Description

Joint prefetches do not work on Oracle(when at least one column name in root and prefetched tables has the same name (this is the most common case - source and target join columns have the same name). Example of invalid SQL:

select * from ( select tid.*, ROWNUM rnum from (SELECT DISTINCT t0.DOCID, t0.DOCTYPEID, t0.DOCDATE, t0.TIMESTAMP, t0.DOCDATEBEGIN, t0.DOCDESC, t0.DOCNAME, t0.DOCEND, t0.DOCDATEEND, t0.DOCSTATUSID, t0.LABELID, t0.DOCNUMBER, t0.DELETED, t0.DBUSER, t0.FOLDERID, t0.DOCDATEAGREE, t1.DBUSER, t1.DELETED, t1.TIMESTAMP, t1.CUSTOMERID, t1.DOCID, t1.KCADOCID, t1.KCADOCTYPEID, t1.KCAID, t1.ORGSID FROM DOC t0 LEFT JOIN KCA_DOC t1 ON (t0.DOCID = t1.DOCID) WHERE t0.DOCTYPEID = ?) tid where ROWNUM <=30) where rnum > 0
