Hello,
I came across a post from Nikhil Joshi at https://mail.python.org/pipermail/python-list/2014-November/681568.html. *.sdf database access - mail.python.org<https://mail.python.org/pipermail/python-list/2014-November/681568.html> mail.python.org On Saturday, April 21, 2012 6:55:55 AM UTC-4, Alex Willmer wrote: > On Apr 19, 9:18 pm, Page3D wrote: > > Hi, I am trying to connect and access ... I am facing the following problem. Can anyone please provide some guideline? Problem Statement: Extract data stored in the .sdf file to python. System config: Win 10 Pro 64-bit, python 3.5.2-64 bit, adodbapi library, SQL CE 3.5 I am fairly new to programming and I have picked up Python as my first language to learn. Currently, I have hit a wall in process of connecting a SQL CE 3.5 .sdf file. I have used the adodbapi library. I have searched the web extensively over the past week to find a solution to this problem and to make sure that my connection string is correct. I have tried multiple options/solutions provided on stack overflow and https://www.connectionstrings.com/microsoft-sqlserver-ce-oledb-3-5/. Code: import adodbapi cons_str = "Provoider=Microsoft.SQLSERVER.MOBILE.OLEDB.3.5;" \ "Data Source=D:\Work\Programming\Python\SQL_DataTransfer\LF.sdf;"\ "Persist Security Info=False;" \ "SSCE:Max Database Size=4091" connection = adodbapi.connect(cons_str) print(connection) Error Message: Traceback (most recent call last): File "D:\Work\Programs\Python35.virtualenvs\sql_output\lib\site-packages\adodbapi\adodbapi.py", line 93, in make_COM_connecter c = Dispatch('ADODB.Connection') #connect after CoIninialize v2.1.1 adamvan NameError: name 'Dispatch' is not defined During handling of the above exception, another exception occurred: Traceback (most recent call last): File "D:\Work\Programs\Python35.virtualenvs\sql_output\lib\site-packages\adodbapi\adodbapi.py", line 112, in connect co.connect(kwargs) File "D:\Work\Programs\Python35.virtualenvs\sql_output\lib\site-packages\adodbapi\adodbapi.py", line 269, in connect self.connector = connection_maker() File "D:\Work\Programs\Python35.virtualenvs\sql_output\lib\site-packages\adodbapi\adodbapi.py", line 95, in make_COM_connecter raise api.InterfaceError ("Windows COM Error: Dispatch('ADODB.Connection') failed.") adodbapi.apibase.InterfaceError: Windows COM Error: Dispatch('ADODB.Connection') failed.
