计算每个日期的值的总和，并返回最高的总和

Question

I have the following theoretical fields: Date and Hours Played and three rows:

• 1st row: the Date column has the value "1/12/2016", while the Hours Played column has the value "2".

• 2nd row: the Date column has the value "1/12/2016", while the Hours Played column has the value "2".

• 3rd row: the Date column has the value "1/06/2016", while the Hours Played column has the value "3.5".

If I use the =MAX() function, the day with the most hours played will be 1/06/2016 with 3.5 hours. However, in reality the day with the most hours played is 1/12/2016 with 4 hours total.

Does anyone know of a function to use that would return the highest sum of the hours played for each date (in this case: 4 ).

Answer 1

The query function is appropriate here. If the dates are in column A and hours are in column B, it could look like

=query(A:B, "select sum(B) group by A order by sum(B) desc limit 1 label sum(B) ''")

Meaning: sum B, grouping by A, return the highest value, don't label it.
