Consider the following snippet of code: import win32com.client
DSN = 'PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=M:\\Finance\\camel\ \camel.mdb;' conn.Open(DSN) cursor = conn.Execute("UPDATE tblInvoice SET InvComments='Python' WHERE InvBillingPeriod = 'April 2010' AND InvJobCode = '2169'") rows = cursor.Affected_Rows() print rows conn.Close() I am using Python 2.6.5, and pywin32. If I try to run it, I get the response: Traceback (most recent call last): File "C:/Users/mcarter/tacc/pypms/post.py", line 79, in <module> AdjustPms(d) File "C:/Users/mcarter/tacc/pypms/post.py", line 64, in AdjustPms cursor = conn.Execute("UPDATE tblInvoice SET InvComments='Python' WHERE InvBillingPeriod = 'April 2010' AND InvJobCode = '2169'") File "<COMObject ADODB.Connection>", line 3, in Execute File "C:\Python26\lib\site-packages\win32com\client\dynamic.py", line 272, in _ApplyTypes_ result = self._oleobj_.InvokeTypes(*(dispid, LCID, wFlags, retType, argTypes) + args) pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'Microsoft JET Database Engine', u"Cannot open database ''. It may not be a database that your application recognizes, or the file may be corrupt.", None, 5003049, -2147467259), None) I have used the same DNS to retrieve data from the database using SELECT statements, so I'm at a loss to figure out what's going wrong. It seems to think the database name as an empty string. I'm not sure if that's the root cause of the problem, though. Any ideas? -- http://mail.python.org/mailman/listinfo/python-list
