Select statement issued for each not-found=ignore
-------------------------------------------------
Key: NH-1001
URL: http://jira.nhibernate.org/browse/NH-1001
Project: NHibernate
Type: Bug
Components: Core
Versions: 1.2.0.Alpha1, 1.2.0.Beta1, 1.2.0.Beta2, 1.2.0.Beta3, 1.2.0.CR1, 1.2.0.CR2, 1.2.0.GA
Reporter: Tomer Avissar
Priority: Minor
When using the not-found=ignore attribute in a one-to-many/many-to-many, NHibernate is issuing a query for every element not found in the collection, even when using an outer join.
In some cases this causes a significant performance overhead.
