REPLACE()
REPLACE(string,old_element,new_element)
This function goes through the first argument and returns a string in which every occurrence of the second argument is replaced with the third argument. Here is an example:
UPDATE students, REPLACE(title, 'Mrs.', 'Ms.');
This SQL statement will retrieve each student’s title and
replace any occurrences of “Mrs.” with “Ms.” UPDATE
will change only the rows where the replacement was made.
