This sample illustrates how to create a  query which displays the BeginDate and EndDate of a range based on a single EffectiveDate stored in the table. 

It is assumed that the Effective Date range of a record spans the time from the Effective date of the current record and the Effective Date of the NEXT record (minus 1).

There are three methods shown here: Using a 1) correlated subquery, 2) DMax domain aggregate function, and 3) LEFT OUTER JOIN.
