Why will a query work in SQL Developer but not in Apex?

Question

Here's a good one. I created a dynamic LOV with the following query.
select
e.DESCR d,
ee.ENTRD_EVNT_SK r
from
PT_EVNT_IN_DIV eid,
PT_ENTRD_EVNT ee,
PT_EVNT e
where ee.PGNT_SK = :PGNT_SK
and ee.CNTSNT_SK = :CNTSNT_SK
and ee.EVNT_IN_DIV_SK = eid.EVNT_IN_DIV_SK
and eid.EVNT_SK = e.EVNT_SK
and ee.ENTRD_EVNT_SK not in
(select js.ENTRD_EVNT_SK
from PT_JDG_SCR js
where js.JDG_SK = :JDG_SK
and js.PGNT_SK = :ai_pgnt_sk
and js.CNTSNT_SK = :CNTSNT_SK)
order by 1
The query works fine in SQL Developer, but Apex gives the following error when compiling it in the LOV editor.
"1 error has occurred
- LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query."
I tried rearranging the entries in the From clause, but that didn't do any good.
Do you see what I can do to make Apex accept it?
Thanks,

The column named ENTRD_EVNT_SK is used twice in a select. Once in the main select and once in the inline query.
The validation maybe choking on that.
Try giving the column in the inline query an alias and see if that helps.
