Connecting With a Dialect URL
Establishing a connection using SQLAlchemy requires a specific URL format.from sqlalchemy import create_engine
engine = create_engine("googlebigquery:///?InitiateOAuth=GETANDREFRESH;ProjectId=NameOfProject;DatasetId=NameOfDataset;")
For SQLAlchemy 2.0, the dialect name is googlebigquery_2. To establish a connection, use the following URL format:
from sqlalchemy import create_engine
engine = create_engine("googlebigquery_2:///?InitiateOAuth=GETANDREFRESH;ProjectId=NameOfProject;DatasetId=NameOfDataset;")
