To obtain only the database URI of the datasource, I would perform the below steps in the Virtual DataPort Administration Tool:
* **[Create a JDBC datasource](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources#jdbc-sources)** by selecting the appropriate Denodo Virtual DataPort adapter as the Database adapter and provide necessary details.
* Then, create a base view using the **[create from query](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources#creating-base-views-from-sql-queries)** option and use the **[DESC](https://community.denodo.com/docs/html/browse/8.0/en/vdp/developer/appendix/output_schema_of_the_desc_commands/output_schema_of_the_desc_commands#output-schema-of-the-desc-commands)** command with **[interpolation variables](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_data_sources_and_base_views/path_types_in_virtual_dataport/path_types_in_virtual_dataport#paths-and-other-values-with-interpolation-variables)** like
‘**Desc datasource @datasource_type @datasource_name**’
* Navigate to **Options** -> **Search methods** of the created base view and in the **wrapper source configuration** section, I would set the ‘**Delegate SQL sentence as subquery**’ as ‘**NO**’ in order to send the query to the datasource directly instead of sending as a subquery.
* Then, **[create a selection view](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_derived_views/creating_selection_views/creating_selection_views#creating-selection-views)** upon this base view to get only the Connection URI as the output field.
Now, when I execute this selection view by providing the database name and data source name, I was able to get the Database URI information for the inputs specified.
You can take a look at a similar community **[data source connection string information](https://community.denodo.com/answers/question/details?questionId=9060g0000004ElSAAU&title=data+source+connection+string+information)** for more information.
Hope this helps!
