Case when value of a group is 1 then all values of that group should be replaced by 1 - SQL

Question

I'm writing a query (using Athena - AWS) and I need to substitute all values from a group if there's at least one occurrence of another value. To exemplify:

My original dataframe

ID   v1 v2 v3
123  0  0  1
123  0  1  0
123  1  1  0
456  1  0  0 
456  0  0  0 

What I need: case when v1, v2 or v3 assume value 1 group by ID, then the whole column that contains 1 group by ID should be 1.

This is the output I need:

ID   v1 v2 v3
123  1  1  1
456  1  0  0 

Since v1, v2, v3 had at least one number 1 in the group ID 123, then all these columns for this group should be 1. However, ID 456 had at least one number 1 only in column v1, then v1 will be 1 and v2, v3 will remain 0.

Does someone know how to do that?

Answer 1

You may try the following

SELECT
   ID,
   MAX(v1) as v1,
   MAX(v2) as v2,
   MAX(v3) as v3
FROM
   your_table
GROUP BY
   ID
