MySQL을 사용하여 범위의 특정 행을 선택하시겠습니까?

먼저 테이블을 생성하겠습니다 -

mysql> create table DemoTable
   (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentName varchar(20)
   );
Query OK, 0 rows affected (1.23 sec)

삽입 명령을 사용하여 테이블에 일부 레코드 삽입 -

mysql> insert into DemoTable(StudentName) values('John');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable(StudentName) values('Carol');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable(StudentName) values('David');
Query OK, 1 row affected (0.07 sec)
mysql> insert into DemoTable(StudentName) values('Bob');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(StudentName) values('Chris');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(StudentName) values('Robert');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(StudentName) values('Adam');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(StudentName) values('Mike');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(StudentName) values('Sam');
Query OK, 1 row affected (0.16 sec)

select 문을 사용하여 테이블의 모든 레코드 표시 -

mysql> select *from DemoTable;

출력

+----+-------------+
| Id | StudentName |
+----+-------------+
| 1  | John        |
| 2  | Carol       |
| 3  | David       |
| 4  | Bob         |
| 5  | Chris       |
| 6  | Robert      |
| 7  | Adam        |
| 8  | Mike        |
| 9  | Sam         |
+----+-------------+
9 rows in set (0.00 sec)

다음은 특정 행을 선택하는 쿼리입니다. MySQL −

mysql> select *from DemoTable ORDER BY Id DESC LIMIT 4 OFFSET 2;

출력

+----+-------------+
| Id | StudentName |
+----+-------------+
| 7  | Adam        |
| 6  | Robert      |
| 5  | Chris       |
| 4  | Bob         |
+----+-------------+
4 rows in set (0.00 sec)
