标签: read-sql

我尝试使用 sqlalchemy 引擎直接从 sqlserver 数据库创建 pandas DataFrame：

engine = create_engine(URL_string, echo=False, future=True)
query_string = "..."
dt = pd.read_sql(query_string, engine)

但这会引发此错误：

File <redacted>/venv/lib/python3.8/site-packages/sqlalchemy/future/engine.py:320, in Engine._not_implemented(self, *arg, **kw)
    319 def _not_implemented(self, *arg, **kw):
--> 320     raise NotImplementedError(
    321         "This method is not implemented for SQLAlchemy 2.0."
    322     )

NotImplementedError: This method is not implemented for SQLAlchemy 2.0.

我这样做是因为单独使用 pyodbc 的连接会发出警告：
