I am trying to find a way to convert this table I have that has sorted everything in columns into rows
EmpID Day StartTime
-------------------------------------------------
4 SUNDAY 10:00:00 AM
4 MONDAY 8:00:00 AM
4 TUESDAY 8:00:00 AM

800 WEDNESDAY 8:00:00 AM
800 THURSDAY 8:00:00 AM
800 FRIDAY NULL
800 SATURDAY NULL
INTO
EmpID Sunday(Start Time) Monday(Start Time)
-------------------------------------------------
4 10:00:00 AM 8:00:00 AM
etc...
I've seen examples of Pivot and Unpivot, but would this be to complex for the pivot/unpivot function?
If you want to use PIVOT
Example
Select *
From YourTable src
Pivot ( max(StartTime) for Day in ([Sunday],[Monday],[Tuesday] ) ) pvt
Note: This assumes YourTable is the 3 columns as displayed in your sample. If you have extra columns, YourTable should be replaced with a sub-query such as
From (Select EmpID,Day,StartTime From YourTable) src
I would just use conditional aggregation:
select empid,
max(case when day = 'Sunday' then StartTime end) as Sunday_StartTime,
max(case when day = 'Monday' then StartTime end) as Monday_StartTime,
. . .
from t
group by empid;

I have this query for Employee's fingerprints
SELECT

to_char(vahruae_timeofattendance, 'hh:mi') Time
FROM vahruae_hr_empattendancelog empl
INNER JOIN c_bpartner bp ON empl.vahruae_enroll_id = bp.enroll_id
And the value displays as follows
Name Date Time

John 01-SEP-2022 1:00
John 01-SEP-2022 9:00
John 01-SEP-2022 13:00

Ali 01-SEP-2022 10:00 (null) (null) (null)
Ali 05-SEP-2022 5:00 (null) (null) (null)
I'm not very good with Pivot, but I know I cannot use a subquery inside the Pivot IN Clause.
How can I accomplish that?
Use the ROW_NUMBER analytic function to index the times within a sub-query and then PIVOT using that:
SELECT name,
dt,
time1,
time2,
time3,
time4
FROM (
SELECT empl.vahruae_enroll_id,
bp.Name,
vahruae_date AS dt,
to_char(vahruae_timeofattendance, 'hh:mi') AS Time,
ROW_NUMBER() OVER (
PARTITION BY empl.vahruae_enroll_id,
vahruae_date,
TRUNC(vahruae_timeofattendance)
ORDER BY vahruae_timeofattendance
) AS rn
FROM vahruae_hr_empattendancelog empl
INNER JOIN c_bpartner bp
ON empl.vahruae_enroll_id = bp.enroll_id
)
PIVOT (
MAX(time)
FOR rn IN (1 AS time1, 2 AS time2, 3 AS time3, 4 AS time4)
)
We need to number the hours by date and name using row_number() and then pivoting.
select *
from
(
select "Name" as "Name"
,to_char("Date", 'hh24:mi') as "Time"
,to_date(to_char("Date", 'DD-mon-YYYY')) as "Date"
,row_number() over(partition by "Name", to_char("Date", 'DD-mon-YYYY') order by to_char("Date", 'hh24:mi')) as rn
from t
) t
pivot(max("Time") for rn in('1' as Time1, '2' as Time2, '3' as Time3, '4' as Time4)) p
order by "Name" desc, "Date"
Name

