Fabio Maulo updated NH-2700:
----------------------------
Fix Version/s: (was: 3.2.0Beta2)
> SqlFunctionProjection does not honor parameter order
> ----------------------------------------------------
>
> Key: NH-2700
> URL: http://216.121.112.228/browse/NH-2700
> Project: NHibernate
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.1.0
> Reporter: Andrei Alecu
> Assignee: Patrick Earl
> Priority: Minor
> Attachments: nh2700 failing test.patch
>
>
> If you define a function in a custom dialect that does not have the parameters in order and use SqlFunctionProjection, the generated sql is wrong, and does not honor parameter order.
> For example:
> RegisterFunction(
> "AddDays",
> new SQLFunctionTemplate(
> NHibernateUtil.DateTime,
> "dateadd(day,?2,?1)"
>
> )
> );
> var proj = new SqlFunctionProjection("AddDays", NHibernateUtil.DateTime,
> new IProjection[]
> {
> Projections.Property<ModelClass>(p=>p.Date1),
> Projections.Property<ModelClass>(p=>p.Value1)
> });
> Generated SQL (buggy):
> SELECT dateadd(day,this_.Date1,this_.Value1)
> Expected SQL:
> SELECT dateadd(day,this_.Value1,this_.Date1)
> Using an HQL query honors parameter order properly
> I will attach a failing unit test.
