How Can I Order in an SQL Statement? - sql-server

Question

I have these tables: Stock, Unit, Location, Category, StockBalance
At StockBalance: there is StockID from Stock, UnitId from Unit, LocationID from Location
I save at StockBalance Table like following
StockBalanceID | StockID | UnitID | LocationID | BalanceQuantity
1 | 1 | 1 | 1 | 20
2 | 1 | 2 | 1 | 30
3 | 1 | 3 | 1 | 40
4 | 2 | 1 | 2 | 20
5 | 2 | 2 | 2 | 30
6 | 2 | 3 | 2 | 40
I would like to show on Classic ASP as :
Group By : CategoryName
Stock Name Quantity Location Name
Qty | Unit | Qty | Unit | Qty | Unit
Stock One | 20 | One | 30 | Two | 40 | Three | Location One
Stock Two | 20 | One | 30 | Two | 40 | Three | Location Two
How can I Select From StockBalance to get like above? How about my edit one?
Please help me !

Answer 1

PIVOT is what you want.
First some sample data setup:
create table yourTable (
StockBalanceID int, StockID int, UnitID int, LocationID int, BalanceQuantity int);
insert yourTable
select 1 , 1 , 1 , 1 , 20
union all select 2 , 1 , 2 , 1 , 30
union all select 3 , 1 , 3 , 1 , 40
union all select 4 , 2 , 1 , 2 , 20
union all select 5 , 2 , 2 , 2 , 30
union all select 6 , 2 , 3 , 2 , 40
;
Now to do the work...
select StockID, LocationID,
sum(case UnitID when 1 then BalanceQuantity end) as [Unit One],
sum(case UnitID when 2 then BalanceQuantity end) as [Unit Two],
sum(case UnitID when 3 then BalanceQuantity end) as [Unit Three]
from yourTable
group by StockID, LocationID;

Answer 2

Try the following
DECLARE #StockBalances TABLE(
StockBalanceID INT,
StockID INT,
UnitID INT,
LocationID INT,
BalanceQuantity FLOAT
)
DECLARE #Stock TABLE(
StockID INT,
StockName VARCHAR(10)
)
DECLARE #Unit TABLE(
UnitID INT,
UnitName VARCHAR(10)
)
DECLARE #Location TABLE(
LocationID INT,
LocationName VARCHAR(10)
)
INSERT INTO #StockBalances SELECT 1,1,1,1,20
INSERT INTO #StockBalances SELECT 2,1,2,1,30
INSERT INTO #StockBalances SELECT 3,1,3,1,40
INSERT INTO #StockBalances SELECT 4,2,1,2,20
INSERT INTO #StockBalances SELECT 5,2,2,2 ,30
INSERT INTO #StockBalances SELECT 6,2,3,2,40
INSERT INTO #Stock SELECT 1, 'Stock 1'
INSERT INTO #Stock SELECT 2, 'Stock 2'
INSERT INTO #Unit SELECT 1, 'Unit 1'
INSERT INTO #Unit SELECT 2, 'Unit 2'
INSERT INTO #Unit SELECT 3, 'Unit 3'
INSERT INTO #Location SELECT 1, 'Location 1'
INSERT INTO #Location SELECT 2, 'Location 2'
SELECT *
FROM (
SELECT s.StockName,
sb.BalanceQuantity,
u.UnitName,
l.LocationName
FROM #StockBalances sb INNER JOIN
#Stock s ON sb.StockID = s.StockID INNER JOIN
#Unit u ON sb.UnitID = u.UnitID INNER JOIN
#Location l ON sb.LocationID = l.LocationID
) t
PIVOT (SUM(BalanceQuantity) FOR UnitName IN ([Unit 1], [Unit 2], [Unit 3])) p
