I'm trying to wrap my head around this... (it may be simple, been a long day!)

I have a database with sometimes multiple similar records...

ie.

Apples 2008-09-03
Apples 2012-01-01
Apples 2013-10-24
Oranges 2012-01-04

What I need to do is do a query that will show only records that haven't been updated today...

So in this case, since Apples has an entry that was updated today, none of the records for the Apples should appear in the results.

Oranges should be the only record it returns.

I have a query similar to this...

SELECT fruit FROM fruitnames where date < CURDATE()

Which works to remove the record that was updated today... But it keeps the other records for Apples (obviously)...

How would I remove those results as well?
