NoneType object is not iterable error in pandas

Question

I am trying to pull some data from a stored proc on a sql server using python.

Here is my code:

import datetime as dt
import pyodbc
import pandas as          


        

Answer 1

Your sproc needs

SET NOCOUNT ON;

Without this sql will return the rowcount for the call, which will come back without a column name, causing the NoneType error.

Answer 2

pd.read_sql() expects to have output to return, and tries to iterate through the output; that's where the TypeError is coming from. Instead, execute with a cursor object:

import datetime as dt
import pyodbc
import pandas as pd

conn = pyodbc.connect('Trusted_Connection=yes', driver = '{SQL Server Native client 11.0}',server = '*****', database = '**')
cur = conn.cursor()
cur.execute("EXEC ******** '20140528'")

You won't receive any output, but since none is expected, your code should run without error.

Answer 3

import datetime as dt
import pyodbc
import pandas as pd

conn = pyodbc.connect('Trusted_Connection=yes; driver =SQL Server Native client 
11.0; server = *****, database = **')
sqlSend = conn.cursor()
sqlSend.execute(f"EXEC ******** '20140528'")
conn.commint()
