Is there a way to select a value which matches partially in MySQL?

To match partially, use LIKE operator. Let us first create a table −

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)

Insert some records in the table using insert command −

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)

Display all records from the table using select statement −

mysql> select *from DemoTable806;

This will produce the following output −

+-----------+-------------+------------------------------------------------+
| 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)

Following is the query to select a value which matches partially −

mysql> select *from DemoTable806 where StudentSubject LIKE '%Depth%';

This will produce the following output −

+-----------+-------------+------------------------------------------------+
| StudentId | StudentName | StudentSubject                                 | 
+-----------+-------------+------------------------------------------------+
|         1 | Chris       | Java in Depth With Data Structure              |
|         3 | Bob         | C++ in Depth With Data Structure And Algorithm |
+-----------+-------------+------------------------------------------------+
