MySQL 如何获取表的列名

您可以使用SHOW命令。

以下是语法 –

show columns from yourTableName;

让我们首先创建一个表 –

mysql> create table DemoTable
(
   StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentFirstName varchar(20),
   StudentLastName varchar(20),
   StudentAge int,
   StudentAddress varchar(200)
);
Query OK, 0 rows affected (0.54 sec)

以下是获取MySQL表的列名的查询 –

mysql> show columns from DemoTable;

这将产生以下输出 –

+------------------+--------------+------+-----+---------+----------------+
| Field            | Type         | Null | Key | Default | Extra          |
+------------------+--------------+------+-----+---------+----------------+
| StudentId        | int(11)      | NO   | PRI | NULL    | auto_increment |
| StudentFirstName | varchar(20)  | YES  |     | NULL    |                |
| StudentLastName  | varchar(20)  | YES  |     | NULL    |                |
| StudentAge       | int(11)      | YES  |     | NULL    |                |
