On successful connection, select the *Link Objects* button to obtain a list of available tables. %BR%%BR%<img src="%ATTACHURLPATH%/VirtLinkPGR2.png" style="wikiautogen"/>%BR%%BR% 6. Select all the tables that you would like to link. %BR%%BR%<img src="%ATTACHURLPATH%/VirtLinkPGR3.png" style="wikiautogen"/>%BR%%BR% 7. Change the Catalog for each table to be *PGR* using the *Set All* button. %BR%%BR%<img src="%ATTACHURLPATH%/VirtLinkPGR4.png" style="wikiautogen"/>%BR%%BR% 8. All the catalog names are changed to *PGR*. %BR%%BR%<img src="%ATTACHURLPATH%/VirtLinkPGR5.png" style="wikiautogen"/>%BR%%BR% 9.

The linked tables can be queried by clicking on the hyperlink in the *Local Name* column of the *External Linked Objects* tab above. This loads the Virtuoso *Interactive SQL* interface with the required SQL *Select* for retrieving the remote table data. We shall use the *PGR.PGR.Customers* table to demonstrate this. %BR%%BR%<img src="%ATTACHURLPATH%/VirtLinkPGR9.png" style="wikiautogen"/>%BR%%BR% 12. Click the *Execute* button to run the query and retrieve results from the remote table. %BR%%BR%<img src="%ATTACHURLPATH%/VirtLinkPGR10.png" style="wikiautogen"/>%BR%%BR% 13. The tables can also be viewed as part of the Virtuoso *SQL Schema Objects* under the *PGR* catalog name. %BR%%BR%<img src="%ATTACHURLPATH%/VirtLinkPGR8.png" style="wikiautogen"/>%BR%%BR% The Link process is now complete enabling the tables to be queried as if part of the Virtuoso Schema. ---++ Related * [[VOSSQL2RDF][Mapping SQL Data to Linked Data Views]] * [[VirtPostgresEntityFrameworkUsage][Using Microsoft Entity Frameworks to Access PostgreSQL Schema Objects (Tables, Views, and Stored Procedures) with Virtuoso]] CategoryDocumentation CategoryVirtuoso CategoryDotNET CategoryEntityFrameworks CategoryWebSite
