背景：对NEWISS数据库创建分区表T_SALES的SQL。按照日期来进行分区

步骤：
1：创建文件组
2：创建数据文件
3：创建分区函数
4：创建分区方案
5：创建表及聚集索引
6：导入测试数据（此处略），并查询数据分区情况
7：测试交换分区
8：测试合并分区
9：测试拆分分区

--创建7个文件组

ALTER DATABASE [NEWISS]
ADD FILEGROUP [FG_SALES_SYSDATE_6]

ALTER DATABASE [NEWISS]
ADD FILEGROUP [FG_SALES_SYSDATE_7]

--创建7个数据文件

--创建分区函数,边界值使用右分区
CREATE PARTITION FUNCTION
FUN_SALES_SYSDATE(DATE) AS
RANGE RIGHT
FOR VALUES('2013-02-01','2013-03-01','2013-04-01','2013-05-01','2013-06-01','2013-07-01')

--创建分区方案
CREATE PARTITION SCHEME
SCH_SALES_SYSDATE AS
PARTITION FUN_SALES_SYSDATE
TO([FG_SALES_SYSDATE_1],[FG_SALES_SYSDATE_2],[FG_SALES_SYSDATE_3],[FG_SALES_SYSDATE_4],[FG_SALES_SYSDATE_5],[FG_SALES_SYSDATE_6],[FG_SALES_SYSDATE_7])

--交换分区
ALTER TABLE [dbo].[T_SALES] SWITCH PARTITION 1 TO [dbo].[T_SALES_201301] PARTITION 1

--合并分区（将2013年2月与3月的数据合并）
ALTER PARTITION FUNCTION FUN_SALES_SYSDATE() MERGE RANGE ('2013-03-01')

--拆分分区（将2013年8月1日以后的数据放到新分区）
--1：先指定分区方案下一个分区使用哪个文件组（如果需使用新文件组则需要再创建一个文件组，本例中使用刚交换出去的文件组FG_SALES_SYSDATE_1）
ALTER PARTITION SCHEME SCH_SALES_SYSDATE NEXT USED FG_SALES_SYSDATE_1
--2：拆分（指定拆分分界点2013-08-01）
ALTER PARTITION FUNCTION FUN_SALES_SYSDATE() SPLIT RANGE ('2013-08-01')

--使用存储过程适当进行sql拼接进行拆分分区/交换分区存档数据的操作，建立job定期执行做到分区定期自动维护。
