0015556: OBCriteria is not able to filter Oracle's CLOB datatype

Description

In Oracle trying to use OBCriteria to filter a CLOB datatype property, the following error is raised:

ORA-00932: inconsistent datatypes: expected - got CLOB

The problem is Oracle doesn't accept this syntax:

select * from myTable where ClobColumn = 'anyText';

It requires this other one instead (works in Oracle 11g, needs to be tested in 9g):

select * from myTable where to_char(ClobColumn) = 'anyText';

Steps To Reproduce

This snippet taken from org.openbravo.erpCommon.modules.ModuleReferenceDataOrgTree class before fixing issue 0015555 fails:

OBCriteria<ADOrgModule> adOrgModCriteria = OBDal.getInstance().createCriteria(
          ADOrgModule.class);
OBDal.getInstance()
          .get(Organization.class, strOrg)));
      adOrgModCriteria.add(Expression.eq(ADOrgModule.PROPERTY_CHECKSUM, checksum));
adOrgModCriteria.list();

Proposed Solution

Is this a DAL issue, or is it in the Hibernate side?

Workaround:

Instead of using OBCriteria to filter CLOB columns, use OBQuery adding the to_char DB function:

String whereClause = "as m where m.module.id = :module and m.client.id=:client and m.organization.id=:org and to_char(m.checksum)=:checksum";
OBQuery<ADOrgModule> cOrgModule = OBDal.getInstance().createQuery(ADOrgModule.class,
whereClause);
