Get Async Query Results
Returns the results of an async query task if the query has completed.
If the query task is still running or waiting to run, this function returns 204 No Content.
If the query task ID is invalid or the cached results of the query task have expired, this function returns 404 Not Found.
Use query_task(query_task_id) to check the execution status of the query task Call query_task_results only after the query task status reaches "Complete".
You can also use query_task_multi_results() retrieve the results of multiple async query tasks at the same time.
SQL Error Handling:
If the query fails due to a SQL db error, how this is communicated depends on the result_format you requested in create_query_task()
.
For json_detail
result_format: query_task_results()
will respond with HTTP status '200 OK' and db SQL error info
will be in the errors
property of the response object. The 'data' property will be empty.
For all other result formats: query_task_results()
will respond with HTTP status 400 Bad Request
and some db SQL error info
will be in the message of the 400 error response, but not as detailed as expressed in json_detail.errors
.
These data formats can only carry row data, and error info is not row data.

Response
200: The query results.

404: The Query Task Id was not found or the results have expired.
