1、使用的就是desc 表名查看表结构，缺点是输出的信息还不够全面。
-- desc查看表结构，也可以使用describe,desc是descride的简写，效果相同
mysql> desc info;
+-------+-----------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+-----------------------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| name | varchar(20) | YES | | NULL | |
| age | int(3) | YES | | NULL | |
| sex | enum('male','female') | YES | | NULL | |
| phone | bigint(11) | YES | | NULL | |
+-------+-----------------------+------+-----+---------+-------+
5 rows in set (0.94 sec)
mysql> describe info;
+-------+-----------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+-----------------------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| name | varchar(20) | YES | | NULL | |
| age | int(3) | YES | | NULL | |
| sex | enum('male','female') | YES | | NULL | |
| phone | bigint(11) | YES | | NULL | |
+-------+-----------------------+------+-----+---------+-------+
5 rows in set (0.08 sec)2、使用show create table语法。除了可以看到表定义之外，还可以看到engine和charset等信息。
-- desc查看表结构，也可以使用describe,desc是descride的简写，效果相同
mysql> desc info;
+-------+-----------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+-----------------------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| name | varchar(20) | YES | | NULL | |
| age | int(3) | YES | | NULL | |
| sex | enum('male','female') | YES | | NULL | |
| phone | bigint(11) | YES | | NULL | |
+-------+-----------------------+------+-----+---------+-------+
5 rows in set (0.94 sec)
mysql> describe info;
+-------+-----------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+-----------------------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| name | varchar(20) | YES | | NULL | |
| age | int(3) | YES | | NULL | |
| sex | enum('male','female') | YES | | NULL | |
| phone | bigint(11) | YES | | NULL | |
