I've been wrestling with this problem for a few weeks and since i'm trying to learn using the book "Beginning php5", it would be nice if someone involved (Auther) could help me fix this problem.
One of the problems i'm having is with the creating of the database script in the book.
The script is this one:-
<?php
include "./common_db.inc";
$dbname = "testsample_db";
$user_tablename = 'user';
$user_table_def = "usernumber MEDIUMINT(10) DEFAULT '0' NOT NULL AUTO_INCREMENT,";
$user_table_def .= "userid VARCHAR(8) BINARY NOT NULL,";
$user_table_def .= "userpassword VARCHAR(20) BINARY NOT NULL,";
$user_table_def .= "username VARCHAR(30) NOT NULL,";
$user_table_def .= "usercountry VARCHAR(50) NOT NULL,";
$user_table_def .= "useremail VARCHAR(50) NOT NULL,";
$user_table_def .= "userprofile TEXT NOT NULL,";
$user_table_def .= "registerdate DATE DEFAULT '0000-00-00' NOT NULL,";
$user_table_def .= "lastaccesstime TIMESTAMP(14),";
$user_table_def .= "PRIMARY KEY (userid),";
$user_table_def .= "UNIQUE usernumber (usernumber)";
$access_log_tablename = "access_log";
$access_log_table_def = "page VARCHAR(250) NOT NULL,";
$access_log_table_def .= "userid VARCHAR(8) BINARY NOT NULL,";
$access_log_table_def .= "visitcount MEDIUMINT(5) DEFAULT '0' NOT NULL,";
$access_log_table_def .= "accessdate TIMESTAMP(14),KEY page (page),";
$access_log_table_def .= "PRIMARY KEY (userid, page)";
$link_id = db_connect();
if(!$link_id) die(sql_error());
if(!mysql_query("CREATE DATABASE $dbname")) die(sql_error());
echo "Successfully created the $dbname database.<BR>";
if(!mysql_select_db($dbname)) die(sql_error());
if(!mysql_query("CREATE TABLE $user_tablename ($user_table_def);"))
die(sql_error());
if(!mysql_query("CREATE TABLE $access_log_tablename ($access_log_table_def)")) die(sql_error());
echo "Successfully created the $user_tablename and $access_log_tablename tables.";
The problem is with the line:-
$user_table_def = "usernumber MEDIUMINT(10) DEFAULT '0' NOT NULL AUTO_INCREMENT,";
Why does it not work....?????
I get an error message saying:-
Successfully created the testsample_db database.
1067: Invalid default value for 'usernumber'
Please can one of the Authers explain what the problem is or direct me to where i can find the answer.
Thank you.

You quoted the default of 0 (zero) on an integer field. Remove the quotes and try again. The database is trying to assign the varchar '0' to an integer field.
