how to do group by having count in case insensitive?thank you very much

hi

   i'd like to ask is it possible to make a query of  group by  having count in case insensitive?

   for example

select name from table group by name
having count(name)>1 

  but i hope i can find  the "name" whose count is greater than 1,but including case insensitive.thank uvery much

best regards

martin
