부분적으로 일치시키려면 LIKE 연산자를 사용하십시오. 먼저 테이블을 생성하겠습니다 -
mysql> create table DemoTable806( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentName varchar(100), StudentSubject varchar(100) ); Query OK, 0 rows affected (0.57 sec)
삽입 명령을 사용하여 테이블에 일부 레코드 삽입 -
mysql> insert into DemoTable806(StudentName,StudentSubject) values('Chris','Java in Depth With Data Structure');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable806(StudentName,StudentSubject) values('Robert','Introduction to MySQL');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable806(StudentName,StudentSubject) values('Bob','C++ in Depth With Data Structure And Algorithm');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable806(StudentName,StudentSubject) values('Adam','Introduction to MongoDB');
Query OK, 1 row affected (0.11 sec) select 문을 사용하여 테이블의 모든 레코드 표시 -
mysql> select *from DemoTable806;
이것은 다음과 같은 출력을 생성합니다 -
+-----------+-------------+------------------------------------------------+ | StudentId | StudentName | StudentSubject | +-----------+-------------+------------------------------------------------+ | 1 | Chris | Java in Depth With Data Structure | | 2 | Robert | Introduction to MySQL | | 3 | Bob | C++ in Depth With Data Structure And Algorithm | | 4 | Adam | Introduction to MongoDB | +-----------+-------------+------------------------------------------------+ 4 rows in set (0.00 sec)
다음은 부분적으로 일치하는 값을 선택하는 쿼리입니다 -
mysql> select *from DemoTable806 where StudentSubject LIKE '%Depth%';
이것은 다음과 같은 출력을 생성합니다 -
+-----------+-------------+------------------------------------------------+ | StudentId | StudentName | StudentSubject | +-----------+-------------+------------------------------------------------+ | 1 | Chris | Java in Depth With Data Structure | | 3 | Bob | C++ in Depth With Data Structure And Algorithm | +-----------+-------------+------------------------------------------------+ 2 rows in set (0.00 sec)
