This sample illustrates how to create a Previous Date query. It shows how to:
1) Display the previous date in subsquent records of a table
2) Display the previous date in subsquent records of a table over a group. In this case, the group is the OrderID field.
There are two methods shown here: Using a 1) correlated subquery and 2) DMax domain aggregate function. The correlated subquery is the faster method, but it returns a non-updateable recordset. The DMax method is slower, but the recordset is updateable.
HOWEVER, it should be noted that against a large dataset, neither method will be very fast!
Access 2000-2007 version: PreviousDateQuery.zip
NOTE: If you want to know the number of days between the two dates, see my sample: DaysBetweenQuery.mdb.
