Dear list I have a csv file having the following contents. col1 col2 col3 "A", "1","2" "B","1", "3" "C","2","4" "D","1","5" "A","1","6" "B","2","7" "C","2","8" " ","3","9"
Now I want to implement a logic which will show me the summarize records as follows col1 count A- 2 B - 2 C - 2 D - 1 and one more question how the null value will be handled Thanks & Regards Anirban Adhikary.
