SQL2005分区实例

-- 增加文件组
 Alter DataBase TEST ADD FILEGROUP [User01]
 ALTER DATABASE TEST 
   ADD FILE 
  (NAME = 'User01', 
   FILENAME = 'D:\SqlData\UserFS01.NDF',
   SIZE = 5MB,
   FILEGROWTH = 5MB) 
   TO FILEGROUP User01

 Alter DataBase TEST ADD FILEGROUP [User02]
 ALTER DATABASE TEST 
   ADD FILE 
  (NAME = 'User02', 
   FILENAME = 'D:\SqlData\UserFS02.NDF',
   SIZE = 5MB,
   FILEGROWTH = 5MB) 
   TO FILEGROUP User02

-- 增加分区范围
CREATE PARTITION FUNCTION [UserRange]
(int) AS RANGE RIGHT FOR VALUES
 (1000,1100)
go

-- 增加分区架构
CREATE PARTITION SCHEME [UserScheme]
 AS PARTITION [UserRange]
 TO ([User01], [User02],[PRIMARY])

-- 删除一个点
ALTER PARTITION FUNCTION 
    [UserRange]()
   MERGE RANGE ('1100')

-- 增加一个点
ALTER PARTITION FUNCTION
    [UserRange]()
    SPLIT RANGE ('1200')
GO

-- 在最后增加一个文件组
ALTER PARTITION SCHEME [UserScheme124]
   NEXT USED [User03]
   GO

-- 查找一条记录在那个分区
select $partition.[UserRange](id),userid FROM usertable where userid = 1000120
SELECT *, $PARTITION.[Data Partition Range](ID) FROM MyTable
