The _Tables_ come as Text Files? Isn't it more likely that the _data_ comes
as Text Files, to which you could link, or which could be imported into a
temporary table and manipulated from there to add the information to the
existing table, adding the year indicator?
You may have no control over what the government agency sends, but can't you
control what you _do_ with it?
How about this scenario:
1. Import text file into a Temporary Table.
2. Create a Query to determine which of the Records in the new Table are
already in the Permanent Table.
3. Use the Query from 2 above to create an Update Query to update the
information in the existing Records. Also update the "last updated" date, if
appropriate.
4. Create a Query to determine which of the Records in the new Table are
not already in the Permanent Table
5. Use the Query that indicates which Tables are not in the Permanent
Table to create an append Query to add them, along with the "last updated"
date.
6. Determine if you need to do any "deletions" based on the new data;
and do them.
