This page contains all versions of my book The Power of Oracle SQL (rus).

Published title Oracle SQL Revealed (eng).

Russian

English

Some changes in compare to Russian version:

Part I

  • First chapter was thoroughly refactored in order to make it easier to read. It has a huge number of examples and they have been structured a bit better.
  • New chapter “Aggregate Functions” (it also includes information about pivoting/unpivoting).
  • Some details about performance and internal implementation were added regarding pattern matching.
  • Chapter “Logical Execution Order of Query Clauses” was completely reworked. In Russian version it contains a few inaccuracies which may lead to wrong conclusions.

Part II

  • Solutions for a few of quizzes have been improved or changed. In particular, for Ordering Dependencies and Resemblance Group.
  • Some new approaches have been introduced, for instance, for Zeckendorf Representation, etc.
