Creating Indexed View in Microsoft SQL Server 2005 & 2008

Indexed View is the one of the best solutions to Business users


use Northwind
go

sp_help Orders
sp_help Customers

select * from Customers
select * from Orders



-- Select data from two tables for test
select OrderID, OrderDate , Orders.CustomerID,CompanyName
from Orders Inner Join Customers
on Orders.CustomerID = Customers.CustomerID
go

-- Step 1

-- create view from joined two tables
create view [dbo].[vw_OrderbyCustomer] with schemabinding as
(
select [OrderID], [OrderDate] , [Orders].CustomerID, [CompanyName]
from [dbo].[Orders]
Inner Join [dbo].Customers on [Orders].CustomerID = [Customers].CustomerID
)
go

select * from [vw_OrderbyCustomer]


-- Step 2
-- create a Clustered Index on View
create unique clustered index Idx_CI_View_OrderId_CustomerId on [vw_OrderbyCustomer](OrderID,CustomerID)

-- check the Index from Tables
sp_helpIndex vw_OrderbyCustomer

-- create a NonClustered Index on View
create unique index Idx_NCI_View_OrderId on [vw_OrderbyCustomer](OrderID)
create index Idx_NCI_View_CustomerId on [vw_OrderbyCustomer](CustomerID)
create index Idx_NCI_View_OrderDate on [vw_OrderbyCustomer](OrderDate)
create index Idx_NCI_View_CompanyName on [vw_OrderbyCustomer](CompanyName)

-- Step 3
sp_helpIndex vw_OrderbyCustomer

Idx_CI_View_OrderId_CustomerId clustered, unique located on PRIMARY OrderID, CustomerID
Idx_NCI_View_CompanyName nonclustered located on PRIMARY CompanyName
Idx_NCI_View_CustomerId nonclustered located on PRIMARY CustomerID
Idx_NCI_View_OrderDate nonclustered located on PRIMARY OrderDate
Idx_NCI_View_OrderId nonclustered, unique located on PRIMARY OrderID
