bigquery: query data JSON

Question

I have an JSON objet withs ID / keys.

Within those keys is the result of each analysis of each ID.

"raw_result":{"3117092402546":true,"3110924118082":false,"3117014230082":true,"3171295576130":true}

I need to extract that information in some way that allows me to make queries later. For example: an array of data.

result I expected

**document_id     id                   result**
918348            3117092402546        true
918348            3110924118082        false    
918348            3117014230082        true
918348            3171295576130        true 

could you help me?

Try this one:

WITH sample AS (
  SELECT JSON_QUERY('{"raw_result":{"3117092402546":true,"3110924118082":false,"3117014230082":"true","3171295576130":true}}', '$.raw_result') json
)
SELECT k AS id, v AS result
  FROM sample,
       UNNEST(bqutil.fn.json_extract_keys(json)) k WITH OFFSET ki,
       UNNEST(bqutil.fn.json_extract_values(json)) v WITH OFFSET vi
 WHERE ki = vi
;

And for the UDFs I've used, you can check them on below site:
