Is there any alternative for CONCAT() in MySQL?

Yes, an alternative is CONCAT_WS(). Let us first create a table −

mysql> create table DemoTable
   (
   StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentName varchar(100)
   );
Query OK, 0 rows affected (0.74 sec)

Example

Insert some records in the table using insert command −

mysql> insert into DemoTable(StudentName) values('Chris');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(StudentName) values('Robert');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable(StudentName) values('Bob');
Query OK, 1 row affected (0.12 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

Output

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

Let us see how to work with an alternative of CONCAT() in MySQL −

mysql> select concat_ws(SPACE(2), 'Student Name is:',StudentName) from DemoTable;

Output

+-----------------------------------------------------+
| concat_ws(SPACE(2), 'Student Name is:',StudentName) |
+-----------------------------------------------------+
| Student Name is: Chris                              |
| Student Name is: Robert                             |
| Student Name is: Bob                                |
+-----------------------------------------------------+
