Since SqlAlchemy is database-agnostic, you should be able to grab the info from Access, connect to another database with a pre-created matched db schema and just tell SqlAlchemy to put the data into it. For the most part, it can translate db differences such that this will work without any (or few) issues. Note that SqlAlchemy's support of Access is experimental.

Open the Postgres database using adodbapi. I have already done all of the tricky COM stuff for you. You can also open the ACCESS database using adodbapi. There is an example in C:\python{your version number here}\Lib\site-packages\adodbapi\tests\db_print.py . Given that your databases are so completly different, you will most likely need to copy the data field-by-field. I think you will find no pre-packaged move-this-whole-table shortcut for this job. If the Postgres will not work for you, please let me know. I am planning to add Postgres tests and examples to the adodbapi test suite, and have set up a test server, but have not made the time to get further. We could work together on Postgres support. By the way, I disagree with Gerdus. I personally find Python much easier to use than VBA for prototyping and quickie jobs. -- Vernon Cole On Wed, Jul 29, 2009 at 6:16 AM, Gerdus van Zyl wrote: > Are you trying to copy a table from an access database to a postgres > database?

Can you please help? This is obviously tricky with two different databases in the equation, one of them PostgreSQL, but what will be most helpful is for you to produce an easily reproducible sample which someone else can run, plus the traceback you get. Going through this exercise may even cause you to track down the problem yourself. In particular, try to eliminate external dependencies: try to do the copy table thing between two Access databases, or within the same one (if that's possible; I haven't used Access in earnest for a while now).

I'm placing that dataset into a dictionary -- works. I'm placing that dictionary into a list -- problem!! When I move to the next record in the dataset and place the dictionary created from that into the list all the members that are in the list change to that record. here is that portion of the code: prv640_records = [] while not rtn.EOF: prv640_dict['promise_id'] = rtn.Fields.Item('promise_id').Value prv640_dict['service_location'] = rtn.Fields.Item('service_location').Value prv640_dict['mco_code'] = rtn.Fields.Item('subnetwork_id').Value prv640_dict['begin_date'] = rtn.Fields.Item('begin_date').Value prv640_dict['end_date'] = rtn.Fields.Item('end_date').Value prv640_dict['mco_prov_number'] = rtn.Fields.Item('provider_id').Value prv640_dict['action'] = rtn.Fields.Item('STATUS').Value rtn.MoveNext() prv640_records.append(prv640_dict) So the first time through the while loop, prv640_records will contain one dictionary that is the first record in rtn. The second time through the loop prv640_records will contain 2 dictionaries that are both the 2nd record in rtn. The first dictionary in prv640_records is somehow replaced. So in testing this with a record set of 402 records, at the end of the while loop, the list prv640_records will contain 402 dictionaries that are all the last record of rtn. I hope this is a clear explanation of the problem. Does anyone have an idea why? I been trying to figure this out for 3 hours now.

You appear to be re-using the same dictionary for each record; allocate a new one for each record before starting to populate it. -------------------------> "These thoughts are mine alone!" <--------- Andrew MacIntyre National Licensing and Allocations Branch tel: +61 2 6219 5356 Inputs to Industry Division fax: +61 2 6253 3277 Australian Communications & Media Authority email: andrew.macintyre at acma.gov.au http://www.acma.gov.au/ If you have received this email in error, please notify the sender immediately and erase all copies of the email and any attachments to it.

When I move to the next record in the dataset and place the dictionary created from that into the list all the members that are in the list change to that record. Not really a pywin32 related by I will bite :) For every iteration of the while loop you have to create a new dictionary, fill it up with data and append to the list. > > here is that portion of the code: > > ? ?prv640_records = [] > ? ?while not rtn.EOF: prv640_dic = {} > ? ? ?prv640_dict['promise_id'] = rtn.Fields.Item('promise_id').Value > ? ? ?prv640_dict['service_location'] = rtn.Fields.Item('service_location').Value > ? ? ?prv640_dict['mco_code'] = rtn.Fields.Item('subnetwork_id').Value > ? ? ?prv640_dict['begin_date'] = rtn.Fields.Item('begin_date').Value > ? ? ?prv640_dict['end_date'] = rtn.Fields.Item('end_date').Value > ? ? ?prv640_dict['mco_prov_number'] = rtn.Fields.Item('provider_id').Value > ? ? ?prv640_dict['action'] = rtn.Fields.Item('STATUS').Value > > ? ? ?rtn.MoveNext() > ? ? ?prv640_records.append(prv640_dict) > > So the first time through the while loop, prv640_records will contain one dictionary that is the first record in rtn.

In a debugger type >>> id(prv640_records[0]), d(prv640_records[1]) It will display two identical identifiers. Also I would recommend using adodbapi or pyodbc module for talking to SQL Server. adodbapi is already included in pywin32 distribution. The API of both those extensions follow DBAPI 2 http://www.python.org/dev/peps/pep-0249/ Much nicer IMHO.

I posted here because this has never happened to me before, only with the COM object thrown in does it do this. So I assumed it was some kind of windows COM issue. >> >> here is that portion of the code: >> >> prv640_records = [] >> while not rtn.EOF: >> prv640_dic = {} >> prv640_dict['promise_id'] = rtn.Fields.Item('promise_id').Value >> prv640_dict['service_location'] = rtn.Fields.Item('service_location').Value >> prv640_dict['mco_code'] = rtn.Fields.Item('subnetwork_id').Value >> prv640_dict['begin_date'] = rtn.Fields.Item('begin_date').Value >> prv640_dict['end_date'] = rtn.Fields.Item('end_date').Value >> prv640_dict['mco_prov_number'] = rtn.Fields.Item('provider_id').Value >> prv640_dict['action'] = rtn.Fields.Item('STATUS').Value >> >> rtn.MoveNext() >> prv640_records.append(prv640_dict) >> I made this work by adding prv640_dict = None after the list append. >It really is the same dictionary referenced 402 times. >In a debugger type >>> id(prv640_records[0]), d(prv640_records[1]) >It will display two identical identifiers.

I looked at this a few years ago but for me it was easier to use COM with stored procedures, but I will look at it again. Thanks Rod Waldemar
