Обсуждение: synchronizing MS access and postgresql tables
We have a number of tables in a CRM that is written in MS access that I need to be able to provide a web interface to. I can export the tables just fine using pgadmin II, but I cant' think of a clean way to import them from postgresql back to access. Synchronizing only needs to happen once a day at the most. I was also thinking of using the MS access forms with access tables that are just odbc links to the postgresql database. Does anyone know off hand if changing the MS access tables from a native table to a linked table would require changes in the forms (not counting having to tweak/change data types) ?

This does work, we have done it. However you will want to over time move a lot of the stored queries etc... to PostgreSQL versus Access for performance reasons. Sincerely, Joshua D.

I don't think so. Michael -- Michael Meskes Email: Michael at Fam-Meskes dot De ICQ: 179140304, AIM/Yahoo: michaelmeskes, Jabber: meskes@jabber.org Go SF 49ers! Go Rhein Fire! Use Debian GNU/Linux!

The big gotcha on linked tables in Access is that Access will "Background fetch" the entire table of any objects that referencethat table on an open form. They try to throttle it so you won't notice, but you might. Also, if you have Access queries that reference linked tables, Access will fetch the entire contents of all referenced tablesbefore performing any joins/restrictions. That can really suck. Another poster alluded to this when they suggested moving objects into Postgresql. Things like views. It works fine, generally. Expect lots of harmless errors in your logs about how it can't find a certain system table, andhow it keeps hanging up on Postgresql without closing the connection nicely. >>> "Chris Ochs" <chris@paymentonline.com> 04/30/04 09:29AM >>> We have a number of tables in a CRM that is written in MS access that I need to be able to provide a web interface to.
