Differences between 2 Flat Files and process the differences
Hi
Hope you are having a great weeknd !! I had a question and need your expertise for this :

I have 2 files File1 & File2(of same structure) which I need to compare on some columns. I need to find the values which are there in File2 but not in File 1 and put the Differences in another file which I need to process

File 1
Code:
Field1 Field2 Field3 Field4 Field5 Field6
1      2      3      4      5      6
1      23     3      43     12     15

File 2
Code:
Field1 Field2 Field3 Field4  Field5 Field6
1      2      3      4       5      6
1      23     3      43      5      6 (not in diff field 5& 6 have changed which are not in compare condition)
1      23     3      12      5      6
31     43     54     5       7      8

Diff File
Code:
Field1 Field2 Field3  Field4  Field5 Field6
31     43     54      5       7      8 (in diff as its in File2 and not in File 1)
1      23     3       12      5      6 (in diff as its in File2(field4 has changed) and not in File 1)

So I need to compare only for the first 4 fields (i.e if any of those 4 fields are different then we need to pu them in the diff file and process it)


Any Help will be greatly appreciated!!

Thanks
J
