  • Oracle SELECT TOP 10 records

    - by ArneRie
    Hi, i have an big problem with an SQL Statement in Oracle. I want to select The TOP 10 Records ordered by STORAGE_DB wich arent in a list from an other select statement. This one works fine for all records: SELECT DISTINCT APP_ID, NAME, STORAGE_GB, HISTORY_CREATED, TO_CHAR(HISTORY_DATE, 'DD.MM.YYYY') AS HISTORY_DATE FROM HISTORY WHERE STORAGE_GB IS NOT NULL AND APP_ID NOT IN (SELECT APP_ID FROM HISTORY WHERE TO_CHAR(HISTORY_DATE, 'DD.MM.YYYY') = '06.02.2009') But when i am adding AND ROWNUM <= 10 ORDER BY STORAGE_GB DESC im getting some kind of "random" Records. I think because the limit takes in place before the order. Does someone has an good solution? The other problem: This query is realy slow (10k+ records)

  • Eclipse keyboard shortcuts: "alt+shift+" vs. "shift+" vs. "ctrl+alt+" etc. -- Is there an underlying

    - by MatrixFrog
    There are a zillion questions on SO about keyboard shortcuts in Eclipse, but there's I've always wondered if there is an underlying logic to the decisions of which shortcuts would be ctrl+alt+[some letter], and which would be just ctrl+[some letter] etc. Obviously there is a need to use a variety of combinations because there are only so many keys on the keyboard, but why, for example, is "add import" ctrl+shift+m, while "extract method" is alt+shift+m, instead of the other way around? I think if there is some underlying logic to these decisions, it will make it easier to remember more shortcuts without having to scan through the huge right-click menus to find them, and I won't accidentally use the wrong one as often.

  • XStream <-> Alternative binary formats (e.g. protocol buffers)

    - by sehugg
    We currently use XStream for encoding our web service inputs/outputs in XML. However we are considering switching to a binary format with code generator for multiple languages (protobuf, Thrift, Hessian, etc) to make supporting new clients easier and less reliant on hand-coding (also to better support our message formats which include binary data). However most of our objects on the server are POJOs with XStream handling the serialization via reflection and annotations, and most of these libraries assume they will be generating the POJOs themselves. I can think of a few ways to interface an alternative library: Write an XStream marshaler for the target format. Write custom code to marshal the POJOs to/from the classes generated by the alternative library. Subclass the generated classes to implement the POJO logic. May require some rewriting. (Also did I mention we want to use Terracotta?) Use another library that supports both reflection (like XStream) and code generation. However I'm not sure which serialization library would be best suited to the above techniques.

  • Index was outside the bounds of the array. IndexOutOfRangeException in LINQ to SQL

    - by gtas
    Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

  • Recognizing when to use the mod operator

    - by Will
    I have a quick question about the mod operator. I know what it does; it calculates the remainder of a division. My question is, how can I identify a situation where I would need to use the mod operator? I know I can use the mod operator to see whether a number is even or odd and prime or composite, but that's about it. I don't often think in terms of remainders. I'm sure the mod operator is useful and I would like to learn to take advantage of it. I just have problems identifying where the mod operator is applicable. In various programming situations, it is difficult for me to see a problem and realize "hey! the remainder of division would work here!" Any tips or strategies? Thanks

  • Does JSONP scale? How many JSONP requests can I send?

    - by Cheeso
    Based on Please explain JSONP, I understand that JSONP can be used to get around the same-origin policy. But in order to do that, the page must use a <script> tag. I know that pages can dynamically emit new script tags, such as with: <script type="text/javascript" language='javascript'> document.write('<script type="text/javascript" ' + 'id="contentloadtag" defer="defer" ' + 'src="javascript:void(0)"><\/script>'); var contentloadtag=document.getElementById("contentloadtag"); contentloadtag.onreadystatechange=function(){ if (this.readyState=="complete") { init(); } } </script> (the above works in IE, don't think it works in FF). ... but does this mean, effectively, that every JSONP call requires me to emit another <script> tag into the document? Can I remove the <script> tags that are done?

