Method of copying table data between different databases in SQL Server

The method of copying table data between different databases:

When the table target table exists:

insert into destination database..table select * from source database..table

When the target table does not exist:

select * into destination database..table from source database..table

--If between different SQL:

insert into openrowset('sqloledb','destination server name';'sa';'',destination database.dbo.table)
select * from source database..table

-- create link server exec sp_addlinkedserver    ' ITSV ' , ' ' , ' SQLOLEDB ' , ' remote server name or ip address ' exec sp_addlinkedsrvlogin ' ITSV ' , ' false ' , null , ' username ' , ' password '--Query example select * from



   ITSV.DatabaseName.dbo.TableName

-- Import example select * into table from ITSV.DatabaseName.dbo.TableName -- Remove the linked server when it is no longer used in the future exec sp_dropserver ' ITSV ' , ' droplogins ' -- connect remote /LAN data (openrowset/openquery/opendatasource) -- 1, openrowset -- query example select * from openrowset ( ' SQLOLEDB ' , ' sql server name ' ; ' user name ' ; ' password '




        , database name. dbo. table name)

-- generate local table select * into table from openrowset ( ' SQLOLEDB ' , ' sql server name ' ; ' user name ' ; ' password ' , database name. dbo. table name) -- Import the local table into the remote table insert openrowset ( ' SQLOLEDB ' , ' sql server name ' ; ' user name ' ; ' password ' , database name.dbo. 表名) select*from



   Local table

-- update local table update b set b. Column A = a. Column A from openrowset ( ' SQLOLEDB ' , ' sql server name ' ; ' user name ' ; ' password ' , database name.dbo.table name) as a inner join local table b on a.column1 = b.column1 -- openquery usage needs to create a connection -- first create a connection to create a linked server exec sp_addlinkedserver    ' ITSV ' , '



  ' , ' SQLOLEDB ' , ' remote server name or ip address '
-- query select * FROM openquery (ITSV, ' SELECT * FROM database.dbo. table name ' ) -- import the local table into the remote table insert openquery (ITSV, ' SELECT * FROM database.dbo.table name ' ) select * from local table -- update local table update b set b.column B = a.column B FROM openquery (ITSV, ' SELECT * FROM database.dbo.table name






  ' ) as a
inner join local table b on a. Column A = b. Column A

-- 3. opendatasource/openrowset SELECT * FROM opendatasource ( ' SQLOLEDB ' , ' Data Source=ip/ServerName;User ID=login name;Password =password ' ).test.dbo.roy_ta -- import the local table into the remote table insert opendatasource ( ' SQLOLEDB ' , ' Data Source=ip/ServerName;User ID=login name;Password=password ' ).Database.dbo.table nameselect * from _

好吧，如果上面看得烦下面有个更容易理解的例子：

Exec sp_droplinkedsrvlogin DBVIP,Null
Exec sp_dropserver DBVIP

EXEC sp_addlinkedserver
      @server='DBVIP',--被访问的服务器别名
      @srvproduct='',
      @provider='SQLOLEDB',
      @datasrc='Server2'   --要访问的服务器

EXEC sp_addlinkedsrvlogin
     'DBVIP', --被访问的服务器别名
     'false',
     NULL,
     'sa', --帐号
     'thankyoubobby' --密码

Select * from DBVIP.pubs.dbo.orders

/////////////////////////////ORACLE////////////////////////////
Exec sp_droplinkedsrvlogin demo,Null
Exec sp_dropserver demo
go

EXEC sp_addlinkedserver
        @server ='demo',
        @srvproduct='Oracle',
   @provider='MSDAORA',
   @datasrc='ServiceName'

EXEC sp_addlinkedsrvlogin
     'demo',
     'false',
     NULL,
     'userid',
     'password'
go

SELECT * FROM OPENQUERY(demo ,'select * from tbdemo' )

UPDATE OPENQUERY (demo, 'SELECT id FROM tbdemo WHERE id = 101')
SET name = 'hello';

INSERT OPENQUERY (demo, 'SELECT id FROM tbdemo')
VALUES ('hello');

DELETE OPENQUERY (demo, 'SELECT id FROM tbdemo WHERE name = ''hello''');

-------------------------------------------具体例子------------------------------------------------------------

if   exists(select   1   from   master.dbo.sysservers   where   srvname   =   'test')
begin
exec   sp_droplinkedsrvlogin     'test','sa'
exec   sp_dropserver     'test'
end

--建立连接服务器
EXEC sp_addlinkedserver 'test', 'ms','SQLOLEDB', '192.168.1.99'

exec sp_addlinkedsrvlogin 'test','false',null,'sa',''
select * from test.db_film.dbo.T_film
go

if   exists(select   1   from   master.dbo.sysservers   where   srvname   =   'test')
begin
exec   sp_droplinkedsrvlogin     'test','sa'
exec   sp_dropserver     'test'
end

方法二：

1、新建一个连接服务器，连接到你要导入的服务器的IP地址(或者机器名)

2、点击安全性，使用此安全上下文建立连接，输入数据库服务器的用户名和密码

3、选择要导出的数据库，使用如下sql导数据：

select * into laobao from [10.180.116.121].ynpdeicp.dbo.LaoBao

Sql解释：

select 要导入的字段 into 要导入的数据表 from [IP地址].数据库名.dbo.数据表名
