You could use 'group by' like so.
x = value that is either distinct or not distinct:
Select x, count(*) from table_where_x_is_in group by x having count(*)>1;
Hope that helps. (BTW, you can also combine fields, but they have to appear
in the 'select' and in the 'group by' part. More in the really good manual).
I hope that accomplishes what you wanted.
