I have this table. It keeps check-in time of the employee, but this employee didn't check-in everyday in the month. So what I want it to be is something like this
stmpdate intime
1 2014-10-01
2 2014-10-02
3 2014-10-03
4 2014-10-04
5 2014-10-05
6 2014-10-06
7 2014-10-07
8 2014-10-08 08:04:43
9 2014-10-09 07:57:13
10 2014-10-10 07:57:14
11 2014-10-11
12 2014-10-12
13 2014-10-13
14 2014-10-14
15 2014-10-15
16 2014-10-16 07:59:56
17 2014-10-17 07:45:56
18 2014-10-18
19 2014-10-19
20 2014-10-20
21 2014-10-21
22 2014-10-22
23 2014-10-23
24 2014-10-24
25 2014-10-25
26 2014-10-26
27 2014-10-27
28 2014-10-28
29 2014-10-29

I tried to make a temp table which contains every date in the month, and then left join it with the first table I mentioned, but it seemed to not work.
declare #datetemp table (
stmpdate varchar(10)
);
insert into #datetemp
SELECT '2014-10-01'
UNION ALL
SELECT '2014-10-02'
UNION ALL
SELECT '2014-10-03'
....
and
SELECT dtt.stmpdate, intime
FROM #datetemp dtt left join v_dayTimesheet
on dtt.stmpdate=v_dayTimesheet.stmpdate
WHERE (emp_no = '001234567')
here is the result of query above
stmpdate intime
2014-10-08 08:04:43
2014-10-09 07:57:13
2014-10-10 07:57:14
2014-10-16 07:59:56
2014-10-17 07:45:56
and here is the result of select * from #datetemp
2014-10-01
2014-10-02
2014-10-03
2014-10-04
2014-10-05

Answer 1

you're filtering for only where emp_no has a value. if they didn't check in, it won't return on that row because you just have date info and no employee number. so you have to allow for equal or null.
SELECT dtt.stmpdate, intime
FROM #datetemp dtt
left outer join v_dayTimesheet
on dtt.stmpdate=v_dayTimesheet.stmpdate
WHERE emp_no = '001234567' or emp_no is null
also, for your dates... check this out: http://www.sqlservercurry.com/2010/03/generate-start-and-end-date-range-using.html
DECLARE
#StartDate datetime = '2010-01-01',
#EndDate datetime = '2010-03-01'
;WITH datetemp as
(
SELECT #StartDate as stmpdate
UNION ALL
SELECT DATEADD(day, 1, stmpdate)
FROM datetemp
WHERE DATEADD(day, 1, stmpdate) <= #EndDate
)
SELECT stmpdate
FROM datetemp;
you would then select from datetemp as a normal table. beware, though, a common table expression can only be used once and immediately following the with statement.
just trust me on this one... run this query and see how your blank lines occur:
SELECT dtt.stmpdate, intime, emp_no
FROM #datetemp dtt
left outer join v_dayTimesheet
on dtt.stmpdate=v_dayTimesheet.stmpdate
WHERE emp_no = '001234567' or emp_no is null
all these lines will return with emp_no = 001234567
stmpdate intime
2014-10-08 08:04:43
2014-10-09 07:57:13
2014-10-10 07:57:14
2014-10-16 07:59:56
2014-10-17 07:45:56
and all your blank lines will have null as emp_no.

Answer 2

I got my answer!!
SELECT dtt.stmpdate, intime
FROM #datetemp dtt left join
(
SELECT stmpdate, intime
FROM v_dayTimesheet
WHERE (emp_no = '001234567')
) as vdayTimesheet
on sparedate.stmpdate=vdayTimesheet.stampdate
ORDER BY stmpdate
this is what I want, thanks everyone

SQL Query:
SQLFIDDLEExample
SELECT t2.dt,
isnull(t1.intime, '') intime
FROM
(
SELECT DATEADD(day,number,'2014-10-01') dt
FROM master..spt_values
WHERE Type = 'P'
AND DATEADD(day,number,'2014-10-01') >= '2014-10-01'
AND DATEADD(day,number,'2014-10-01') < '2014-11-01'
) t2
LEFT JOIN Table1 t1
ON t1.stmpdate = t2.dt
Result:
| DT | INTIME |
