从几组数据中，将每个Id的最大数字相加

Question

I have 3 sets of data, all consisting of 1 column with a list of unique IDs and the other with integers. Some of the unique IDs (with their integer) appear in more than 1 set, others don't.

ColA        ColB        ColD        ColE        ColF        ColG
UniqueIDs1  Integers1   UniqueIDs2  Integers2   UniqueIDs3  Integers3

I want to sum all the integers in all sets, BUT if there's a duplicate, only sum the highest between the 3 (or the 2 if the match is only between 2 sets).

How can I do that?

Answer 1

The following formula computes such a sum.

=sum(query({A:B; D:E; F:G}, "select max(Col2) group by Col1"))

1. {A:B; D:E; F:G} {A:B; D:E; F:G} stacks the columns of your sheet (you may want to use A2:B if 1st row are headers). The result is an array with two columns, Id in Col1, and integer in Col2.
2. Query selects the maximal element of second column for each Id.
3. Sum adds those.
