Automatically Update Linked Tables

Automatically Update Linked Tables

Automatically Update Linked Tables

(OP)
I'm trying to set up an automated procedure that runs a Crystal report against an Access database.  The tables in Access are ODBC linked to an AS400 database.  I need the linked tables to refresh when Access opens the database.  Is there a script, macro, or command line option I can use to do this?  Thanks.

RE: Automatically Update Linked Tables

I'm not sure what you mean by "refresh". Linked tables display live/current data from the source.

I created an MDB linking to some tables on an AS400.  I thought the data was stored in the MDB and needed to be refresed by updating them using the linked table manager. No?

 

RE: Automatically Update Linked Tables

If the tables are linked rather than imported, the data should be "fresh".

OK. I figure this out:  I couldn't understand how a 1/2 gig database could be "live" constantly and didn't need to be refreshed.  

So I ran a query, changed a record in the database, ran the query again and the data was updated. I was surprised.

What happened was when I originally created the database I had imported the data, then ended up doing some research and creating linked tables instead and deleting the original tables.

I did a compact and repair and now the MDB file is small.

One thing I don't understand is why running a Crystal Report against an AS400 database is slow, but running the same Crystal Report against Access tables that are linked to the same AS400 database is lightning fast.
