[MonetDB-users] XQuery API and XLink/XUpdate support
by Alexandra Mart�nez 27 Jun '24

27 Jun '24

Hello all, I was wondering if there is any documentation about the API for XQuery (i.e., how to write xqueries from a Java program). Also, I am interested in using some features of XLink and XUpdate on top of my XML database. Is support for any of these in progress? Thanks in advance, Alexandra ______________________________________________________ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/

[MonetDB-users] Different results with same query
by Matthieu Guamis 08 Nov '12

08 Nov '12

Hello, Running the same query on the same data leeds to different results between postgresql and monetdb. I have not been able to get a simple example to reproduce the problem. So here is what I observe: the query: select temps_mois.rfoperdmo as c1, sum((case when dwhinv.dwhinv___rfodomide = 'RH' and dwhinv.dwhinv___rfoindide = 'tech_rh_effectif_rem_reel' then dwhinv.dwhinvqte else 0 end)) as m0 from rfoper_temps_mois as temps_mois, dwhinv as dwhinv, rfovsn as rfovsn_0, rrhamv as rrhamv_1, rrhcov as rrhcov_2, rfoadv as rfoadv_3 where temps_mois.rfoper___rforefide = 'HPLUS' and dwhinv.dwhinv___rforefide = 'HPLUS' and dwhinv.dwhinv___rfodomide = 'RH' and dwhinv.dwhinv___rfoindide = 'tech_rh_effectif_rem_reel' and dwhinv.dwhinvdtd = temps_mois.rfoperdtd and temps_mois.rfoperyea = '2011' and rfovsn___rforefide = 'HPLUS' and dwhinv.dwhinv___rfovsnide = rfovsn_0.rfovsnide and rfovsn_0.rfovsnide = '201111_reel' and rrhamv_1.rrhamv___rrhvemide='GRACOR' AND rrhamv_1.rrhamvrvs=1 AND rrhamv_1.rrhamv___rforefide= 'HPLUS' and dwhinv.dwhinv___rrhempide = rrhamv_1.rrhamvinf and rrhamv_1.rrhamvsup = 'CEMP' and rrhcov_2.rrhcov___rrhvcoide='CONTRATS' AND rrhcov_2.rrhcovrvs=1 AND rrhcov_2.rrhcov___rforefide= 'HPLUS' and dwhinv.dwhinv___rrhcntide = rrhcov_2.rrhcovinf and rrhcov_2.rrhcovsup = 'CONTRATS' and rfoadv_3.rfoadv___rfovdeide='STRC' AND rfoadv_3.rfoadvrvs=1 AND rfoadv_3.rfoadv___rforefide= 'HPLUS' and dwhinv.dwhinv_p2rfodstide = rfoadv_3.rfoadvinf and rfoadv_3.rfoadvsup = 'HPLUS' group by c1 order by c1 Postgresql result: c1 | m0 ----+----------------- 01 | 7111.5376967750 02 | 7100.9108821426 03 | 7150.2597967742 04 | 7151.4283666667 05 | 7109.1641451610 06 | 6976.2108421239 07 | 6329.7404193564 08 | 6302.9823032247 09 | 6426.9459633351 10 | 6519.6889580648 11 | 6549.5235033402 12 | 6492.5477161292 (12 lignes) Monetdb result: +------+----------------------+ | c1 | m0 | +======+======================+ | 12 | 1.000000 | | 11 | 1.000000 | | 10 | 2.000000 | | 09 | 0.366667 | | 08 | 1.000000 | | 07 | 1.000000 | | 06 | 1.000000 | | 05 | 3.000000 | | 04 | 4.000000 | | 03 | 15.000000 | | 02 | 9.964286 | | 01 | 1.000000 | +------+----------------------+ 12 tuples (212.346ms) As you see, all "m0" values are very different. I have no idea of what is causing this but if I modify the query in order to simplify the CASE...WHEN...ELSE part of the select, it produce the expected result: replacing sum((case when dwhinv.dwhinv___rfodomide = 'RH' and dwhinv.dwhinv___rfoindide = 'tech_rh_effectif_rem_reel' then dwhinv.dwhinvqte else 0 end)) as m0 by sum((case when dwhinv.dwhinv___rfoindide = 'tech_rh_effectif_rem_reel' then dwhinv.dwhinvqte else 0 end)) as m0 Its not exactly the same query but it must leeds to the same result due to my test datas (its the case in postgres) I join to this email two files with the TRACES, respectively for the request with bad/correct result (ko.txt/ok.txt) Config: Ubuntu Server 11.04 x64 MonetDB v11.7.9 (Dec2011-SP2), MonetDB Database Server v1.6 (Dec2011-SP2), MonetDB Database Server Toolkit v1.0 (Dec2011-SP2) Thank you very much for your help!! -- *Matthieu Guamis* *Logo Axège <http://www.axege.com/>* /Axège// 23,rue Saint-Simon 63000 Clermont-Ferrand/ Tél: +33 (0)4 63 05 95 40 Fax: +33 (0)4.73.70.65.29 Email: matthieu.guamis(a)axege.com <mailto:matthieu.guamis@axege.com>

[MonetDB-users] MonetDB Python client
by Alexey Mints 05 Jul '12

05 Jul '12

Hello! I had a problem with Python client hanging up if MonetDB connection was closed unexpectedly. This happened for example, when I have passed a request that caused "ERROR = !Connection terminated" in mclient. Such things should not occur in a ideal life, but they do =( The problem was that socket.recv cannot handle this situation properly. The solution is to use select.select statement. I attach the diff to mapi2.py file that solves the problem. Regards, Alexey

I performed the following operations sequentially. Please look at the result when I use SUM. Sum values are incorrect. They should be 60/600/6000/60000.AVG returns correct values though.
