Are there any types of aggregate functions that could help calculate the following?
If I have the following data, I want the sum total for each duplicated row.
date | country | color | measure | left | position --------------------------------------------------------------- 2020-02-01 united states red 33 5.3 none 2020-02-01 united states red 33 5.3 none 2020-02-01 united states red 33 5.3 none 2020-02-03 vietnam green 44 9.2 none 2020-02-01 united states red 33 5.3 none 2020-02-01 united states red 33 5.3 none 2020-02-03 vietnam green 44 9.2 none 2020-02-01 canada yellow 20 3.1 none 2020-02-06 mexico orange 2 9.0 miss 2020-02-06 mexico red 1 3.0 none
The output would provide total number each row occurs:
date | country | color | measure | left | position | total ----------------------------------------------------------------------- 2020-02-01 united states red 33 5.3 none 5 2020-02-03 vietnam green 44 9.2 none 2 2020-02-01 canada yellow 20 3.1 none 1 2020-02-06 mexico orange 2 9.0 miss 1 2020-02-06 mexico red 1 3.0 none 1
