Subject [jira] [Commented] (JCR-3089) javax.jcr.RepositoryException when a JOIN SQL2 query is send via Davex and has results
Date Tue, 04 Oct 2011 14:12:34 GMT

    [ https://issues.apache.org/jira/browse/JCR-3089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13120149#comment-13120149
] 

Alex Parvulescu commented on JCR-3089:
--------------------------------------

yes, sure. I've added it to the code.

@Christian, I didn't check the results either ;) if the queries stop working, somebody will
say something probably.

thanks Angela for keeping an eye out!

if all is ok, I'll commit the patch directly. I don't see a need for a v3.

> 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.
