Display all the column values in a single row separated by comma in MySQL?
For this, use GROUP_CONCAT() and CONCAT(). Let us first create a table −
mysql> create table DemoTable1807 ( Id int ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1807 values(101); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1807 values(102); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1807 values(103); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1807;
This will produce the following output −
+------+ | Id | +------+ | 101 | | 102 | | 103 | +------+ 3 rows in set (0.00 sec)
Here is the query to convert SQL query to MySQL −
mysql> select group_concat(concat('[',Id,']')) from DemoTable1807;
This will produce the following output −
+----------------------------------+
| group_concat(concat('[',Id,']')) |
+----------------------------------+
| [101],[102],[103] |
+----------------------------------+
1 row in set (0.00 sec)
