SQL Developer Data Modeler

Hello,

I'm new to using oracle developer data modeler and oracle apex and I have very little knowledge of DB, so I apologize if I make big mistakes.

context: I recently started a course in DB management and I have to realize for a lab an application on apex allowing to access several tables and to add / modify / search data.

So I made a logical model on data modeler then I regenerate the physical model.

here is what i get

I then generated the sql script by exporting a ddl file with all my tables, here is what I get

once this done, i was on apex> utilities> quick sql and pasted my sql script

however, once the sql is generated and saved, when I try to review and run the script the following error appears:

I searched the net and I did not find an answer correcting my error (maybe I was looking badly)

if anyone would know how to fix this error it would help me a lot
