MySQLHow does a database create a user table and set its IDAuto-increment ColumnWhat about it? This article mainly introduces this process. First, we will introduce the testing environment, and then introduce the detailed Code created, hoping to help you.

Environment:

 
 

  
  
PhpMyAdmin SQL Dump
  
  
Version 3.3.8.1
  
  
Http://www.phpmyadmin.net
  
  
HOST: Export rdc.sae.sina.com.cn: 3307
  
  
Generation Date:, January 1, August 19, 2011
  
  
Server version: 5.1.47
  
  
PHP version: 5.2.9
  
  
Database: 'app _ tushow'
  
  
Table Structure 'users'
 
 

The created code is as follows:

 
 

  
  
Create table if not exists 'users '(
  
  
'Id' int (9) not null AUTO_INCREMENT,
  
  
'Name' varchar (32) not null,
  
  
'Full _ name' varchar (255) not null,
  
  
'Password' varchar (64) not null,
  
  
'Login _ count' int (10) unsigned not null default '0 ',
  
  
'Last _ login' int (10) unsigned not null default '0 ',
  
  
'Email 'varchar (64) default null,
  
  
'Admin' tinyint (1) DEFAULT '0 ',
  
  
'Users' tinyint (1) DEFAULT '0 ',
  
  
'Hash' char (32) default null,
  
  
'Url' varchar (255) default null,
  
  
'Locale' char (10) default null,
  
  
Primary key ('id '),
  
  
Unique key 'name' ('name '),
  
  
Unique key 'hash' ('hash ')
  
  
) ENGINE = MyISAM default charset = utf8 AUTO_INCREMENT = 3;
  
  
Store data in tables 'users'
  
  
Insert into 'users' ('id', 'name', 'full _ name', 'Password', 'login _ count', 'last _ login', 'email ', 'admin', 'Guest ', 'hash', 'url', 'locale') VALUES
  
  
(1, 'Guest ', 'Guest user', '', 0, 0, NULL, 0, 1, NULL ),
  
  
(2, 'admin', 'gallery Administrator ', '', 0, 0, 'unknown @ unknown.com', 1, 0, NULL)
 
 

The above is the process of creating a user table in the MySQL database and setting its ID as an auto-incrementing column. This article will introduce it here. I hope this introduction will be helpful to you!
