exec sp_addlinkedserver ' itsv ', ' ', ' SQLOLEDB ', ' Remote server name or IP address '
exec sp_addlinkedsrvlogin ' itsv ', ' false ', NULL, ' username ', ' password '

--query Example
SELECT * from ITSV. Database name. dbo. Table name

--import Example
SELECT * into table from ITSV. Database name. dbo. Table name

--Remove linked server when no longer in use
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)

--Raw cost surface
SELECT * Into table from OPENROWSET (' SQLOLEDB ', ' SQL Server name '; ' User name '; ' Password ', database name. dbo. Table name)

--Import local tables to remote tables
Insert OPENROWSET (' SQLOLEDB ', ' SQL Server name '; ' User name '; ' Password ', database name. dbo. Table name)
Select *from Local surface

--Update the local surface
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
