As shown in the picture, I want to get the specific values by date.
Someone told me to treat the csv file as a SQL and retrieve the data that I want to find by query.
I haven't used SQL before so I am not sure what query I need to write.
For example, if I want to get the values from Column D where the dates are between 26-Mar-21 to 05-Apr-21, how I should write the query?
(I think there is no table name for the date in the above csv file)
Thanks in advance!
