I have a dataset with a START_DATE column and a string column like this:
START_DATE string
2017-03-31 a
2017-04-30 b
2017-05-30 c
I want to transform it into this format like this:
START_DATE string
2017-03-31 a
2017-04-30 b
2017-05-30 c
2017-06-30
2017-07-31
2017-08-31
2017-09-30
2017-10-31
2017-11-30
2017-12-31
2017-01-31
2017-02-28
2017-03-31
Is there any easy solution to this question?
Thanks!
