A paper copy of the manual can be most useful, since I, like most people, find it hard to wade through an online manual.
But there is one area in which the online form is more useful: searching. By opening the MySQL manual in a text editor, one can search it, making the poor organization of the manual less of a problem.
The printed copy suffers from the same poor organization (indeed, it is the same as - or very, very close to - the online manual) but without the ameliorating factor of searchability. The index is not very good, but even if it was better, the scattering of information throughout the book would make for lengthy index entries.
Take security for example. What is the recommended process for securing a fresh MySQL installation? Start at the Table of Contents: Aha! 4.3 "MySQL User Account Management" Sounds promising. P. 249. GRANT and REVOKE Syntax? Not what I had in mind. I just want to know about the right way to secure the system and create new users. Back to the Contents. 2.4 "Post-Installation Setup and Testing" P.113. Nope, nothing there.
Last resort: The index. Security, against hackers, p.227. Nope. But that page is in section 4.2 "General Security Issues and the MySQL Access Privilege System." Now that sounds like it. Start reading section 4.2.1 on p. 224... "If you are able to connect successfully to the server without being asked for a password, you have problems! ... Review the MySQL installation instructions..." I thought I just did that. Now I know the secret is burried in the installation instructions. Back to Chapter 2. Still no dice.
Give up and install phpMyAdmin.
While I don't doubt that the answers to this and a myriad other questions are in there somewhere, the poor structure of the book makes it extremely hard to find anything.
A complete rewrite would do the trick.
