mass change text at all posts

[dimitris]

well, i need a hack that it make a mass change at the users posts one word to another.

I mean, a hack which i will give a word , like dady, and it changes as "Mamy" at all the post. This hack is like chensorship (there is NOT advansed censorship for 3.5.x yet), but for now a mass change text hack will be ok.

It will be usefull for some old bbcode word, or some old hacks from 3.0.x

Maybe this change can be and from db. I can find the order to find all the post which has a specific word from a db, and is:
SELECT `pagetext` FROM `post` WHERE `pagetext` LIKE '%dady%'

......but i dont know what must to do to change all the inside at posts text "dady".

Thx for your time
