I haven't attempted to do this yet but I was wondering. I have DB1 which has a table dedicated to days off for soldiers. I want to link DB2 to that table in DB1 so that I can make a calendar in DB2 for users to see when people are off and for how long. If I go to the external data tab and select access database and choose the table i want from DB1, is that a 1 time pull or will it be constant?
