date,'2' as roll,'asd' AS staff_name,CASE WHEN yb.yb_date> '5050-12-31' THEN '' WHEN yb.yb_date<'0' THEN '' WHEN yb.yb_date> CURDATE() THEN '' WHEN yb.day_status = 'Holiday' AND date(a.attend_date) IS NULL THEN 'H' WHEN date(a.attend_date) IS NULL THEN 'A' ELSE 'P' END AS status,CASE WHEN time(min(attend_date)) IS NULL THEN '00:00:00' ELSE time(min(attend_date)) END as in_time,CASE WHEN time(max(attend_date)) IS NULL THEN '00:00:00' ELSE time(max(attend_date)) END as out_time,CASE WHEN timediff(time(max(attend_date)),time(min(attend_date))) IS NULL THEN '00:00:00' ELSE timediff(time(max(attend_date)),time(min(attend_date))) END as duration from yearbook yb LEFT join attendance_essl a ON date(a.attend_date)=yb.yb_date AND a.emp_id='000012' where yb.yb_date between '2019-09-29' AND '2019-10-05' group by yb.yb_date,a.emp_id order by yb.yb_date ASC

Output is :-

yb_date

in_time
out_time
