Sql - Row as column - sql

Question

I have data in below format, around 8 to 9 departments, for each department few questions.
| Department | NoOfCases | Question | Rate |
+============+===========+==========+======+
| VC | 4 | A | 80 |
| VC | 2 | B | 90 |
| VC | 1 | C | 95 |
| ED | 5 | A | 85 |
| ED | 1 | B | 90 |
| ED | 3 | C | 95 |
| PH | 3 | A | 80 |
I want into below format, I want total no of cases per department and every question as column and rate as its value.
| Department | NoOfCases | A | B | C(actual questions as columns) |
+============+===========+====+====+================================+
| VC | 7 | 80 | 90 | 95 |
| ED | 9 | 85 | 90 | 95 |
| PH | 3 | 80 | | |
Can we achieve this?

Answer 1

You can achieve it using a PIVOT with a GROUP BY:
--create table variable to hold sample data
declare #tmp table( Department nvarchar(2),NoOfCases int, Question nvarchar(1), Rate int)
--populate sample data
insert into #tmp select 'VC', 4,'A', 80
insert into #tmp select 'VC', 2,'B', 90
insert into #tmp select 'VC', 1,'C', 95
insert into #tmp select 'ED', 5,'A', 85
insert into #tmp select 'ED', 1,'B', 90
insert into #tmp select 'ED', 3,'C', 95
insert into #tmp select 'PH', 3,'A', 80
select * from #tmp
--pivot with group by
select Department,SUM(piv.NoOfCases) AS NoOfCases,
ISNULL(SUM(A),0) AS A, ISNULL(SUM(B),0) AS B, ISNULL(SUM(C),0) AS C
from
(
--select data
select Department,NoOfCases , Question ,RATE
from #tmp
) src
pivot
(
MAX(RATE)
for Question in ([A], [B], [C])
) piv
GROUP BY Department
This is the output of the command:
