joining queries on multiple servers

In Sql server we can create Linked servers to execute/join queries on multiple servers/databases.
we can creae linked server by using Management studio option or by using the script like
EXEC master.dbo.sp_addlinkedserver @server = N'RemoteServerName', @srvproduct=N'DB', @provider=N'SQLNCLI', @datasrc=N'RemoteServerName', @provstr=N'Data Source=RemoteServerName;Initial Catalog=DB_NAME;Persist Security Info=True;User ID=sa;Password=password', @catalog=N'MY_DB' /* For security reasons the linked server remote logins password is changed with ######## */EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'RemoteServerName',@useself=N'False',@locallogin=NULL,@rmtuser=N'sa',@rmtpassword='########'
GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'collation compatible', @optvalue=N'false'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'data access', @optvalue=N'true'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'dist', @optvalue=N'false'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'pub', @optvalue=N'false'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'rpc', @optvalue=N'false'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'rpc out', @optvalue=N'false'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'sub', @optvalue=N'false'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'connect timeout', @optvalue=N'0'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'collation name', @optvalue=nullGOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'lazy schema validation', @optvalue=N'false'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'query timeout', @optvalue=N'0'GOEXEC master.dbo.sp_serveroption @server=N'RemoteServerName', @optname=N'use remote collation', @optvalue=N'true'
When we are finished with the creation of Linked Server
we can write any query like
Insert Into RemoteServerName.MY_DB.dbo.MY_TABLE
select columns from current server database table.
