Partition--分区切换

现有数据表[dbo].[staging_TB1_20131018-104722]和分区表[dbo].[TB1],需要将分区表和数据表中做数据交换
CREATE TABLE [dbo].[staging_TB1_20131018-104722](
 [C1] [int] NOT NULL,
 [C2] [nvarchar](200) NULL,
 [C3] [nvarchar](200) NULL,
 [PID] [bigint] NOT NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[staging_TB1_20131018-104722]  WITH CHECK ADD  CONSTRAINT [chk_staging_TB1_20131018-104722_partition_496] CHECK  (([PID]>N'495000' AND [PID]<=N'496000'))
GO
ALTER TABLE [dbo].[staging_TB1_20131018-104722] CHECK CONSTRAINT [chk_staging_TB1_20131018-104722_partition_496]
GO
CREATE TABLE [dbo].[TB1](
 [C1] [int] IDENTITY(1,1) NOT NULL,
 [C2] [nvarchar](200) NULL,
 [C3] [nvarchar](200) NULL,
 [PID] [bigint] NOT NULL
)
GO
CREATE UNIQUE CLUSTERED INDEX [CI_PID_CI] ON [dbo].[TB1] 
(
 [C1] ASC,
 [PID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, 
SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, 
ONLINE = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON)
ON pf_Test([C1])
GO
------------------------------------------------------------------------------------------------------------------------------------------------------
查找分区表的对应的分区ID
SELECT $PARTITION.pf_Test(496000)
 
将数据表数据导入到分区表中
ALTER TABLE [dbo].[staging_TB1_20131018-104722]
SWITCH TO [dbo].[TB1] PARTITION 496
 
将分区表中数据导入到数据表
ALTER TABLE [dbo].[TB1]
SWITCH PARTITION 496 TO [dbo].[staging_TB1_20131018-104722]
