SQL Query using Pivot - sql

Question

I have a table as follows:
PriorityText Priority LoRes Partial Unknown N_A HiRes
------------------------------------------------------------------
Very High 5 0.0612 0.0000 0.0612 0.0612 0.2041
High 4 0.1429 0.0000 0.1633 0.0000 0.1633
Medium 3 0.0000 0.0000 0.1020 0.0000 0.0408
Low-Medium 2 0.0000 0.0000 0.0000 0.0000 0.0000
Low 1 0.0000 0.0000 0.0000 0.0000 0.0000
I am tying to transpose the table into this:
PriorityText Low Low-Medium Medium High Very High
--------------------------------------------------------
Priority 1 2 3 4 5
LoRes 0 0 0 0.1429 0.0612
Partial 0 0 0 0 0
Unknown 0 0 0.102 0.1633 0.0612
N_A 0 0 0 0 0.0612
HiRes 0 0 0.0408 0.1633 0.2041
I am using SQL 2008. I am having trouble coming up with the SQL syntax to perform a pivot on the data.
Can someone please share a SQL snippet that will solve this for me?
I have used the following to successfully pivot one row, but I do not know how to make it do all my rows.
SELECT VeryHigh AS VeryHigh,
High AS High,
Medium AS Medium,
[Low-Medium] AS [Low-Medium],
Low AS Low
FROM (SELECT [PriorityText], [LoRes] FROM #tbTemp) p
PIVOT (SUM(LoRes) FOR [PriorityText] in ([VeryHigh], [High], [Medium], [Low-Medium], [Low])) pvt
My test data in my table is as follows:
Priority PriorityText LoRes Partial Unknown N_A HiRes
1 VeryHigh 0.05 11 54 0 9
2 High 0.14 22 54 0 3
3 Medium 0.07 33 65 0 7
4 Low-Medium 0.01 44 87 0 4
5 Low 0 55 9 0 0
NULL NULL NULL NULL NULL NULL NULL
Thank for any help!!

Not sure how hardcoded you can make this, but what your wanting to do is Transpose the Rows with the Columns.
SELECT p.[Type] as 'PriorityText', Low, [Low-Medium], Medium,High,[VeryHigh]
FROM (SELECT PriorityText, [Holder],[Type]
FROM (SELECT PriorityText,Priority,LoRes,[Partial],Unknown,N_A,HiRes
FROM Test) as sq_source
UNPIVOT ([Holder] FOR [Type] IN
(Priority,LoRes,[Partial],Unknown,N_A,HiRes)) as sq_up
) as sq
PIVOT (
MIN([Holder])
FOR PriorityText IN
(VeryHigh,High,Medium,[Low-Medium],Low)
) as p
order by CASE p.[Type] WHEN 'Priority' THEN 1
WHEN 'LoRes' THEN 2
WHEN 'Partial' THEN 3
WHEN 'Unknown' THEN 4
WHEN 'N_A' THEN 5
ELSE 6 END ASC;
This should get you what you need. One thing to note is this only works if the columns:
Priority
LoRes
Partial
Unknown
N_A
HiRes
are of the same data type (in my test it was decimal(5,4)). If yours are deferent then you will need to do an initial select and convert them to a common data type and use that as the sq_source.
