ORA-00911: invalid character when field begins with underscore
--------------------------------------------------------------
Key: HHH-2022
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2022
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.0.5, 3.1.3, 3.2.0.cr3
Environment: Hibernate 3.1.3
Oracle 10.2.0.1
Reporter: Jerry Cattell
Priority: Minor
Attachments: InvalidCharacterErrorCase.java, SimpleObject.hbm.xml, SimpleObject.java
Hibernate is generating invalid SQL (for Oracle) for collections that are stored in fields with names that start with underscores.
In this SQL:
Hibernate: select _tags0_.SIMPLE_OBJECT_ID as SIMPLE1_0_, _tags0_.TAG as TAG0_ from SIMPLE_OBJECT_TAG _tags0_ where _tags0_.SIMPLE_OBJECT_ID=?
an alias called "_tags0_" is created for the collection table. Unfortunately, Oracle does not allow non-alphabetic characters for the first character in an alias.
Here's the stacktrace:
Hibernate: select _tags0_.SIMPLE_OBJECT_ID as SIMPLE1_0_, _tags0_.TAG as TAG0_ from SIMPLE_OBJECT_TAG _tags0_ where _tags0_.SIMPLE_OBJECT_ID=?

I have attached a test case that causes this error.
After a little bit of research, it appears that a change to StringHelper.generateAlias(String description, int unique) (or StringHelper.generateAliasRoot(String description)) to remove all characters up to the first alphabetic character would solve this problem.

[Hibernate-JIRA] Created: (HHH-2019) Provide a way to unset properties, and/or provide a 'none' option for hbm2ddl.auto
by Dave E Martin (JIRA)
Provide a way to unset properties, and/or provide a 'none' option for hbm2ddl.auto
----------------------------------------------------------------------------------
Key: HHH-2019
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2019
Project: Hibernate3
Type: Improvement
Environment: hibernate / annotations / hibernate.properties
Reporter: Dave E Martin
Priority: Minor
It may occasionally be desirable to programmatically get rid of or override a property value, this is generally allowed for by the .setProperty method, however:
Once hbm2ddl.auto is set to something, there is no way to unset it, or set it to a value which would be equivalent to its being unset (or its undocumented). There is no remove or unset, or deleteProperty, and also setting it to null does not work.
Due to issues such as HHH-2018, it may be necessary to programmatically 'get rid of' hbm2ddl.auto even if the end user (or some other mechanism) has specified a value for it in an external hibernate.properties file (or other method of setting hibernate properties).

[Hibernate-JIRA] Created: (HHH-2034) Potential ClassCastException in catch block in NullableType
by Galen Palmer (JIRA)
Potential ClassCastException in catch block in NullableType
-----------------------------------------------------------
Key: HHH-2034
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2034
Project: Hibernate3
Type: Improvement
Components: core
Versions: 3.1.3
Environment: Hibernate 3.1.3
Reporter: Galen Palmer
Priority: Minor
It is possible to throw an exception from within the catch block of NullableType.nullSafeSet() since the toString(value) method calls in many cases (e.g. StringType) simply result in a cast of return (String)value. This may mask the underlying problem for the users.
A proposed solution would be to replace the call in the catch blog of toString(value) with a reference to value. For example:
line 87:
log().info( "could not bind value '" + value + "' to parameter: " + index + "; " + re.getMessage() );
and line 91:
log().info( "could not bind value '" + value + "' to parameter: " + index + "; " + se.getMessage() );
This change would prevent the catch block from throwing the exception.

if (sessionFactory == null)
sessionFactory = // by look up

return sessionFactory.getCurrentSession();
}
I get following excpetion
