'QueryResults' 对象没有属性 'result'

Question

from google.cloud import bigquery
import datalab.bigquery as bq

query_job = client.run_sync_query("""
    SELECT
      CONCAT(
        'https://stackoverflow.com/questions/',
        CAST(id as STRING)) as url,
       view_count
    FROM `bigquery-public-data.stackoverflow.posts_questions`
    WHERE tags like '%google-bigquery%'
ORDER BY view_count DESC
LIMIT 10""")

results = query_job.result()  # Waits for job to complete.

for row in results:
    print("{}".format(row.start_time))

我尝试在 jupyter notebook 中运行以上代码，但系统给出“AttributeError: 'QueryResults' object has no attribute 'result'”

我找不到替换结果对象的文档。

（现有文档 https://cloud.google.com/bigquery/create-simple-app-api 已过时，因为 run_sync_query 也正在替换 run_query） 你能帮帮我吗？

我使用您提供的第二个示例进行了一些更改以适应它，它对我有用。代码：

from google.cloud import bigquery


client = bigquery.Client()

QUERY = ("""
    SELECT
      CONCAT(
        'https://stackoverflow.com/questions/',
        CAST(id as STRING)) as url,
       view_count
    FROM `bigquery-public-data.stackoverflow.posts_questions`
    WHERE tags like '%google-bigquery%'
ORDER BY view_count DESC
LIMIT 10""")
query_job = client.query(QUERY)

iterator = query_job.result()
rows = list(iterator)

for row in rows:
    print row

然后输出：

Row((u'https://stackoverflow.com/questions/13530967', 42898), {u'url': 0, u'view_count': 1})
Row((u'https://stackoverflow.com/questions/13221978', 30824), {u'url': 0, u'view_count': 1})
Row((u'https://stackoverflow.com/questions/6607552', 24524), {u'url': 0, u'view_count': 1})
