Constructing a View into time dependant data

Question

1. I have a table with data like this:
PersonID
DateTime
Temperature
Pressure
2. I want to build a view into this table so that it shows up as follows:
PersonID    DateTime1            DateTime2             DateTime3         .....
1                Pressure1              Pressure2                Pressure3        ......
1                Temperature1        Temperature2          Tempearture3  .....
2                :
how would I do this?

Answer 1

Below query will work above SQL 2005,
--create table routineCheck(PersonID int, [datetime] datetime, Temperature int, Pressure int)
--insert into routineCheck values
--(1,'01/01/2014', 61, 55),
--(2,'02/01/2014', 60, 52),
--(1,'01/05/2014', 62, 53),
--(3,'01/08/2014', 60, 55),
--(1,'02/07/2014', 63, 54),
--(2,'01/12/2014', 63, 55)
declare @cols nvarchar(max)
declare @stmt nvarchar(max)
select @cols = isnull(@cols + ', ', '') + '[' + cast(T.[datetime] as varchar)+ ']' from (select distinct [datetime] from routineCheck) as T
print @cols
select @stmt = '
select *
from (select PersonID, [datetime], Temperature from routineCheck) as T
pivot
max(T.temperature)
for T.[datetime] in (' + @cols + ')
) as P '
select @stmt = @stmt + ' union all
select *
from (select PersonID, [datetime], Pressure from routineCheck) as T
pivot
max(T.pressure)
for T.[datetime] in (' + @cols + ')
) as P1 order by PersonID'
exec sp_executesql @stmt = @stmt
