如何在MySQL中显示某些列（不是全部）？

2024-05-17 11:32:05 419

为了显示某些列，请使用NOTIN并设置您不想显示的那些列。让我们首先创建一个表。以下是查询-

mysql> create table student_Information
   -> (
   -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> StudentName varchar(50),
   -> StudentAge int,
   -> StudentAddress varchar(100),
   -> StudentAllSubjectScore int
   -> );

以下是查询以显示有关上表的描述-

mysql> desc student_Information;

这将产生以下输出-

+------------------------+--------------+------+-----+---------+----------------+
| Field                  | Type         | Null | Key | Default | Extra          |
+------------------------+--------------+------+-----+---------+----------------+
| StudentId              | int(11)      | NO   | PRI | NULL    | auto_increment |
| StudentName            | varchar(50)  | YES  |     | NULL    |                |
| StudentAge             | int(11)      | YES  |     | NULL    |                |
| StudentAddress         | varchar(100) | YES  |     | NULL    |                |
| StudentAllSubjectScore | int(11)      | YES  |     | NULL    |                |
+------------------------+--------------+------+-----+---------+----------------+
5 rows in set (0.00 sec)

以下是仅显示一些列的查询-

mysql> SHOW COLUMNS FROM student_Information where field not
in('StudentAddress','StudentAllSubjectScore');

这将产生以下输出-

+-------------+-------------+------+-----+---------+----------------+
| Field       | Type        | Null | Key | Default | Extra          |
+-------------+-------------+------+-----+---------+----------------+
| StudentId   | int(11)     | NO   | PRI | NULL    | auto_increment |
| StudentName | varchar(50) | YES  |     | NULL    |                |
| StudentAge  | int(11)     | YES  |     | NULL    |                |
+-------------+-------------+------+-----+---------+----------------+
3 rows in set (0.00 sec)