  • Best way to find updates in xml feed

    - by misterjinx
    Hello all, I have an xml feed that I have to check periodically for updates. The xml consists of many elements and I'm looking to figure it out which is the best (and probably faster) way to find out which elements suffered updates from last time I've checked. What I think of is to check first the lastBuildDate for modifications and if it differs from the previous one to start parse the xml again. This would involve keeping each element with all of its attributes in my database. But each element can have different number of attributes as well as other nested elements. So if it would be to store each element in my database what would be the best way to keep them ? That's why I'm asking for your help :) Thank you.

  • Using recursion to find paths in a 2D array

    - by rikkit
    Hi, I'm working on a project for my A level. It involves finding the maximum flow of a network, and I'm using javascript. I have a 2D array, with values in the array representing a distance between the two points. An example of the array: 0 2 2 0 0 0 1 2 0 0 0 2 0 0 0 0 I think I need to use a recursive technique to find a path; below is some pseudocode, assuming that the array is 4x4. a is (0,0), b is (3,3). function search(a,b) from a to b if element(i,j) != 0 then store value of element search(j,3) I was wondering if that was the right construction for a depth first search. Thanks for any help.

  • downgrade mapserver

    - by ricardo
    hello all, a question, as I can uninstall and install mapserver an older version, since I is causing roughly following error and I think is the version of the same Warning: [MapServer Error]: msLoadSymbolSet(): First token must be SYMBOLSET, this doesn't look like a symbol file. in /var/www/obtra/vcauca.php on line 25 Warning: Failed to open map file obtra_1.map in /var/www/obtra/vcauca.php on line 25 Fatal error: Call to a member function getLayerByName() on a non-object in /var/www/obtra/vcauca.php on line 33 this in ubuntu 8.04 if it is not possible please where I can get an older version that I recommended to avoid mistakes and to update the system. thanks for your suggestions and answers

  • How to get MAX value of a version-number (varchar) column in T-SQL

    - by Ogre Psalm33
    I have a table defined like this: Column: Version Message Type: varchar(20) varchar(100) ---------------------------------- Row 1: 2.2.6 Message 1 Row 2: 2.2.7 Message 2 Row 3: 2.2.12 Message 3 Row 4: 2.3.9 Message 4 Row 5: 2.3.15 Message 5 I want to write a T-Sql query that will get message for the MAX version number, where the "Version" column represents a software version number. I.e., 2.2.12 is greater than 2.2.7, and 2.3.15 is greater than 2.3.9, etc. Unfortunately, I can't think of an easy way to do that without using CHARINDEX or some complicated other split-like logic. Running this query: SELECT MAX(Version) FROM my_table will yield the erroneous result: 2.3.9 When it should really be 2.3.15. Any bright ideas that don't get too complex?

  • What are the best programming and development related Blogs?

    - by Christopher Cashell
    There are lots of great resources available on the Internet for learning more about programming and improving your skills. Blogs are one of the best, IMO. There's a wealth of knowledge and experience, much of it covering topics not often found in traditional books, and the increased community aspect helps to bring in multiple viewpoints and ideas. We're probably all familiar with Coding Horror and Joel on Software (so no need to mention them), but what are the other great ones out there? What are the Blogs that you find yourself following most closely? Where you see the best new ideas, the most interesting or informative ideas, or just the posts that make you sit back and think? One Blog per answer, and then we'll vote up the best so we can all learn from them.

  • JPA 2.0 Implementations comparison : Hibernate 3.5 vs EclipseLink 2 vs OpenJPA 2

    - by peperg
    What's your choice? Do You have any suggestions and experience? I'm developing an application with Hibernate 3.5 and Spring 3.0 Pros: Good documentation Easy configuration and helpful logs Popularity - wide community Some extensions to JPA Some additional Tools - JBoss Tools for Eclipse, hbm2ddl, generating static metamodel etc... Cons: Bugs! (Sequences, collections etc...) Lots of reatures are doubled with "pure" Hibernate. There's a mess in legacy Hibernate and JPA annotations. I'm considering to switch to EclipseLink. What do You think ? Edit: I've tried EclipseLink and have very bad experiences. It seems like EclipseLink needs LoadTimeWeaver and likes to run on OSGi platform rather than simple Jetty or Tomcat environment. I just don't have time for all this configuration stuff.

  • where to get free 1440 cron jobs a day??

