[nhibernate-issues] [JIRA] Commented: (NH-1001) Select statement issued for each not-found=ignore

[NHibernate J. <mik...@us...>]

     [ http://jira.nhibernate.org/browse/NH-1001?page=comments#action_15540 ]
     
Tomer Avissar commented on NH-1001:
-----------------------------------

I want it to skip the subsequent queries for the child objects. 

Since an outer join was performed, NHibernate already "knows" the child records don't exist, so there is no use in requerying the table.

>          Key: NH-1001
>          URL: http://jira.nhibernate.org/browse/NH-1001
>      Project: NHibernate
>         Type: Bug
>   Components: Core
>     Versions: 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.
