Sorting on common fields with duplicates in the input files.

Postby Abhijat » Tue Aug 18, 2009 11:54 pm

Hi,
I have following 2 files:
File1: Fields (X,A,B) File is sorted on the basis of the fields A and B asc
Select all
LLLLLL AAAAAA 00000000000000000000000000
LLLLLL AAAAAA 11111111111111111111111111
MMMMMM AAAAAA 11111111111111111111111111
OOOOOO BBBBBB 00000000000000000000000000
PPPPPP BBBBBB 33333333333333333333333333
NNNNNN CCCCCC 00000000000000000000000000

File2: Fields (A,B,Z) File is sorted on the basis of the fields A and B asc
Select all
AAAAAA   11111111111111111111111111   DATA01

Final output file expected as:
Select all
LLLLLL AAAAAA 11111111111111111111111111
MMMMMM AAAAAA 11111111111111111111111111

NNNNNN CCCCCC 00000000000000000000000000


Now I need to get an output file with only the details from the file1 which have a matching values for the fields A and B from both the files. Please note that both the files can have duplicates on the joining fields. I will need to have the duplicates retained in the output file from file1. I tried a lot of combinations, but am not able to get to the final results due to the duplicates present in both the input files. Can someone please help me out here?

Hello and welcome to the forum,

It will probably help if you post what you have coded so far and what happens when you run it.
Hope this helps,

Hi Abhijat,
Following sort should give you the results as you are intending
