Question

I am trying to retrieve data from my database with hibernate but it keeps throwing an exception

2012-11-11 11:35:45,943 [main] ERROR
com.storage.hibernate.DatabaseAccessRequestsImpl – there was an error
javax.persistence.PersistenceException:
org.hibernate.exception.SQLGrammarException: could not execute query

@Override
public List<Trade> requestPeriod() {
    List<Trade> trades = null;
    EntityManager manager = emf.createEntityManager();
    Query query = manager.createQuery("from trade"); 
    try{
        trades = query.getResultList();
    }
    catch(PersistenceException e){
        logger.error("there was an error " + e);
    }
    catch(SQLGrammarException e){
        logger.error("there was an error " + e);
    }
    return trades;
}

I am guessing the syntax I am using for select all is incorrect but after looking around I can not see an alternative?

Thanks

Answer 1

It should be "from Trade" (uppercase T) as Trade is the name of the mapped class.
