Can't get ByCode mapping to produce not nullable varbinary(max)
---------------------------------------------------------------
Key: NH-2739
URL: http://216.121.112.228/browse/NH-2739
Project: NHibernate
Issue Type: Bug
Components: Mapping by-code
Affects Versions: 3.2.0Beta1
Reporter: Michael Teper
Priority: Major
Trying to map the following class:
public class MyData
{
public byte[] Data { get; set; }
}
to 'varbinary(max) (not null)' field in SQL Server 2008.
mapper.Class<MyData>(map =>
{
map.Property(x => x.Data, m => m.Length(int.MaxValue));
map.Property(x => x.Data, m => m.NotNullable(true));
});
produces 'image(null)'

Andrei updated NH-2736:
-----------------------
Attachment: Debug.jpg
Hello,
I don't know if this can help identifying the issue, but I'va noticed that the SqlString generated in the Translator of the HQLQueryPlan doesn't set the BackTrack property for the o0 parameter but it set for the o1 parameter as you can see in the attached image.
I've also noticed that if I set the BackTrack property for the parameter (using the debugger window) the query executes correctly.

---------------------------------
Ok Andrei thanks for the issue.
The skip/take with parameter are already suffering some bugs due to the no-meaning Parameter way NH manage parameters all around the code.
Patrick are working in another big refactoring to cut the problem at its root.
I'll find a workaround just for this release.

-------------------------------------
More like 9 months, but yeah... I haven't had time to do this, plus I'm working in a project with EF now :-(
The general scenario has changed, though. With NuGet, I could publish this as an addon more easily. But I still feel like this could be part of the core; don't close it yet.

Exception thrown when mapping contains empty enum
-------------------------------------------------
Key: NH-2738
URL: http://216.121.112.228/browse/NH-2738
Project: NHibernate
Issue Type: Bug
Components: Mapping by-code
Affects Versions: 3.2.0Beta1
Reporter: Michael Teper
Priority: Minor
I was playing around with new mapping by code and ConventionModelMapper and ran into an "Array ouf bounds exception". Turned out that one of my entities had an enum property and the enum was empty (I haven't yet added any values). As this was a pretty trivial project, the issue was easy to track down but it would be great if this was handled better by NH. Either this should be ignored (what's the harm?) or the error message should point out the empty enum and the class that was referencing it.
Thank you!

CLONE -Inverted parameters in HQL statement using take
------------------------------------------------------
Key: NH-2737
URL: http://216.121.112.228/browse/NH-2737
Project: NHibernate
Issue Type: Bug
Components: Core
Affects Versions: 3.2.0CR1
Reporter: Andrei
Hello,
When I create a HQL query using parameters the parameters are inverted.
Here is an example (I'll attach a test as soon as I have the issue number):
var query = session.CreateQuery("select o.Id, i.Id from SalesOrder o left join o.Items i with i.Quantity = :p0 take :p1");
query.SetParameter("p0", 1);
query.SetParameter("p1", 2);
var result = query.List();
Assert.That(result.Count, Is.EqualTo(2));
The SQL Statement is:
exec sp_executesql N'select TOP (@p0) salesorder0_.Id as col_0_0_, items1_.Id as col_1_0_ from SalesOrder salesorder0_ left outer join Item items1_ on salesorder0_.Id=items1_.SalesOrder and (items1_.Quantity=@p1)',N'@p0 int,@p1 int',@p0=1,@p1=2
So the query selects the top 1 rows and the quantity column is filtered with 2.
Probably this bug is related with the implementation that allows to specify the take rows using parameters.
Thanks,
Andrei

Fabio Maulo closed NH-2736.
---------------------------
Resolution: Won't Fix
You are using NH's internals parameters names.
The usage of "p" followed by a number is not allowed as user-parameter-name.
Those parameter-names are reserved by NHibernate.

