Given this dbt model SQL snippet, what will be the output columns?

SELECT user_id, COUNT(*) AS order_count
FROM {{ ref('orders') }}
GROUP BY user_id

AAn error because GROUP BY is missing

CAll columns from orders table without aggregation

Duser_id and order_count columns with counts per user

Step-by-Step Solution

Solution:

Step 1: Analyze SELECT and GROUP BY
The query selects user_id and counts rows grouped by user_id, so output has user_id and order_count.
Step 2: Confirm aggregation correctness
GROUP BY user_id matches the aggregation COUNT(*), so query runs correctly and outputs two columns.
Final Answer:
user_id and order_count columns with counts per user -> Option D
Quick Check:
GROUP BY user_id + COUNT(*) = user_id, order_count [OK]

Quick Trick: GROUP BY columns appear with aggregated counts [OK]
