Hi all. This is not very "hackers"-related, but related to the topic of window-funcitons, which seems to be discussed quite a bit on "hackers" these days.
Can window-functions in PG be used to return "total number of rows" in a "paged result"? Say you have: SELECT p.id, p.firstname FROM person p ORDER BY p.firstname ASC LIMIT 10 OFFSET 10 Is it possible to use some window-function to return the "total-number of columns" in a separate column? In Oracle one can do SELECT q.*, max(rownum) over() as total_rows FROM (subquery) which returns the total number or columns in a separate column. This is very handy for web-pages which for example need to display the rist 20 results of several million, without having to do a separate count(*) query. -- Andreas Joseph Krogh <[EMAIL PROTECTED]> Senior Software Developer / CEO ------------------------+---------------------------------------------+ OfficeNet AS | The most difficult thing in the world is to | Karenslyst Allé 11 | know how to do a thing and to watch | PO.
