Hi Ketill,

I'm cc'ing this back to the mailing list, as it may also be of interest for other users.

Would you advice against mixing different "connection methods" to the database(s) in the same application? (Queries through XQJ, updates via QueryProcessor)

Using a single API will usually cause you less headache in the middle or long term, but it may be fine to simply try out things. If you create QueryProcessor instances, no problems are to be expected as long as you dont't need to run concurrent queries. You could also work with LocalSession instances, which will be more stable in the long run. The (Local|Client)Session API could be further extended to meet more requirements, depending on the feedback we get.

Hope this helps, Christian

Hi Ketill,

Welcome to our list.

XQJ was written to be compliant with XQuery 1.0, so it may well be that the db:output extension cannot be used with our (well, Charles Foster's) implementation of XQJ (yet). Have you tried to set the MIXUPDATES flag to true instead?

All the best, Christian

Hi!

I am executing all Xqueries through the same runQuery method in Java, and I am running the latest jar-files (8.0.1):

        XQDataSource ds = new BaseXXQDataSource();
        xqc = ds.getConnection();
        XQExpression xqe = xqc.createExpression();
        rs = xqe.executeQuery(query);

The query is (in this case): for $doc in (collection('Users/customer_1'))/* return (replace value of node $doc/@name with ("My new customer name"))

The update works fine in BaseX Gui, and I suspect the problem is that it does not return anything, and my code expects XQResultSequence. I have tried adding db:output to return part of the query with no luck. Do you have any suggestions?

Kind regards Ketill Fenne
