Need SQL pivot assistance as I do not have an aggregate column - sql

Question

I have the following view I created that looks like this table.
Create Table #Temptable(
[Week number] int,
[Did Not meet minimum] int,
[Met minimum] int,
[exceeded minimum] int);
insert into #Temptable([Week number],[Did Not meet minimum],[Met minimum],[exceeded minimum])
values
(3,161,4,18),
(4,165,1,24),
(5,166,0,10)
I would like the output to be three lines so that I can create a trending report by week. I can populate a temp table to get the desired result but I would like to see if there is a better solution.
Label, week3, week4, week5
Did not meet minimum, 161, 165, 166
Met minimum, 4, 1, 0
Exceeded minimum, 18, 24, 10
If this is not possible from this data set I also have the source line item detail the view was created from. that dataset looks like this
techname,machinename,installdate,weeknumber
I made 3 scalar functions that aggregate by techname and week number so that I can get the Did not meet, Met, and exceeded install counts for each week.
Thank you in advance.
After getting the response from StuartLC I began to craft my own dynamic version I was close but as I was posting a response another kind person posted a working version. For everyone's benefit here is the sample code I put together it however is not working. If I copy the error text and just select the outputted query it does work properly.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(c.[week number])
FROM SummarisedWeeklysums c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Criteria, '+ #Cols +' FROM
(
SELECT
*
FROM
SummarisedWeeklysums
UNPIVOT
(
CriteriaCount
for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum])
) unpvt
) X
PIVOT
(
SUM(CriteriaCount)
for [Week Number] IN ('+#Cols+')
)pvt'
execute #query

Answer 1

This is quite similar to my answer here - basically you are looking for a full transpose. This can be done with an unpivot, followed by a pivot:
SELECT Criteria, [3] as Week3, [4] AS Week4, [5] AS Week5
FROM
(
SELECT
*
FROM
#Temptable
UNPIVOT
(
CriteriaCount
for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum])
) unpvt
) X
PIVOT
(
SUM(CriteriaCount)
for [Week Number] IN ([3],[4],[5])
)pvt;
Fiddle here
Also, if you need to do this for a bunch of unknown weeks (or criteria, I guess), you can look at the answer here which uses dynamic sql to build up the columns and execute the pivot.

Answer 2

The is based on StuartLC answer and link (credit to you) with scalability if extra weeks are added in the future:
DECLARE #cols AS NVARCHAR(MAX);
DECLARE #query AS NVARCHAR(MAX);
select #cols = STUFF((SELECT distinct ',' +
QUOTENAME('Week'+cast([Week Number] as varchar))
FROM #Temptable
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
select #query =
'SELECT *
FROM
(
SELECT
''Week''+cast([Week number] as varchar) as [Week number] , CriteriaCount , Criteria
FROM
#Temptable
UNPIVOT
(
CriteriaCount
for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum])
) unpvt
) X
PIVOT
(
SUM(CriteriaCount)
for [Week Number] in (' + #cols + ')
)pvt ;';
execute(#query);
Below is the same code, with the results moved into a temp table (as requested by user3275636) and then displayed:
DECLARE #cols AS NVARCHAR(MAX);
DECLARE #query AS NVARCHAR(MAX);
select #cols = STUFF((SELECT distinct ',' +
QUOTENAME('Week'+cast([Week Number] as varchar))
FROM #Temptable
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
select #query =
'select * into ##temp1 from (SELECT *
FROM
(
SELECT
''Week''+cast([Week number] as varchar) as [Week number] , CriteriaCount , Criteria
FROM
#Temptable
UNPIVOT
(
CriteriaCount
for Criteria in ([Did Not meet minimum],[Met minimum],[exceeded minimum])
) unpvt
) X
PIVOT
(
SUM(CriteriaCount)
for [Week Number] in (' + #cols + ')
)pvt ) as combi;';
execute(#query);
select * from ##temp1;
