Reemplazar cadenas de caracteres en MySql





Para reemplazar una cadena de texto por otra, sin necesidad de estar tupla a tupla:

UPDATE `tabla` SET campo = REPLACE(campo,'texto a buscar','nuevo texto');

Y si por ejemplo queremos actualizar un determinado campo comprendido entre una fecha:

UPDATE `tabla` SET campo = REPLACE(campo,'texto a buscar','nuevo texto') WHERE fecha BETWEEN '2012-06-01' AND '2012-06-31';
