  • Using subselect to accomplish LEFT JOIN

    - by Andre
    Is is possible to accomplish the equivalent of a LEFT JOIN with subselect where multiple columns are required. Here's what I mean. SELECT m.*, (SELECT * FROM model WHERE id = m.id LIMIT 1) AS models FROM make m As it stands now doing this gives me a 'Operand should contain 1 column(s)' error. Yes I know this is possible with LEFT JOIN, but I was told it was possible with subselect to I'm curious as to how it's done.

  • Entity Framework foreign relationship issue

    - by Doug Hope
    I've had an entity framework model working for some time. Yesterday, it suddenly started complaining about a foreign key relationship issue during an insert. I've checked the fields and can do a manual insert using the exact field values. But the EF continues to complain. Any ideas what could have happened?

  • Are there any modeling tools that can visually generate jpa or sql queries?

    - by Shervin
    Does anyone know of a tool like PowerArchitect or SquirrelSQL or maybe eclipse plugin that lets you also generate jpa/sql queries? Imagine you choosing your database, or your entity beans, and the modeling would reverse engineer your database/entity model, so that you could visually just choose the columns you wanted to select, and it would generate jpa or sql queries for you. For instance choosing A.b and X.y would generate something like this: select a.b, x.y from A a, X x join ......

  • Distribute terrabyte files to the public from web server

    - by MarkJ
    Hi We need to set up a website which makes two or three large files publicly available - the files will be 1 or 2 terrabytes each. Although they will be public, in practise I expect only a relatively small number of scientists will want to download them. What is the best way to allow this? I've had a quick talk to a web-hosting provider (rackspace) and they suggested a hybrid solution. An entry-level managed server (we predict fairly low traffic for the website, but we do need to install some custom CGI software). Some cloud storage which hooks into Limelight Networks. This would host the large files, for download by FTP. It sounded OK to me but I know relatively little about server administration. Does it make sense? Thanks in advance, Mark

Any ideas?

  • Mongrel not using latest deployed code, despite multiple restarts

    - by ming yeow
    What could be the potential reasons why mongrel does not use the latest code in the ~/current branch? The code changes are in the MODELs. The code changes in the CONTROLLERS TAKE EFFECT. I tried the following: god restart app deploying several times manually stopping mongrel cluster, deleting the pid files, and starting them again Anyone has similar experiences? Where could the server be potentially caching the model files?

  • WCF threading - non-responsive UI

    - by Sphynx
    Hi everyone. I'm trying to configure some WCF stuff. Currently, I have a server which allows remote users to download files, and client. In the server, I use a ServiceHost class. I assume it should be running on a separate thread, however, the server UI (WinForms) becomes locked when someone downloads a file. Is there a way to manage the WCF threading model? Thank you!

  • C# Select clause returns system exception instead of relevant object

    - by Kashif
    I am trying to use the select clause to pick out an object which matches a specified name field from a database query as follows: objectQuery = from obj in objectList where obj.Equals(objectName) select obj; In the results view of my query, I get: base {System.SystemException} = {"Boolean Equals(System.Object)"} Where I should be expecting something like a Car, Make, or Model Would someone please explain what I am doing wrong here? The method in question can be seen here: // this function searches the database's table for a single object that matches the 'Name' property with 'objectName' public static T Read<T>(string objectName) where T : IEquatable<T> { using (ISession session = NHibernateHelper.OpenSession()) { IQueryable<T> objectList = session.Query<T>(); // pull (query) all the objects from the table in the database int count = objectList.Count(); // return the number of objects in the table // alternative: int count = makeList.Count<T>(); IQueryable<T> objectQuery = null; // create a reference for our queryable list of objects T foundObject = default(T); // create an object reference for our found object if (count > 0) { // give me all objects that have a name that matches 'objectName' and store them in 'objectQuery' objectQuery = from obj in objectList where obj.Equals(objectName) select obj; // make sure that 'objectQuery' has only one object in it try { foundObject = (T)objectQuery.Single(); } catch { return default(T); } // output some information to the console (output screen) Console.WriteLine("Read Make: " + foundObject.ToString()); } // pass the reference of the found object on to whoever asked for it return foundObject; } } Note that I am using the interface "IQuatable<T>" in my method descriptor. An example of the classes I am trying to pull from the database is: public class Make: IEquatable<Make> { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IList<Model> Models { get; set; } public Make() { // this public no-argument constructor is required for NHibernate } public Make(string makeName) { this.Name = makeName; } public override string ToString() { return Name; } // Implementation of IEquatable<T> interface public virtual bool Equals(Make make) { if (this.Id == make.Id) { return true; } else { return false; } } // Implementation of IEquatable<T> interface public virtual bool Equals(String name) { if (this.Name.Equals(name)) { return true; } else { return false; } } } And the interface is described simply as: public interface IEquatable<T> { bool Equals(T obj); }

  • NTFS Error - file system structure is corrupt and unusable

    - by SomeGuy
    My Windows 7 (64) keeps completely locking up, and I have to hold the power button to shit it down. Event logs are showing EventID 55. I realize that this can be a warning sign of an impending disk failure, but my data on this machine is safely backed up and I don't feel like taking the time to replace the drive right now. When I have seen this problem before, I have been able to delete the offending folder with a Linux Live CD. (When CHKDSK /F didn't work). In this case, the folder is from VSS. I assume this is from Crashplan, my online backup provider. What are the ramifications of deleting this folder from Linux? Is it safe to do? "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy26."

