在 MySQL 中选择多个共享最小(PRICE)值的图书标题?


为此,使用 MySQL MIN()。我们首先创建 −

mysql> create table DemoTable1414
   -> (
   -> BookTitle varchar(40),
   -> BookPrice int
   -> );
Query OK, 0 rows affected (0.82 sec)

使用 insert 在表中插入一些记录 −

mysql> insert into DemoTable1414 values('Deep dive using java',560);
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable1414 values('C++ in depth',360);
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable1414 values('Data structure in C',590);
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable1414 values('Algorithm in C++',1090);
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable1414 values('Java in Depth',360);
Query OK, 1 row affected (0.33 sec)

使用 select 从表中显示所有记录 −

mysql> select * from DemoTable1414;

将生成以下输出 −

+----------------------+-----------+
| BookTitle            | BookPrice |
+----------------------+-----------+
| Deep dive using java |       560 |
| C++ in depth         |       360 |
| Data structure in C  |       590 |
| Algorithm in C++     |      1090 |
| Java in Depth        |       360 |
+----------------------+-----------+
5 rows in set (0.00 sec)

以下是查询,用于选择共享最小价格值的多个图书标题−

mysql> select BookTitle from DemoTable1414
   -> where BookPrice= ( select min(BookPrice) from DemoTable1414);

将生成以下输出 −

+---------------+
| BookTitle     |
+---------------+
| C++ in depth  |
| Java in Depth |
+---------------+
2 rows in set (0.00 sec)
