i will import my sql in PHPMyAdmin, the sql is below :

===============
#
# Table structure for table book
#

DROP TABLE IF EXISTS book;
CREATE TABLE book (
book_id int(5) DEFAULT '0' NOT NULL auto_increment,
title varchar(255) NOT NULL,

UNIQUE book_id (book_id, isdn)
);
# --------------------------------------------------------

#
# Table structure for table category
#

DROP TABLE IF EXISTS category;
CREATE TABLE category (

# Table structure for table loan
#

DROP TABLE IF EXISTS loan;
CREATE TABLE loan (
loan_no int(5) DEFAULT '0' NOT NULL auto_increment,
login varchar(200) NOT NULL,
bookid int(5) DEFAULT '0' NOT NULL,
date_out datetime DEFAULT '0000-00-00 00:00:00' NOT NULL,

);
# --------------------------------------------------------

#
# Table structure for table users
#

DROP TABLE IF EXISTS users;
CREATE TABLE users (

#
# Table structure for table wish
#

DROP TABLE IF EXISTS wish;
CREATE TABLE wish (
wishid int(5) DEFAULT '0' NOT NULL auto_increment,
name varchar(50) NOT NULL,
email varchar(30) NOT NULL,
subject varchar(150) NOT NULL,
date date DEFAULT '0000-00-00' NOT NULL,
flag varchar(10) NOT NULL,
PRIMARY KEY (wishid),
UNIQUE wishid (wishid)
);
================

the result is below :

Error

SQL query:

);

MySQL said: Documentation
#1067 - Invalid default value for 'book_id'
=============

how to solve this problem?

y'cant have a default value on an autoincrement column

..think about it for a moment
if you are instructing the db to assign an autoincrement value how or even why would you also supply a default value

not set default value for it

Oh re-he-heally?

george, i believe jsf008 is saying not to do that

(never mind that healdem already said that)

the original poster hasn't responded yet

Dear me, I assumed such a response was from the OP, not just a re-iteration of healdem's point.

Added value or what!
