  • Can someone explain how OpenXML works(in this SP)?

    - by chobo2
    Hi I am looking at this tutorial and it confuses me as I don't get the SP CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc First I am using SQL 2005 and do I need to install something on the server to get OPENXML to work? Next I don't get what these statements do // not sure what @hDoc is for and why it is an int DECLARE @hDoc int // don't get what this is and where the output is. exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData // don't get why it is "XMLProdTable" and if it always has to be like this SELECT XMLProdTable.NAME // pretty muct don't get anything what is happening after OPENXML FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable // Don't know what this is really executing EXEC sp_xml_removedocument @hDoc Thanks

  • Hibernate: How do I link a subclass to its superclass?

    - by Markus
    Hey there! I'm having a little problem setting up my webshop project. Thing is, I have a User() superclass and two subclasses, PrivateUser and BusinessUser. Now, I'm not quite sure how to get my head around storing this relationship via hibernate. For the purpose of this question, the User() class contains only one field: String address; the PrivateUser contains: String firstName; and the BusinessUser contains: String CompanyName; Each field has its getter and setter. As is right now, I would only store and be able to get firstName and companyName. When I fetch a user from my DB using Hibernate I would get a PrivateUser/BusinessUser with a null address. Bottom line is, could someone point me towards a useful tutorial or better yet show a similar example code? Thanks!

  • Table and Column names causing problems

    - by craig
    I have an issue when the T4 linq templates generate the classes for my MySql db using subsonic 3. It looks like one of our table names "operator" is causing problems in the Context.cs generated class. In the following line of code in Context.cs Visual Studio sees <operator> as a c# operator and generates a compilation error of "Type expected" public Query<operator> operators { get; set; } Is there anyway I can work around this without having to rename my database table and column names? For example hard coding something in Settings.ttinclude to use or map different names to specific db tables and columns?

  • Lucene.NET faceted search.

    - by Paul Knopf
    I found a great tutorial on performing a faceted search. http://www.devatwork.nl/articles/lucenenet/faceted-search-and-drill-down-lucenenet/ This article does not explain how to retrieve the narrowed available attributes to filter from (for further drill down). Lets say I am looking for planners that are red. When I perform the faceted search, I want to return all available attributes to filter from that are red. Then when I add a "weekly format" filter, I want the attribute list to get even smaller, containing only filters available for the segmented group.

  • How many repositories should I use to maintain my scripts under version control?

    - by romandas
    I mainly code small programs for myself, but recently, I've been starting to code for my peers on my team. To that end, I've started using a Mercurial repository to maintain my code in some form of version control (specifically, Tortoise-Hg on Windows). I have many small scripts, each in their own directory, all under one repository. However, while reading Joel's Hg Tutorial, I tried cloning a directory for one of my bigger scripts to create a "stable" version and found I couldn't do it because the directory wasn't itself a repository. So, I assume (and please correct me if I'm mistaken) that in order to use cloning properly, I'd have to create a repository for each script/directory. But.. would that be a "good idea" or a future maintenance nightmare waiting to happen? Succinctly, do I keep all my (unrelated) scripts in one repository, or should I create a repository for each? Or some unknown third option?

  • Lexical and dynamic scoping in Mathematica: Local variables with Module, With, and Block

    - by dreeves
    The following code returns 14 as you'd expect: Block[{expr}, expr = 2 z; f[z_] = expr; f[7]] But if you change that Block to a Module then it returns 2*z. It seems to not matter what other variables besides expr you localize. I thought I understood Module, Block, and With in Mathematica but I can't explain the difference in behavior between Module and Block in this example.

