However, after executing that query, it then still proceeds to do the N+1 select on FdeOrganization. > As in this application I'm actually using quite a few cases where I'm successfully using the inner join fetch technique against FdeOrganization, I can only assume that this is a problem related to key-many-to-one rather than many-to-one. > After further investigation, I can establish that Hibernate 3.1.3 exposes the exact same functionality. I'm filing this first against NHibernate since that's where I first discovered it, however, since it affects Hibernate as well it might be better filed against that, and I can do so if needed. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.nhibernate.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira |

Custom load-collection with Stored Procedure
--------------------------------------------
Key: NH-794
URL: http://jira.nhibernate.org/browse/NH-794
Project: NHibernate
Type: Bug
Components: Core
Versions: 1.2.0.Beta1
Reporter: Bill Pierce
Priority: Minor
Attachments: NHibernateSqlLazyLoad.zip
I am using a custom loader to load a collection using a Stored Procedure. The SQL executes just fine, data is returned from the sproc, the objects appear to be hydrated just fine, however the resulting IList is empty when I try to iterate it or get a .Count. No errors are thrown and everything else appears to be working normally. I tried lazy/non lazy, tried using a Set instead of a Bag, but nothing seems to be working.
Attached is a small project + sql files needed to recreate the issue.
