Lukas Kahwe Smith updated JCR-3089:
-----------------------------------
Description:
see the following thread for details:
http://www.mail-archive.com/[email protected]/msg17975.html
assuming a data structure as follows:
/foo [nt:unstructured]
/foo/bar [nt:unstructured]
/foo/bar@lala = huii (lala is string property of bar)
/ding [nt:unstructured]
/ding@dong = ##barUUID### (dong is a property of type "Reference")
then the following code will throw an exception:
DavexClient Client = new DavexClient(url);
Repository repo = Client.getRepository();
Credentials sc = new SimpleCredentials("admin","admin".toCharArray());
Session s = repo.login(sc,workspace);
QueryManager qm = s.getWorkspace().getQueryManager();
String sql = "SELECT data.* FROM [nt:unstructured] AS data WHERE data.lala=
'huii'";
sql = "SELECT * FROM [nt:unstructured] AS data INNER JOIN [nt:unstructured] AS
referring ON referring.[dong] = data.[jcr:uuid] WHERE data.lala = 'huii'";
sql = "SELECT * FROM [nt:unstructured] AS data INNER JOIN [nt:unstructured] AS
referring ON ISDESCENDANTNODE(data, referring) WHERE data.lala = 'huii'";
Query query = qm.createQuery(sql, Query.JCR_SQL2);
QueryResult qr = query.execute();
The first query works just fine and I can iterate over the result. Neither the
second nor the third query works.
In both cases I end up with a javax.jcr.RepositoryException. Note the exception
only happens if the query returns results. Aka a join will work just fine if it
matches no rows.
