LONG RAW data types works the same as varchar2.

declare
l2 long raw;
l1 long raw;
begin
select raw_col INTO l2 from <tableA>;
l1:=substr(l2, 356789,55);
end;
/

The function RAWTOHEX converts raw to a character value containing its hexadecimal equivalent.

user chr function to convert the ascii value to the character. This has to be done for each character.

Oracle supplied package UTL_RAW has many functions to manipulate RAW DATA.

Are you looking for RAW to VARCHAR2 conversion using utl_raw.cast_to_varchar2??
