I have attached the result of a UNION.  Where there are duplicate categories, I do not want the NULL hour/date record.  When the NULL hour/date record is the only one for a category, then I want to keep it.

 When the How can I do this?  

here's the SQL

SELECT Category , annualhours AS Hours,  Date AS Date  

FROM training_details_report
where EmpUID = 2368 and annualhours > 0 and
(date BETWEEN '1/1/2011' AND '12/31/2011')


select Category, null as hours, null as date from BCS_Training_Categories
