Lire les données de pyodbc à pandas

J'interroge une base de données SQL et je veux utiliser pandas pour traiter les données. Cependant, je ne suis pas sûr de la manière de déplacer les données. Vous trouverez ci-dessous mon entrée et ma sortie.

import pyodbc
import pandas
from pandas import DataFrame

cnxn = pyodbc.connect(r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\users\bartogre\desktop\CorpRentalPivot1.accdb;UID="";PWD="";')
crsr = cnxn.cursor()
for table_name in crsr.tables(tableType='TABLE'):
    print(table_name)
cursor = cnxn.cursor()
sql = "Select sum(CYTM), sum(PYTM), BRAND From data Group By BRAND"
cursor.execute(sql)
for data in cursor.fetchall():
    print (data)

('C:\\users\\bartogre\\desktop\\CorpRentalPivot1.accdb', None, 'Data', 'TABLE', None)
('C:\\users\\bartogre\\desktop\\CorpRentalPivot1.accdb', None, 'SFDB', 'TABLE', None)
(Decimal('78071898.71'), Decimal('82192672.29'), 'A')
(Decimal('12120663.79'), Decimal('13278814.52'), 'B')

Une réponse plus courte et plus concise

import pyodbc
import pandas
cnxn = pyodbc.connect(r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};'
                      r'DBQ=C:\users\bartogre\desktop\data.mdb;')
sql = "Select sum(CYTM), sum(PYTM), BRAND From data Group By BRAND"
data = pandas.read_sql(sql,cnxn)

Une autre méthode plus rapide. Veuillez voir data = pd.read_sql (sql, cnxn)

import pyodbc
import pandas as pd
from pandas import DataFrame
from pandas.tools import plotting
from scipy import stats
import matplotlib.pyplot as plt
import seaborn as sns

cnxn = pyodbc.connect(r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=C:\users\bartogre\desktop\data.mdb;UID="";PWD="";')
crsr = cnxn.cursor()
for table_name in crsr.tables(tableType='TABLE'):
    print(table_name)
cursor = cnxn.cursor()
sql = "Select *"
sql = sql + " From data"
print(sql)
cursor.execute(sql)
data = pd.read_sql(sql, cnxn)

Je pensais bien celui-ci!

cnxn = pyodbc.connect(r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\users\bartogre\desktop\CorpRentalPivot1.accdb;UID="";PWD="";')
crsr = cnxn.cursor()
for table_name in crsr.tables(tableType='TABLE'):
    print(table_name)
cursor = cnxn.cursor()
sql = "Select sum(CYTM), sum(PYTM), BRAND From data Group By BRAND"
cursor.execute(sql)
data = cursor.fetchall()
print(data)
Data = pandas.DataFrame(data)
print(Data)
