How to make MySQL display results in a single line?
For this, you can use group_concat(). Let us first create a table −
mysql> create table DemoTable1507 -> ( -> Name varchar(20), -> PaperSet int -> ); Query OK, 0 rows affected (0.68 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1507 values('Chris',111);
Query OK, 1 row affected (0.37 sec)
mysql> insert into DemoTable1507 values('David',112);
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable1507 values('Mike',111);
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable1507 values('Bob',113);
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1507;
This will produce the following output −
+-------+----------+ | Name | PaperSet | +-------+----------+ | Chris | 111 | | David | 112 | | Mike | 111 | | Bob | 113 | +-------+----------+ 4 rows in set (0.00 sec)
Here is the query to make MySQL display results only in a single line −
mysql> select group_concat(Name order by Name desc separator ':') -> from DemoTable1507 -> where PaperSet=111;
This will produce the following output −
+-----------------------------------------------------+ | group_concat(Name order by Name desc separator ':') | +-----------------------------------------------------+ | Mike:Chris | +-----------------------------------------------------+ 1 row in set (0.00 sec)
