But it often can be used to limit the amount of data that has to be transferred over the network, or to prevent the query optimizer from choosing bad plans. Danut Multakh Supporter.
Are Linked Servers bad? Are Linked Servers Bad? Linked servers are a simple way to make remote data sources appear to SQL Server as a native table from a query perspective.
Therefore, all activities on the linked table are performed using a table scan. If the remote table is large, this can be horrible when it comes to performance. Marizol Thal Beginner. How do you query a linked server? Querying a Linked Server.

You can use Access as a front-end application and then link to tables in a back-end server, such as SQL Server. By default, most queries run locally in the Access ACE database engine.
Often though, you want to explicitly run a query on a database server. You do this to help improve performance: database servers have greater processing power than a desktop computer and you can return a smaller subset of data over the network connection. Note The results of a pass-through query are read-only. To directly edit data in a datasheet or form, create a linked table to an indexed view.
For more information, see Create Indexed Views. In the navigation pane, right click a table linked to the desired data source, and select Linked Table Manager. In the Linked Table Manager dialog box, select the check box of the data source, and then select Edit. In the Edit Link dialog box, copy the text in the Connection string box. Select Build. Follow the prompts to create a DSN file that contains the connection string information.
This ensures the query has correct syntax. If the query returns records, set this property to Yes ; if the query doesn't return records, set this property to No. Note Pass-through queries can return multiple result sets, but in a datasheet, form, report, or recordset variable, only the first result set is used. To retrieve multiple result sets, use a make table query as the following example shows:. Each result set is saved in a separate table and numbers are appended to the local table names accordingly.
The table name has the format, username — nn, where username is the sign in name for the current user, and nn is a number starting at ODBC Timeout Specify the number of seconds to wait before a time-out error occurs when a query is run.
The default value is 60 seconds. There may be delays due to network traffic or heavy use of the database server.
Max Records Specify the maximum number of records to return. You may have limited system resources or you want to test your results with just a small amount of data. Your query is sent to the database server for processing. Transact-SQL Reference. Querying with Transact-SQL.
