Hello,
I've got a table of shows with different types (movie, theater,
ballet,etc.) and I am looking for a select that can return the 10 last
entered shows AND at most 2 of each type. Is that possible in one query?
The table looks basically like:
created_on | timestamp without time zone
show_name | text
id_show | integer
show_type | text
id_show_subtype | integer

TIP 2: Don't 'kill -9' the postmaster
Looks like a top n query and whilst there are many top-n query solution
I'd refer you to a Joe Celko solution.
Check the "top salesperson contest" and I think you should be able to
work your problem (http://www.dbmsmag.com/9610d06.html)
