SQL Pivot Half of table - sql

Question

I have a table that consists of time information. It's basically:
Employee, Date, Seq, Time In, Time Out.
They can clock out multiple times a day, so I'm trying to get all of the clock outs in a day on one row. My result would be something like:
Employee, Date, TimeIn1, TimeOut1, TimeIn2, TimeOut2, TimeIn3, TimeOut3....
Where the 1, 2, and 3 are the sequence numbers. I know I could just do a bunch of left joins to the table itself based on employee=employee, date=date, and seq=seq+1, but is there a way to do it in a pivot? I don't want to pivot the employee and date fields, just the time in and time out.

Answer 1

The short answer is: Yes, it's possible.
The exact code will be updated if/when you provide sample data to clarify some points, but you can absolutely pivot the times out while leaving the employee/work date alone.
Sorry for the wall of code; none of the fiddle sites are working from my current computer
declare #test table (
pk int,
workdate date,
seq int,
tIN time,
tOUT time
)
insert into #test values
(1, '2020-11-25', 1, '08:00', null),
(1, '2020-11-25', 2, null, '11:00'),
(1, '2020-11-25', 3, '11:32', null),
(1, '2020-11-25', 4, null, '17:00'),
(2, '2020-11-25', 5, '08:00', null),
(2, '2020-11-25', 6, null, '09:00'),
(2, '2020-11-25', 7, '09:15', null),
-- new date
(1, '2020-11-27', 8, '08:00', null),
(1, '2020-11-27', 9, null, '08:22'),
(1, '2020-11-27', 10, '09:14', null),
(1, '2020-11-27', 11, null, '12:08'),
(1, '2020-11-27', 12, '01:08', null),
(1, '2020-11-27', 13, null, '14:40'),
(1, '2020-11-27', 14, '14:55', null),
(1, '2020-11-27', 15, null, '17:00')
select *
from (
/* this just sets the column header names and condenses their values */
select
pk,
workdate,
colName = case when tin is not null then 'TimeIn' + cast(empDaySEQ as varchar) else 'TimeOut' + cast(empDaySEQ as varchar) end,
colValue = coalesce(tin, tout)
from (
/* main query */
select
pk,
workdate,
/* grab what pair # this clock in or out is; reset by employee & date */
empDaySEQ = (row_number() over (partition by pk, workdate order by seq) / 2) + (row_number() over (partition by pk, workdate order by seq) % 2),
tin,
tout
from #test
) i
) a
PIVOT (
max(colValue)
for colName
IN ( /* replace w/ dynamic if you don't know upper boundary of max in/out pairs */
[TimeIn1],
[TimeOut1],
[TimeIn2],
[TimeOut2],
[TimeIn3],
[TimeOut3],
[TimeIn4],
[TimeOut4]
)
) mypivotTable
generates these results.
(I would provide a fiddle demo but they're not working for me today)
