From your filterscript I see you're using SQlite Database Browser.
You can click "execute sql" and execute the following sql query:

Код:

UPDATE `TABLE_NAME` SET `USERNAME_FIELD` = 'Jake_Hero' WHERE `USERNAME_FIELD` = 'Ronald_Lacson'

You have to replace TABLE_NAME and USERNAME_FIELD with the name of the table and the name of the username field in your database.
