Here is an overview of the issue:
---------------------------------------------------------------------
Key: HB-298
Summary: Mapping of Oracle`s XMLType datatype into class
Type: Improvement
Status: Unassigned
Priority: Major
Project: Hibernate2
Versions:
2.1
Assignee:
Reporter: Marc Villeneuve
Created: Thu, 28 Aug 2003 10:34 AM
Updated: Thu, 28 Aug 2003 10:34 AM
Environment: Oracle 9ir2, patchset 9.2.0.3. and Hibernate 2.x
Description:
Hi,
There is no simple way to currently map data provided from an XMLType (xml document) into a class without rewritting a serious amount of code in EntityPersister ( please tell me if I am wrong). Extraction requires using xpath through proprietary functions (extract and extracValue).
The new formula attribute might have improve the current situation since it is now possible to call for the function, but the Oracle syntax looks more like "extractValue( alias.column, xpathExpression)" and "alias.extractValue( alias.column, xpathExpression)" as generated is invalid.
If this can be achieved otherwise (by sending a direct SQL query ?), please be nice enough to point me in the right direction.
Thanks
