If this is correct, then you need to create an append query (Select Append from the query menu) in the current database based on the daily table. You will be prompted for the table that you want to append and you will have two options : Current DB or External DB. Select External and navigate to the DB. You will then be prompted for the table in the external DB.
When you run the query, the data in the external database will be appended.
If you need to manage this through code, use the docmd.runquery qryname.
Note The user will be prompted that X records are about to be appended to a table. If you do not want the user to see these messages, set showwarnings to false.
Let me know if we are on the right path here. I hope I have understood you question.
If you need any clarification, let me know.
