The Jet drivers (32 bit only) which can be used from ODBC have been supplied with every MS OS (even 64 bit ones). I've used this driver and ODBC to access .mdb files without Office or Access ever having been near machines. To see the drivers on your machine run up odbcad32.exe and check the drivers tab. To see 32 bit drivers on a 64 bit machine run Windows\SysWOW64\odbcad32.exe There is no 64 bit Jet driver, but from Office 2007 on, MS produced the ACE drivers (which are also available as a separate redistributable) which do appear in a 64 bit guise. Unfortunately I haven't been impressed with the drivers stability when multithreading. -- Regards, Graham Bloice ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

Gary: I was able to track down a Windows 7 - 64 bit computer this morning. Installed Python 3.1 (32 bit) Installed pywin32-214 for py31 (32 bit) Installed adodbapi 2.4 (to get the test.mdb database) I was able to read the data correctly. No Microsoft office components were installed. (I also found an error in my db_read.py sample program when run from Python 3, so this was a good test.) -- Vernon ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

Re: [python-win32] odbc under windows 7?
I think Tim's last suggestion is the way to go, and you should NOT need
ACCESS installed.
Microsoft invented ODBC.
Everybody saw it was a great idea and adopted it.
So Microsoft had to invent something even newer, which everybody else does
not support. That's called ADO. ADO defaults to ODBC mode, so usually you
can happily forget it is there, and use ODBC drivers for everything. But in
native ADO mode, you don't use *drivers*, you use *providers*, (along with a
connection string which is completely different from odbc.)
The provider for Access-type data bases is called JET. It should be
included on any NT-based Windows version. ACCESS is not required.
The setup I use for testing ado's ability to read and write an ACCESS .mdb
file is something like this:
Python
import adodbapi
_databasename = Test.mdb
constr = 'Provider=Microsoft.Jet.OLEDB.4.0; Data Source=%s' % _databasename
_table_name= 'Products'
#create the connection
con = adodbapi.connect(constr)
#make a cursor on the connection
c = con.cursor()
#run an SQL statement on the cursor
sql = 'select * from %s' % _table_name
c.execute(sql)
#get the results
db = c.fetchmany(5)
#print them
for rec in db:
print rec
print
print 'repr() of next row is...'
print repr(c.next())
print
c.close()
con.close()
/Python
Running the script (on my 32-bit Vista laptop with no Microsoft Office
components installed) gives:
console dump
('1', 'Widgit', '5.0', '15.1234', '2009-01-29 13:05:30')
('2', 'Thingamajig, Standard', '505.0', '0.1', '2009-01-29 15:05:19')
('3', 'Left Handed Smoke Shifter', '1.0', '100', '2008-04-01 12:00:00')
('4', 'Gravel (Bulk)', '100.25', '32.4567', '2009-01-29 13:05:31')
('5', 'Tube, Drinking, Plastic, For cold liquids', '50.0', '0.0013',
'2009-01-29 13:05:32')
repr() of next row is...
SQLrow={ItemNumber:6, ItemName:u'Annoy-A-Tron', UnitsOnHand:1.0,
CostPerUnit:Decimal('12.95'), LastOrdered:datetime.datetime(2009, 1, 29, 13,
5, 33)}
/console dump
---
Notes:
* Test.mdb is in the /test folder of the adodbapi source distribution.
* to get that fancy row object with the column names, you must be running
the latest version of adodbapi from
http://sourceforge.net/projects/adodbapi/. The version which ships with
pywin32 at will just give a normal tuple -- until the next release of
pywin32.
* I could not locate a 64 bit Windows 7 box to test this on. I tried.
Sorry. Please report back whether or not this works for you.
