> Modeler DbImport: Can't retrieve schema for databases with no catalog support
> -----------------------------------------------------------------------------

> I am trying to db-import model for Hana DB. DB Import itself ("Run Import"
> button) works, if I manually add all the settings. However "Refresh DB
> Schema" button results in an empty schema.
> The cause of it seems to be the implementation of DatabaseSchemaLoader.load
> method. It looks for catalogs, and if none found, returns an empty result.
> Hana does not support catalogs, but supports schemas. And we need to support
> this case.
> I guess in general we need to support all combinations of schema and catalog
> presence across different databases:
> 1. Schema and Catalog (?)
> 2. Catalog only (MySQL)
> 3. Schema only (Hana ... who else?)
> 4. No schema or catalog (any DBs like this?)
