Be sure to check out the FAQs and How-tos at the psqlodbc project site:
http://gborg.postgresql.org/project/psqlodbc/projdisplay.php

You will find that that Access and PostgreSQL get on well together.  You can
get by with the default driver settings for the most part; I suggest that
you make sure that the "row versioning" and "true = -1" options are set to
true.  If you want to use the "memo" datatype in Access, then you will need
to check "text = longvarchar" option.

If you have further questions, try posting to the pgsql-odbc list.

Subject: [GENERAL] psqlodbc MSAccess and Postgresql

Thanks for the help with /dt... Mike, your post helped me to discover psql command window, I had been trying out the pgAdmin ...  

 

I found an interesting article regarding MSAccess as a front end to Postgresql, so I downloaded the psqlodbc installer.  I will be getting up the nerve to run the install and go into windows odbc and install that driver so I can use MSAccess with Postgresql ... any tips or caveats appreciated....

 

This is the link which is guiding me....

This doesn't really make sense. It sounds like you want a key that is unique
accross the union of several tables and that doesn't change when other rows
in the union are added or removed. There are a couple of ways you might
go about doing something like this. Is this what you really want?

I don't know MS Access, so I am not going to be able to help much with this.
There may be some way to trick MS Access into thinking that your view has
a unique numeric field. It would help to know how it knows that a column
has those properties and how it uses the information.

You can tell Access to use any combination of fields as a primary key, when
linking to the view.  There must be some unique combination that will work
as a key.  But this is really of no significance unless you want to issue
inserts or updates against the view, which raises another set of issues.
