It is possible the executing a 'MoveLast' on the record set and then looking at the record count MIGHT show where additional records have been appended.
But based on my personal experience, execution might be quicker and will definitely be more reliable to use Vanikcz's suggestion of using the count query.
Actually, for a system where the number of records would not be changing while a process was executing, we used to process records by first building a WHERE clause in a variable, and pass that clause to a function with code that lookes something like this:
SQL$ = "SELECT COUNT(*) AS COUNTER FROM " & TABLE$ & " " & WHERE$
Set RS = DB.OpenRecordSet(SQL$, dbOpenForwardOnly)
RecordCount = CLng(RS!COUNTER.Value)
We would then reuse the WHERE$ in building the actual query so that the number of records returned were sure to match the count queried (assumeing the number of records had not changed since the count query was executed).
