  • Why is using OPENQUERY on a local server bad?

    - by Ziplin
    I'm writing a script that is supposed to run around a bunch of servers and select a bunch of data out of them, including the local server. The SQL needed to SELECT the data I need is pretty complicated, so I'm writing sort of an ad-hoc view, and using an OPENQUERY statement to get the data, so ultimately I end up looping over a statement like this: exec('INSERT INTO tabl SELECT * FROM OPENQUERY(@Server, @AdHocView)') However, I've heard that using OPENQUERY on the local server is frowned upon. Could someone elaborate as to why?

  • Maven webapp with maven-eclipse-plugin doesn't generates <dependent-module>

    - by chrsk
    I use the eclipse:eclipse goal to generate an Eclipse Project environment. The deployment works fine. The goal creates the var classpath entries for all needed dependencies. With m2eclipse there was the Maven Container which defines an export folder which was WEB-INF/lib for me. But i don't want to rely on m2eclipse so i don't use it anymore. the class path entries which are generated by eclipse:eclipse goal don't have such a export folder. While booting the servlet container with WTP it publishes all resources and classes except the libraries to the context. Whats missing to publish the needed libs, or isn't that possible without m2eclipse integration? Enviroment Eclipse 3.5 JEE Galileo Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200) Java version: 1.6.0_14 m2eclipse The maven-eclipse-plugin configuration <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.8</version> <configuration> <projectNameTemplate>someproject-[artifactId]</projectNameTemplate> <useProjectReferences>false</useProjectReferences> <downloadSources>false</downloadSources> <downloadJavadocs>false</downloadJavadocs> <wtpmanifest>true</wtpmanifest> <wtpversion>2.0</wtpversion> <wtpapplicationxml>true</wtpapplicationxml> <wtpContextName>someproject-[artifactId]</wtpContextName> <additionalProjectFacets> <jst.web>2.3</jst.web> </additionalProjectFacets> </configuration> </plugin> The generated files After executing the eclipse:eclipse goal, the dependent-module is not listed in my generated .settings/org.eclipse.wst.common.component, so on server booting i miss the depdencies. This is what i get: <?xml version="1.0" encoding="UTF-8"?> <project-modules id="moduleCoreId" project-version="1.5.0"> <wb-module deploy-name="someproject-core"> <wb-resource deploy-path="/" source-path="src/main/java"/> <wb-resource deploy-path="/" source-path="src/main/webapp"/> <wb-resource deploy-path="/" source-path="src/main/resources"/> </wb-module> </project-modules>

  • Boost Jam vs Jam

    - by User1
    I recently built the Boost libraries in Linux and noticed the package needed an executable called bjam in order to do the build. Is bjam related to jam? If it is related to jam, did they somehow extend (or even dumb-down) bjam? Is it used only for building Boost libraries or is it a general build tool for anything?

  • eclipse serveral ant build file

    - by Alex
    Hi, currently I'm developing in eclipse 3.5 in different project web applications for tomcat 6.0.24. For each of this project I have written a ant build file to generate the war file to deploy the project to the tomcat container. So I have to run for each project the ant build file (a lot of clicks, and a waste of time). Question: Is there a possibility to run all needed ant build files with a single click, from a single project or whatever? Best regards, Alex

  • Cocoa - Timer object that can be started, suspended, resumed?

    - by psychotik
    I'm looking for a repeating timer object that allows me to create it once and then suspend and resume it as needed for the lifetime of my application. I've seen documentation for NSTimer and although I think I can make it do what I want by building an abstraction on top of it that creates/invalidates timer objects multiple times, I was curios if there is a better way using some other system timer implementation. I'm not too familiar with Mac development and couldn't find any other leads besides NSTimer.

  • How to implement continuations?

    - by Kyle Cronin
    I'm working on a Scheme interpreter written in C. Currently it uses the C runtime stack as its own stack, which is presenting a minor problem with implementing continuations. My current solution is manual copying of the C stack to the heap then copying it back when needed. Aside from not being standard C, this solution is hardly ideal. What is the simplest way to implement continuations for Scheme in C?

  • SecurityFlushSessionListener in jboss

    - by techzen
    In jboss-web.deployer/conf/web.xml there is a listener defined called SecurityFlustSessionListener. This listener searches for the component java:comp/env/security/securityMgr and if not found prints that info in the debug log. It is understood that if this security feature is not needed then, one can simply remove this listener. How have you used this listener for configuring security at the time of session destroying? As in, can you highlight the use cases of this listener and the scenarios where it was found useful?

  • Again, user config files C#

    - by George
    Hey guys. I have a large config file (user) that i needed to go to the right location and have some default values. Since i have a installer class, i added some parameter setting to the config file in it, but created the config files in the installers folder. What is the best way to ensure these default parameters will be written only once, and in the right location?

  • finding shortest valid path in a colored-edge graphs

    - by user1067083
    Given a directed graph G, with edges colored either green or purple, and a vertex S in G, I must find an algorithm that finds the shortest path from s to each vertex in G so the path includes at most two purple edges (and green as much as needed). I thought of BFS on G after removing all the purple edges, and for every vertex that the shortest path is still infinity, do something to try to find it, but I'm kinda stuck, and it takes alot of the running time as well... Any other suggestions? Thanks in advance

  • UML Diagrams. When are they used?

    - by user69514
    So ok I understand that UML diagrams help for the construction of a program, but when are they used? Are they needed before you start coding? do you need them so you know what you have to code? Or do you use them after you have coded the program?

  • Making Latex typeset given text on two facing pages

    - by Charles Stewart
    How do I encourage/make Latex typeset some portion of text so that it will all appear on a consecutive even-page, odd-page pair of pages? With trial and error, \nopagebreak can be coaxed into doing this, but is there a strategy that Just Works? Something like a samepage environment would be ideal, but one that: Will force a pagebreak on odd pages if that is needed to get all the text on facing pages; Allows up to one page break anywhere in the environment body, and fails noisily if that can't be ensured.

  • linq2sql: singleton or using, best practices

    - by zerkms
    what is the preferred practice when linq2sql using (in asp.net mvc applications): to create "singleton" for DataContext like: partial class db { static db _db = new db(global::data.Properties.Settings.Default.nanocrmConnectionString, new AttributeMappingSource()); public static db GetInstance() { return _db; } } or to retrieve new instance when it needed within using: using (db _db = new db()) { ... } the usage of using brings some limitations on code. so I prefer to use singleton one. is it weird practice?
