Обсуждение: ODBC
Some of our users use an ODBC connection between MS Access and an Oracle database to work with the data.
Access however has a 255 field/column limit, which the Oracle Db has now execeded.
Is there a way to make an ODBC connection between a postgresql db and the oracle DB and pull all the data from the Oracle DB to the Postgresql DB?

I am not sure what kind of data model would require 255 columns, but if there is not in fact de-normalization occurring here and you really do need > 255 columns in your tables there is a way to make this work in access. You can create multiple bound table(sort of like a vertically partitioned view). In each bound table in access only include the primary key and a subset of the columns. Of Course this will probably complicate your application design. I don't believe that you can bind oracle table to postgresql. There is a module dbi-link that is similar to what you want to do.
