查询 MySQL 查询以从表中排除某些值


使用 NOT IN() 从表中排除一些值。

我们首先创建一个表 -

mysql> create table DemoTable791 (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   FirstName varchar(100)
);
Query OK, 0 rows affected (0.61 sec)

使用插入命令在表中插入一些记录 -

mysql> insert into DemoTable791(FirstName) values('Chris');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable791(FirstName) values('Robert');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable791(FirstName) values('David');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable791(FirstName) values('Mike');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable791(FirstName) values('Bob');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable791(FirstName) values('Carol');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable791(FirstName) values('Adam');
Query OK, 1 row affected (0.09 sec)

使用 select 语句从表中显示所有记录 -

mysql> select *from DemoTable791;

这会产生以下输出 -

+----+-----------+
| Id | FirstName |
+----+-----------+
| 1  | Chris     |
| 2  | Robert    |
| 3  | David     |
| 4  | Mike      |
| 5  | Bob       |
| 6  | Carol     |
| 7  | Adam      |
+----+-----------+
7 rows in set (0.00 sec)

下面是使用 MySQL 中的 NOT IN() 从表中排除某些值的查询 -

mysql> select *from DemoTable791 where Id NOT IN(4,5,6);

这会产生以下输出 -

+----+-----------+
| Id | FirstName |
+----+-----------+
| 1  | Chris     |
| 2  | Robert    |
| 3  | David     |
| 7  | Adam      |
+----+-----------+
4 rows in set (0.00 sec)
