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)