  • Weird (?) issue with Exchange Forwarding

    - by abszero
    Hello everyone. Here is the long and short of it: the company I work for was purchased by another company who uses Gmail for domains as their email provider. We use an in house Exchange box. No big deal, I dropped into Active Directoy and created several Contact objects that represented our new email addresses at Gmail. I then went through each employees record and have their mail set to forward to this new address and not deliver locally. So I am forwarding email for me@domain1 to me@domain2 and this works great as long as I don't send an email from me@domain2 to me@domain1. If I log into my personal Gmail account and send an email to me@domain1 the email is properly forwarded to me@domain2. The mail coming from me@domain2 to me@domain1 seems to just get lost in the ether. Have I done something wrong or is this a quark with Exchange? Thanks!

  • Backup and restore MySQL database without system access

    - by Sencerd
    Hi guys, I am trying to move a database from 1 provider to another, the problem is that I don't have system access at either end (ie, no ssh), so I cannot use a mysqldump. I have already tried using MySQL Administrator, the backup took about 45 minutes, but when it came to restoring it was moving at a snails pace, and estimating 12+ hours. This is a live app so I need to keep the downtime to an absolute minimum. The database consists of 35 tables, a mixture of MyISAM and InnoDB, the whole thing comes to about 4.4GB. The source and destination databases are both running on very powerful servers. Any suggestions on a quick way of doing this will be gratefully received. Thanks

  • Embedding a scripting engine in C++

    - by Jen
    I'm researching how to best extend a C++ application with scripting capability, and I am looking at either Python or JavaScript. User-defined scripts will need the ability to access the application's data model. Have any of you had experiences with embedding these scripting engines? What are some potential pitfalls?

  • EF exception: Could not find file CodeGenerationSchema.xsd

    - by DK
    I'm using Entity Framework for a new project (VS 2008, .net 3.5 sp1) and "reasonably happy" with it, especially compared to dataset-based solutions. One of recurring annoyances is "Could not find file CodeGenerationSchema.xsd" exception during application startup. Exception seems to re-appear rather frequently after changes to the model. Googling gives temporary and strange workarounds for this error: Delete .suo file, or Set Options Debugging General Enable Just My Code = On May be someone have more permanent, straightforward fix or can explain the reason of this issue.

  • newbie problems with codeigniter

    - by Patrick
    hi, i'm trying to learn codeigniter (following a book) but don't understand why the web page comes out empty. my controller is class Welcome extends Controller { function Welcome() { parent::Controller(); } function index() { $data['title'] = "Welcome to Claudia's Kids"; $data['navlist'] = $this->MCats->getCategoriesNav(); $data['mainf'] = $this->MProducts->getMainFeature(); $skip = $data['mainf']['id']; $data['sidef'] = $this->MProducts->getRandomProducts(3, $skip); $data['main'] = "home"; $this->load->vars($data); $this->load->view('template'); } the view is: <--doctype declaration etc etc.. --> </head> <body> <div id="wrapper"> <div id="header"> <?php $this->load->view('header');?> </div> <div id='nav'> <?php $this->load->view('navigation');?> </div> <div id="main"> <?php $this->load->view($main);?> </div> <div id="footer"> <?php $this->load->view('footer');?> </div> </div> </body> </html> Now I know the model is passing back the right variables, but the page appears completely blank. I would expect at least to see an error, or the basic html structure, but the page is just empty. Moreover, the controller doesn't work even if I modify it as follows: function index() { echo "hello."; } What am I doing wrong? Everything was working until I made some changes to the model - but even if I delete all those new changes, the page is still blank.. i'm really confused! thanks, P.

  • Is it possible ot mix named pipe with select in perl

    I need to write a daemon that supposed to have one TCP socket and one named pipe. Usually if I need to implement a multi IO server with "pure" sockets, the select based multi-IO model is always the one I will choose. so does anyone of you have ever used named pipe in select or you can just tell me it is impossible. thanks in advance.

  • Connect ADSL modem SMC7904WBRA-N to CISCO RV082

    - by Cy.
    I have a SMC7904WBRA-N ADSL modem/router that connects to the internet with a static IP given by the provider. I've received a RV082 to create a VPN connection which is having problems to connect to the remote VPN Server. After many tries we deduced that the SMC7904WBRA-N is being problematic with the NAT and I have been suggested to put the SMC router into the appropriate DSL bridging mode so the RV082 gets direct access to internet with the static IP. Can you give me any hints on how could this be done? Which mode is that?
