How to convert rows in columns - sql

Question

I have some problems with a SQL query, I try to convert row in columns.
select U.FirstName,U.LastName,Sh.[Day],Sh.StartTime,Sh.EndTime from dbo.[User] as U
inner join dbo.Employee as E on U.UserId = E.UserId
inner join dbo.ScheduleStaff as SH on SH.EmployeeId = E.EmployeeId
where ((Sh.[Day] < getdate()+ 4 ) and sh.[Day] >= getdate())
group by U.FirstName, U.LastName,Sh.[Day],Sh.StartTime,Sh.EndTime
This query gives me the below result:
How can I make that there is one employee per line, and the days turn into columns?
I try this:
select FirstName,LastName,Day1,Day2,Day3
from
(
select U.FirstName,U.LastName,Sh.[Day],Sh.StartTime,Sh.EndTime,concat('Day',ROW_NUMBER() over (partition by
U.FirstName,U.LastName order by U.FirstName,U.LastName)) as Tests
from dbo.[User] as U
inner join dbo.Employee as E on U.UserId = E.UserId
inner join dbo.ScheduleStaff as SH on SH.EmployeeId = E.EmployeeId
where ((Sh.[Day] < getdate()+ 4 ) and sh.[Day] >= getdate()-1)
group by U.FirstName, U.LastName,Sh.[Day],Sh.StartTime,Sh.EndTime
)Temp
pivot
(
Max([Day])
for Tests in (Day1,Day2,Day3)
)Piv
But this is not exactly what I need, how can I make the days as columns and their time as values?

Answer 1

This will work if you have static [Date] value. But if you want [Date] dynamic then you need to collect date value and put into pivot section.
Your question was[how can I make the days as columns and their time as values]
select FirstName,LastName,[2020-08-28],[2020-08-29] from
(select FirstName,LastName,[Date], CONCAT(StartTime,'-to-'+EndTime) as [Time] from tbl_user) t
pivot(MAX(t.[Time]) for [Date] in([2020-08-28],[2020-08-29]) )pvt
Note: for dynamic date value. You can follow Terence link mentioned in comment section.
