> DCDTO is the super class while DDTO and CDTO are its child classes 
> suppose we do 
> session.get(DDTO.class, ID);
> the clause " where accountType='D'  "   is not happening
> as a result if the ID provided is the Pkey of CDTO entry (accountType='C')  it still gives the result 
> But if we execute the HQL query----"from DDTO where ID=?" the where clause (" where accountType='D'  " ) gets added!!!
