Cannot use group by and over(partition by) in the same query?

Question

I have a table myTable with 3 columns. col_1 is an INTEGER and the other 2 columns are DOUBLE. For example, col_1={

Answer 1

I found the solution.

I do not need to use OVER(PARTITION BY col_1) because it is already in the GROUP BY clause. Thus, the following query gives me the right answer:

SELECT col_1, col_2, sum(Value) as sum_value
from myTable GROUP BY col_1, col_2

since I am already grouping w.r.t col_1 and col_2.

Dave, thanks, I got the idea from your post.
