Question

I’m responsible on porting existing project from Oracle to MSSQL, but keeping both functional.
Legacy project uses Hibernate 3.x, but contains some number of sophisticated native queries.
So I would like to know which dialect used.

Answer 1

At last I’ve found the way – but it is specific for Hibernate.

//take from current EntityManager current DB Session
Session session = (Session) em.getDelegate();
//Hibernate's SessionFactoryImpl has property 'getDialect', to
//access this I'm using property accessor:
Object dialect = 
       org.apache.commons.beanutils.PropertyUtils.getProperty(
          session.getSessionFactory(), "dialect");
//now this object can be casted to readable string:
if( dialect.toString().contains("Oracle")){
   ....
