Dear List: Three back end tables - ActionGroups, Actions, and ActionDates. These are mirrored by ActionGroupsTemplates, ActionsTemplates, and ActionDatesTemplates in the front end. Actions is a child of ActionGroups - one to many relationship with ActionGroupsID as a FK. ActionDates is a child of Actions - one to many relationship with ActionsID as a FK. When the front end is updated, I need to delete all of the records in the three back end tables that have their Template flag set to True (there may be user defined Actions in the back end that need to stay there) and replace them with the front end tables' records. I thought a few simple db.execute "Delete *..." and db.Execute "INSERT..."s would do it. But since the PK of ActionGroups is going to change when the records are added to the back end, I'd need to make the new FK of Actions the PK of the new ActionGroups record and the new FK of ActionDates the PK of the new Actions record. So it can be done with a bunch of code - I've done that before. But is there a more elegant way?
