使用 MySQL IN() 显示多个选定行


我们首先创建一个表格 −

mysql> create table DemoTable1045
(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   FirstName varchar(100)
)AUTO_INCREMENT=100;
Query OK, 0 rows affected (0.62 sec)

使用 insert 命令在表格中插入一些记录 −

mysql> insert into DemoTable1045(FirstName) values('John');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1045(FirstName) values('Chris');
Query OK, 1 row affected (0.27 sec)
mysql> insert into DemoTable1045(FirstName) values('Robert');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1045(FirstName) values('Mike');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1045(FirstName) values('Adam');
Query OK, 1 row affected (0.08 sec)

使用 select 语句从表格中显示所有记录 −

mysql> select *from DemoTable1045;

这将产生以下输出 −

+-----+-----------+
| Id  | FirstName |
+-----+-----------+
| 100 | John      |
| 101 | Chris     |
| 102 | Robert    |
| 103 | Mike      |
| 104 | Adam      |
+-----+-----------+
5 rows in set (0.00 sec)

以下是用来显示多个选定行的 MySQL 查询 −

mysql> select *from DemoTable1045 tbl where(tbl.Id, tbl.FirstName) IN ((101, 'Chris'), (102, 'Robert'), (104,'Adam'));

这将产生以下输出 −

+-----+-----------+
| Id  | FirstName |
+-----+-----------+
| 101 | Chris     |
| 102 | Robert    |
| 104 | Adam      |
+-----+-----------+
3 rows in set (0.05 sec)
