Hi,

this is my sample of simple sql code.



create table work_time
(
 date datetime
,working_time_second int
,person varchar(10)
)

insert into work_time
select '2004-06-24 06:19:40.000',3525,'John1' union all
select '2004-06-24 08:03:30.000',13525,'John1' union all
select '2004-06-24 08:03:30.000',1234,'Jim1' union all
select '2004-06-24 10:03:30.000',19284,'Jim1' union all
select '2004-06-24 08:10:30.000',17425,'Lester'

What i want to achieve is, to get the results as following:

hour | work_time_minutes_within_hour | person
------------------------------------------------
6 | 40 | John1
7 | 18 | John1
8 | 57 | John1
9 | 60 | John1
10 | 60 | John1
11 | 48 | John1
8 | 21 | Jim1
10 | 57 | Jim1
11 | 60 | Jim1
12 | 60 | Jim1
13 | 60 | Jim1
.
.
.

where "work_time_minutes_within_hour" is a working time that a person worked from the date until date + working_time_second. If time overlaps the full hour, the calculation goes into next hour as shown in example.

thank you for your ideas.

[code]SELECT v.number AS hour,
CASE WHEN v.number = DATEPART(hh,t.StartDate)
THEN 60-DATEPART(mi,t.StartDate)
WHEN v.number = DATEPART(hh,t.EndDate)
THEN DATEPART(mi,t.EndDate)
ELSE 60
END AS work_time_minutes_within_hour,
t.person
FROM (SELECT date AS StartDate,DATEADD(ss,working_time_second,date) AS EndDate,Person FROM Table )t
CROSS JOIN master..spt_values v
WHERE v.type='p'
AND v.number BETWEEN DATEPART(hh,t.StartDate) AND DATEPART(hh,t.EndDate)
[/code]
