How to insert/update a csv file by comparing it with another csv file? for example, i have 2 input files :
ColA ColB ColC
1 A AA
2 B AB
3 C CC
and second one :
ColA ColB ColC
2 B BB
4 D DC
Job should compare these 2 files and update the records present in first input file. so the output file will look like this:
ColA ColB ColC
1 A AA
2 B BB
