如何获取MySQL表列的名称？
您可以为此使用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) );
以下是获取我的MySQL表列名称的查询-
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 | | | StudentAddress | varchar(200) | YES | | NULL | | +------------------+--------------+------+-----+---------+----------------+ 5 rows in set (0.01 sec)
