我最近在使用 Python API 时收到以下 BigQuery 错误：

google.api_core.exceptions.BadRequest：无法为脚本设置 400 configuration.query.destinationTable

这是我使用的功能：

def execute_bigquery_sql(query, dataset_id, table_id, use_legacy_sql=True, write_disposition='WRITE_TRUNCATE'):
    client = bigquery.Client()
    job_config = bigquery.QueryJobConfig()
    job_config.use_legacy_sql = use_legacy_sql

    print("table_id: {table_id}".format(table_id=table_id))
    print("dataset_id: {dataset_id}".format(dataset_id=dataset_id))

    if table_id:
        table_ref = client.dataset(dataset_id).table(table_id)
        print("table_ref: {table_ref}".format(table_ref=table_ref))
        job_config.destination = table_ref
        job_config.write_disposition = write_disposition
        job_config.allow_large_results = True
        job_config.createDisposition = "CREATE_IF_NEEDED"

    query_job = client.query(query,job_config=job_config)
    results = query_job.result()  # Waits for job to complete.

有谁知道可能会发生什么和解决方法？

如果我有

footnotes = { "apple" => "is a fruit", "cat" => "is an animal", "car" => "a transport"}

我如何得到这些的索引？,如:

footnotes["cat"].index
# => 1

如何在Ruby中求和

[1, 2, nil, 4] 

同

[nil, 2, nil, 4] 

并有

[1, 4, nil, 8]

？
