    By using a linked server to retrieve data from several SQL instances, the only thing that should be done is to connect to one SQL instance. There are two ways of configuring linked server in SSMS. In this article will be explained how to configure a linked server using a SQL Server data source.

    More information about other data sources can be found on this link. The linked servers can be defined for different kind of data source if the Other data source radio button is chosen.

    If the SQL Server is a named instance, type the name of the computer and the name of the instance separated by slash e. Under the Local server login to remote server login mappings, two ways of local logging to a remote login can be set. One way is to associate a local login with a remote login and other way is to impersonate. Local Login In the Local Login field, will be listed all the local logins. The local login can be an SQL Server Authentication local login: Or a Windows Authentication login: Now, when clicking the OK button on the New Linked Server dialog, the following error message will appear: The login mappings should either be impersonate or have a remote login name.

    Impersonate The Impersonate check box when is checked passes the local login credentials to the linked server. For SQL Server Authentication, the same login with the exact credentials must exist on the linked server, otherwise when connected to the server with the SQL Server Authentication, the list of the databases under the Catalogs folder may look like this: For Windows logins, the login must be a valid login on the linked server. In order to use impersonation, the delegation between the local server and the linked server must be set.

    Basically, it allows local logins to connect to a remote server as a different login that must exist on a remote server. Remote Password Specify the password of the remote user. From the Local Login drop down list, choose a local login which should map to a remote login.

    On the Remote User field, enter the name of the remote user that exists on the remote server and in the Remote Password filed, enter a password of that remote user. For example, if login with different account e. Ben that not set in the login mapping list the list of the databases under the Catalogs folder will look like this: If you attempt to execute a linked server query: 1.

    Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle.

    Linked servers offer the following advantages: The ability to access data from outside of SQL Server. The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise.

    The ability to address diverse data sources similarly. Managing Linked Server Definitions When you are setting up a linked server, register the connection information and data source information with SQL Server.

    After being registered, that data source can be referred to with a single logical name. View information about the linked servers defined in a specific instance of SQL Server by running a query against the sys. You can also use this stored procedure to remove a remote server. You can delete a linked server definition by right-clicking the linked server name and selecting Delete.

    When you execute a distributed query against a linked server, include a fully qualified, four-part table name for each data source to query. Linked Server Details Linked servers are used to handle the distributed queries. The rowset request may be in the form of executing a query against the provider or opening a base table from the provider.

    When a third-party OLE DB provider is used, the account under which the SQL Server service runs must have read and execute permissions for the directory, and all subdirectories, in which the provider is installed.

    OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches. Although data sources queried through linked server definitions are ordinarily databases.

    How to Create a Linked Server Prerequisites You must be logged on with an account that is a member of the SQL Server sysadmin fixed server role to perform this procedure. This local login should exist before you begin this procedure.

    NOTE: This procedure often refers to the server you are linking to as the remote server. Do not confuse this usage with the obsolete remote server functionality in SQL Server. You will need to map a local server login to a remote server login. Check Impersonate if the local login also exists on the remote server. Alternatively, if the local login will be mapped to a remote SQL Server login you must supply the Remote User name and Remote Password for the remote server login.
