'How do I read SQL stored procedure data through pyodbc and get results into a dataframe?
I have a stored proc in SQL Server called test.storedproc
My py script is as follows
import pyodbc
import pandas as pd
conn = pyodbc.connect('Driver={SQL Server};'
'Server=PMI0x8x\xxx;'
'Database=Warehouse;'
'Trusted_Connection=yes;'
)
cmd_prod_executesp = """EXEC Test.storedproc"""
cursor = conn.cursor()
cursor.execute(cmd_prod_executesp)
conn.commit()
This runs successfully. However, how do I get the data which is in the storedproc as a dataframe?I tried -
dfo = pd.read_sql_query(cmd_prod_executesp, conn)
Traceback (most recent call last):
File "<ipython-input-70-06220d2e8e81>", line 1, in <module>
dfo = pd.read_sql_query(cmd_prod_executesp, conn)

columns = [col_desc[0] for col_desc in cursor.description]
TypeError: 'NoneType' object is not iterable
How do I read stored proc data into a dfo?

Not enough rep to comment or I would (since this isn't an explicit answer) but you could use the sp to run the data into a temp table then select * from temp table and then the df = pd.read_sql(sql, con=connection) should work just fine.
If you aren't as handy with sql... here is a topic which shows how to run sp into temp table. link
