• MySQL query returns different set of results on two identical databases

  - by 1nsane

  I exported a live MySQL database (running mysql 5.0.45) to a local copy (running mysql 5.1.33) with no errors upon import. There is a view in the database, that when executed locally, returns a different set of data than when executed remotely. It's returning 32 results instead of 63. When I execute the raw sql, the same problem occurs. I've inspected the data in all tables being joined, and the counts are the same. The query is simple and has no where conditions - but about 10 joins. Aside from the differences in mysql versions... I can't find any reason that this query would return different results between databases... since they are effectively exact copies. Has anyone experienced a problem like this before?

• nsthread in iphone xcode

  - by BibiBuBu

  Good Day! i want to use nsthreads in a project of xcode that will call a function which is for the network access and will check that if the network is there or not, so i need to have a thread which will execute after lets say 1 minutes to check the connectivity. and will continue run unless the app is closed. [NSThread detachNewThreadSelector:@selector(startTheBackgroundJob) toTarget:self withObject:nil]; startTheBackgroundJob NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // wait for 3 seconds before starting the thread, you don't have to do that. This is just an example how to stop the NSThread for some time [NSThread sleepForTimeInterval:5]; //[self performSelectorInBackground:@selector(checkNet) withObject:nil]; [self performSelectorOnMainThread:@selector(checkNet) withObject:nil waitUntilDone:YES]; [pool release]; it works only for the first time but not any other, i mean only 1 loop it makes can somebody help me in this regard. Thanks

• How can I implement an abstract singleton class in Java?

  - by Simon

  Here is my sample abstract singleton class: public abstract class A { protected static A instance; public static A getInstance() { return instance; } //...rest of my abstract methods... } And here is the concrete implementation: public class B extends A { private B() { } static { instance = new B(); } //...implementations of my abstract methods... } Unfortunately I can't get the static code in class B to execute, so the instance variable never gets set. I have tried this: Class c = B.class; A.getInstance() - returns null; and this ClassLoader.getSystemClassLoader().loadClass("B"); A.getInstance() - return null; Running both these in the eclipse debugger the static code never gets executed. The only way I could find to get the static code executed is to change the accessibility on B's constructor to public, and to call it. I'm using sun-java6-jre on Ubuntu 32bit to run these tests.

• Calling oracle stored procedure from Excel - VBA

  - by Ram

  I have to execute an Oracle stored procedure from vba (Excel) with around 38 input parameters. The stored procedure will insert some values in the destination table once that is executed. When it is executed through VBA the number of fields which is inserted is less than when it is executed directly from the backend (oracle). For example it is creating around 17 fields of records while executing directly from the back end. (I have created a wrapper class in the back-end and passing the same parameter values in the back-end.). It is creating around 15 fields of records while executing from the excel VBA in the destination table. Kindly let me know what could be the possible reasons for this.

• Symfony2 trans_default_domain is not working

  - by user1069843

  At the end of http://symfony.com/doc/current/book/translation.html#twig-templates I read about {% trans_default_domain "app" %} to set a translation domain for a whole template. But for me it does not work. Calling app/console translation:extract de --dir=src/ --output-dir=app/Resources/translations --output-format=xliff --keep Just puts all messages in the messages.de.xliff file. But if I set the domain manually for a given label like {{ label.name|trans({}, 'app') }} And execute the same extract command as above, then I get a new file app.de.xliff Is there anything more to do when using trans_default_domain?

• In NHibernate, how do I combine two DetachedCriteria instances

  - by Trevor

  My scenario is this: I have a base NHibernate query to run of the form (I've coded it using DetachedCriteria , but describe it here using SQL syntax): SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key The user interface to show the results of this join allows the user to specify additional criteria: Say: I.SomeField = 'UserValue'. Now, I need the final load command to be: SELECT * FROM Items I INNER JOIN SubItems S on S.FK = I.Key WHERE I.SomeField = 'UserValue' My problem is: I've created a DetachedCriteria with the 'static' aspect of the query (the top join) and the UI creates a DetachedCriteria with the 'dynamic' component of the query. I need to combine the two into a final query that I can execute on the NHibernate session. DefaultCriteria.Add() takes an ICriterion (which are created using the Expression class, and maybe other classes I don't know of which could be the solution to my problem). Does anyone know how I might do what I want?

• Pre-built UI components for displaying SSRS Local Mode Parameters

  - by namenlos

  BACKGROUND Am writing a WinForm app that uses the SSRS Report Viewer control to render reports in local mode - there is no SSRS server involved at all I can successully create and execute reports in local mode What I want to do is add Parameters to the report THE PROBLEM When the Report Viewer control executes a report in local mode it does not provide any UI that allows the user to enter values for parameters defined in the report This is in contrast to to when the Report Viewer control is running a server report - parameters are shown. MY QUESTION Are there pre-built components or even sample code I can use that would provide a reasonble parameter user experience for this scenario (scenario = SSRS + Report Viewer Control + Local Mode)? Yes, I could write this UI code myself - what I am looking for is existing code to avoid having to implement this UI because I'd rather spend my time making the content of the report work well NOTES Switching to another reporting engine besides SSRS is not an option. Switching to server side reports is not an option.

