Nope! Look carefully at the generated SQL. It is correct! It
defines an alias "user" for the table user_sys_access. That
SQL would execute perfectly on Oracle, except for the fact
that "user" is a reserved word. So you need to use a different
alias in the HQL. eg:

from u in class User where u.username =3D ?

("u" is not a reserved word)

I don't understand how this could possibly not execute on Orace!
Are you sure there is a column in the table named "user_id"??

Is User0 a reserved word for some bizzare reason???

When I had a first look at the JDO API, I really liked

PersistenceManagerFactory
PersistenceManager

Why not use the good things from JDO? :)

Re: [Hibernate] Oracle error

[Matt R. <mat...@ca...>]

Here's the SQL that Hibernate is generating for me:

    [junit] Hibernate: SELECT user.user_id as user_id, user.changed_by as
changed_by, user.created_by as created_by, user.dt_changed as dt_changed,
user.dt_created as dt_created, user.headend_id as headend_id, user.mso_id as
mso_id FROM user_sys_access user WHERE (user.user_id=? )

And it should be using "user_sys_access" rather than "user".

I tried changing it to just load the record based on the Id (no OQL):

user = (User) ses.load(User.class, userId);

And I get an invalid column name error on User0.user_id.  Is it possible to
get rid of the User0 prefix that's causing these problems?  Attached is my
User.hbm.xml.

    [junit] Hibernate: SELECT User0.user_id AS user_id, User0.changed_by as
changed_by, User0.created_by as created_by, User0.dt_changed as dt_changed,
User0.dt_created as dt_created, User0.headend_id as headend_id, User0.mso_id
as mso_id FROM user_sys_access User0 WHERE User0.user_id = ?

Thanks,

Matt

LOL :))

I'm not actually sure that there are any commonly accepted=20
names for this pattern. The Hibernate Session is *almost*
similar to UnitOfWork except for the fact that it is _not_,
actually, an atomic unit of work. Neither is it quite like
the ODMG Database or JDO PersistenceManager which, by their
names, imply a long-lived, singleton-style object.

How are you planning on supporting this?  Is there going to be some 
internal changes in Hibernate to support them, or are you just going to 
add new Blob and Clob types?

Maybe this recommendation is a bit unpopular: 

Get rid of the name "Session"! I spent the last three days implementing
lazy loading in a clean separated Three-Tier-Architecture and it's
driving me crazy. Whenever I read the documentation, I also had this 100
milliseconds think time when I hit the word "Session" or "Transaction"
until I realized that the statement was about the Hibernate thing, not
about the _concepts_...

Well, I have to manage two layers of Session Beans (stateful and
stateless), a HttpSession containing a UserSession and some other stuff
named similar. My code is clean, but the next developer looking at this
stuff will have a hard time understanding why there's another "Session"
in the Persistence Layer that uses UserSession to store its disconnected
state and gets this one from the SessionContext of the stateless
SessionBean Business Facade. And this was only have the system up from
the bottom, there are some other "Sessions" in the top layer.

Ok, it's not that serious, but I feel alot better already ;)

[Hibernate] Road Map

[Gavin K. <Gav...@ex...>]

Future plans:

Next release: 1.2.1
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
* various bugfixes
* full support for Clob and Blob
* FlushMode API + deprecation of suspend/resumeFlushes
* Improved logging of bind variables, etc.

1.2.1 is almost ready to go. Should be released in one=20
to two weeks. This will be a very stable platform for=20
development and we should continue to fix any bugs in=20
the 1.2 branch concurrently with 2.0 development.

Hibernate 2.0 beta
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
* create a new module in CVS with improved directory=20
  structure
* rename packages to net.sf.hibernate
* replace existing configuration mechanisms=20
  with an interface that unifies the functionality
  of HibernateService, (the misnamed) Datastore,
  Hibernate.configure() and Configuration.
* query language enhancements, starting with:
  - OUTER JOIN, FULL JOIN, etc
  - AS instead of IN, IN CLASS
  - select new Foo(bar.name, bar.count) from .....
* JCA implementation
* removal of support for toplevel collections /
  subcollections

That list of features (for 2.0) should be considered a=20
proposal. If anyone thinks there are more urgent things
than those listed (ie. more urgent for the user base as
a whole, rather than for themseleves personally), we can
vote on it.

Something I would like everyone to consider and vote on=20
at this stage is:

Should 2.0 be 100% backward compatible with 1.2?

Because almost everything is defined by interfaces (and=20
because I don't envisage any change in semantics for
any operations of the core interfaces), we *could*=20
continue  to support the existing interfaces alongside=20
the "new" net.sf.hibernate.* interfaces.

