How to get a specific column record from SELECT query in MySQL?

Let us first create a table −

mysql> create table DemoTable1837
     (
     StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
     StudentName varchar(20)
     );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1837(StudentName) values('Chris');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1837(StudentName) values('David');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1837(StudentName) values('Bob');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1837(StudentName) values('Mike');
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1837;

This will produce the following output −

+-----------+-------------+
| StudentId | StudentName |
+-----------+-------------+
|         1 | Chris       |
|         2 | David       |
|         3 | Bob         |
|         4 | Mike        |
+-----------+-------------+
4 rows in set (0.00 sec)

Here is the query to get a specific column records:

mysql> select StudentName from DemoTable1837;

This will produce the following output −

+-------------+
| StudentName |
+-------------+
| Chris       |
| David       |
| Bob         |
| Mike        |
+-------------+
4 rows in set (0.00 sec)