    - by Nok Imchen
    Well, I'm making a program for my own use. In this program, i need to set up cron job. The cron job should run every minute (24 hr * 60 mins = 1440 times). Thus, I'll need to set up a cron job with a frequency of 1 minute. I think Google app engine gives free cron job. But i'm very new to it. I downloaded the java SDK and read the document but understood nothing :( So, i cant use Google app engine. Is here any other free service like Google app engine which but with easier inferface??? all i want is a cron job with 1 minute frequency please help/suggest me.... thank you

  • Building webparts with Visual Studio 2010 Express

    - by MalphasWats
    Hi, I'm trying to get started with building my own webparts, planning to follow this MSDN article. I've downloaded Visual C# 2010 Express - I'm not quite at the point where I feel comfortable dropping 1000 big ones yet, and I installed Visual Web Developer 2010 Express via the WPInstaller. Following through the tutorial, aside from the fact that I don't get the option to create a "Web Control Library", a gap I filled with this article, I can't seem to find the sn.exe tool (or the "Visual Studio 2005 Command Prompt"!). I know it's not quite a direct programming related question, but I can't even get the thing going yet! Any help is appreciated. Thanks EDIT:- I think I may be jumping the gun quite considerably, I wrote a simple hello world example and tried to build it but it doesn't have any references to the Microsoft.SharePoint packages and they don't appear in my lists. Am I understanding some more research I've done (namely this) correctly, in that I have to actually have a full installation of actual SharePoint on the machine I'm developing on?

  • Storing hierarchical (parent/child) data in Python/Django: MPTT alternative?

    - by Parand
    I'm looking for a good way to store and use hierarchical (parent/child) data in Django. I've been using django-mptt, but it seems entirely incompatible with my brain - I end up with non-obvious bugs in non-obvious places, mostly when moving things around in the tree: I end up with inconsistent state, where a node and its parent will disagree on their relationship. My needs are simple: Given a node: find its root find its ancestors find its descendants With a tree: easily move nodes (ie. change parent) My trees will be smallish (at most 10k nodes over 20 levels, generally much much smaller, say 10 nodes with 1 or 2 levels). I have to think there has to be an easier way to do trees in python/django. Are there other approaches that do a better job of maintaining consistency?

  • VS2008 Setup Project for C# Project

    - by xopht
    I've built app using wmp.dll which is Windows System File in my XP machine. If I tried add outputs of above project to my Setup Project, VS warned that ''wmp.dll' should be excluded because its source file 'C:\WINDOWS\system32\wmp.dll' is under Windows System File Protection'. There're three things under 'Detected Dependencies' folder. Microsoft .NET Framework, Interop.WMPLib.dll and wmp.dll. The app works okay in my machine, of course. But if I install this into Windows Server 2003 machine, the app does not be launched. I think this is because different version of OS use different version of wmp.dll. Anyway, how can I fix this? ps. I've even excluded wmp.dll from the Setup Project.

  • springTestContextBeforeTestMethod failed in Maven spring-test

    - by joejax
    I try to setup a project with spring-test using TestNg in Maven. The code is like: @ContextConfiguration(locations={"test-context.xml"}) public class AppTest extends AbstractTestNGSpringContextTests { @Test public void testApp() { assert true; } } A test-context.xml simply defined a bean: <bean id="app" class="org.sonatype.mavenbook.simple.App"/> I got error for Failed to load ApplicationContext when running mvn test from command line, seems it cannot find the test-context.xml file; however, I can get it run correctly inside Eclipse (with TestNg plugin). So, test-context.xml is under src/test/resources/, how do I indicate this in the pom.xml so that 'mvn test' command will work? Thanks, UPDATE: Thanks for the reply. Cannot load context file error was caused by I moved the file arround in different location since I though the classpath was the problem. Now I found the context file seems loaded from the Maven output, but the test is failed: Running TestSuite May 25, 2010 9:55:13 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from class path resource [test-context.xml] May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.GenericApplicationContext@171bbc9: display name [org.springframework.context.support.GenericApplicationContext@171bbc9]; startup date [Tue May 25 09:55:13 PDT 2010]; root of context hierarchy May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.context.support.GenericApplicationContext@171bbc9]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99 May 25, 2010 9:55:13 AM org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99: defining beans [app,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor]; root of factory hierarchy Tests run: 3, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 0.63 sec <<< FAILURE!

I don't think this is the right way, didn't find much info from spring-test doc. If you know spring test framework, please shred some light on this.

