I am just following the instructions in the Tutorial.
And are we supposed to guess what 'Tutorial' you are talking about?
Is there is a conflict between versions?
Between versions of what?
I need help to move ahead.
If you need help you need to
1. post in the correct forum
2. provide detailed information about WHAT you are doing, what TOOL (sql developer, sql*plus, Oracle, etc) you are doing it with
3. provide info about the results you are getting
4. provide info about the results you expected to get
At the forum title says this forum is for SQL Developer questions and NOT for SQL or PL/SQL questions.
Nothing in what you posted indicates your question is about sql developer.
Mark this thread ANSWERED and repost it in the SQL and PL/SQL forum
Based ONLY on what you posted you are trying to insert CHILD records into a table that has a FOREIGN KEY to a PARENT table and the parent records are missing.
You have to insert parent records before you can insert the child records.
Apologies for the stupid way of posting. Please see the correct post in the advised thread
