Data Partition View

Hi ,
I have question regard data partition view .

Please see below sample from BOL + sample of execution plane .

I would like to ask what is the way to avoid the optimizer scan tables out of the scope (I would expect that the only table for this query will be SUPPLY1)

Thanks,
Eyal




--This example uses tables named SUPPLY1, SUPPLY2, SUPPLY3, and SUPPLY4, which correspond to the supplier tables from four offices, located in different countries/regions.
USE tempdb
GO


--create the tables and insert the values
CREATE TABLE SUPPLY1 (
supplyID INT PRIMARY KEY CHECK (supplyID BETWEEN 1 and 150),
supplier CHAR(50)
)
CREATE TABLE SUPPLY2 (
supplyID INT PRIMARY KEY CHECK (supplyID BETWEEN 151 and 300),
supplier CHAR(50)
)
CREATE TABLE SUPPLY3 (
supplyID INT PRIMARY KEY CHECK (supplyID BETWEEN 301 and 450),
supplier CHAR(50)
)
CREATE TABLE SUPPLY4 (
supplyID INT PRIMARY KEY CHECK (supplyID BETWEEN 451 and 600),
supplier CHAR(50)
)
GO
--create the view that combines all supplier tables
CREATE VIEW all_supplier_view
AS
SELECT *
FROM SUPPLY1
UNION ALL
SELECT *
FROM SUPPLY2
UNION ALL
SELECT *
FROM SUPPLY3
UNION ALL
SELECT *
FROM SUPPLY4
GO

INSERT all_supplier_view VALUES ('1', 'CaliforniaCorp')
INSERT all_supplier_view VALUES ('5', 'BraziliaLtd')
INSERT all_supplier_view VALUES ('231', 'FarEast')
INSERT all_supplier_view VALUES ('280', 'NZ')
INSERT all_supplier_view VALUES ('321', 'EuroGroup')
INSERT all_supplier_view VALUES ('442', 'UKArchip')
INSERT all_supplier_view VALUES ('475', 'India')
INSERT all_supplier_view VALUES ('521', 'Afrique')

GO

SELECT * FROM all_supplier_view WHERE supplyID BETWEEN 1 and 150
