Query / LocalQuery and number of hits
by Ketill Fenne 13 Mar '15

13 Mar '15

Hi! I am using Query / LocalQuery to loop through the results from a query. For several reasons it would be nice to know the number of hits before/without looping through the results. Is this possible? Kind regards Ketill Fenne

Can you prevent database modification via GUI?
by Amanda Galtman 13 Mar '15

13 Mar '15

Hi, Is there a way to prevent users of the BaseX GUI from modifying databases? It seems that at least some of the database files need to be writable or else you can't open the database. It also seems that the GUI gives you admin permission[1], making it possible for you to drop a database. I've been showing BaseX to more of my colleagues, and I want to protect against inadvertent modification of the databases that we are all sharing. Most of us use the GUI on Windows, and a few of us execute queries in standalone mode on various platforms. A related question is whether it is problematic for one user of the GUI to have a database open (or to be actively running a query) while another user of the GUI is trying to run a query on the same database. Maybe a third user is executing a query in standalone mode at the same time. Assume all the queries are non-updating. The doc about transaction management[2] seems to suggest that you can have an arbitrary number of read transactions on the same database, which I take to mean that the different users will not interfere with each other. Is that correct and, if so, does it depend on a particular BaseX version? Thanks, Amanda [1] http://docs.basex.org/wiki/User_Management [2] http://docs.basex.org/wiki/Transaction_Management

BaseX can't add to database and query in different test
by Jason Ricles 13 Mar '15

13 Mar '15

I am currently using BaseX for an XML database. Each XML file currently has a uuid. So, to avoid adding multiple same files to the database, have made a query that will check to see if the uuid from the file being added is already in the database. However I am not able to query the files that already exist in the database until I either open up the database in the BaseX GUI or have the query statement executed at the same time the file is added. So for example if I ran a test of adding a file to the database and then ran a test to query this file it would be unable to query this file. However If I ran the test to add the file to the database and query in the same test the query would work or if I ran the test to add the file to the database and then ran the BaseX GUI and then ran the query test the query will work correctly. Also if I already add the file to basex don't open up the DB then run to add the file again and check before I add the file the query will not work before but only after the file is added a second time. I am writing my code in java. Does anyone know why this is happening and if there is a solution?

Merging baseX indexes
by Marios Bartzokas 13 Mar '15

13 Mar '15

Hi, I am trying to achieve the following; Have a number of baseX servers each working on a replica of an indexed document. One baseX server will handle concurrent client read queries The rest of the servers will handle concurrent client write queries on their copy of the index. In the end I would like to merge all the indexes. Is there a way to achieve that? Best Regards, Marios

Hi, I am trying to evaluate this expression, it is supposed to give TRUE but, it is giving false. sum((<a>5923.17</a>,<a>5956.29</a>,<a>5989.28</a>)) = <a>17868.74</a> But, for this expression it is giving as expected. sum((<a>5922.78</a>,<a>-5955.78</a>,<a>5988.74</a>)) = <a>5955.74</a> Thanks Ankit

xml serialisation
by Menashè Eliezer 12 Mar '15

12 Mar '15

Hello, I need xquery reply which is composed of multiple values. I've chosen the xml format, but I need also the collection name of each record since I'm searching in multiple collections. However for parsing the entire reply as xml I need to add an arbitrary xml tag to base-uri($x). I couldn't find a way to do it. Any ideas? Background: I've tried first the JSON format as output:method, however it cannot be used for more than one record. I've tried text format, but I need an attribute and I get: @codeListValue cannot be serialised So, xml format provides me the option to query the attribute, even though the reply length is bigger. I'm using BaseX 8 beta. -- With kind regards, Menashè

BaseX in JMeter
by Hans-Juergen Rennau 12 Mar '15

12 Mar '15

Hello everybody, has anybody smuggled BaseX into JMeter, for example creating a JMeter plugin using BaseX? The problem: I would like to transform service responses from JSON to XML in order to apply XPath extractions and assertions. Using BaseX, the transformation could be easily accomplished using json:parse + a little post processing which restores the precise XML representation needed. I suppose that a JMeter plugin might be created which executes the query, but I feel unsure if it is a feasible approach. So should anybody have done something similar - managed to bring BaseX into play in the context of JMeter - it would be kind to share the experience. Cheers,Hans-Jürgen

Error?
by Lars Johnsen 12 Mar '15

12 Mar '15

Hi all I have a database collection which gives a strange error message '[FODC0002] "" (Line 1): Content is not allowed in prolog.' on this query: for $x in collection('samtiden') return doc(document-uri($x)) The results from document-uri($x) are as expected, but doc(document-uri($x)) should return $x - so what can be the cause of the error? The collection was entered in the gui using "skip corrupt files" since some of the files had errors (ended prematurely). But the database and document-uri() works fine for all elements in the database. I need to process the paths for grouping the documents in the collection, so the practical value is a bit more than just trying to compute a unity function!

