Thnx a lot Andreas, but the query you gave me has not the desired result.
when i select id,imdb_id,count(imdb_id) from "Movies" where id<10 group 
by imdb_id,id order by id asc;
what I get is
id | imdb_id | count
----+---------+-------
1 | 315733 | 1
2 | 315733 | 1
3 | 315733 | 1
4 | 315733 | 1
5 | 315733 | 1
6 | 315733 | 1
7 | 315733 | 1
8 | 315733 | 1
9 | 315733 | 1

The desired result is
something like
id | imdb_id | count
----+---------+-------
1 | 315733 | 9
10 | 335753 | 1
11 | 320000 | 15
etc.
