Get values from all rows and display it a single row separated by comma with MySQL

For this, use GROUP_CONCAT(). Do not use GROUP BY clause, since GROUP_CONTACT() is a better and quick solution.

Let us first create a table −

mysql> create table DemoTable1371    -> (    -> Id int,    -> CountryName varchar(40)    -> ); Query OK, 0 rows affected (0.89 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1371 values(100,'US'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1371 values(100,'UK'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable1371 values(101,'AUS'); Query OK, 1 row affected (0.27 sec) mysql> insert into DemoTable1371 values(101,'Angola'); Query OK, 1 row affected (0.14 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1371;

This will produce the following output −

+------+-------------+ | Id   | CountryName | +------+-------------+ |  100 | US          | |  100 | UK          | |  101 | AUS         | |  101 | Angola      | +------+-------------+ 4 rows in set (0.00 sec)

Here is the query to get values from all rows and display it a single row separated by comma −

mysql> select group_concat(CountryName separator ',') from DemoTable1371;

This will produce the following output −

+-----------------------------------------+ | group_concat(CountryName separator ',') | +-----------------------------------------+ | US,UK,AUS,Angola                        | +-----------------------------------------+ 1 row in set (0.00 sec)