Database Path preference doesn't persist across sessions (v8.0.1/v8.0.2)
by Amanda Galtman 11 Mar '15

11 Mar '15

Hi, I just started using version 8.0.1 and 8.0.2 after having used version 7.9 for awhile. In some GUI sessions, when I enter a Database Path preference value in the Preferences dialog, the value gets used during that session but does not persist in the next session. The .basex file in my .basexhome directory is not being updated to reflect the value I entered in the dialog. The strange thing is that this might not be the case for every session. My .basex file for version 8.0.1 had a custom value in it, which I know I did not set manually in the .basex file. However, today I cannot get it to reflect any other values that I enter in the GUI. As a workaround, I can manually enter a path on the DBPATH line in my .basex file. But I wanted to report this issue anyway. I am using Windows 7, and the .basex and .basexhome files are in my BaseX installation directory. I would be suspicious about Windows administrator permissions, except that this works fine in BaseX 7.9, where .basex is in an analogous location on my hard drive. Thanks, Amanda

Concurrent handling of reads while ADDing a file
by David Mathei 10 Mar '15

10 Mar '15

Hello BaseX Team, I am loading a big file into BaseX (2.1G) and try to understand the handling of concurrent reads during that process. The size does only matter in so far, as loading seems to block reading for an extended amount of time. I observe that I can not read the collection I'm loading into nor any other collection under the same server. When I use another server process on a different port to write to the target collection I can read other collections without delay, the collection I'm loading into is (obviously) blocked by the upd.basex flag. Is there no parallelisation involved that would separate reading from writing processes, or does that only come into play for xquery updates that run under the transaction module? My PARALLEL setting is at the default of 8 and I'm on version 8.0.1. And I apologise already if I missed some obvious configuration... Thanks to everyone involved in this project! David Mathei

Hi, I am using BaseX 8.0.1 version. I am using basex in in-memory embedded mode. I am running a program in Java. My Query execution is taking almost two second, out of which binding Iter to the QueryExecuter is taking almost a second. If i can reduce the binding time, It would boost performance significantly. What step should i take to reduce the same. let me know, What other details you would like to have from me. Thanks

Comparing NxDs
by Mansi 03 Mar '15

03 Mar '15

Hello, I am a happy BaseX user. Currently I am trying to help other teams to find right solution to their data mining from huge xml data store. They are going after postgre and probably even db2. Nor that I have any influence over their decision, but I would like to alert them about something obvious. I just wanted to have some comments from experts here, to give me guidance on what is a major different between these relational DBs supporting native xml storages as compared to BaseX or whatever. I know postgre doesn't support xquery, but db2 does. As you all are aware, our queries won't be complicated probably even xpath might work, just amount of data would be huge. We won't even care hugely about the time taken to return results as long as it's not days. Please advice, - Mansi

Small detail
by France Baril 03 Mar '15

03 Mar '15

Hi, Is it possible to add the name of the DB to this message: [XUDY0016] Document can only be replaced once: menu/app-help-wirelessdisplay.xml. We have 1 DB for each of our 32 languages and we batch process. Since all updates are done by baseX at then end, we can't just get the language from a trace in the loop that goes through languages. Thank you! -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Invoking database update from RESTXQ
by Lars Johnsen 03 Mar '15

03 Mar '15

Hello all I was wondering how to perform database updating, like db:add, in RESTXQ, since the adding and updating functions throw errors when invoked inside functions defined in RESTXQ-modules. Have been trying to use the forward mechanism, transferring the data to a script without functions, with no success. Best, Lars G Johnsen

Potential bug thrown in 'out:format' when argument is an empty sequence
by Seenivasan Gunabalan 02 Mar '15

Hi all, Executing, out:format("hello %s", ()) throws Potential bug error. It is clear that 'out:format' function expects an argument of type item(), but this error seems scary :) Error: Improper use?

Index for multiple dbs
by Marco Lettere 01 Mar '15

01 Mar '15

Hi all, here a question for the weekend ... ;-) The following query performs perfectly exploiting the attribute index: for $d in collection("db") where $d//*:item/@id = '2015000000016940' return $d Why does this not? ("db") ! (for $d in collection(.) where $d//*:item/@id = '2015000000016940' return $d ) In our use case we'd like to have a list of dbs to query on and the list can grow over time so we would not like to change the code by replicating the queries every time a db is added. What is the way out? Thanks, Marco.

LocalSession delete document - No database opened
by Ketill Fenne 27 Feb '15

27 Feb '15

Hi! I am trying to delete a specific document from a database called Users, but get the error "org.basex.core.BaseXException; No database opened" The code is (input name is the document name): Context context = new Context(); LocalSession session = new LocalSession(context); try { new Open("Users").execute(context); session.execute("delete " + name); } catch (Exception e) { e.printStackTrace(); // let the caller handle exception throw e; } Do I need to open the database through the session? Haven't found out how.... BR Ketill Fenne

Re: [basex-talk] Executing Xquery update from java - hangs
by Christian Grün 26 Feb '15

26 Feb '15

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.
