sql - Count of dates over a period of time -


i have table1 employee data below

| empid | department | startdate | enddate | | 1 | d1 | 2014-02-05 | 2014-06-18 | | 1 | d3 | 2013-08-29 | 2014-02-05 | | 2 | d3 | 2014-05-07 | 2014-06-18 | | 2 | d4 | 2013-08-29 | 2014-05-06 | | 2 | d3 | 2014-06-19 | 2014-12-01 |

i have table table2 absence data

empid department absentcedate 1 d3 2013-09-24 1 d3 2013-09-30 1 d3 2013-10-25 1 d1 2014-02-06
1 d1 2014-02-08 2 d3 2013-08-30 2 d3 2013-09-30 2 d3 2013-10-30 2 d3 2014-11-11 2 d4 2014-05-10

i joined both tables find count of absence dates employee based on empid using teh following code:

select   t1.empid empid,                     t1.department department,                     count(absencedate) numdaysabsent ,                     startdate, enddate,                 table1 t1                     join table2 t2 se on sa.empid = se.empid            group t1.empid ,                     t1.department                     startdate, enddate 

my results below

empid department numdaysabsent startdat enddate 1 d1 5 2014-02-05 2014-06-18 1 d3 5 2013-08-29 2014-02-05 2 d3 5 2014-05-07 2014-06-18 2 d3 5 2014-06-19 2014-12-01 2 d4 5 2013-08-29 2014-05-06

instead want group numberofabsences department , diaply them as

empid department numdaysabsent startdate enddate 1 d1 2 2014-02-05 2014-06-18 1 d3 3 2013-08-29 2014-02-05 2 d3 3 2014-05-07 2014-06-18 2 d3 1 2014-06-19 2014-12-01 2 d4 1 2013-08-29 2014-05-06

how proceed? i've been trying figure out how achieve that. how group them startdate , enddate , excatly dipaly number of absences period in department? inputs? trying in sql server

i think need more conditions on join, including department , date. best guess this:

select   t1.empid empid, t1.department department,          count(absencedate) numdaysabsent ,          startdate, enddate,     table1 t1 join          table2 t2          on t1.empid = t2.empid , t1.department = t2.department ,             t2.absencedate between t1.startdate , t1.enddate group t1.empid, t1.department, startdate, enddate;
