MySQL – remove non numeric and non commas from string

There are tons of answers how to remove non numeric characters:

REGEXP_REPLACE('áőüóöúeád1.23asd12,333-%!', '[^0-9]', '');

but I also need to keep the commas so the result would be:

12312,333

how to do that?

>Solution :

Just include the comma in the regex. '[^0-9,]'
