Is there a (better) way to get the toal number of results from a query
but still limit them with a LIMIT clause. For example, in a Google
search result, it displays 1-100 of 10,000,000 results. Do they hit
the database once for results, and again for a total count or is it
all in one query? Thanks -Nick 5 2675
interesting.
I've noticed that if the amount is a big number, google gives only a approx
number.
And sometimes a small amount is not accurate to the real result number that
google returns.
I personal believe there's some stat in their index.
Waiting for more info here with Nick :-)

Don’t know what google is doing, but e.g. PHPBB bulletin board queries
completely, and then only shows the top xx results. So it does not do
a limit.
You can easily do a benchmark between:
(a) doing two queries, one using a limit
(b) using a single query, and then showing the top xx results
Otherwise, I don’t believe what you asking is possible.

I would like to paginate the results of a query on several pages. So I

But for the first page, I need to run the same query with a count(*)
to know how many pages I will get (number total of rows/ X).
The problem is my query is very slow (maybe 5s) because there is much

I'm implementing paging through search results using cursors. Is there a
better way to know total number of rows under a cursor than running a
separate COUNT(*) query? I think PostgreSQL is bound to know this number
after the first FETCH, isn't it?
On a side note, why queries using LIMIT are SO terribly slow, compared to
cursors and sometimes even ones without LIMIT? Shouldn't LIMIT be internally
implemented using cursor mechanism then?...
