Migration from MySQL to Oracle generates empty tables I'm using SQL Developer to migrate a database from MySQL 5.7 to Oracle 18c XE. The problem is that the tables are generated but empty, even though I'm specifying that the data should move online. I also looked at the scripts, and there's no data either.

Solution: create a user/schema in Oracle that has the same name as the database you want to import.
