Loiko Dima updated CAY-1110:
----------------------------
Attachment: limit.txt
> fetchLimit + DistinctResultIterator = fewer rows in the result
> --------------------------------------------------------------
>
> Key: CAY-1110
> URL: https://issues.apache.org/cayenne/browse/CAY-1110
> Project: Cayenne
> Issue Type: Bug
> Components: Cayenne Core Library
> Affects Versions: 3.0
> Reporter: Andrus Adamchik
> Assignee: Andrus Adamchik
> Fix For: 3.0
>
> Attachments: limit.txt, limitIterator.txt, test_v_2.txt

> I don't have a test case yet, but I noticed in a SelectQuery with implicit
> DISTINCT (due to a qualifier on to-many), if the root entity has columns that
> force Cayenne into outside-of-db distinct check (e.g. CLOB columns), I am
> getting fewer results than the fetch limit. This is due to fetch limit being
> applied inside the inner result iterator (JDBCResultIterator) not the outer
> filtering iterator (DistinctResultIterator)
