The "from_datetime" column is of type "timestamp" but I want to check
only the date, not the time.
In this example I want to retrieve all records whose "from_datetime" is
e.g. >= 2009/05/06 (Now()) so I'd like to get results with a
"from_datetime" like e.g.
- 2009/05/06 00:05:00
- 2009/05/06 23:30:00
- 2009/05/07 10:15:00

Nico
