I suspect you'll need both the paged query and the count. See the discussion here:
http://groups.google.com/group/nhusers/msg/0bcda99c81248e17 http://groups.google.com/group/nhusers/browse_thread/thread/16c296414aedc09d There's also a method on IQueryOver called ToRowCountQuery() that will clone the query, remove the paging, and project the rowcount, allowing you to use futures too: myPagedQuery .ToRowCountQuery() .Future<int>(); From: Mohamed Meligy Sent: Tuesday, March 23, 2010 7:51 AM To: [email protected] Subject: Re: [nhusers] How do I get row count using the NHibernate QueryOver api? I think you just need to make the call (Count) BEFORE the paging code (Take, Skip). -- Mohamed Meligy Senior Developer, Team Lead Backup (.Net Technologies - TDG - Applications) Injazat Data Systems P.O.

I would like to get a row count, but the method I'm using returns all objects and then gets the count of the collection. Is there a way to just return an integer/long value of the number of rows without returning all of the row data? I'm currently using: _session.QueryOver<MyObject>().Future().Count() if it matters, that call is being used right after one like: _session.QueryOver<MyObject>().Skip(pageId-1 * PageSize).Take(PageSize).Future(); Thanks for any help with this, Jim -- You received this message because you are subscribed to the Google Groups "nhusers" group.
