I am having a hash file with IP_ID, IA,ID as the key columns and there are some records with spaces in these columns comming from source . I am trimming those columns and writing into the hash file from a seq file.
The problem i am facing is that after triming the columns are not containing blank spaces but they are havind some non printable character because of which the look up's are failing
can i have a blank string(string of length 0) in a key colum of hash file???
Having problem with hash file
