This book for interview questions in Oracle only Sql which we face every now and then. I making it very clear that It doesn’t contain PL part. Sql itself is big and interesting subject in itself It gives point to point answer to relevant question. It doesn’t explain in detail anything because it is interview preparation. I have tried my best that information are accurate in book. And as you now in software industry, there is always better way to do things. If anything you want understand the best resource is Google, Bing and there are many books and training course available out there in market.
