In ArcGIS Desktop, you can use python or geoprocessing tools to create a database view via an SQL Query. After the view has been created, it's useful to be able to see the SQL query used to create it. In ArcCatalog, you could view this SQL by right clicking on the view, Properties, Definition tab. In ArcGIS Pro, there is no way to do this - once you've created the database view, you cannot go back in and see the SQL used.
Please provide some way of seeing the SQL used to create a database view in ArcGIS Pro.
