Clear/Refresh Cache

[AgDawg]

I have an access 2007 database with 2 linked sharepoint 2010 lists. I update records a few times a week but sometimes I have a lot of records to update at once so I use an update query to update the list. The end users have their own customized database based upon the market they are located in. So my problem/question....While my database updates fine and I can verify the changes in sharepoint in the end users databases the linked list doesn't update. I have tracked this problem to the cache. When I click do not cache data the data is updated. Is there any code I can write to clear the cache? Just for reference clicking the refresh list icon at top does not work. The data is just isn't being updated in the cache when I do some of these mass updates sometimes. If I can put a command button for the user to clear the cache this would at list ensure they have the latest data.
