SELECT * FROM 'table' WHERE `name` REGEXP '\r'

UPDATE 'table' SET 'field' = replace(field,"findvalue", "reaplcevalue") WHERE REGEXP 'regexp search expression'

After a problem with row break in a text field I found this way of searching within a where clause in an SQL query. Can be used for selection or update / replace purposes of course.