• NoSuchMethodError with Spring MutableValues

  - by jakob

  Hello experts! I have written a test where i specify my application context location with annotations. I then autowire my dao into the test. @ContextConfiguration(locations = {"file:service/src/main/webapp/WEB-INF/applicationContext.xml"}) public class MyTest extends AbstractTestNGSpringContextTests { @Autowired protected MyDao myDao; private PlatformTransactionManager transactionManager; private TransactionTemplate transactionTemplate; @Test public void shouldSaveEntityToDb() { transactionTemplate.execute(new TransactionCallbackWithoutResult() { protected void doInTransactionWithoutResult(TransactionStatus status) { Entity entity = new Entity(); //test myDao.save(entity) //assert assertNotNull(entity.getId()); } }); } When i run the test i get an exception which states that the application context could not be loaded and it boils down to: Caused by: java.lang.NoSuchMethodError: org.springframework.beans.MutablePropertyValues.add(Ljava/lang/String;Ljava/lang/Object;)Lorg/springframework/beans/MutablePropertyValues; I have no idea where to start looking, why do i get this error and how can i resolve it?

• How to compress CSS/JS in VS2010 Web Deployment Build Template?

  - by RPM1984

  Hi all, We've recently upgraded from VS2008 - VS2010 (and hence upgrading from Web Deployment Project to proper deployment project). Obviously what's new in VS2010 web deployments is the introduction of Workflow as the build process template. Previously, we used a MSBuild task in the WDP to execute the Yahoo YUI Javascript/CSS compression module to minify/compress javascript and css files. Has anyone managed to accomplish this task with Visual Studio 2010? I have seen the new "SquishIt" compressor created by Justin Etheridge, but its not ideal as it "squishes" on the fly (e.g on Application_Start - Global.ascx) - which means you still have to push out all the uncompressed files to your web server before squishing. In the Workflow designer - i can see a toolbox item called "MSBuild" - just dont know how to use it to accomplish what i want. Been searching high and wide, no-one seems to know how. Surely someone out there has done this.

• How to do this GQL query in JDO

  - by TheDon

  I have about 50k entities stored in appengine. I am able to look up an individual record via the GQL admin interface with a query like: SELECT * FROM Pet where __key__ = KEY( 'Pet','Fido') But I'm having trouble figuring out how to do a batch version of this via JDO. Right now I have this: PersistenceManager pm = ...; for(Pet pet : pets) { for(String k : getAllAliases(pet)) { keys.add(KeyFactory.createKeyString(Pet.class.getSimpleName(), k)); } } Query q = pm.newQuery("select from " + Pet.class.getName() + " where id == :keys"); List<Pet> petlist = (List<Pet>) q.execute(keys); But though 'Fido' works in the GQL case, it returns nothing when I use that Java + JDO code. What am I doing wrong?

• Firebird .NET: Database backup not working (small file)

  - by Norbert

  Hi, I am trying to backup my Firebird 2.5 database file by code: FbBackup backupSvc = new FbBackup(); backupSvc.ConnectionString = MyConnectionManager.buildConnectionString(); backupSvc.BackupFiles.Add(new FbBackupFile(backupPathFilenameAndExtension, 2048)); backupSvc.Verbose = true; backupSvc.Options = FbBackupFlags.IgnoreLimbo; backupSvc.Execute(); The database gets saved to the specified directory. However, the file saved file is only 168kB large. The original database is nearly 7MB in size. What goes wrong? Thanks, Norbert

• How can I convert .eps files to .jpg in ASP.NET?

  - by Mike C

  I am trying to convert uploaded .eps files to .jpg in my ASP.net application and I am having a hard time finding a .net library that will let me do this. I have tried using the ImageMagick libraries, but I don't have root access to the server in order to install the standard binaries, or run the command line executables. I have also tried the slightly modified project from CodeProject, but it was designed in VS2005 and I have VS2008 and 2010 and I think I run into some compatibility issues while trying to compile and execute the project. Is there a simpler solution available that just works natively in .NET? Thanks, Mike

• SignalR cross domain does not work after updating to 0.5.1

  - by jlp

  My site uses SignalR to communicate cross-domain. It worked great but I updated SignalR from 0.5.0 to 0.5.1 and my site broke. Here's my script: function start() { $.connection.hub.url = "http://otherdomain.com/signalr"; $.connection.hub.start().done(function () { $.connection.myHub.join(); }); } When script calls join - I see in Firebug that it is a POST (I believe it shoold be GET (jsonp) since it is cross domain) with no response. EDIT: I tried $.connection.hub.start({jsonp: true}). Now I have can call server from client but calls from server don't execute on client. I noticed that there are following calls: negotiate and send whereas locally (the same domain) there are: negotiate, connect, send.

