I have a table containing jobs and dates that work was done on these jobs:

Job Date Work Done
A 01 Jan 2013
A 02 Jan 2013
A 03 Jan 2013
B 02 Jan 2013
B 03 Jan 2013
C 03 Jan 2013

I want to know which jobs started on say 02 Jan 2013 - the answer is job 'B'.

What would be the query for this?

Thanks.
