Compare 2 files & extract subset of records from file2

Postby er_hariharan » Tue Apr 28, 2009 10:08 am

Hi
Can anyone please assist me with this? Need to compare two files and extracting a subset of records from second file based on a criteria.

Requirement :
Basically, I do receive FILE1 and FILE2 from my existing procedure. Since it is an external procedure, I do not know exactly what value is present in FILE1 and am trying to have this file comparison and extract as a generic procedure for future runs.

I need to compare FILE1 & FILE2 and based on the value of a date field (CCYY format) in FILE1 mapping with a date field in FILE2, need to extract the records from FILE2.
Please find the files and details below :

FILE1
------

----+----1----+----2----+----3----+----4----+----5----+----6----+----7--
RCH SAM01
RCD2006SAMUEL
RCT SAM01
RCH HENDERSON01
RCD2006HENDERSON
RCT HENDERSON01
RCH VAUGHN01
RCD2006VAUGHN
RCT VAUGHN


Need to extract the year part from the above file (pos : 4-7 ;length = 4 bytes) which will only be present in the record

containing the first 3 bytes as "RCD" (pos : 1-3; length = 3 bytes) RECFM=FB
Note : FILE1 will always carry the same date value in all the RCD record.



FILE2

RECFM=FB, POS : 24 ; Length = 4 bytes is the date field


Requirement :
---------------
Need to compare FILE1 & FILE2 and extract the full record from FILE2 for which the date field in FILE2 < date field in

FILE1

i.e., if date value in FILE1 = 2006, then the records with date value "2005, 2004, 2003, 2002" from FILE2 must be

extracted.


I did a try using JOINKEYS option. It filtered out the unpaired keys (I specified the date fields as key fields ) but it

also showed the year 2007, 2008 records.

Is it possible to do using JOINKEYS/SPLICE option or any other way.

Test JCL that I used :

EXPECTED OUTPUT :
-------------------
I Thought of appending FILE1 data to the last 4 byte of FILE2 (pos : 73 - 76) and then compare with pos 69 - 72 and

subset only the records which have date < 2006. But ended with blanks populated in pos : 73 - 76 except for one record having 2006.

The desired output FILE2 should contain :

----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+-

Hello,

You have posted your question in the DFSORT part of the forum, but you have posted syntax that is not supported by DFSORT.

Your topic has been moved to Syncsort.
Hope this helps,
d.sch.

Hi
I tried again in an alternative way and got the result.
Here is the modified JCL :
