Pyathena 设置默认数据库？

Question

from pyathena import connect
import pandas as pd

conn = connect(aws_access_key_id='YOUR_ACCESS_KEY_ID',
             aws_secret_access_key='YOUR_SECRET_ACCESS_KEY',
             s3_staging_dir='s3://YOUR_S3_BUCKET/path/to/',
             region_name='us-west-2')
res = pd.read_sql("select * from db_name.tablename",conn)

如何在连接框架本身中指定数据库名称，或者是否有任何解决方法？

Answer 1

您可以将schema_name作为参数添加到connect() 。 默认值为schema_name='default'

例如：

conn = connect(aws_access_key_id='YOUR_ACCESS_KEY_ID',
             schema_name='my_schema',
             aws_secret_access_key='YOUR_SECRET_ACCESS_KEY',
             s3_staging_dir='s3://YOUR_S3_BUCKET/path/to/',
             region_name='us-west-2')
