how to ssr more than one string in a table at the same time

I would like to replace for more than one condition:

Example:

tab:([]a:`a`b`c;b:("abc-d";"rdf,e";"ertfg"))

update b:{ssr[x;"-"|",";" "]} each b from tab

I couldn't replace for both - and , at the same time, it can only take one. I tried to join each both with b but it doesn't work well.

You can achieve this using over (/)

q)update ssr/[;("-";",");" "]each b from tab
a b
---------
a "abc d"
b "rdf e"
c "ertfg"
