SQL Federation 实验

第一步，创建表

CREATE DATABASE SalesDB
GO

第二步，连接到SalesDB，创建Federation
--

CREATE FEDERATION CustomerFederation(cid BIGINT RANGE)
GO
-- Connect to the federation member
USE FEDERATION CustomerFederation(cid = 0) WITH FILTERING=OFF, RESET
GO
CREATE TABLE [dbo].[Customer](
	[CustomerID] [bigint] NOT NULL,
	[Title] [nvarchar](18) NULL
 CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED ([CustomerID] ASC) 
) FEDERATED ON (cid = CustomerID)
GO
CREATE TABLE [dbo].[CustomerAddress](
	[AddressID] [int] NOT NULL,
	[CustomerID] [bigint] NOT NULL,
	[AddressName]  [nvarchar](80) NULL
 	CONSTRAINT [PK_CustomerAddress] PRIMARY KEY CLUSTERED ([CustomerID],[AddressID] ASC)
) FEDERATED ON (cid = CustomerID)
GO
CREATE TABLE [dbo].[PostalCode](
	[PostalCodeID] [int] NOT NULL,
	[PostalCode] [nvarchar](15) NOT NULL
	 CONSTRAINT [PK_PostalCode] PRIMARY KEY CLUSTERED ([PostalCodeID] ASC)
)
GO

第三步，写入数据

USE FEDERATION CustomerFederation(cid = 0) WITH FILTERING=OFF, RESET
GO
Insert into [Customer](CustomerID,Title) values(999,'Symbio')
Insert into [Customer](CustomerID,Title) values(1000,'MS')
Insert into [Customer](CustomerID,Title) values(1001,'ABB1')
GO
Insert into [CustomerAddress]([AddressID],[CustomerID],[AddressName])   values(1,999,'Symbio Address')
Insert into [CustomerAddress]([AddressID],[CustomerID],[AddressName])   values(2,1000,'MS Address')
Insert into [CustomerAddress]([AddressID],[CustomerID],[AddressName])   values(3,1001,'ABB1 Address')
GO
Insert into [PostalCode]([PostalCodeID],[PostalCode])  values(1,'95568')
Insert into [PostalCode]([PostalCodeID],[PostalCode])  values(2,'95569')
Insert into [PostalCode]([PostalCodeID],[PostalCode])  values(3,'95570')

第四步，拆分，连接到主库SalesDB
GO

ALTER FEDERATION CustomerFederation SPLIT AT(cid = 1000)

第五步，验证

USE FEDERATION CustomerFederation(cid = 999) WITH RESET, FILTERING=on
GO


select * from [Customer]
select * from [CustomerAddress]
select * from [PostalCode]