  • Demystifying gcc under lpthreads

    - by Berkay
    in these i'm playing with thread library and trying to implement some functions. One of the tutorial says that to run the program use : gcc -lpthread -lrt -lc -lm project1.c scheduler.c -o out first of all i need deep understanding of what is gcc doing in each line, lpthread is used for what? what are the contributions of lrt -lc -lm ? project1.c and scheduler.c is compiled together so what should i understand? i checked the code and any of them not included in project1.c or scheduler.c. as an output clearly it gives "out". secondly the author states that to run the program you have to use ./out number filename (For example, ./out 2 sample.txt) To make these clear as far as i understand the main function gets number and sample.txt as an input.(?) thanks for your answers and making me clear.

  • Idiots guide to app engine and memcache

    - by Gareth Simpson
    I am struggling to find a good tutorial or best practices document for the use of memcache in app engine. I'm pretty happy with it on the level presented in the docs. Get an object by ID, checking memcache first, but I'm unclear on things like: If you cache a query, is there an accepted method for ensuring that the cache is cleared/updated when an object stored in that query is updated. What are the effects of using ReferenceProperties ? If a cache a Foo object with a Bar reference. Is my foo.bar in memcache too and in need of clearing down if it gets updated from some other part of my application. I don't expect answers to this here (unless you are feeling particularly generous!), but pointers to things I could read would be very gratefully received.

  • Using attribute text value in AngularJS directive

    - by C1pher
    Using a YouTube tutorial created by John Lindquist, I was able to create a directive using a template. See fiddle: http://jsfiddle.net/37PSs/ Now, I want to use the value of the attribute as a variable to a function call. Something like this: html: <hello-world name="World"></hello-world> javascript - directive: template: '<span>myFunction({{name}})</span>' javascript - myFunction(theirName): return ("Hello, " + String(theirName) + "!"); The closest I've been able to get is passing an [object Window] to my function.

  • Trying to compile MobileSubstrate addon - Undefined symbol

    - by eWolf
    Hi! I went through this tutorial to create a MobileSubstrate addon. I could compile the example hook without errors. But as soon as I add #import <SpringBoard/SBAwayController.h> in ExampleHookProtocol.h and SBAwayController *awayController = [SBAwayController sharedAwayController]; in ExampleHookLibrary.mm (as the first line of the __$ExampleHook_AppIcon_Launch function) I get the following error message when attempting to make (triggered by the latter change): Undefined symbols: "_OBJC_CLASS_$_SBAwayController", referenced from: __objc_classrefs__DATA@0 in ExampleHookLibrary.o ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [ExampleHook.dylib] Error 1. The header file for SBAwayController is located in /var/toolchain/sys30/usr/include/SpringBoard, just like SBApplicationIcon.h, which is used by the ExampleHook. I'm compiling on my iPod touch 2G. Can anyone help me? Thanks in advance, Eric

  • Finding parents where child collection does not contain an item with a specific property value

    - by Colin Bowern
    I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

  • Do I always have to provide Tkx's -command argument an anonymous subroutine?

    - by Zaid
    I find it a bit weird that I have to wrap defined subroutines anonymously when specifying the -command argument for Tkx widgets. An excerpt from a TkDocs tutorial demonstrates this: my $cb = $frm->new_ttk__button ( -text => "Calculate", -command => sub {calculate();} ); sub calculate { $meters = int(0.3048*$feet*10000.0+.5)/10000.0 || ''; } Why doesn't it work when I write -command => &calculate() or -command => \&calculate()?

  • Bad interpreter: No such file or directory

    - by user1497462
    I'm working through Michael Hartl's tutorial trying to learn Rails for the first time, and I've run into some issues. I recently reinstalled the whole Rails Installer because I had apparently inadvertently deleted some important files. Now, when I try running a test I get the following error: sh.exe": /c/Program Files (x86)/ruby-1.9.3/bin/bundle: "c:/Program: bad interpre ter: No such file or directory I checked my PATH and attempted to use the solution outlined here: Bundle command not found.

  • What are some best practices for structuring cherrypy apps?

