You could use the stored procedure VIEW_DEPENDENCIES, to list the base view and its associated datasource.
I would execute the below query in a VQL shell, to retrieve the list the views of type base view created from the Data source in a Database.
`Select dependency_name as DatasourceName, view_name as BaseViewName From VIEW_DEPENDENCIES ('<DatabaseName>',null) where view_type = 'Base View' and dependency_name = '<DatasourceName>'; `
You could refer the section [VIEW_DEPENDENCIES](https://community.denodo.com/docs/html/browse/6.0/vdp/vql/stored_procedures/predefined_stored_procedures/view_dependencies#view-dependencies) in Virtual DataPort VQL Guide for more details on it.
Hope this helps.
