下面來說下，在SQL SERVER 2005的表分區里，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，然后建立數據庫

use masterIF; EXISTS (SELECT name FROM sys.databases WHERE name = N'Data Partition DB3')DROP DATABASE [Data Partition DB3]GOCREATE DATABASE [Data Partition DB3]ON PRIMARY(NAME='Data Partition DB Primary FG3',FILENAME='C:Data2PrimaryData Partition DB Primary FG3.mdf',SIZE=5,MAXSIZE=500,FILEGROWTH=1 ),FILEGROUP [Data Partition DB3 FG1](NAME = 'Data Partition DB3 FG1',FILENAME ='C:Data2FG1Data Partition DB3 FG1.ndf',SIZE = 5MB,MAXSIZE=500,FILEGROWTH=1 ),FILEGROUP [Data Partition DB3 FG2](NAME = 'Data Partition DB3 FG2',FILENAME ='C:Data2FG2Data Partition DB3 FG2.ndf',SIZE = 5MB,MAXSIZE=500,FILEGROWTH=1 ),FILEGROUP [Data Partition DB3 FG3](NAME = 'Data Partition DB3 FG3',FILENAME ='C:Data2FG3Data Partition DB3 FG3.ndf',SIZE = 5MB,MAXSIZE=500,FILEGROWTH=1 ),FILEGROUP [Data Partition DB3 FG4](NAME = 'Data Partition DB3 FG4',FILENAME ='C:Data2FG4Data Partition DB3 FG4.ndf',SIZE = 5MB,MAXSIZE=500,FILEGROWTH=1 )然后建立一個數據表：USE [Data Partition DB3]goCREATE TABLE MyTable(ID INT NOT NULL,Date DATETIME,Cost money ) on [primary]并建立一個索引USE [Data Partition DB3]goCREATE UNIQUE CLUSTERED INDEX MyTable_IXCON MyTable(ID) on [PRIMARY]接下來往表里增加數據USE [Data Partition DB3]godeclare @count intset @count =-25while @count <=100begininsert into MyTable select @count,getdate(),100.00set @count=@count+1endset @count =101while @count <=200begininsert into MyTable select @count,getdate(),200.00set @count=@count+1endset @count =201while @count <=300begininsert into MyTable select @count,getdate(),300.00set @count=@count+1endset @count =301while @count <=400begininsert into MyTable select @count,getdate(),400.00set @count=@count+1endset @count =401while @count <=800begininsert into MyTable select @count,getdate(),500.00set @count=@count+1end此時查詢一下，可以看到數據都在一個表里select * from sys.partitions where object_name(object_id)='MyTable'我們再建立表分區函數use [Data Partition DB3]GOCREATE PARTITION FUNCTION [Data Partition Range](int)AS RANGE LEFT FOR VALUES (100,200,300)這里表明分區的原則是四個分區，從負數到100，101-200，201-300，大于300當然，如果用right for values的話，就是從負數到99，100到199，200-299，和大于300最后，把表分區函數應用到文件組里USE [Data Partition DB3]goCREATE 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，移動到這個表分區里Drop index MyTable_IXC on MyTable with (Move To [Data Partition Scheme] (ID) )最后看一看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里去了，實現了表分區
