Sql to remove brackets non ascii charaters

Question

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
Hi there,
I have a requirement to remove the any non alphabets like brackets, , quotes and non ascii, languages other than english and everything in lower case. The select is simple
select
lower(customer_name)
from
  customer_data
where  CONVERT ( customer_name, 'US7ASCII')     = customer_nameHowever, I also want to add maybe the replace function on the customer name, such that the brackets, ", ', / - or any other such character can be removed. I tried unsuccessfully something like
{code}
select replace('cvp, llc','''-/,,".') from dual
I wanted to do something on those lines on my first query so that I only get english alphabets customer names, stripping off all the non english charaters and any non-english characters.
Could you please advise?
Thanks,
Ryan

Hi Chris,
if you want to use TRANSLATE then you have to modify it a bit:
WITH customer_data AS
   SELECT 'cvp, llc' AS customer_name FROM DUAL
SELECT translate(customer_name,'abcdefghijklmnopqurstuvwxyzABCDEFGHIJKLMNOPQURSTUVWXYZ1234567890'
                ,'abcdefghijklmnopqurstuvwxyzABCDEFGHIJKLMNOPQURSTUVWXYZ1234567890') txt
  FROM customer_data;
TXT    
cvp, llc
WITH customer_data AS
   SELECT 'cvp, llc' AS customer_name FROM DUAL
WITH customer_data AS
   SELECT 'cvp, llc' AS customer_name FROM DUAL
SELECT translate(customer_name,' '
                 ||'[''-/,".]' -- chars to remove here
                ,' ') txt
  FROM customer_data;
TXT   
cvp llc
{code}
Regards.
