Hello, I am learning very basic data modelling in SQL Developer, at this stage I don't want to install the stand alone Oracle Data Modeler app.
So I created a foreign key constraint that linked the Branches table to the countries table using COUNTRYID column like this
When on click on the “copy to Data Modeler” button
Why there is no relationship line shown between the two tables like it does in the table's model tab?
Thank you.
