  • Why was this T-SQL Syntax never implemented?

    - by ChrisA
    Why did they never let us do this sort of thing: Create Proc RunParameterisedSelect @tableName varchar(100), @columnName varchar(100), @value varchar(100) as select * from @tableName where @columnName = @value You can use @value as a parameter, obviously, and you can achieve the whole thing with dynamic SQL, but creating it is invariably a pain. So why didn't they make it part of the language in some way, rather than forcing you to EXEC(@sql)?

  • SQL. Sorting by a field

    - by strakastroukas
    I have created a simple view consisting of 3 tables in SQL. By right clicking and selecting Design, in the Object explorer table, i modified my custom view. I just added sortby asc in a field. The problem is that the changes are not reflected in the outout of the View. After saving the view, and selecting Open view the sort is not displayed in output. So what is going on here?

  • What causes POCO proxy entities to only sometimes be created in Entity Framework 4.

    - by Kohan
    I have set up my POCOs and I have marked their public properties as virtual and I am successfully getting Proxies most of the time (95%) but randomly I am getting EF return some proxies and some non-proxies. Recycling the app pool when this happens will then fix this instance of the error and it will go away for an amount of time. Then it will re-occur in some other random (it seems) place. What can cause this sort of behaviour? Thanks, Kohan

  • Adding additional sorting attributes to array of records...then sorting!

    - by keruilin
    Let's say I run an ActiveRecord query and it returns 3 results, with a bunch of attributes. I want to add 3 attributes to each record in the Array so I can do sorting at a code-level. These 3 include: num_comments, num_views, last_view. How do I add these attributes? How do I then sort the records, in order of precendence, by num_comments AND by num_views AND by last_view?

  • What can you do in C without "std" includes? Are they part of "C," or just libraries?

    - by Chris Cooper
    I apologize if this is a subjective or repeated question. It's sort of awkward to search for, so I wasn't sure what terms to include. What I'd like to know is what the basic foundation tools/functions are in C when you don't include standard libraries like stdio and stdlib. What could I do if there's no printf(), fopen(), etc? Also, are those libraries technically part of the "C" language, or are they just very useful and effectively essential libraries?

  • What can you do and not do with java annotations?

    - by swampsjohn
    The typical use-case is for simple things like @Override, but clearly you can do a lot more with them. If you push the limits of them, you get things like Project Lombok, though my understanding is that that's a huge abuse of annotations. What exactly can you do? What sort of things can you do at compile-time and run-time with annotations? What can you not do?

  • Sorting string column containing numbers in SQL?

    - by Ish
    Dear Folks, I am trying to sort string column (containing numbers). // SELECT `name` FROM `mytable` ORDER BY `name` ASC +----------+ +-- name --+ +----------+ +-- a 1 ---+ +-- a 12 --+ +-- a 2 ---+ +-- a 3 ---+ You see natural sorting algorithm of Mysql is placing a 12 after a 1 (which is ok for most apps), But I have unique needs, so I want result should be sorted like this. +----------+ +-- name --+ +----------+ +-- a 1 ---+ +-- a 2 ---+ +-- a 3 ---+ +-- a 12 --+ Is it possible with just SQL, or I have to manipulate result-set at application level? Thanks for reading...

  • Add Shortcut to Nested Route

    - by wakeless
    I'm using nested routes and I want to provide some sort of a shortcut method. (I'm using RoR 3.0) The routes look like this. resources :countries do resources :regions do resources :wineries end end To access a winery route I want to be able to define a function that removes the need to specify a country and region each time. Like: def winery_path(winery) country_region_winery_path (winery.country, winery.region, winery) end Where should I do this? How can I get that to be available whereever url_for is available?

  • Creating a Calender in PHP

    Are there any APIs/Libraries that make it easy to generate a calender for a certain month/year? I need to have some sort of admin interface for a "event planner" part of a CMS for a local youth group and I'm at a loss as to how to generate a decent calender.

  • Microsoft Small Business Licensing Kick Start

    - by regex
    I seem to recall hearing at some point (I believe it was MIX09) that Microsoft has a licensing model of some sort where a business can consume licenses for up to two years, free of charge, until they reach a point where they are stable position and can pay their licensing at the end of two years. However, I can't find information regarding it online. I want to say that possibly stackoverflow used this licensing model to kick start their site. Is anyone familiar with this?

  • Do graphic cards have instruction sets of their own?

    - by Matt
    Do graphic cards have instruction sets of their own? I assume they do, but I have been wondering if it is proprietary or if there is some sort of open standard. Is every GPU instruction preceded by a CPU instruction or is it seamless? That is does OpenGL or DirectX call on the driver layer via the CPU which then sends a GPU instruction down the bus or is it more elaborate.

  • How to avoid strange characters before the request in firefox?

    - by murze
    Hi, on a website i'm currently developing I'm using jquery to do all sort of magic things :-) In firefox however, when I load jquery 1.4.2 there are sometimes funny characters in front of the request. You can see the strangers characters in this screenshot (thank you firebug). In safari, Chrome and IE these funny characters don't appear, jquery is loading fine in those browsers. Why are those characters appearing and how can I remove them? Thanks!!

  • What does capital W do in VIM?

    - by tesmar
    Hi, in VIM sometimes when saving, I accidentally hit capital W instead of its lowercase brother. I am prompted for my system password, so I assume it is running a sudo command of some sort, but do you know what? Thank you!

  • Boost Serialization Library upgrade

    - by Konstantin
    Hello! How do I know that I can safely upgrade Boost Serialization Library on a production system without breaking compatibility with the existing data ? Is there any test that I should perform in order to be sure that all data stored in the binary format by previous version of the library will be successfully read by the new one ? Does Boost Serialization library itself guarantee some sort of compatibility between versions ?

  • I want to know when a file is down downloading

    - by paulj3000
    Hi, I have a file which I want users to download only once. After it's done downloading, the file is no longer available. Outside of setting up a streaming system, is there any way I can set some sort of callback up to say the file is done downloading on the client's computer? Thanks

  • Why do I get so many errors building my Android project with Ant?

    - by synic
    Now that I sort of know my way around the SDK/API, I've switched from Eclipse back to my favorite text editor, which means I have to use ant to build my project, however: It seems every other time I compile the project, a lot of drawables get corrupted, resources lose their ids (resulting in NPEs in the code), or classes throw "Verify Errors". The only way to fix this is by removing the bin and gen folders, and recompiling, which is obviously annoying. Is there any way to avoid this? btw, I'm using ant 1.7.1, java version "1.6.0_20"
