Creating a "Most Popular Pages" List

Question

The setup's like this:
* Each page that is tracked has a SQL statement that increments the number in an "occurances" column in a table specifically made for this purpose.
* The db_occurances table has three columns - page number, page name, and occurances.
* The main page of the application has a PL/SQL anon block region that is supposed to display the two most visited pages in list form.
* The main page contains four hidden items that each have a SQL query; they have a value equal to something like this:
select pagename from (select rownum r,pagename from db_occurances order by occurances desc) where r = 1;
* The main anon block takes the values of these four items and uses them to build the list of popular pages.
The part that doesn't work is the SQL query in the four items. Instead of ordering the rows by occurances in descending order as they're meant to, they're ordering the rows as they appear in an unordered query.
Doing a SQL query "SELECT pagename FROM db_occurances ORDER BY occurances DESC" in the SQL Workshop returns the correct order.
Anyone have any idea what could be the problem?

Hi Ben,
This should work for you -
  1  select * from
  2  (select
  3    application_id,
  4    page_id,
  5    page_name,
  6    count(*) as times_viewed
  7  from
  8    apex_workspace_activity_log
  9  where page_id in (1, 9, 56)
10  group by
11    application_id, page_id, page_name
12  order by times_viewed desc)
13* where rownum <= 3
jes@TESTDB> /
APPLICATION_ID    PAGE_ID PAGE_NAME            TIMES_VIEWED
           463          1 Home                           42
           348          9 Home                           31
          4000         56 Application Builder            19Obviously you could adapt this query to pass in the page id's (or do a subquery to retrieve them from another table etc).
Hope this helps,
John.
