Question

我正在运行Win 7 32位并使用python 27，我尝试使用pyodbc在我的QGIS插件中连接ms-access数据库，但是当我启动它时出现以下错误：

 Traceback (most recent call last):
      File "C:/PROGRA~1/QGISDU~1/apps/qgis/./python\qgis\utils.py", line 204, in startPlugin
        plugins[packageName] = package.classFactory(iface)

错误：（'HY024'，“[HY024] [Microsoft] [ODBC Microsoft Access驱动程序]'（未知）'不是有效路径。请确保路径名拼写正确并且您已连接到文件所在的服务器。（-1023）（SQLDriverConnect）; [HY024] [Microsoft] [ODBC Microsoft Access驱动程序]'（未知）'不是有效路径。请确保路径名拼写正确，并且您连接到文件所在的服务器。（-1023）“）

我把它放在我的代码中：

from PyQt4 import QtCore, QtGui
from ui_testdbase import Ui_TestDbase
import pyodbc
db = pyodbc.connect(
        r'DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};' +
        r'DBQ=C:\__tmp\test1.accdb')

class TestDbaseDialog(QtGui.QDialog):
    def __init__(self):
        QtGui.QDialog.__init__(self)
        # Set up the user interface from Designer.
        self.ui = Ui_TestDbase()
        self.ui.setupUi(self)

        Rec_1 = self.ui.btnOke
        QtCore.QObject.connect(Rec_1, QtCore.SIGNAL('clicked()'),self.Compskala)


    def Compskala(self):
        skal1 = self.ui.lineSkal1.text()
        skal2 = self.ui.lineSkal2.text()
        bandskal = ''
        if skal1 == skal2:
            bandskal = 'Kedua Peta dapat dipadukan'

我真的是个新手，有人可以给我一个帮助吗？

在文件名中用反斜杠替换正斜杠似乎有效：

<强>失败

>>> db = pyodbc.connect("DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};" +
                        "DBQ=C:\__tmp\test.accdb")

Traceback（最近一次调用最后一次）：文件“”，第1行，in pyodbc.Error：（'HY000'，'[HY000] [Microsoft] [ODBC Microsoft Access Driver]不是有效的文件名。（-1044）（SQLDriverConnect）'）

<强>则成功

>>> db = pyodbc.connect("DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};" +
                        "DBQ=C:/__tmp/test.accdb")
>>> connection.getinfo(pyodbc.SQL_SERVER_NAME)
'ACCESS'

无法使用pyodbc连接QGIS插件和访问2007数据库
