Sql Create Nested Json In Snowflake Stack Overflow I want to create a nested json string where one phone number returns all product name in one row only. i have tried but the output of to json string isn't what i need. here is the image of the query result image. here the query that i used: to json string(struct( line.product name. )) as attributes. Bigquery offers a range of functions to tackle json: json query(json expression, json path): extracts a json value (object or array) as a json string. more efficient for nested structures .
Sql Create Nested Json In Snowflake Stack Overflow Storing json in bigquery when it comes to storing json data in bigquery, there are two options: use string type or create a struct. in this post, we will discuss the pros and cons of each option and how to query nested fields in bigquery. This guide embarks on a journey to illustrate the creation of nested json strings in bigquery, spotlighting the string agg() function, and delving into array agg() for constructing array like structures. I have a column in a bigquery table known as change json string, which contains two sets of values that i need to extract. given below is a sample record from said column: {"old value": {. ) from unnest( json extract array(data, '$.tasks.category business') ) business tasks ) as items from `table` ) this extracts just the information in the category business. what i'm trying to do is expand category community and any other children underneath the tasks key. the real data has at least 10 categories and 50 tasks.

Not general solution like @mikhail's answer but with some assumption you can also use a regular expression to extract most nested fields. select '{"field": {"properties": {"custom name": {"type":"string", "label":"custom name"}}}}' as json. trim(split(kv, ':')[offset(1)], '"') as value. From sample table, unnest(flatten json(json)) flattened; query results. i have a table with a column filled with stringified json so i have a json with an example as such: { "id 1": { "age": "10", "size": &quo. The following query properly nests contactaddress as an array under the outer json object: select [name], [id], . (isnull(( select [address1], [contactid] from [contactaddress] where [contactaddress].[contactid] = [contact].[id] for json path, include null values. ), json query('[]'))) [address] . from [contact] . Use this colab notebook (bigquery, json, structs, arrays, nested, repeated observations) to follow along with the rest of this post. given our source is json, we can create a basic bigquery table that stores the raw json as a single string column.
