Hi All,
I have a merchant order data, there are two columns "Contract Star Date" and "Contract End Date". The Aim is to find the contract period.
Now, for some orders in "Contract Start Date" Years are mentioned like 2014, 2015, etc. and wherever the values were not given "Unknown is mentioned"
Similarly in "Contract End Date" Years are mentioned like 2014, 2015, etc. and wherever the values were not given "Unknown is mentioned"
Question: What datatype we should select for such columns? and How to calculate the contract period?
Below is the sample
Thanks in Advance.
