How do you append a carriage return to a value in MySQL?
You need to use CONCAT_WS() function from MySQL to append a carriage return. If you are looking for a new line, then append
in the beginning. The syntax is as follows −
SELECT CONCAT_WS(‘
’,yourColumnName) as anyVariableName from yourTableName;
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table NewLineDemo -> ( -> CountryName varchar(10) -> ); Query OK, 0 rows affected (0.50 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into NewLineDemo values('US');
Query OK, 1 row affected (0.15 sec)
mysql> insert into NewLineDemo values('UK');
Query OK, 1 row affected (0.13 sec)
mysql> insert into NewLineDemo values('AUS');
Query OK, 1 row affected (0.11 secDisplay all records from the table using select statement. The query is as follows:
mysql> select *from NewLineDemo;
The following is the output −
+-------------+ | CountryName | +-------------+ | US | | UK | | AUS | +-------------+ 3 rows in set (0.00 sec)
Here is the query for a list of values using CONCAT_WS(). In this function the first parameter will be ‘
’ for new line. The query is as follows:
mysql> select concat_ws('
',CountryName) as CountryList from NewLineDemo;The following is the output −
+-------------+ | CountryList | +-------------+ | US | | UK | | AUS | +-------------+ 3 rows in set (0.00 sec)
Or you can understand the above query like this. If all values are separated with comma, the query is as follows −
mysql> select concat_ws('
','US','UK','AUS') as CountryName;The following is the output −
+-------------+ | CountryName | +-------------+ | US | | UK | | AUS | +-------------+ 1 row in set (0.00 sec)
