The Trim() function is used to remove new line characters from data rows in MySQL. Let us see an example. First, we will create a table. The CREATE command is used to create a table.
mysql> create table tblDemotrail - > ( - > id int, - > name varchar(100) - > ); Query OK, 0 rows affected (0.57 sec)
Let us now insert some records.
mysql> insert into tblDemotrail values(1,'John '); Query OK, 1 row affected (0.15 sec) mysql> insert into tblDemotrail values(2,' Carol'); Query OK, 1 row affected (0.32 sec) mysql> insert into tblDemotrail values(3,' Sam '); Query OK, 1 row affected (0.17 sec) mysql> insert into tblDemotrail values(4,' Tom\n '); Query OK, 1 row affected (0.18 sec) mysql> insert into tblDemotrail values(5,' \nTim '); Query OK, 1 row affected (0.12 sec)
Let us display all the records.
mysql> select *from tblDemotrail;
The following is the output that doesn’t look like normal record, since we included newline characters while adding records.
+------+------------------+ | id | name | +------+------------------+ | 1 |John | | 2 | Carol | | 3 | Sam | | 4 | Tom | | 5 |Tim | +------+------------------+ 5 rows in set (0.00 sec)
To remove new line characters, you need to use the following query.
mysql> update tblDemotrail SET name = TRIM(TRAILING '\n' FROM name); Query OK, 0 rows affected (0.00 sec) Rows matched: 5 Changed: 0 Warnings: 0
