Remote access via SQL

Tag: style ar color using SP for data on log

accessing remote databases with SQL statements

1, to establish a linked server:
--Delete linked server
if exists (SELECT * from Master.dbo.sysservers where isremote=0 and Srvname= ' ITSV ')
exec sp_dropserver ' itsv ', ' droplogins '

--Create a connection server
exec sp_addlinkedserver ' itsv ', ', ' SQLOLEDB ', ' 10.2.10.211 '
exec sp_addlinkedsrvlogin ' itsv ', ' false ', NULL, ' Retailbi ', ' retail '
2, after the establishment of the linked server, you can use it to arbitrarily manipulate the remote database.
--query Example
SELECT * from ITSV. Database name. dbo. Table name
--pk
SELECT * from sys.key_constraints where object_id = object_id (' TB ')
--fk
SELECT * from Sys.foreign_keys where parent_object_id =object_id (' TB ')
--Create a linked 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. 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
--openquery usage requires creating 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 local tables to remote tables
Insert OpenQuery (ITSV, ' SELECT * from database. dbo. Table name ')
SELECT * FROM local surface
--Update the local surface
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
Set SQL Server timed execution commands

1. Open Object Explorer and locate SQL Server Agent

2. New Job

3. Fill in the Job name and description information in the general item, job properties

Commands of type Transact-SQL script (T-SQL) in the step item, job properties, such as exec sp_procedure (if you have more than one step, be sure to go to the next step if you have successful previous steps)

Schedule items, set timing for command execution, and so on in job properties

4, determine.

5. Start the SQL Server Agent