  • I've Heard Global Variables Are Bad, What Alternative Solution Should I Use?

    - by Jay
    I've read all over the place that global variables are bad and alternatives should be used. In Javascript specifically, what solution should I choose. I'm thinking of a function, that when fed two arguments (function globalVariables(Variable,Value)) looks if Variable exists in a local array and if it does set it's value to Value, else, Variable and Value are appended. If the function is called without arguments (function globalVariables()) it returns the array. Perhaps if the function is fired with just one argument (function globalVariables(Variable)) it returns the value of Variable in the array. What do you think? I'd like to hear your alternative solutions and arguments for using global variables.

  • Using LINQ Group By to return new XElements

    - by Jon
    I have the following code and got myself confused: I have a query that returns a set of records that have been identified as duplicates and I then want to create a XElement for each one. This should be done in one query I think but I'm now lost. var f = (from x in MyDocument.Descendants("RECORD") where itemsThatWasDuplicated.Contains((int)x.Element("DOCUMENTID")) group x by x.Element("DOCUMENTID").Value into g let item = g.Skip(1) //Ignore first as that is the valid one select item ); var errorQuery = (from x in f let sequenceNumber = x.Element("DOCUMENTID").Value let detail = "Sequence number " + sequenceNumber + " was read more than once" select new XElement("ERROR", new XElement("DATETIME", time), new XElement("DETAIL", detail), new XAttribute("TYPE", "DUP"), new XElement("ID", x.Element("ID").Value) ) );

  • What is the right way to initialize a constant in Ruby?

    - by zbrimhall
    I have a simple class that defines some constants, e.g.: module Foo class Bar BAZ = "bof" ... Everything is puppies and rainbows until I tell Rake to run all my Test::Unit tests. When it does, I get warnings: bar.rb:3: warning: already initialized constant BAZ My habit has been to avoid these warnings by making the constant initialization conditional, e.g.: ... BAZ = "bof" unless const_defined? :BAZ ... This seems to solve the problem, but it is a little tedious, and I don't ever see anyone else initializing constants this way. This makes me think I might be Doing It Wrong. Is there a better way to initialize constants that won't generate warnings?

  • How to add lowercase field to NSURLRequest header field?

    I'm getting pretty frustrated figuring out how to add a lowercase header field to an NSMutableURLRequest. NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:MyURLString]]; [urlRequest setValue:@"aValue" forHTTPHeaderField:@"field"]; In the example above, "field" get's switched to "Field," since the header field names are case insensitive. I wouldn't think this should happen, but it does. The API I am working with is case sensitive, so my GET request is ignored. Is there any way to override the case switch? Thanks

  • What's the best JSF implementation?

    - by Jeff
    Hey everyone, I currently have a medium size Java web application sitting on top of Spring MVC. As much as I like (no sarcasm) coding straight HTML, CSS and JS, it's not possible for me to develop as fast as I'd like. I'm looking at different RAD frameworks to speed up my development. I'm looking at JSF implementations and component libraries, Flex, GWT and a few others. As of now, Apache MyFaces (with ICEFaces) seems to be the front runner in my mind, but I'm curious to find out what you all think of that specific implementation and if the Sun implementation is any better? What's important to me is something that is stable, has an active community and that it doesn't look like there is another technology in the near future that is going to eclipse JSF (which would drive me to use a different RAD framework). Thanks in advance for the responses.

  • Problem with Gallio and TeamCity and the new Visual Studio 2010 release

    - by Bernard Larouche
    I am running TeamCity on a virtual machine. I have installed the new Visual Studio 2010 release yesterday and converted my VS 2008 projects. I also have installed .NET Framework 4 on my virtual machine. Before yesterday all my projects were building succesfully on the CI server but since I installed VS 2010 I get the following error message : error MSB5014: File format version is not recognized. MSBuild can only read solution files between versions 7.0 and 9.0, inclusive. I did change my config on Team City to take into account the new .NET 4 framework : Build Runner : MSBuild Build File Path : CFT.msbuild MSBuild version : Microsoft.NET Framework 4.0 MSBuild ToolsVersion : 4.0 Run Platform : x86 I think it has something to do with the fact that now MSBuild must refer to .NET 4 framwork but it seems that it keeps refering to 2.0.
