Обсуждение: Oops...

With respect to my previous query, I'd like to clarify that the FETCHes I
am doing are subsets of the full results (hence I cannot use PQntuples).
For instance, I am FETCHing 25 records out of a possible 1000, so
PQntuples() is returning 25.  I need some way of knowing there's a 1000
total.

Thanks,

Mike.

Why can't you get the number of the initial results before fetching them
page by page?  If you create an initial query and save it as a view, why
can't you grab the number out of that first result set (via a ntuples
function call or by executing an SQL statement), then page through it with
your cursor?  Or can cursors not be created from views?

If the human brain were so simple that we could understand it,
we would be so simple we couldn't.

simple - first try "select count(*) from ...",
and then "declare ..." and subsequent fetches.
