Question

I have two Oracle SQL Tables:

Team and Work.

I want to select all the columns from the team table (this is fine) for three teams that appeart the most in the work table.

Team (teamId, name)
Work(workId, name, teamId).

I really don’t know how to select from count max.

my first idea was to group the work table by the count of teamId but I can’t group in a subquery…

Hope everything is clear, if not let me know.

Answer 1

Should be something like this (not quite sure about syntax):

select * from team where teamid in (
   select teamid from (
      select teamid, count(workid)
      from work
      group by teamid
      order by 2)
   where rownum < 4);