    - by Omega
    I'm writing a cherrypy app and I was wondering what the best way is for structuring my handlers and code for larger applications? I realize assignment is simple trough cherrypy.root, but what are some practices for writing the handlers and assigning them? (Allow me to prove my confusion!) My initial thought is to write a standard handler class that infers a template to run based on the current URL or class/method combination. Then I would assign one instance of that handler multiple times to the path to create pages. I don't see this working however as the recursive references wouldn't work quite right. So, given the fact that I'm already drawing blanks on how my own source code should look, I'd love some pointers and examples! Feel free to ask some detailed questions for me to clarify. While there is plenty of cherrypy tutorial material out there, it tends to only scratch the surface.

  • Ruby on rails link_to syntax

    - by mizipzor
    After following a tutorial Ive found. Im now redoing it again, without the scaffolding part, to learn it better. However, editing my \app\views\home\index.html.erb to contain: <h1>Rails test project</h1> <%= link_to "my blog", posts_path> I get an error: undefined local variable or method `posts_path' for #<ActionView::Base:0x4e1d954> Before I did this, I ran rake db:create, defined a migration class and ran rake db:migrate, everything without a problem. So the database should contain a posts table. But that link_to command cant seem to find posts_path. That variable (or is it even a function?) is probably defined through the scaffold routine. My question now is; how do I do that manually myself, define posts_path?

  • mvc2 validation problem (ambiguous reference between model and models)

    - by ile
    I followed instructions for mvc validation but I can't manage to solve this problem.... This is linq to sql model: I set Entity namespace to be CMS.Model If I try to declare partial class Article in Portal.Models namespace: public partial class Article { .... } Then, after using Article article somewhere in code I get following error: 'Article' is an ambiguous reference between 'Portal.Models.Article' and 'CMS.Model.Article' Portal is project name and CMS is area.... I followed these instructions I aslo created NerdDinner from scratch and in that example validation works. I can't figure out what am I doing wrong... someone noticed my mistake? Is it related with giving name to Entity namespace (in tutorial they used default one) Thanks in advance! PS I'd like to note that I'm c# newbie so I'm not really familiar with these partial classes

  • [Java] Form data transition into entity beans to persist them by the server side ORM

    - by cscsaba242
    Hello guys, Is there any good explanation or tutorial which describes the common way how can we create entity beans from the received data of the form ? The main reason of my question the treating the received ids (e.g id of country,city and so forth) which is the way from the id to entity ? Example: ................Client side form username:String countryid:Integer (could be a drop down) ................Server side entities public class UserBean { String username; CountryBean Country; } public class CountryBean { String cityname; Integer id; } ............................................ Maybe the question is dependent of the used technology, but I guess there is a very common way. I would like to comprehend the conventional approach of this problem. (For the sake of the completeness I would like to save the form data (received by Stripes) by JPA) Thanks advance. cscsaba242

  • How to create a custom ADO Multi Dimensional Catalog with no database

    - by Alan Clark
    Does anyone know of an example of how to dynamically define and build ADO MD (ActiveX Data Objects Multidimensional) catalogs and cube definitions with a set of data other than a database? Background: we have a huge amount of data in our application that we export to a database and then query using the usual SQL joins, groups, sums etc to produce reports. The data in the application is originally in objects and arrays. The problem is the amount of data is so large the export can take 2 hours. So I am trying to figure out a good way of querying the objects in memory, either by a custom OLAP algorithm or library, or ADO MD. But I haven't been able to find an example of using ADO MD without a database behind it. We are using Delphi 2010 so would use ADO ActiveX but I imagine the ADO.NET MD is similar. I realize that if the application data was already stored in a database the problem would solve itself. Also if Delphi had LINQ capability I could query the objects and arrays that way.

  • Scala Programming for Android

    - by Lemmy
    I have followed the tutorial at Scala and Android with Scala 2.7.3 final. The resulting Android App works but even the most basic application takes several minutes (!) to compile and needs 900 kb compressed, which is a show stopper for mobile applications. Additionally, the IDE runs out of memory every now and then. I assume dex is not made for big libraries like the scala-library. So my question is: Has anyone actually done this and is there any cure for this?
