In order to get the details of the particular data source, I would use the **DESC** statement which returns the description of the elements in the Virtual DataPort Server.For instance, if I want to get the JDBC datasource metadata, then the VQL will be,
DESC VQL DATASOURCE JDBC <datasource_name>
which returns the information about the data source like driver class name,connection uri etc.
For more information, you could refer to the section [Describing Catalog Elements](https://community.denodo.com/docs/html/browse/8.0/en/vdp/vql/describing_catalog_elements/describing_catalog_elements#describing-catalog-elements) from the Virtual DataPort VQL Guide.
Hope this helps!
