Start the Virtuoso Web User Interface.\n%BR%%BR%%BR%%BR%\n 2. Select the *Conductor* link in the left frame and login as the *dba* user.\n%BR%%BR%%BR%%BR%\n 3. Select the *Databases* -> *External Data Source* -> *Data Sources* tab menu items.\n%BR%%BR%%BR%%BR%\n 4. Select the *Connect* button for the *pg7ma* PostgreSQL DSN.\n%BR%%BR%%BR%%BR%\n 5. On successful connection, select the *Link Objects* button to obtain a list of available tables.\n%BR%%BR%%BR%%BR%\n 6. Select all the tables that you would like to link.\n%BR%%BR%%BR%%BR%\n 7. Change the Catalog for each table to be *PGR* using the *Set All* button.\n%BR%%BR%%BR%%BR%\n 8. All the catalog names are changed to *PGR*.\n%BR%%BR%%BR%%BR%\n 9. Select the *Link* button to link the selected tables into Virtuoso.\n%BR%%BR%%BR%%BR%\n 10. On completion of the Link process, the tables will be displayed in the *External Linked Objects* tab.\n%BR%%BR%%BR%%BR%\n 11. 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.\n%BR%%BR%%BR%%BR%\n 12. Click the *Execute* button to run the query and retrieve results from the remote table.\n%BR%%BR%%BR%%BR%\n 13. The tables can also be viewed as part of the Virtuoso *SQL Schema Objects* under the *PGR* catalog name.\n%BR%%BR%%BR%%BR%\n\nThe Link process is now complete enabling the tables to be queried as if part of the Virtuoso Schema.\n\n---++ Related\n\n * [[VOSSQL2RDF][Mapping SQL Data to Linked Data Views]]\n * [[VirtPostgresEntityFrameworkUsage][Using Microsoft Entity Frameworks to Access PostgreSQL Schema Objects (Tables, Views, and Stored Procedures) with Virtuoso]]\n\n\n CategoryDocumentation CategoryVirtuoso CategoryDotNET CategoryEntityFrameworks CategoryWebSite " .
