pandas不同数据库中的存储过程 - Sql server

Question

Running this code snippet works fine when typing the sql command directly into python.

cnxn = pyodbc.connect(driver and login details go here)
sql = """ sql command that produces a table from the main database """
df = pd.io.sql.read_sql_query(sql, cnxn)

However, the dataframe returns a 'TypeError: 'NoneType' object is not iterable', when I try to run the same code as a stored procedure.

sql = " Use database2 exec dbo.Open_Accounts "

I am also aware that you can't use the go command in pyodbc

USE [database2]
GO
EXEC    [dbo].[Open_Accounts]
GO

and thus can't use the SQL code directly.

Answer 1

EXEC Database2..Open_Accounts ?? --IF ANy Parameter There.
