mysql 查看表结构
1、desc tablename;
例如 :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 | |
+------------------+---------------------+------+-----+---------------------+----------------+
2、show create table tablename;
例如:show create table 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=utf8;
3、use information_schema;
select * from columns where table_name='tablename';
例如:
use information_schema;
select * from columns where table_name='jos_modules';
