Duane is correct, two for two.
To create an append query, from the menu...
- Insert -> Query
- Select Design view
- Add your table or tables
- Create a query
- Convert to an Append query, from the menu, Query -> Append
- Indicate which fields in the source table will be appended in the target table.
- View the test results, View -> Datasheet
- Toggle back to design or SQL view
- If satisfied, run the update
Always a good idea to have a backup plan before running a large update.
If you are trying to update just one record, or a select few records, you can use the Append query created with the above as a template in SQL view to be used with VBA code.
