How to Format SQL Query? Use Pivot? - sql-server

Question

Here is my Query. The results that I get are correct but I'm having trouble getting it in the desired format. I've tried to use Pivot, but I get errors. Any ideas?
Query:
DECLARE #SMonth DATETIME
SET #SMonth = '12/01/2015'
SELECT
SMonth 'Sales Month',
c.CustNumber 'Customer',
b.Description 'Brand',
Sum (SaleQuantity) 'Qty'
FROM
DistStructure.Customer c
JOIN Sales.Sale s ON s.CustId = c.CustId
JOIN Sales.Import i on i.ImportRefId = s.ImportRefId
JOIN AppSecurity.Log l on l.LogId = s.ImportRefId
JOIN Sales.Prod p on p.ProdId = s.ProdId
JOIN Sales.Brand b on b.BrandId = p.BrandId
WHERE
s.SMonth = #SMonth AND
i.ImportStatId = 50
Group By
CustNumber,
SMonth,
Description
Order By
CustNumber
Query Results:
Sales Month Customer Brand Qty

2015-12-01 00:00:00.000 034983 FZ 3
Desired Format:
Note: The Customer should be rolled up by Brand (so there is only one row per Customer) and then totaled. If the Brand has no data a zero should be placed in the spot.

Answer 1

Here is one way using Conditional Aggregate to alter your existing query to get the desired result format.
;with cte as
(
SELECT [Sales Month]=SMonth,
[Customer]= c.CustNumber,
[BS] = Sum(CASE WHEN b.Description = 'BS' THEN SaleQuantity ELSE 0 END),
[FS]= Sum(CASE WHEN b.Description = 'FS' THEN SaleQuantity ELSE 0 END),
[FZ]= Sum(CASE WHEN b.Description = 'FZ' THEN SaleQuantity ELSE 0 END)
FROM DistStructure.Customer c
JOIN Sales.Sale s
ON s.CustId = c.CustId
JOIN Sales.Import i
ON i.ImportRefId = s.ImportRefId
JOIN AppSecurity.Log l
ON l.LogId = s.ImportRefId
JOIN Sales.Prod p
ON p.ProdId = s.ProdId
JOIN Sales.Brand b
ON b.BrandId = p.BrandId
WHERE s.SMonth = #SMonth
AND i.ImportStatId = 50
GROUP BY CustNumber,
SMonth
ORDER BY [Customer]
)
SELECT [Sales Month],
[Customer],
[BS],
[FS],
[FZ],
TOTAL=[BS] + [FS] + [FZ]
FROM CTE
Note: If number of Brand's are unknown then you need to use dynamic code

I believe this is what you are looking for:
/*
Setup Sample Table
*/
declare #t table
(
[Sales Month] datetime,
Customer nvarchar(6),
Brand nvarchar(2),
Qty tinyint
)
/*
Setup Sample Table with
*/
insert into #t
([Sales Month], Customer, Brand, Qty)
values ('2015-12-01', '030554', N'FS', 29),
('2015-12-01', '030554', N'BS', 5),
('2015-12-01', '032204', N'FZ', 21),
('2015-12-01', '032204', N'BS', 14),
('2015-12-01', '032204', N'FS', 114),
('2015-12-01', '034312', N'FZ', 8),
('2015-12-01', '034312', N'FS', 104),
('2015-12-01', '034312', N'BS', 16),
('2015-12-01', '034983', N'FS', 63),
('2015-12-01', '034983', N'BS', 18),
('2015-12-01', '034983', N'FZ', 3)
/*
Generating desired output
*/
select pvt.[Sales Month],
pvt.Customer,
isnull(pvt.BS, 0) as BS,
isnull(pvt.FS, 0) as FS,
isnull(pvt.FZ, 0) as FZ,
isnull(pvt.BS, 0) + isnull(pvt.FS, 0) + isnull(pvt.FZ, 0) as Total
from #t as t pivot
( sum(Qty) for Brand in (BS, FS, FZ) ) as pvt
