I want expert suggestion on this.
I have an excel db with unique ID.
I want to create and maintain an Access DB based on this unique ID.
The excel file I get everyweek contains previous 3 weeks of data. So every week, when I append to Access db, I have to remove 2 weeks of data (date method) OR remove all the unique IDs that are present on both files.
I don't want to go through the 'date method' as user entry errors are present in Excel file hence automating it would ruin the db.
I want to know how I can compare each unique ID in excel with Access?
Do I take the access database into a temp table (call it AccessTable), then delete each unique ID that is present on ExcelTable - that just go imported?
^ This seems to be the best idea. However, if you can show me the resource to compare and delete duplicates inside Access, that would be great.
Rest, I can do!
Thank you for your time!
