我对以下代码有问题：

from pandasql import sqldf
import pandas as pd

df = pd.DataFrame({'column1': [1, 2, 3], 'column2': [4, 5, 6]})

query = "SELECT * FROM df WHERE column1 > 1"

new_dataframe = sqldf(query)

print(new_dataframe)

当我提交时，出现以下错误：

Traceback (most recent call last):

  File ~\AppData\Local\Programs\Spyder\Python\lib\site-packages\sqlalchemy\engine\base.py:1410 in execute
    meth = statement._execute_on_connection

AttributeError: 'str' object has no attribute '_execute_on_connection'


The above exception was the direct cause of the following exception:
