下面來說下，在SQL SERVER 2005的表分區裏，如何對已經存在的有數據的表進行分區，其實道理和之前在http://www.cnblogs.com/jackyrong/archive/2006/11/13/559354.html說到一樣，只不過交換下順序而已，下面依然用例子說明：
依然在c盤的data2目錄下建立4個文件夾，用來做4個文件組，然後建立數據庫
use master IF EXISTS (SELECT name FROM sys.databases WHERE name = N'Data Partition DB3') DROP DATABASE [Data Partition DB3] GO CREATE DATABASE [Data Partition DB3] ON PRIMARY (NAME='Data Partition DB Primary FG3', FILENAME= 'C:\Data2\Primary\Data Partition DB Primary FG3.mdf', SIZE=5, MAXSIZE=500, FILEGROWTH=1 ), FILEGROUP [Data Partition DB3 FG1] (NAME = 'Data Partition DB3 FG1', FILENAME = 'C:\Data2\FG1\Data Partition DB3 FG1.ndf', SIZE = 5MB, MAXSIZE=500, FILEGROWTH=1 ), FILEGROUP [Data Partition DB3 FG2] (NAME = 'Data Partition DB3 FG2', FILENAME = 'C:\Data2\FG2\Data Partition DB3 FG2.ndf', SIZE = 5MB, MAXSIZE=500, FILEGROWTH=1 ), FILEGROUP [Data Partition DB3 FG3] (NAME = 'Data Partition DB3 FG3', FILENAME = 'C:\Data2\FG3\Data Partition DB3 FG3.ndf', SIZE = 5MB, MAXSIZE=500, FILEGROWTH=1 ), FILEGROUP [Data Partition DB3 FG4] (NAME = 'Data Partition DB3 FG4', FILENAME = 'C:\Data2\FG4\Data Partition DB3 FG4.ndf', SIZE = 5MB, MAXSIZE=500, FILEGROWTH=1 ) 然後建立一個數據表：
USE [Data Partition DB3] go CREATE TABLE MyTable (ID INT NOT NULL, Date DATETIME, Cost money ) on [primary] 並建立一個索引
USE [Data Partition DB3] go CREATE UNIQUE CLUSTERED INDEX MyTable_IXC ON MyTable(ID) on [PRIMARY] 接下來往表裏增加數據
USE [Data Partition DB3] go declare @count int set @count =-25 while @count <=100 begin insert into MyTable select @count,getdate(),100.00 set @count=@count+1 end set @count =101 while @count <=200 begin insert into MyTable select @count,getdate(),200.00 set @count=@count+1 end set @count =201 while @count <=300 begin insert into MyTable select @count,getdate(),300.00 set @count=@count+1 end set @count =301 while @count <=400 begin insert into MyTable select @count,getdate(),400.00 set @count=@count+1 end set @count =401 while @count <=800 begin insert into MyTable select @count,getdate(),500.00 set @count=@count+1 end 此時查詢一下，可以看到數據都在一個表裏 select * from sys.partitions where object_name(object_id)='MyTable'
我們再建立表分區函數 use [Data Partition DB3] GO CREATE PARTITION FUNCTION [Data Partition Range](int) AS RANGE LEFT FOR VALUES (100,200,300) 這裏表明分區的原則是四個分區，從負數到100，101-200，201-300，大於300
當然，如果用right for values的話，就是從負數到99，100到199，200-299，和大於300
最後，把表分區函數應用到文件組裏
USE [Data Partition DB3] go CREATE PARTITION SCHEME [Data Partition Scheme] AS PARTITION [Data Partition Range] TO ([Data Partition DB3 FG1], [Data Partition DB3 FG2], [Data Partition DB3 FG3],[Data Partition DB3 FG4]); 把原來建立好的表，移動到這個表分區裏
Drop index MyTable_IXC on MyTable with (Move To [Data Partition Scheme] (ID) )
最後看一看 select * from sys.partitions where object_name(object_id)='MyTable'
可以看到，原來的表的數據被正確分拆到四個文件組裏去了，實現了表分區
