먼저 테이블을 생성하겠습니다 -
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, CustomerName varchar(20), ProductPrice int ); Query OK, 0 rows affected (0.70 sec)
삽입 명령을 사용하여 테이블에 일부 레코드 삽입 -
mysql> insert into DemoTable(CustomerName,ProductPrice) values('Chris',600); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable(CustomerName,ProductPrice) values('David',450); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable(CustomerName,ProductPrice) values('Chris',980); Query OK, 1 row affected (0.40 sec) mysql> insert into DemoTable(CustomerName,ProductPrice) values('Mike',1200); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable(CustomerName,ProductPrice) values('Chris',400); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable(CustomerName,ProductPrice) values('David',1200); Query OK, 1 row affected (0.20 sec)
select 문을 사용하여 테이블의 모든 레코드 표시 -
mysql> select *from DemoTable;
이것은 다음과 같은 출력을 생성합니다 -
+----+--------------+--------------+ | Id | CustomerName | ProductPrice | +----+--------------+--------------+ | 1 | Chris | 600 | | 2 | David | 450 | | 3 | Chris | 980 | | 4 | Mike | 1200 | | 5 | Chris | 400 | | 6 | David | 1200 | +----+--------------+--------------+ 6 rows in set (0.00 sec)
다음은 특정 범위의 숫자를 표시하는 쿼리입니다 -
mysql> select CustomerName,sum(ProductPrice) AS Total_Price from DemoTable group by CustomerName having sum(ProductPrice) between 1600 and 2000 order by CustomerName DESC;
이것은 다음과 같은 출력을 생성합니다 -
+--------------+-------------+ | CustomerName | Total_Price | +--------------+-------------+ | David | 1650 | | Chris | 1980 | +--------------+-------------+ 2 rows in set (0.00 sec)
