Re: Query taking a lot of time if there is no record in table

The way to get that to use the index is slightly complicated: 
  AND RATE_TIME >= ?
  AND RATE_TIME <  DATE_ADD(?, INTERVAL 1 DAY)
Substitute the date (eg, '2008-11-01') for both the '?'.
The inequalities are designed to correctly handle midnight.
