We can perform regular expression replace in MySQL using the REGEXP_REPLACE(~)
method.
Example
Consider the following table about some students:
student_id | fname | lname | day_enrolled | age | username |
---|---|---|---|---|---|
1 | Sky | Towner | 2015-12-03 | 17 | stowner1 |
2 | Ben | Davis | 2016-04-20 | 19 | bdavis2 |
3 | Travis | Apple | 2018-08-14 | 18 | tapple3 |
4 | Arthur | David | 2016-04-01 | 16 | adavid4 |
5 | Benjamin | Town | 2014-01-01 | 17 | btown5 |
The above sample table can be created using the code here.
To replace all lowercase characters in student usernames with '-'
:
SELECT username, REGEXP_REPLACE(username, '[a-z]', '-', 1, 0, 'c')FROM students;
+----------+---------------------------------------------------+| username | REGEXP_REPLACE(username, '[a-z]', '-', 1, 0, 'c') |+----------+---------------------------------------------------+| stowner1 | -------1 || bdavis2 | ------2 || tapple3 | ------3 || adavid4 | ------4 || btown5 | -----5 |+----------+---------------------------------------------------+
