无法使用 python adodbapi 库建立数据库连接

Question

我正在尝试使用 python 库 adodbapi 和 latest OLEDB 提供程序建立 SQL 服务器数据库连接，使用以下代码-

import adodbapi
import configparser

def try_connection():    
    _SERVER_NAME = "SERVERNAME"
    _DATABASE = "TESTDB"
    _USERNAME = "TERSTUSER"
    _PASSWORD = "TESTPWD"  

    conn = adodbapi.connect("PROVIDER=MSOLEDBSQL;Data Source={0};Database={1};UID={2};PWD={3};".format(_SERVER_NAME,_DATABASE,_USERNAME,_PASSWORD))
    cursor = conn.cursor()

print( try_connection() )

但是，我无法建立连接。我遇到了无法弄清楚的巨大跟踪错误：

Traceback (most recent call last):
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\adodbapi\adodbapi.py", line 97, 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 "C:\Program Files (x86)\Python 3.5\lib\site-packages\adodbapi\adodbapi.py", line 116, in connect
    co.connect(kwargs)
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\adodbapi\adodbapi.py", line 266, in connect
    self.connector = connection_maker()
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\adodbapi\adodbapi.py", line 99, in make_COM_connecter
    raise api.InterfaceError ("Windows COM Error: Dispatch('ADODB.Connection') failed.")
adodbapi.apibase.InterfaceError: Windows COM Error: Dispatch('ADODB.Connection') failed.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "TestAdodb.py", line 41, in <module>
    print( try_connection() )
  File "TestAdodb.py", line 18, in try_connection
    conn = adodbapi.connect("PROVIDER=MSOLEDBSQL;Data Source={0};Database={1};UID={2};PWD={3};".format(_SERVER_NAME,_DATABASE,_USERNAME,_PASSWORD))
  File "C:\Program Files (x86)\Python 3.5\lib\site-packages\adodbapi\adodbapi.py", line 120, in connect
    raise api.OperationalError(e, message)
adodbapi.apibase.OperationalError: (InterfaceError("Windows COM Error: Dispatch('ADODB.Connection') failed.",), 'Error opening connection to "PROVIDER=MSOLEDBSQL;Data Source=SERVERNAME;Database=TESTDB;UID=TERSTUSER;PWD=TESTPWD;"')

谁能告诉我连接字符串中的 wrong/missing 是什么？

Answer 1

引用自pypi,

Prerequisites:

C Python 2.7 or 3.5 or higher and pywin32 (Mark Hammond's python for windows extensions.) or Iron Python 2.7 or higher. (works in IPy2.0 for all data types except BUFFER)

Installation:

(C-Python on Windows): Install pywin32 ("pip install pywin32") which includes adodbapi.

(IronPython on Windows): Download adodbapi from http://sf.net/projects/adodbapi. Unpack the zip. Open a command window as an administrator. CD to the folder containing the unzipped files. Run "setup.py install" using the IronPython of your choice.

您是否安装了 adodbapi 库的所有先决条件？

如果我没有安装 pywin32 库，我能够重现错误。

使用以下命令安装 pywin32 库：

pip install pywin32
