How can I remove the leading and trailing spaces both at once from a string by using MySQL LTRIM() and RTRIM() functions?

For removing both leading and trailing spaces at once from a string by using LTRIM() and RTRIM() functions, we must have to use one function as an argument for other function. In other words, we must have to pass either LTRIM() function as an argument of RTIM() function or vice versa. It can be understood from the following example −

Example

Suppose we have a table ‘test_trim’ having a column ‘Name’ containing the values with leading and trailing spaces both −

mysql> Select * from test_trim;
+---------------+
| Name          |
+---------------+
| Gaurav        |
| Rahul         |
| Aarav         |
+---------------+
3 rows in set (0.00 sec)

Now the following query will remove the leading and trailing spaces at once from the names by using LTRIM() and RTRIM() functions −

mysql> Select Name, LTRIM(RTRIM(Name))AS 'Name Without Spaces' from test_trim;
+---------------+---------------------+
| Name          | Name Without Spaces |
+---------------+---------------------+
| Gaurav        | Gaurav              |
| Rahul         | Rahul               |
| Aarav         | Aarav               |
+---------------+---------------------+
3 rows in set (0.00 sec)

mysql> Select Name, RTRIM(LTRIM(Name))AS 'Name Without Spaces' from test_trim;
+---------------+---------------------+
| Name          | Name Without Spaces |
+---------------+---------------------+
| Gaurav        | Gaurav              |
| Rahul         | Rahul               |
| Aarav         | Aarav               |
+---------------+---------------------+
3 rows in set (0.00 sec)
