Any ideas? We have been working through a sample query I am sharing below for any feedback from the community.

WITH campaigns (campaign_id_string, matched_behavior_segment_ids) AS (
  SELECT
    campaign_id_string,
    matched_behavior_segment_ids
FROM
    sponsored_ads_traffic
WHERE
    matched_behavior_segment_ids IS NOT NULL
    AND
    ad_product_type IN (
    'sponsored_products',
    'sponsored_brands')
),

  SELECT
    campaign,
    campaign_id_string,
    ad_product_type,
    user_id,
    matched_behavior_segment_ids,
    event_id,
    SUM(impressions) AS impressions,
    SUM(clicks) AS clicks
  FROM
    sponsored_ads_traffic

    ad_product_type IN (

    'sponsored_brands')
