Equaivalent of Oracle concatenation operator in MySQL?

MySQLMySQLi Database

The concat operator can be used in ORACLE. MySQL use concat() function to perform concatenation.

To understand the concat() function, let us create a table. The query to create a table is as follows −

mysql> create table ConcatenationDemo
   −> (
   −> Id int,
   −> Name varchar(100)
   −> );
Query OK, 0 rows affected (0.86 sec)

Insert some records in the table using insert command. The query is as follows −

mysql> insert into ConcatenationDemo values(100,'John');
Query OK, 1 row affected (0.19 sec)

mysql> insert into ConcatenationDemo values(101,'Sam');
Query OK, 1 row affected (0.25 sec)

mysql> insert into ConcatenationDemo values(102,'Johnson');
Query OK, 1 row affected (0.15 sec)

mysql> insert into ConcatenationDemo values(103,'Carol');
Query OK, 1 row affected (0.26 sec)

mysql> insert into ConcatenationDemo values(104,'Bob');
Query OK, 1 row affected (0.13 sec)

Display all records from the table using select statement. The query is as follows −

mysql> select *from ConcatenationDemo;

The following is the output −

+------+---------+
| Id   | Name    |
+------+---------+
|  100 | John    |
|  101 | Sam     |
|  102 | Johnson |
|  103 | Carol   |
|  104 | Bob     |
+------+---------+
5 rows in set (0.00 sec)

Here is the query to perform concatenation in MySQL −

mysql> select concat('(',Id,',',Name,')') as ConcatIdAndName from ConcatenationDemo;

The following is the output displaying the concatenated result −

+-----------------+
| ConcatIdAndName |
+-----------------+
| (100,John)      |
| (101,Sam)       |
| (102,Johnson)   |
| (103,Carol)     |
| (104,Bob)       |
+-----------------+
5 rows in set (0.00 sec)
