-------------------------------------------------
1 2013-05-01 01:01:00 1 26 //date 01 from home-----
2 2013-05-01 08:11:00 1 27 //date 01 from office--- Present
3 2013-05-02 03:41:00 1 28 //date 02 from home---
4 2013-05-02 09:12:00 1 29 //date 02 from office-
5 2013-05-02 22:32:00 1 30 //date 02 from home---Present
6 2013-05-03 01:43:00 1 31 //date 03 from home
7 2013-06-03 23:25:00 1 32 //date 03 from home----------Homework
8 2013-06-03 02:15:00 2 33 //other employee
an employe will be considered as present if there 1 or many records where time between 8am and 8pm
an employe will be considered as workedFromHome if there 1 or many records where time NOT between 8am and 8pm, and not present on that day
note: do not count a day as workedFromHome if there is any record time between 8am and 8pm (means workedFromHome is only counted if he is not resent on that day)
I want to display monthly report of a employee eg. c_emp=1 for month eg. 5
like this in 1 query
c_emp presentCount HW_Count
1 3 1
or separatly query 1
c_emp presentCount
1 3
and query 2
c_emp HW_Count
1 1
I have tried for counting present working fine
select count(distinct(date_format(c_sdate,'%e'))) as count
from ita_check
where date_format(c_sdate,'%m')=5
and c_emp=1
and date_format(c_sdate,'%H%i')>=800
and date_format(c_sdate,'%H%i')<=2000
and for counting fromHome giving wrong count
select count(distinct(date_format(c_sdate,'%e'))) as count
from ita_check
where date_format(c_sdate,'%m')=5
and c_eid=1
and c_id not in (
select c_id
from ita_check
where date_format(c_sdate,'%m')=5
and c_eid=1
and (date_format(c_sdate,'%H%i')<=800 or date_format(c_sdate,'%H%i')>=2000)
)
and date_format(c_sdate,'%H%i')<800
or date_format(c_sdate,'%H%i')>2000
in above query for counting Working
the sub query returns 1 and 2
while the outer eliminate c_id=2 but not c_id=1

Answer 1

Try this query
SELECT c_emp,
sum(if(cnt>=1,1,0)) as Office,
count(*)-sum(if(cnt>=1,1,0)) as WFH from (
select c_emp, Date(c_sdate),
sum(if(c_sdate BETWEEN Date(c_sdate) + interval 8 hour
AND Date(c_sdate) + interval 20 hour, 1, 0)) as cnt
from table1
group by c_emp, Date(c_sdate)) tmp
group by c_emp
SQL FIDDLE:
| C_EMP | OFFICE | WFH |
------------------------
| 1 | 2 | 2 |
| 2 | 0 | 1 |
For monthly report
SELECT c_emp, date_format(c_date, '%c %Y') as Mnth,
sum(if(cnt>=1,1,0)) as Office,
count(*)-sum(if(cnt>=1,1,0)) as WFH from (
select c_emp, Date(c_sdate) as c_date,
sum(if(c_sdate BETWEEN Date(c_sdate) + interval 8 hour
AND Date(c_sdate) + interval 20 hour, 1, 0)) as cnt
from table1
group by c_emp, Date(c_sdate)) tmp
group by c_emp,Mnth
SQL FIDDLE:
| C_EMP | MNTH | OFFICE | WFH |
---------------------------------
| 1 | 5 2013 | 2 | 1 |
| 1 | 6 2013 | 0 | 1 |
| 2 | 6 2013 | 0 | 1 |
