Code Sample, a copy-pastable example
# Your code here
from sqlalchemy import create_engine, Table, Column, Integer, String
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
import pandas as pd
import sqlalchemy as sa
BaseModel = declarative_base()
class Test(BaseModel):
__tablename__ = "test"
id = Column(Integer, primary_key=True)
foo = Column(String(50))
engine = create_engine("sqlite:///")
BaseModel.metadata.create_all(engine)
Session = sessionmaker(bind=engine)
session = Session()
df = pd.DataFrame({"id": [0, 1], "foo": ["hello", "world"]})
df.to_sql("test", con=engine, index=False, if_exists="replace")
session.commit()
foo = session.query(Test.id, Test.foo)
df = pd.DataFrame(foo)
session.close()
print(df)
assert list(df.columns) == ["id", "foo"]
Problem description
Coping from sqlalchemy/sqlalchemy#6154.
In sqlalchemy 1.4 Query
returns Row
objects that are no longer subclass of tuple, so they don't pass the is_named_tuple
check, as mentioned by Mike here sqlalchemy/sqlalchemy#6154 (comment)
Expected Output
The colums are named 0,1
instead of 'id', 'foo'
Output of pd.show_versions()
