如何显示MySQL数据库中表的架构？

为了显示模式，我们可以使用DESC命令。这给出了关于表结构的描述。

以下是语法。

DESCRIBE yourDatabasename.yourTableName;

让我们实现以上语法。

mysql> DESCRIBE business.student;

以下是输出。

+-------+--------------+------+-----+---------+-------+
| Field | Type         | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| id    | int(11)      | YES  | MUL | NULL    |       |
| Name  | varchar(100) | YES  | MUL | NULL    |       |
+-------+--------------+------+-----+---------+-------+
2 rows in set (0.05 sec)

借助show create table命令显示表架构的语法。

show create table yourDatabasename.yourTableName;

以下是查询。

mysql> show create table business.student;

这是显示架构的输出。

+---------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

| student | CREATE TABLE `student` (`id` int(11) DEFAULT NULL,
   `Name` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
   KEY `NameStuIndex` (`Name`),
   KEY `idIndex` (`id`)
)  ENGINE = InnoDB
