How can I best flatten a table with a JSON_EXTRACT_ARRAY query that flattens the below table?
I tried:
with raw as (
select *
from {{ source('hubspot','deal_pipelines') }}
temp as (
select JSON_EXTRACT_ARRAY(stages,'$') as stages
from raw
select
json_value(s,'$.label') as label
,json_value(s,'$.active') as active
from temp ,unnest(stages) as s
But I get this error:
No matching signature for function JSON_EXTRACT_ARRAY for argument types: ARRAY<STRUCT<value STRUCT<probability FLOAT64, displayorder INT64, active BOOL, ...>>>, STRING. Supported signatures: JSON_EXTRACT_ARRAY(STRING, [STRING]); JSON_EXTRACT_ARRAY(JSON, [STRING]) at [18:8]
Any suggestions how to fix it are greatly appreciated.
stages
has a type of ARRAY<STRUCT<value STRUCT<probability FLOAT64, displayorder INT64, active BOOL, ...>>>
, not a JSON string. So you seem to want below.
with raw as (
select *
from {{ source('hubspot','deal_pipelines') }}
select
s.value.label as label,
s.value.active as active
from raw, unnest(stages) as s;
