Hi, I tried adding the database name in the Generate entities dialog box, and also modified the connection string to TESTUSER@localhost:1521:XE But, as you can see, there is not exactly a db name, but a user that can access some tables in a table space. So, I'm not really sure what should I set on the database field: the tablespace, the user, or, modifying the connection string.
