Is there a way to get the (to-be-generated) SQL from a Hibernate Criteria
?
Ideally, I would have something like:
Criteria criteria = session.createCriteria(Operator.class);
... build up the criteria ...
... and then do something like ...
String sql = criteria.toSql()
(But this of course does not exist)
The idea would then be to use the SQL as part of a huge 'MINUS' query (I need to find the differences between 2 identical schemas - identical in structure, not in data - and the MINUS is not supported by Hibernate)
(BTW I know I can check the SQL from the log files)
Here's "another" way to get the SQL :
CriteriaImpl criteriaImpl = (CriteriaImpl)criteria;
SessionImplementor session = criteriaImpl.getSession();
SessionFactoryImplementor factory = session.getFactory();
CriteriaQueryTranslator translator=new CriteriaQueryTranslator(factory,criteriaImpl,criteriaImpl.getEntityOrClassName(),CriteriaQueryTranslator.ROOT_SQL_ALIAS);
String[] implementors = factory.getImplementors( criteriaImpl.getEntityOrClassName() );
CriteriaJoinWalker walker = new CriteriaJoinWalker((OuterJoinLoadable)factory.getEntityPersister(implementors[0]),
translator,
factory,
criteriaImpl,
criteriaImpl.getEntityOrClassName(),
session.getLoadQueryInfluencers() );
String sql=walker.getSQLString();
