Get unique values and the respective count..

Postby manojul22 » Fri Oct 26, 2012 5:19 pm

Requirement
I need to get the unique values and the respective counts.
Sample Input
|abc|^qwef|^asdr|^zxc|^
|^abc|^zxc|
|abc|^qwef|^asdr|^zxc|^
|^abc|^zxc|^abc|^zxc
Expected output
abc 5
qwef 2
asdr 2
zxc 5
I have 1.4 million records which is the unload of one specific field(var char) from a DB2 table.
The record can have n number of values(like abc, qwef etc) the length is also not fixed.

Please suggest.

What do the "carats" indicate?

You mean NL or you mean LF? So you have strings of different lengths, some with a byte with a non-display value leading or trailing, some fields solely with the non-display. And you want counts of each different, ignoring any of the non-display characters present - and the fields are delimited by the pipe, your file is VB. Is there a maximum number of fields on a record? What is the LRECL? Maximum lenght of a field? Do you want the "empty" fields counted?
