Query not returning a result though data is in database

In a Spring MVC application using Hibernate and jpa, the following jpa query is throwing a no result error, even when I have confirmed that there is a result in the DrugWords table and a set of rxcui values for the chosen DrugWord in the rxnconsojunction table:

@SuppressWarnings("unchecked")
public DrugWord findDrugWord(String wrd) {
    System.out.println("..... wrd is: "+wrd);//prints a value with valid records in database
    Query query = this.em.createQuery("SELECT word FROM DrugWord word left join fetch word.concepts WHERE word.name =:wrd");
    query.setParameter("wrd", wrd);
//        try{
        return (DrugWord) query.getSingleResult();
//          }
//        catch(Exception e){}
//        return new DrugWord();
}

Here is the complete stack trace:

Hibernate: select drugword0_.name as name1_12_0_, drugconcep2_.rxcui as rxcui1_10_1_, concepts1_.word as word1_12_0__, concepts1_.rxcui as rxcui2_13_0__ from drugwords drugword0_ left outer join drugwordsconsoJunction concepts1_ on drugword0_.name=concepts1_.word left outer join drugconcepts drugconcep2_ on concepts1_.rxcui=drugconcep2_.rxcui where drugword0_.name=?

Note

Changing the query to be em.find(DrugWord.class, wrd) identified a different, unrelated error, which I then resolved. Now it is showing that the concepts collection for the selected DrugWord, even though there is data in the underlying table.

The problem might be you forgot to declare @entity on top of entity class or otherwise in configuration hbm2ddl might be create instead of update.