Have scenario to select unique value present in tracking table for a given time
Table values like,
HistoryId EmpId RoleName TimeStamp
1 1 Developer 8:00:00 AM
2 1 Lead 8:00:00 PM
3 1 Mgr 5:00:00 PM
4 2 Lead 8:00:00 AM
5 2 Developer2 5:00:00 PM
6 2 Mgr2 8:00:00 PM
7 3 Mgr 8:00:00 AM
8 3 Lead2 5:00:00 PM
9 3 Developer3 8:00:00 PM
11 3 Developer4 8:30:00 PM
12 1 lead5 8:15:00 PM
Want to select the unique RoleName values for user for a given time,
Example - If I pass time as 6PM, it should select latest status of each user at 6PM
I have tried to select as below, but it is given all the values, where as I need only latest values present for the time value passed
Select EmpId, RoleName, MAX(TimeStamp)
From [dbo].[EmpRoleHistory]
Where TimeStamp <= '2020-02-06 18:00:00.000'
GROUP BY EmpId, RoleName
ORDER BY EmpId
Expected Result:
1 Mgr 2020-02-06 17:00:00.000
2 Developer2 2020-02-06 17:00:00.000
3 Lead2 2020-02-06 17:00:00.000
Current Result:
1 Developer 2020-02-06 08:00:00.000
1 Mgr 2020-02-06 17:00:00.000
2 Developer2 2020-02-06 17:00:00.000
2 Lead 2020-02-06 08:00:00.000
3 Lead2 2020-02-06 17:00:00.000
3 Mgr 2020-02-06 08:00:00.000
The problem is here
GROUP BY EmpId, RoleName
As I can see, the same EmpId have different from RoleName.
So that's the reason why you are getting different values.

;with cte_TempTable as

GROUP BY EmpId
)
select e.*
from EmpRoleHistory e
inner join cte_TempTable c on e.EmpId = c.EmpId
where e.TimeStamp = c.TimeStamp
ORDER BY e.EmpId
Output
Use a subquery and not exists
with cte as
(
Select EmpId, RoleName, TimeStamp
From [dbo].[EmpRoleHistory]

)
select * from cte a
where not exists
(
select 1 from cte b where a.EmpId= b.EmpId and a.TimeStamp < b.TimeStamp
)
Use a subquery or CTE to return the latest EmpRoleHistory record for each employee prior to the supplied datetime, and then join the subquery to the main table to pull out the RoleName value for those records.
Select erh.EmpId, erh.RoleName, erh.TimeStamp
From [dbo].[EmpRoleHistory] as erh
Inner Join (
Select EmpId, MAX(TimeStamp) as TimeStamp
From [dbo].[EmpRoleHistory]
Where TimeStamp <= '2020-02-06 18:00:00.000'
GROUP BY EmpId
) as filt on erh.EmpId = filt.EmpId and
erh.TimeStamp = filt.TimeStamp
Order By erh.EmpId

To get the number of hours worked for an employee within a particular week, just use a suitable WHERE criteria. No need to use DENSE_RANK or similar windowed functions for this.
Assuming you have a #Week parameter, that contains an integer (0 for current week, 1 for last week, 2 for week before that, etc.):
SELECT
employee_id
SUM(ROUND(CAST(DATEDIFF(MINUTE, start_time, finish_time) AS NUMERIC(18, 0)) / 60, 2)) AS total_h
FROM
Timesheet t
WHERE
t.employee_id = #employee_id AND
date_worked BETWEEN DATEADD(ww, DATEDIFF(ww,0,GETDATE()) - #Week, 0)
AND DATEADD(ww, DATEDIFF(ww,0,GETDATE()) - #Week, 0) + 7
Here, I've used the current date (GETDATE()) as the base date, but you could just replace it with 20130925, if that's what you need.
I would like to get the count of every day records from my table.
For example I have a table “Employee” with the following fields ID, EmpNo, DateHired.

You need to create a calendar for the whole month of April in order to get the whole dates of the month. With the aid of using Common Table Expression, you can get what you want.
After creating a calendar, join it with table Employee using LEFT JOIN so dates will have no matches on table Employee will still be included on the result.
WITH April_Calendar
AS
(
SELECT CAST('20130401' as datetime) AS [date]
UNION ALL
SELECT DATEADD(dd, 1, [date])
FROM April_Calendar
WHERE DATEADD(dd, 1, [date]) <= '20130430'
)
SELECT a.date, COUNT(b.DateHired) totalCount
FROM April_Calendar a
LEFT JOIN Employee b
ON a.date = b.DateHired
GROUP BY a.date
ORDER BY a.date

Try
SELECT COUNT(*) as 'Count', DateHired as 'Day'
FROM Employee
WHERE DateHired BEWTEEN %date1 AND %date2
GROUP BY DateHired
Untested, should work though.
This could be the query...
SELECT COUNT(ID) as Count, DateHired FROM Employee GROUP BY DateHired
Following can be helpful in the case...
