sql复制表结构和数据的实现方法

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 

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

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

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

select [col1,col2,col3...] into new_table 
from old_table where 1=1 ;

insert into table1(col1,col2,col3,...) 
select [col1,col2,col3...] from table2 ;
