PL/SQL :: Query To Identify Delimiter From Data?

I am trying to write a code to identify the delimiter in the file ( which is in the form of table(id, raw) in system)then I take this delimiter and pass it as a parameter to SP which perform cleaning of this file(table) and creates another clean table.

The problem I am facing is until now the file was coming with one fixed (TAB) delimiter, but now it has come with different (SPACE), now here I want to develop the code to identify the delimiter place it in a variable an pass this as parameter to cleaning SP.

--here i want to develop code to identify delimiter from hosts_equiv file which has data as below

select * from hosts_equiv where left(raw,1) not in ('#','*') and isnull(raw,'')<>''

Raw                  id
----------------        ---
hiper USER1        1
hiper2 USER1      2 
APX    user2       3

Need to identify delimiter between e.g. hiper USER1  and pass it as a parameter to the raw_parse sp

declare Tab  varchar(10)
set Tab = char(9)
exec raw_Parse
'hosts_equiv',   -- From table ( entire file content is stored as table with Id record no sequence generated)
'CleanedHosts_Equiv', -- To table name, when passed it will clean the from table and places the cleaned data in to_table

[code]....
