前言:线上一数据表数据量很大，导致扫描缓慢，新增一数据表转移，转移表中有自增列....
USE [master]
GO
--新增一数据库历史区域
CREATE DATABASE [Sfis_History] ON PRIMARY
( NAME = N‘Sfis_History‘, FILENAME = N‘D:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Sfis_History.mdf‘ , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
LOG ON
( NAME = N‘sfis_History_log‘, FILENAME = N‘D:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\sfis_History_1.ldf‘ , SIZE = 1024KB , FILEGROWTH = 10% )

-- 1) 直接插入的方法
SELECT * INTO Sfis_History.dbo.T_matstate FROM Sfis.dbo.T_matstate WHERE scandate < ‘2013-01-01‘
SELECT * INTO Sfis_History.dbo.T_matstatereplace FROM Sfis.dbo.T_matstatereplace WHERE scandate < ‘2013-01-01‘
-- 2)先新增表结果，再转移数据
SELECT * INTO Sfis_History.dbo.T_matstate FROM Sfis.dbo.T_matstate WHERE 1 <> 1
SELECT * INTO Sfis_History.dbo.T_matstatereplace FROM Sfis.dbo.T_matstate WHERE 1 <> 1
