Connection error to Access database

问题

I wrote the program which by means of pyodbc is connected to Access to that it was very glad. Help me please.

import pyodbc
#import kinterbasdb
import firebirdsql
import os, sys
import json,sqlite3,sql
sys.version_info
s1='''
create table CLIENTS
    (
       ID    INTEGER NOT NULL,
       COMPANY   VARCHAR(50),
       "LAST NAME"   VARCHAR(50),
       "FIRST NAME"   VARCHAR(50),
       "E-MAIL ADDRESS"   VARCHAR(50),
       "JOB TITLE"   VARCHAR(50),
       "BUSINESS PHONE"   VARCHAR(25),
       "HOME PHONE"   VARCHAR(25),
       "MOBILE PHONE"   VARCHAR(25),
       "FAX NUMBER"   VARCHAR(25),
       ADDRESS   BLOB SUB_TYPE 1,
       CITY   VARCHAR(50),
       "STATE/PROVINCE"   VARCHAR(50),
       "ZIP/POSTAL CODE"   VARCHAR(15),
       "COUNTRY/REGION"   VARCHAR(50),
       "WEB-SITE"   VARCHAR(25),
       NOTES   BLOB SUB_TYPE 1,
       INCLUDING   BLOB,
       CONSTRAINT PK_CLIENTS_ID PRIMARY KEY(ID)
    );
'''
s2='''create ascending index IDX_CLIENTS_CITY on CLIENTS (CITY);'''
#os.remove('D:/ThirdTask/test1.fdb')
conn=firebirdsql.create_database(host='localhost', database='/test1.fdb', user='sysdba', password='masterkey')
#con=firebirdsql.connect(host='localhost',database='D:/ThirdTask/test1.fdb', user='sysdba', password='masterkey')
cur=conn.cursor()
cur.execute(s1)
#cur.execute(s2)
conn.commit()
conAcc = pyodbc.connect('DRIVER={Microsoft Access Driver (*.accdb)};DBQ=Northwind.accdb')
conn.close()

As a result I received an error that me very much baffled. Help me please. I don't know in what a cause of error

Traceback (most recent call last):
  File "D:\ThirdTask\connecttwo.py", line 39, in <module>
    conAcc = pyodbc.connect('DRIVER={Microsoft Access Driver (*.accdb)};DBQ=Northwind.accdb')

回答1:

The driver name you specified...

DRIVER={Microsoft Access Driver (*.accdb)}

...is incorrect. There is no ODBC driver with that name. 32-bit applications that want to open an older .mdb database file can use

Driver={Microsoft Access Driver (*.mdb)}

To open an .mdb file from a 64-bit application, or to open an .accdb file from any application, you need to use

Driver={Microsoft Access Driver (*.mdb, *.accdb)}

回答2:

It looks like you do not have connected to the DB. Maybe you should begin with a smaller program just to connect. Samples in other questions : Using Microsoft Access SQL operators in Python ODBC

This might help.

import pyodbc

# Connect to your access database file

DBfile = 'Filename.mdb'  # Let your file name <Filename> and access extension .mdb
conn = pyodbc.connect('DRIVER={Microsoft Access Driver (*.mdb)};DBQ='+DBfile)  #    user/password can be used
cur = conn.cursor()

# Create new table in database

cur.execute ('CREATE TABLE CLIENTS (ID INTEGER, COMPANY STRING)')
conn.commit()

cur.close()
conn.close()
