I have searched a lot but could not find any specific example related to this problem, so I am posting this question.
I have data in CSV format that I load in MongoDB compass. It has a DateTime field of type Date and user field of type int and also calories field of type double.
What I want to do is.
I want to query the average calories during morning, evening, and night in a specific month but could not write the right query.
I want to aggregate the data for all the attributes by time
intervals into the morning, day, night, and store this data in the database.
That means that I have to split the data into 3 sections: 7 am-12:pm, 12:01-7:00 pm and
7:01pm-6:59am. Get the averages of these values between these
times for each attribute and store the data in the database.
Here is an image of data
Thanks all.
