  • Recursive calls in Pentaho Data Integration

    - by davek
    Is it possible for a step or transformation in Pentaho Data Integration to call itself, passing the results of the previous call as parameters/variables? My first thought was to create a loop in a transformation, but they don't seem to be allowed...

  • Jquery: Datalink - Data linking

    - by Pickels
    I was trying out the Jquery Data linking proposal from Microsoft and noticed something strange. My objects get this extra property and I was wondering what the reason for that is. I first thought it was a mistake I made but I noticed their demo page does the same thing This is the json result of my objects: [{ "propertyName":"ProductNamese", "controlType":"Text", "jQuery1274021322131":6 }, { "propertyName":"Price", "controlType":"Number", "jQuery1274021322131":9 }, { "propertyName":"Description", "controlType":"TextArea", "jQuery1274021322131":12 } ] The property I am talking about is "jQuery1274021322131".

  • Skip List vs. Binary Tree

    - by Claudiu
    I recently came across the data structure known as a Skip list. They seem to have very similar behavior to a binary search tree... my question is - why would you ever want to use a skip list over a binary search tree?

  • SQLServer:Namespaces preventing access to query data

    - by Brian
    Hi A beginners question, hopefully easily answered. I've got an xml file I want to load into SQLServer 2008 and extract the useful informaiton. I'm starting simple and just trying to extract the name (\gpx\name). The code I have is: DECLARE @x xml; SELECT @x = xCol.BulkColumn FROM OPENROWSET (BULK 'C:\Data\EM.gpx', SINGLE_BLOB) AS xCol; -- confirm the xml data is in @x select @x as XML_Data -- try and get the name of the gpx section SELECT c.value('name[1]', 'varchar(200)') as Name from @x.nodes('gpx') x(c) Below is a heavily shortened version of the xml file: <?xml version="1.0" encoding="utf-8"?> <gpx xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" version="1.0" creator="Groundspeak Pocket Query" xsi:schemaLocation="http://www.topografix.com/GPX/1/0 http://www.topografix.com/GPX/1/0/gpx.xsd http://www.groundspeak.com/cache/1/0 http://www.groundspeak.com/cache/1/0/cache.xsd" xmlns="http://www.topografix.com/GPX/1/0"> <name>EM</name> <desc>Geocache file generated by Groundspeak</desc> <author>Groundspeak</author> <email>[email protected]</email> <time>2010-03-24T14:01:36.4931342Z</time> <keywords>cache, geocache, groundspeak</keywords> <wpt lat="51.2586" lon="-2.213067"> <time>2008-03-30T07:00:00Z</time> <name>GC1APHM</name> <desc>Sandman's Noble Hoard by Sandman1973, Unknown Cache (2/3)</desc> <groundspeak:cache id="832000" available="True" archived="False" xmlns:groundspeak="http://www.groundspeak.com/cache/1/0"> <groundspeak:name>Sandman's Noble Hoard</groundspeak:name> <groundspeak:placed_by>Sandman1973</groundspeak:placed_by> </groundspeak:cache> </wpt> </gpx> If the first two lines are replaced with just: <gpx> the above example works correctly, however I then can't access groundspeak:name (/gpx/wpt/groundspeak:cache/groundspeak:name), so my guess its a problem with the namespace. Any help would be appriciated.

  • (interactive) graph as in graph theory on a web page ?

    - by LB
    Hi, I have to integrate a graph with nodes and edges on a web page. Ideally, i would like to be able to interact with it (like moving the nodes around). Actually, i'm beginning by representing trees, so i would appreciate to be able to collapse subtrees. How can I do that ? I was considering google-visualization api but i wasn't able to find the kind of visualization i'm looking for (org chart doesn't allow to have multiple fathers, if i understood well) I've got no idea of the kind of technology so my tagging may not be really accurate :-). thanks

  • Django - testing using large tables of static data

    - by Michael B
    I am using "manage.py test" along with a JSON fixture I created using using 'dumpdata' My problem is that several of the tables in the fixture are very large (for example one containing the names of all cities in the US) which makes running a test incredibly slow. Seeing as several of these tables are never modified by the program (eg - the city names will never need to be modified), it doesn't make much sense to create and tear down these tables for every test run. Is there a better way to be testing this code using this kind of data?
