sql复制表结构和数据的实现方法-木庄网络博客

SQL SERVER中使用SELECT … INTO语句

按照使用场合可以分为以下几类：

1．实现全表备份：如：SELECT * INOT t1 FROM titles

2．备份表的一部分列（不写*而写出列的列表）或一部分行（加WHERE条件）

如：

SELECT title_id,title,price INTO t2 FROM titles—部分列 
SELECT * INTO t2 FROM titles WHREE price>10 –部分行 
SELECT title_id,title,price INTO t2 FROM titles WHREE price>10 –部分行和部分列

3．只复制表的结构：

SELECT * INTO tablename_new FROM tablename_old

如：SELECT * INOT t1 FROM titles WHERE 1=2

4．查询结果来源于多个表：如：

SELECT title_id,title,pub_name INTO t3 
FROM titles t INNER JOIN publishers p 
ON t.pub_id=p.pub_id

5.select * into 要复制到的数据库名.DBO.表名 from 原数据库名.DBO.表名

从news表复制指定字段到news1

set IDENTITY_INSERT [dbo].[news1] ON
INSERT INTO [dbo].[news1] ([id],[title],[stitle],[type_id],[scontent],[keyword],[tag],[author]) SELECT [id],[title],[stitle],[type_id],[scontent],[keyword],[tag],[author] 

FROM [dbo].[news]
set IDENTITY_INSERT [dbo].[news1] OFF

2.从news表复制id,content字段到content_1(id指定区间)

create table content_1([id] [int] primary key NOT NULL, [content] [text] NULL)
INSERT INTO [dbo].[content_1] ([id],[content] ) SELECT [id],[content] FROM [dbo].[news] where [id] between 1 and 100000
create table content_2([id] [int] primary key NOT NULL, [content] [text] NULL)
INSERT INTO [dbo].[content_2] ([id],[content] ) SELECT [id],[content] FROM [dbo].[news] where [id] between 100001 and 200000
create table content_3([id] [int] primary key NOT NULL, [content] [text] NULL)
INSERT INTO [dbo].[content_3] ([id],[content] ) SELECT [id],[content] FROM [dbo].[news] where [id] > 200000