• Transpose a file in bash

  - by Thrawn

  Hi all, I have a huge tab-separated file formatted like this X column1 column2 column3 row1 0 1 2 row2 3 4 5 row3 6 7 8 row4 9 10 11 I would like to transpose it in an efficient way using only using commands (I could write a ten or so lines Perl script to do that, but it should be slower to execute than the native bash functions). So the output should look like X row1 row2 row3 row4 column1 0 3 6 9 column2 1 4 7 10 column3 2 5 8 11 I thought of a solution like this cols=`head -n 1 input | wc -w` for (( i=1; i <= $cols; i++)) do cut -f $i input | tr $'\n' $'\t' | sed -e "s/\t$/\n/g" >> output done But it's slow and doesn't seem the most efficient solution. I've seen a solution for vi in this post, but it's still over-slow. Any thoughts/suggestions/brilliant ideas? :-)

• Can't get SubSonic insert to work

  - by Darkwater23

  I'm trying to insert a record into a table without using the SubSonic object in a VB.Net Windows app. (It will take too long to explain why.) Dim q As New SubSonic.Query("tablename") q.QueryType = SubSonic.QueryType.Insert q.AddUpdateSetting("Description", txtDescription.Text) q.Execute() This just updates all the rows in the table. I read in one post that instead of AddUpdateSetting, I should use AddWhere, but that didn't make any sense to me. I don't need a where clause at all. Searching for all:QueryType.Insert at subsonicproject.com didn't return anything (which I thought was weird). Can anyone tell me how to fix this query? Thanks!

• PDO::fetchAll vs. PDO::fetch in a loop

  - by Byron

  Just a quick question. Is there any performance difference between using PDO::fetchAll() and PDO::fetch() in a loop (for large result sets)? I'm fetching into objects of a user-defined class, if that makes any difference. My initial uneducated assumption was that fetchAll might be faster because PDO can perform multiple operations in one statement while mysql_query can only execute one. However I have little knowledge of PDO's inner workings and the documentation doesn't say anything about this, and whether or not fetchAll() is simply a PHP-side loop dumped into an array. Any help?

• Warning: array_multisort() [function.array-multisort]: Argument #1 is expected to be an array or a

  - by johnny

  Hi, the following code produces the error in the title. I've tried to google it, but all I got were pages who got the same error (and not an explanation thereof). This isn't really a problem since it's actually working and cancelling the error out with the @ works out just fine. Though I'm still wondering why I haven't been able to execute array_multisort just once without getting this error. public function getMostRelevant(){ list($occurrences, $keywords) = $this->occurr_keyw_array; array_multisort($occurrences, SORT_DESC, SORT_NUMERIC, $keywords); $return_array = array( array($occurrences[0], $keywords[0]), array($occurrences[1], $keywords[1]), array($occurrences[2], $keywords[2]) ); return $return_array; }

This is what I have so far: public static IEnumerable<arma_ocorrencium> ListArmasOcorrencia() { if (logger.IsInfoEnabled) { logger.Info("ListarArmasOcorrencia: start"); } var db = new BdvdDB(); var select = from p in db.arma_ocorrencia select p; var results = select.ToList<arma_ocorrencium>(); //Execute the query here if (logger.IsInfoEnabled) { // log sql here } if (logger.IsInfoEnabled) { logger.Info("ListarArmasOcorrencia: end"); } return results; }

• How to find the filename of a script being run when it is executed from a symlink on linux

  - by Phil Boltt

  Hi, If I have a python script that is executed via a symlink, is there a way that I can find the path to the script rather than the symlink? I've tried using the methods suggested in this question, but they always return the path to the symlink, not the script. For example, when this is saved as my "/usr/home/philboltt/scripts/test.py" : #!/usr/bin/python import sys print sys.argv[0] print __file__ and I then create this symlink ln -s /usr/home/philboltt/scripts/test.py /usr/home/philboltt/test and execute the script using /usr/home/philboltt/test I get the following output: /usr/home/philboltt/test /usr/home/philboltt/test Thanks!

• Subsonic 3 fails to identify Stored Procedure Output Parameter

  - by CmdrTallen

  Hi using Subsonic 3.0.0.3 it appears there is some issue with Subsonic identifying Stored Procedure paramters as output parameters. In the StoredProcedures.cs class I find my stored procedure definition but the last parameter is defined incorrectly as a 'AddParameter'. sp.Command.AddParameter("HasPermission",HasPermission,DbType.Boolean); When I sp.Execute() and attempt to read the value of the sp.Command.OutputValues[0] the value is null. If the definition is edited to be like this; sp.Command.AddOutputParameter("HasPermission", DbType.Boolean); Then the value is returned and is correct value type I am not sure how I 'fix' this - as everytime I regen the SP class via the 'Run Custom Tool' the parameter definitions require editing. Should I edit a T4 template somehow? Please advise. EDIT: I forgot to mention I am using MS SQL 2008 (10.0.2531)
