Big thanks to @JohnCappelletti as he's shown how to pivot a table.
This is a sample data:
DECLARE @OperatorPrice TABLE (ID int NOT NULL, OperatorId INT NULL, Price
NUMERIC(18,3) NULL, FName VARCHAR(50) NULL)
INSERT INTO @OperatorPrice (
ID, OperatorId, Price, FName
)
VALUES
(226, 996, 22954,'Operator1')
, (266, 1016, 79011.2, 'Operator3')
, (112, 1029, 14869, 'Operator4')
, (112, 996, 22954, 'Operator1')
, (93, 1031, 10568.96, 'Operator5')
DECLARE @TR TABLE
(
ID varchar(25) NULL
, MinPrice DECIMAL(18,3) NULL, MaxPrice DECIMAL(18,3) NULL
, SumCount DECIMAL(18,3) NULL
, Operator1 DECIMAL(18,3) NULL, OC1 DECIMAL(18,3) NULL, Operator2
DECIMAL(18,3) NULL,
OC2 DECIMAL(18,3) NULL, Operator3 DECIMAL(18,3) NULL, OC3
DECIMAL(18,3) NULL,
Operator4 DECIMAL(18,3) NULL, OC4 DECIMAL(18,3) NULL, Operator5
DECIMAL(18,3) NULL,
OC5 DECIMAL(18,3) NULL
)
The pivot code:
INSERT @TR
SELECT *
FROM (
Select B.*
From @OperatorPrice A
Cross Apply ( values (0,FName,Price)
, (0,'OC'+replace(FName,'Operator',''),OperatorID)
, (A.ID,'MinPrice', A.Price)
, (A.ID,'MaxPrice', A.Price)
, (A.ID,'SumCount', A.OperatorId)
, (A.ID,FName,Price)
, (A.ID,'OC'+replace(FName,'Operator',''),OperatorID)
) B (ID,Item,Value)
Union All
Select
ID=0
, B.*
From ( Select Top 50 N=Row_Number() Over (Order By (Select NULL))
From master..spt_values n1 ) A
Cross Apply ( values (concat('Operator',N),NULL)
,(concat('OC',N),NULL)
) B (Item,Value)
) AS SourceTable
PIVOT ( sum(Value) FOR Item IN (MinPrice, MaxPrice, SumCount,Operator1,
OC1, Operator2, OC2,
Operator3, OC3, Operator4, OC4, Operator5, OC5) ) AS PivotTable
SELECT * FROM @TR
The above code works perfectly, except MinPrice
and MaxPrice
are wrong! Currently they are Sum()
of Price
:
But I need Min()
of price and Max()
of Price
column. So the desired output should looks like this:
How to get Min()
of price and Max()
of Price
column for the row of pivoted table?
Gordon is correct, since you are mixing aggregations, the conditional aggregation may be more performant.
However, by adding a couple of UNION ALLs
we can get the desired results
Example
DECLARE @OperatorPrice TABLE (ID int NOT NULL, OperatorId INT NULL, Price
NUMERIC(18,3) NULL, FName VARCHAR(50) NULL)
INSERT INTO @OperatorPrice (
ID, OperatorId, Price, FName
)
VALUES
(226, 996, 22954,'Operator1')
, (266, 1016, 79011.2, 'Operator3')
, (112, 1029, 14869, 'Operator4')
, (112, 996, 22954, 'Operator1')
, (93, 1031, 10568.96, 'Operator5')
DECLARE @TR TABLE
(
ID varchar(25) NULL
, MinPrice DECIMAL(18,3) NULL, MaxPrice DECIMAL(18,3) NULL
, SumCount DECIMAL(18,3) NULL
, Operator1 DECIMAL(18,3) NULL, OC1 DECIMAL(18,3) NULL, Operator2
DECIMAL(18,3) NULL,
OC2 DECIMAL(18,3) NULL, Operator3 DECIMAL(18,3) NULL, OC3
DECIMAL(18,3) NULL,
Operator4 DECIMAL(18,3) NULL, OC4 DECIMAL(18,3) NULL, Operator5
DECIMAL(18,3) NULL,
OC5 DECIMAL(18,3) NULL
)
INSERT @TR
SELECT *
FROM (
Select B.*
From @OperatorPrice A
Cross Apply ( values (0,FName,Price)
, (0,'OC'+replace(FName,'Operator',''),OperatorID)
, (A.ID,'SumCount', A.OperatorId)
, (A.ID,FName,Price)
, (A.ID,'OC'+replace(FName,'Operator',''),OperatorID)
) B (ID,Item,Value)
Union All
Select ID,Item='MinPrice',Value=min(Price) From @OperatorPrice Group By ID
Union All
Select ID,Item='MaxPrice',Value=max(Price) From @OperatorPrice Group By ID
Union All
Select 0,Item='MinPrice',Value=min(Price) From @OperatorPrice
Union All
Select 0,Item='MaxPrice',Value=max(Price) From @OperatorPrice
Union All
Select 0,Item='SumCount',Value=sum(OperatorId) From @OperatorPrice
Union All
Select
ID=0
, B.*
From ( Select Top 50 N=Row_Number() Over (Order By (Select NULL))
From master..spt_values n1 ) A
Cross Apply ( values (concat('Operator',N),NULL)
,(concat('OC',N),NULL)
) B (Item,Value)
) AS SourceTable
PIVOT ( sum(Value) FOR Item IN (MinPrice, MaxPrice, SumCount,Operator1,
OC1, Operator2, OC2,
Operator3, OC3, Operator4, OC4, Operator5, OC5) ) AS PivotTable
SELECT * FROM @TR
Returns
Note: I added the Total Min, Max, SumCount for ID 0
You can wrap your entire code with the following:
SELECT CASE WHEN MinPrice IS NOT NULL THEN Mn END MinPrice,
CASE WHEN MaxPrice IS NOT NULL THEN Mx END MaxPrice,
SumCount , Operator1 , OC1 , Operator2 , OC2 , Operator3 , OC3 ,Operator4 , OC4 ,Operator5 , OC5
FROM