However, I am quite keen to actually rip out a lot of code
relating to support for toplevel collections and the various
old configuration mechanisms.

I see three possibilities here:
(1) make a clean break - most applications will be portable
    to 1.2 with nothing more than a few simple text search/
    replace (s/cirrus.hibernate/net.sf.hibernate). This will
    mean less code to manage / distribute.
(2) continue to support certain core interfaces:
    - Session
    - SessionFactory
    - UserType
    - Hibernate
    - Query
    - ScrollableResults
    - ???
(3) Full backward compatibility

Lets discuss / vote on this now, even though we won't be=20
starting work on 2.0 for a few weeks now. People voting for
(3) will be assumed to be volunteering for some of the=20
extra work involved in implementing / maintaining this ;)

I suspect that many people would be tempted to vote for (2).
But is there really *that* much value in that for the users?
The interfaces themselves arent changing, so its a simple
search/replace followed be recompile.

peace

Gavin

RE: [Hibernate] Oracle error

I changed it to use this error and I'm still getting the same error.  I'm
guessing that my table name is irrelevant as long as it's in the
User.hbm.xml file.  

Is there anyway to turn on debugging so I can see the SQL being sent?

RE: [Hibernate] Enhancements to the Hibernate Xdoclet subtasks

[Gavin K. <Gav...@ex...>]

I meant to say a big thanks to Joel for his work on this.=20
Actually I intend to remove the Tools module fairly soon,=20
since the XDoclet CVS is now considered the home of=20
Hibernate XDoclet.

Actually the Hibernate XDoclet module has moved under the umbrella of
the XDocklet project proper.  Until the next XDoclet release, it is only
available by downloading all of XDockle from cvs on Source Forge and
building it. I suppose that if that was really inconvenient, one could
always download the one from the Hibernate Tools cvs tree, but that no
longer has the latest modifications.

[Hibernate] Oracle error

[Matt R. <mat...@ca...>]

I am trying to use Hibernate to connect to Oracle.  I was using MySQL -
where everything worked.  All I've changed (so far) was the tablename from
"user" to "cct_user".  Now I'm getting the following error:

   [junit] Testcase:
testGetUser(com.cable.comcast.dmc.itd.cct.persistence.ApplicationDAOHibernat
eTest):     Caused an ERROR
    [junit] java.sql.SQLException: ORA-00923: FROM keyword not found where
expected

    [junit] com.cable.comcast.dmc.itd.cct.persistence.DAOException:
java.sql.SQLException: ORA-00923: FROM keyword not found where expected


I'm guessing there's something wrong with this code:

List users = (List) ses.find("from user in class
com.cable.comcast.dmc.itd.cct.persistence.User where username=?",
name, Hibernate.STRING);

Thanks,

Matt

[Hibernate] multiple beans in one table

RE: [Hibernate] Are toplevel collections / subcollections a Bad Thing?

My $0.02 would be to eliminate it.  It seems like a marginal feature at
best (a scary confusing feature at worst) and if it makes the code
simpler, get rid of it.

I'm (again) considering deprecating toplevel collections and

in Hibernate 2.0. I was never completely happy with this feature after I

implemented it, but it had taken so much effort to get it to work that I
left it in.=20

The case against toplevel collections is:=20
* the relational model is broken - there is no foreign key constraint
from=20
collection element row to the owning row=20

Re: Bi-directional relationships (was Re: [Hibernate] Are toplevel collections / subcollections a Bad Thing?)

[Max R. A. <ma...@eo...>]

Should we implement this paradigm in the codegenerator ? (of course as an
option)

Maybe something like this:

<property name="parent" class="eg.Parent">
 <metaattribute name="CodeGen.genCompositeGetSet" value="true"/>
</property>

Where the codegen would generate something like the code below if
"CodeGen.genCompositeGetSet" is set for the property and/or relationship.

Thats exactly what I'm doing:

class Child {

    public setParent(Parent newParent) {

        // Remove myself from old Parent
        if (this.parent != null) {
            this.parent.getChildren().remove(this);
        }

        // Add to new Parent
        newParent.getChildren().add(this);

        // Set new Parent
        this.parent = newParent;
    }
}

This is similar to the Composite Pattern (or better, a part of it):

Thanks - I'd used the advance in Tom's manual to do the mapping, but I
was trying to maintain the relationship in my persistent objects
(rather than making the client do it, as in the FAQ), which was
probably the cause of my problems.

Thanks,

I've just submitted a bug report. But don't expect a patch anytime soon, 
I've just started playing with Hibernate a couple of days ago and 
haven't even downloaded the source, yet.

Nice piece of work, BTW.
