Matthew Morris (who makes many constructive and knowledgeable contributions to the forum) has written a series of study guides for the OCA/OCP exams. I asked him if I could have a copy of one to review. The result: it's very good. This is a copy of the review I put up on Amazon.
The other day, I was asked how to move a table from one schema to another. The answer, as we all know, is "you can't do that: you have to create a new table as a copy of the old one, or use export/import. It will take a long long time." Not true.

I've been asked by the publishers to review "Oracle Database 11g Release 2: Performance Tuning Tips and Techniques" by Richard Niemiec of TUSC. Conclusion: it is good but not perfect. This is an extended version of the review I put up on Amazon.

It gives me great pleasure and honour to announce my upcoming book Oracle Advanced PL/SQL Developer Professional Guide with Pact Publishers. The book 'Oracle Advanced PL/SQL Developer Professional Guide' is focussed on the preparation of OCP (1Z0-146) examination. The book doesn't restricts its scope to the examination but aims to strengthen the advanced concepts in Oracle 11g PL/SQL.
The book has been reviewed by Oracle ACEs Kamran Agayev, Ronald Rood and Mohan Dutta. It is under production and is expected to be released by May, 2012.
Basics of Partition Tables
Partitioning is a method of splitting an object (a table or index) into separate parts (called partitions) based on some criterion that is assigned to the partition. The criterion might be a date range, a number range, or any other possible value. Imagine, for example, that you have a huge table that is driving you crazy because queries on it are really slow. You get so mad at this table that you take a logical hatchet and begin to slice the table up into many smaller tables is a partition.
The old Oracle join syntax really should be consigned to history.
