Question

The below code is working for me to create a table as below:

SELECT reviews.style_id, AVG("col1"), AVG("col2")
  FROM reviews, audios
 WHERE reviews.consumer_id = audios.consumer_id
 GROUP BY style_id

So my issue is that I would like to average col1 and col2, not worrying about NULL values, as they won’t exist in my table. However, I do need to maintain the logic of the join. Thanks!

Answer 1

Is this what you want?

SELECT reviews.style_id,
       (AVG("col1") + AVG("col2")) / 2.0
FROM reviews, audios
WHERE reviews.consumer_id = audios.consumer_id
GROUP BY style_id
