Use the UPDATE. I assume you mean by "database" here you mean the database table named "members"... if so, try the following query.
UPDATE members SET user_name = 'john_doe' WHERE user_name = 'John Doe';

Hi, I am not a database person. I have a database called "members". One of the fields in this database is "user_name". There are a number of records in this database. Under the field user_name, I would like to make some changes manually; for example, I want to change
John Doe
to
john_doe
Is it possible to do it? How do I do it? Thank you very much in advance.
