Subject [jira] Created: (CAY-1110) fetchLimit + DistinctResultIterator = fewer rows in the result
Date Tue, 23 Sep 2008 18:43:12 GMT
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


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)
