Re: [eclipselink-users] Query with enum KEY 
Hi,
Try setting persistence property eclipselink.logging.level=FINER and inspect the SQL. Is the SQL what you expect? If you run it separately do you get the results you expect?

Hello,
I am having trouble querying enumerated Map attributes using EclipseLink 2.1. Here is some detail regarding to mapping 


@ElementCollection
@CollectionTable(name = "MAP_TABLE", joinColumns = @JoinColumn(name = "ME_ID")) 

@MapKeyEnumerated(EnumType./STRING/)

@MapKeyColumn(name = "KEY_NAME")

@Column(name = "KEY_VALUE")

*private* Map<MyCustomEnumType, String> mapAttr;
When I executed the following query, I don’t get any exception but there is no record being returned even though there are data in the database that fits the criteria
Query q = em.createQuery("select KEY(p) from myObject me join me.mapAttr p where KEY(p) = :param1"); 

  q.setParameter("param1", MyCustomEnumType.enum1);

  _List_ l = q.getResultList();
System./out/.println("Size:::" + l.size() + " --- Value::" + l.toString());
However, if I persist EnumType.ORDINAL instead EnumType.STRING in the @MapKeyEnumerated then the same query works fine - returns the right set of data back. I have tried to use name() method to make sure that a STRING value of enum would use inside the query but I have exceptions. Do you have any idea what I am missing here? 


Thanks

Aysun
