Output of a query

Question

Hi,
I have the following query:
SELECT site
FROM ( SELECT date_1, date_2, site
FROM test
ORDER BY 1 DESC)
WHERE ROWNUM < 10;The result has 9 rows with some A or B
I want to print
- successful if I get A's and B's
- unsuccessful if I get only A's or only B's
How can I achieve that ?
Thanks for your help

Assuming site is either A or B:
SELECT  site,
        case count(distinct site) over()
          when 2 then 'successful'
          else 'unsuccessful'
        end
  FROM  (
         SELECT  date_1,
                 date_2,
                 site
           FROM  test
           ORDER BY 1 DESC
  WHERE ROWNUM < 10;If site can be other than A and B:
SELECT  site,
        case count(distinct case when site in ('A','B') then site end) over()
          when 2 then 'successful'
          else 'unsuccessful'
        end
  FROM  (
         SELECT  date_1,
                 date_2,
                 site
           FROM  test
           ORDER BY 1 DESC
  WHERE ROWNUM < 10;SY.
