MySQL query to remove trailing spaces

MySQLMySQLi Database

To remove trailing space, use RTRIM() in MySQL. Let us first create a table −

mysql> create table DemoTable
   -> (
   -> FirstName varchar(50)
   -> );
Query OK, 0 rows affected (1.38 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('John ');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('Chris ');
Query OK, 1 row affected (0.51 sec)
mysql> insert into DemoTable values(' David ');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.17 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-------------------+
| FirstName         |
+-------------------+
| John              |
| Chris             |
| David             |
| Mike              |
+-------------------+
4 rows in set (0.00 sec)

Here is the MySQL query to remove trailing spaces using RTRIM() −

mysql> select rtrim(FirstName) as FirstName from DemoTable;

This will produce the following output −

+-------------+
| FirstName   |
+-------------+
| John        |
| Chris       |
| David       |
| Mike        |
+-------------+
4 rows in set (0.00 sec)