Andrei Alecu commented on NH-2734:
----------------------------------
Ok, bare with me for a second please:
Based on what you're saying, this shouldn't work either:
from Being b where b.class = Alien
However, someone was smart enough to add some special handling so that in this case the class name is converted to its SQL discriminator value, as I mentioned in the comments in NH-2328.
Please look at LiteralProcessor.cs line 153:
// IDENT might be the name of a class.
IQueryable queryable = _walker.SessionFactoryHelper.FindQueryableUsingImports(constant.Text);
if (isIdent && queryable != null)
{
constant.Text = queryable.DiscriminatorSQLValue;
}
*That* little fix however is unfortunately incomplete, and does not work in all cases... classes mapped as <any> do not have explicit discriminator values assigned to them, because they could be used in several mappings with several different discriminator values.
I believe the proper fix would've been to parametrize the equality for .class=? so that NullSafeSet() would be called by default, and MetaType would itself handle this scenario.
This way, the fix would be consistent for *BOTH* of these scenarios.
Please give this some thought before dismissing it as not being a bug, it is not good API design to have such terribly inconsistent behavior and consider it by design. :)

Inverted parameters in HQL statement using take
-----------------------------------------------
Key: NH-2736
URL: http://216.121.112.228/browse/NH-2736
Project: NHibernate
Issue Type: Bug
Components: Core
Affects Versions: 3.2.0CR1
Reporter: Andrei
Hello,
When I create a HQL query using parameters the parameters are inverted.
Here is an example (I'll attach a test as soon as I have the issue number):
var query = session.CreateQuery("select o.Id, i.Id from SalesOrder o left join o.Items i with i.Quantity = :p0 take :p1");
query.SetParameter("p0", 1);
query.SetParameter("p1", 2);
var result = query.List();
Assert.That(result.Count, Is.EqualTo(2));
The SQL Statement is:
exec sp_executesql N'select TOP (@p0) salesorder0_.Id as col_0_0_, items1_.Id as col_1_0_ from SalesOrder salesorder0_ left outer join Item items1_ on salesorder0_.Id=items1_.SalesOrder and (items1_.Quantity=@p1)',N'@p0 int,@p1 int',@p0=1,@p1=2
So the query selects the top 1 rows and the quantity column is filtered with 2.
Probably this bug is related with the implementation that allows to specify the take rows using parameters.
Thanks,
Andrei

Fabio Maulo commented on NH-2734:
---------------------------------
Is not a bug because when you use a parameter is supposed that NH may have some way to understand how assign it.
Probably you are using meta-values... in this case the "secret" db-representation is your own representation.
Try to avoid meta-values and let us know what happen specifying a class in hql-line instead use a parameter.

Andrei Alecu commented on NH-2734:
----------------------------------
I don't think that's right Fabio.
See the test in UnionSubclassFixture.cs.
Assert.AreEqual(1, s.CreateQuery("from Being b where b.class = Alien").List().Count);
This works properly for classes mapped as a hierarchy, and you don't need to use any secret type.
Not being able to use the same query on <any> mappings is not consistent and I don't see it documented anywhere, if you can point me towards documentation it would be great.
Anyway, something working as a parameter, but not as a literal in a HQL query does not make sense to me. I would still consider this to be a major bug.
Also note that this works:
var boxes = s.CreateQuery("from ToyBox t where t.Shape.class = 2").List<ToyBox>();
But this does not work:
var boxes = s.CreateQuery("from ToyBox t where t.Shape.class = :clazz")
.SetParameter("clazz", 2)
.List<ToyBox>();
I don't see how this inconsistent behavior is not considered a bug.
The only problem is, trying to come up with a fix is probably non trivial. I'm not sure if Hibernate is affected or not, or if they fixed this already.

Fabio Maulo closed NH-2734.
---------------------------
Resolution: Not an Issue
The NullSafeSet is not called because you don't have something to set.
When you use a constant, in the HQL, to compare a special not existent property (as 'class' or 'id') you have to know its "secret" type/db-representation.

> Reporter: Andrei Alecu
>
> Querying a property defined with an <any> mapping by its id needs to use the special .class and .id properties defined by HQL.
> Not having a way to access .id makes it impossible to translate queries such as the following to Linq:
> from ToyBox t where t.Shape.class = Square and t.Shape.id = 1 (note that there's currently a bug with .class at NH-2734)
> Note that accessing the identifier property mapped as .Id (non lowercase) does not work, the HQL query parser complains that there's an access to an unmapped property .Id.
> My current workaround is to define this extension method as a custom linq generator:
> public class ImplicitIdGenerator : BaseHqlGeneratorForMethod
> {
> public ImplicitIdGenerator()
> {
> this.SupportedMethods = new[] { ReflectionHelper.GetMethodDefinition<object>(x => x.ImplicitId()) };
> }

> I believe the special .id property may also be used in other circumstances when the name of the property used for the identifier is not known.
> I'm not sure if this is the most elegant implementation, but this code lets you do this:
