Hi, I recently connected MS SQL Community 2019 with a local Oracle 19c database using Polybase. Polybase seems really insistent on using "Create External Table" to get access to the external database. So do I have to Create External Table for every foreign table I want to read? That seems really tedious and you have to deal with column data type issues between ms sql and the foreign database. So is the architecture of Polybase to individually connect every table in the foreign database one at a time? Prior approaches like Linked Server let you make one connection to Oracle and you could then just use queries to refer to all the table resources in the other database.
