use REPLACE()

UPDATE tableName
SET first_name = REPLACE(first_name, 'a', 'b')

but remember that REPLACE() is case sensitive.

is there another function that is not case sensitive ?, or a parameter we can pass to REPLACE ? – Francisco Corrales Morales Sep 22 '14 at 21:19

You can try this:

UPDATE name SET first_name = REPLACE (first_name, 'a', 'b') WHERE blabla LIKE '%blabla%';
OR
UPDATE name SET first_name = REPLACE (first_name, 'a', 'b') WHERE blabla = 'blabla';
