What are some good Modern Books on PL SQL?

Question

Oracle

Actually, subject. I would like some book that could serve as a good base. In order to read, relatively speaking, from cover to cover, to find out most of what is usually required, to acquire a good comprehensive idea of ​​​​what's what, and then point-to-point googling what is missing.
There are some books at https://docs.oracle.com/pls/db102/portal.portal_db...
There are also different Urmans and others, but they all have one thing in common - they are ancient. From 2004, something a little newer.
Therefore, an additional question for practicing pl'ists: how much has everything changed to version 18? Wouldn't it be like playing DotA in 2020 according to guides from 2015?

Answer 1

It seems that there is fresh information in the official oracle doc , it is well structured and even written in human language, not clerical. Exactly what is needed.

Answer 2

Book by Feuerstein S., Pribyl B. - Oracle PLS.QL. For professionals - a really good book, it helped me easily to cope with the concept of PL SQL
