hbm2ddl.auto validate error on sequences in different schema
------------------------------------------------------------
Key: HHH-3526
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3526
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1
Environment: Hibernate 3.3.1 GA & Oracle 9i Database
Reporter: Andres Galeano
Hello,
My situation is that I have an persistent object and matching hbm that reference a table and sequence in a different oracle schema. When I set the "hibernate.hbm2ddl.auto" property to "validate", a hibernate error message claims that the sequence does not exist, although it does and is accessible.
>From stepping through the code
in class: org.hibernate.tool.hbm2ddl.DatabaseMetadata
in method: public boolean isSequence(Object key)
This code parses the 'key', in this case sequence name, by '.' and searches to see if the last element is contained in the list of sequences. So if I prefix my sequence name with the schema name it belongs to, it's ignored. This doesn't seem right to me.
The code also seems to ignore the "schema" attribute of the "hibernate-mapping/class" element when validating sequence generators. To me this seems wrong as well.
Since the 'list of sequences' is only for the current schema, at least in the case of Oracle9Dialect, the validate fails, even though the sequence does exist and seems to be properly specified to me.
------------------------------------------------------------
Excerpt from my hbm.xml file:
------------------------------------------------------------
...
...
<hibernate-mapping>
<class name="bus.Accesspurpose" table="ACCESSPURPOSE" schema="WISH">
<id name="id" type="int">
<column name="ACCESSPURPOSEID" />
<generator class="sequence">
<!-- Prefixed with schema for database validation. -->
<param name="sequence">WISH.SEQ_ACCESSPURPOSEID</param>
</generator>
</id>
...
...
------------------------------------------------------------
Full stack trace.

[Hibernate-JIRA] Created: (HHH-3231) org.hibernate.id.enhanced.TableGenerator throws "IllegalArgumentException: alias not found: tbl" under Oracle
by Király Attila (JIRA)
org.hibernate.id.enhanced.TableGenerator throws "IllegalArgumentException: alias not found: tbl" under Oracle
-------------------------------------------------------------------------------------------------------------
Key: HHH-3231
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3231
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6
Environment: Hibernate 3.2.6GA, Oracle 10g
Reporter: Király Attila
Attachments: hibernate_etg_ora.zip
org.hibernate.id.enhanced.TableGenerator always throws the following exception if I want to save a new object to Oracle:
java.lang.IllegalArgumentException: alias not found: tbl
at org.hibernate.sql.ForUpdateFragment.<init>(ForUpdateFragment.java:36)
at org.hibernate.dialect.Dialect.applyLocksToSql(Dialect.java:970)
at org.hibernate.id.enhanced.TableGenerator.configure(TableGenerator.java:194)
at org.hibernate.id.IdentifierGeneratorFactory.create(IdentifierGeneratorFactory.java:104)
I attach an example to this case. The example is loosely based on the tutorial example, that comes with Hibernate. It contains a Person object that is saved to db using the enhanced.TableGenerator as id generator. To keep the zip small only the jars of jdbc driver are included, the jars needed from hibernate distribution are listed in lib/readme.txt.
The zip also contains a modified TableGenerator that works with Oracle. This version was made by forum user stomp and more information about it can be read here: http://forum.hibernate.org/viewtopic.php?t=980933
It changes the 194th row of TableGenerator from
this.query = dialect.applyLocksToSql( query, lockMap, CollectionHelper.EMPTY_MAP );
to
this.query = dialect.applyLocksToSql( query, lockMap, Collections.singletonMap("tbl", new String[] {valueColumnName}) );

[Hibernate-JIRA] Created: (HHH-3771) Best pactice for equals implementation?
by Samppa Saarela (JIRA)
Best pactice for equals implementation?
---------------------------------------
Key: HHH-3771
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3771
Project: Hibernate Core
Issue Type: New Feature
Components: core, documentation
Reporter: Samppa Saarela
When domain model contains even one lazy reference to an object, default equals fails when it's compared to a) the actual implementation returned by Session.get/load or b) other proxies (at least of different supertype). Overriding equals on a class that uses surrogate id is not that simple. However there is a simple solution to this problem:
In domain class, override equals like this:
public boolean equals(Object obj) {
return this == getImplementation(obj);
}
public static Object getImplementation(Object obj) {
if (obj instanceof HibernateProxy) {
return ((HibernateProxy) obj).getHibernateLazyInitializer().getImplementation();
} else {
return obj;
}
}
This should result always in comparing object references of actual instances and thus preserve symmetry.
It's understandable that you don't wan to publish that kind of getImplementation utility e.g. in Hibernate, but maybe you could support this more directly by implementing
Hibernate.equals(Object o1, Object o2)

[Hibernate-JIRA] Created: (HHH-3908) Expose way to fully control fetching in native-sql queries in API
by Steve Ebersole (JIRA)
Expose way to fully control fetching in native-sql queries in API
-----------------------------------------------------------------
Key: HHH-3908
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3908
Project: Hibernate Core
Issue Type: New Feature
Components: core
Reporter: Steve Ebersole
Fix For: 3.5
Currently, in order to fully control fetching in native-sql queries, users must revert to using a named sql query (at least the xml, not sure if the annotations variety supports as well). We alreasy have all the objects/contracts in place to handle this for the named queries, just need to clean-up and properly document them.
The current API calls to deal with this are the overloaded SQLQuery#addJoin methods. Ideally I'd see these changed to return the representation of the join-fetch to be configured; but addJoin already defines a return : the query itself :( So probably we will need new methods like addFetch:
1) public JoinFetch addFetch(String alias, String ownerAlias, String ownerProperty)
2) public JoinFetch addFetch(String alias, String ownerAlias, String ownerProperty, LockMode lockMode)
interface JoinFetch {
public void addPropertyMapping(String propertyName, String sqlAlias);
}
This can be expanded to the "root returns" as well (currently the overloaded #addEntity methods):
public RootReturn addRoot(String alias, Class entityClass)
etc...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Example
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
SQLQuery query = session.createSQLQuery(
"select c.cust_id as cid, " +
" c.cust_name as cname, " +
" o.order_id as oid, " +
" o.order_num as onum " +
" from customer c " +
" inner join orders o " +
" on c.cust_id = o.cust_id"
);
query.addRoot( "c", Customer.class )
.addPropertyMapping( "id", "cid" )
.addPropertyMapping( "name", "cname" );
query.addFetch( "o", "c", "orders" )
.addPropertyMapping( "id", "oid" )
.addPropertyMapping( "orderNumber", "onum" );
