I am @ Oracle 12.1.0.2.0

> It seems that is not easy to reproduce this issue (see
[https://asktom.oracle.com/pls/apex/asktom.search?tag=duplicate-columns-
in-oracle-query-using-row-limiting-clause AskTom]). It works in both cases
i.e. when identically named columns are in the
[https://code.djangoproject.com/attachment/ticket/29630/29630.diff same
table] or in
[https://code.djangoproject.com/attachment/ticket/29630/29630_different_tables.diff
different tables], e.g.
>
> {{{
> SELECT
> "QUERIES_TAG"."NAME",
> "QUERIES_NAMEDCATEGORY"."NAME"
> FROM
> "QUERIES_TAG"
> LEFT OUTER JOIN "QUERIES_NAMEDCATEGORY" ON
> ("QUERIES_TAG"."CATEGORY_ID" =
"QUERIES_NAMEDCATEGORY"."DUMBCATEGORY_PTR_ID")
> ORDER BY "QUERIES_TAG"."NAME" ASC
> FETCH FIRST 2 ROWS ONLY
> }}}
