我正在尝试使用 databricks 最新版本（7.1+，spark 3.0）与 pyspark 作为脚本编辑器/基本语言连接 bigquery。完成此操作的步骤：
- 将 bigquery API 传递给数据块进行连接
- 在 databricks 中安装了 Spark bigquery 最新的 jar 我们运行了下面的 pyspark 脚本来从 bigquery 表中获取数据到 databricks
from pyspark.sql import SparkSession
spark = (
SparkSession.builder
.appName('bq')
.master('local[4]')
.config('parentProject', 'google-project-ID')
.config('spark.jars', 'jarlocation.jar') \
.getOrCreate()
)
df = spark.read.format("bigquery").option("credentialsFile", "file path") \
.option("parentProject", "google-project-ID") \
.option("project", "Dataset-Name") \
.option("table","dataset.schema.tablename*") \
.load()
运行脚本后，当我们尝试查看数据时，出现以下错误。
错误：

但是，如果我们尝试在表名中不提供“*”的情况下获取数据，我们就能够以嵌套格式获取数据。有没有办法在单个脚本中获取单个模式下的所有表？
帮助将不胜感激。提前致谢！
