> Incorrect query results from TDB with FILTER NOT EXISTS containing a filter
> ---------------------------------------------------------------------------
>
> Key: JENA-430
> URL: https://issues.apache.org/jira/browse/JENA-430
> Project: Apache Jena
> Issue Type: Bug
> Components: TDB
> Affects Versions: TDB 0.9.4
> Environment: Windows 8
> Reporter: Brian McBride
> Attachments: Main.java
>
>
> TDB is producing incorrect results processing queries containing FILTER NOT
> EXISTS clauses with an inner filter, such as
> PREFIX : <http://example.com/>
> SELECT * WHERE {
> ?x :p ?n
> FILTER NOT EXISTS {
> ?x :q ?m .
> FILTER(?n = ?m)
> }
> }
> an example taken from the spec. In this case it produces no results when it
> should produce one.
> I'll attach a test case in moment - which produces the correct result when
> the query is run on a memory model and incorrect one (no results) when run on
> TDB.
