Just a correction, dates in mysql are not strings by any means, they are
stored in 3 bytes (date and time or 8 bytes for datetime) and that's

formatted string, so for all intents and purposes any comparison to a date
field should be using quotes like mentioned already.

I didn't intend to suggest that dates in mysql were STORED as strings,
just that in the SQL Statement they were treated as strings.
