When I started to learn this book, I installed Oracle DB and started to use SQLPlus. I can not practice some exercise. For example, Chapter 1, page 26, We have to select isbn, author, title from books.
These data is their database (bob's) but not in my database. how can I insert that data?
I could not find abc.pkg from the zip files of the book.How can I install hr_schema_install.sql?
Please Help me
