查看mysql表结构的方法有三种：1、desc tablename;例如：要查看jos_modules表结构的命令：desc jos_modules;查看结果：mysql> desc jos_modules;+------------------+---------------------+------+-----+---------------------+----------------+| Field            | Type                | Null | Key | Default             | Extra          |+------------------+---------------------+------+-----+---------------------+----------------+| id               | int(11)             | NO   | PRI | NULL                | auto_increment || title            | text                | NO   |     | NULL                |                || content          | text                | NO   |     | NULL                |                || ordering         | int(11)             | NO   |     | 0                   |                || position         | varchar(50)         | YES |     | NULL                |                || checked_out      | int(11) unsigned    | NO   |     | 0                   |                || checked_out_time | datetime            | NO   |     | 0000-00-00 00:00:00 |                || published        | tinyint(1)          | NO   | MUL | 0                   |                || module           | varchar(50)         | YES | MUL | NULL                |                || numnews          | int(11)             | NO   |     | 0                   |                || access           | tinyint(3) unsigned | NO   |     | 0                   |                || showtitle        | tinyint(3) unsigned | NO   |     | 1                   |                || params           | text                | NO   |     | NULL                |                || iscore           | tinyint(4)          | NO   |     | 0                   |                || client_id        | tinyint(4)          | NO   |     | 0                   |                || control          | text                | NO   |     | NULL                |                |+------------------+---------------------+------+-----+---------------------+----------------+2、show create table tablename;例如：要查看jos_modules表结构的命令：show create table jos_modules;查看结果：mysql> show create table jos_modules;jos_modules | CREATE TABLE `jos_modules` (`id` int(11) NOT NULL AUTO_INCREMENT,`title` text NOT NULL,`content` text NOT NULL,`ordering` int(11) NOT NULL DEFAULT '0',`position` varchar(50) DEFAULT NULL,`checked_out` int(11) unsigned NOT NULL DEFAULT '0',`checked_out_time` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',`published` tinyint(1) NOT NULL DEFAULT '0',`module` varchar(50) DEFAULT NULL,`numnews` int(11) NOT NULL DEFAULT '0',`access` tinyint(3) unsigned NOT NULL DEFAULT '0',`showtitle` tinyint(3) unsigned NOT NULL DEFAULT '1',`params` text NOT NULL,`iscore` tinyint(4) NOT NULL DEFAULT '0',`client_id` tinyint(4) NOT NULL DEFAULT '0',`control` text NOT NULL,PRIMARY KEY (`id`),KEY `published` (`published`,`access`),KEY `newsfeeds` (`module`,`published`)) ENGINE=MyISAM AUTO_INCREMENT=145 DEFAULT CHARSET=utf83、use information_schema;select * from columns where table_name='tablename'例如：要查看jos_modules表结构的命令：use information_schema;select * from columns where table_name='jos_modules';查看结果：略。如果要查看怎么建立数据表的命令用第二种方法最佳。
