  • issue with selecting 1 or 0 in mysql db

    - by jason
    I am having trouble with the following SQL statement i have had this issue before but I cant remember how i fixed the problem, I am guessing the issue with this is that mysql sees 0 as null ? Note I didnt show the first part of the Select statement as its irrelevant my sql works, its showing rows with toffline that are = to 1 as well as 0... FROM table1 AS tb1 LEFT JOIN table2 AS tb2 ON tb2.id = tb1.id2 LEFT JOIN table3 AS tb3 ON tb3.id = tb1.id3 AND tb1.toffline = 0 I have also tried AND NOT tb1.toffline = 1 also WHERE tb1.toffline = 0 all with the same result...

  • data loading - app launching on tableview

    - by wallou
    hi, i encounter an issue with my application. On one hand when my app launches, the first view displayed is a tableview within a tableviewcontroller. On the other hand my app calls a web service to collect data. These methods are in MyAppDelegate\applicationDidFinishLaunching. The thing is that my tableview is made of custom cells that need data from the web service. I noticed that the view (with the tableview) is launched first and then MyAppDelegate\applicationDidFinishLaunchin is executed. As a result the labels of my custom cells are all equal to null as my arrays aren't filled yet by the web service. I would like to know the proper way to make it. If anyone has an idea please tell me. Wallou

    - by tamara
    I am trying to implemet django-updown https://github.com/weluse/django-updown. When I try to add vote trough the admin panel it says Value 1 not a valid choice.

  • Entity Framework 5 not updating navigation properties in both entities

    - by Taylor
    I have updated a project to use the new Entity framework shipped with VS2012, however I have run into some of my code throwing exceptions. In the VS10 version of EF I was able to create or modify and Entity and use its navigation properties before calling SaveChanges() For example: A Navigation property of a client having a collection of Invoices. Client c = new Client(); Invoice I = new Invoice(); c.Invoices.Add(I); I would then be able to use Invoice.Client somewhere in my code before actually saving it without issue. Now Invoice.Client == null. Similarly in setting I.Client = C, I does not show up under C.Invoices What am I missing here or is this just simply how EF5 is?

    - by Sjemmie
    I'm working on SQL server 2005 and I have a very simple stored procedure: create PROCEDURE [dbo].[tblTabel_Insert] @ID int, @Code nvarchar(50) = null AS SET NOCOUNT ON; IF EXISTS (SELECT ID, code FROM tblTabel WHERE ID = @ID and code = @Code) UPDATE tblTabel SET ID = @ID,code = @Code WHERE ID = @ID ELSE BEGIN INSERT INTO tblTabel (ID,code) VALUES ( @ID ,@Code); END My question is: is it posible to have multiple queries in my stored procedure ? I want to add the lines UPDATE tblTabelB SET ID = @ID,code = @Code WHERE ID = @ID UPDATE tblTabelC SET ID = @ID,code = @Code WHERE ID = @ID in my if exists section. How do I change my stored procedure in the correct way ?

  • Getting deadlocks in MySQL

    - by at
    We're very frustratingly getting deadlocks in MySQL. It isn't because of exceeding a lock timeout as the deadlocks happen instantly when they do happen. Here's the SQL code that is executing on 2 separate threads (with 2 separate connections from the connection pool) that produces a deadlock: UPDATE Sequences SET Counter = LAST_INSERT_ID(Counter + 1) WHERE Sequence IS NULL Sequences table has 2 columns: Sequence and Counter The LAST_INSERT_ID allows us to retrieve this updated counter value as per MySQL's recommendation. That works perfect for us, but we get these deadlocks! Why are we getting them and how can we avoid them?? Thanks so much for any help with this.

  • Passing dynamic parameter to a JavaScript function using innerHTML

    - by user958263
    I am having issues passing a dynamic parameter to a JavaScript function using innerHTML. Included below is the current code that I am using: var name = "test"; frm.innerHtml = '<button name="close" id="close" title="Cancel" type="button" onclick="closeTab('+name+');">Return</button>'; When I debug the code of the CloseTab() function, the parameter specified by the name variable is null. I believe there is a problem with the declaration of the value while modifying the innerHTML property. Any help would be greatly appreciated. Thanks

  • Is possible to remove an event listener in actionscript 3 (flash) ??

    - by DomingoSL
    In the frame 1 of my movie, part of my code is: stage.addEventListener(Event.RESIZE, resizeHandler); It works all fine, but when i go to the frame 2 the listener is still there but the function resizeHandler is not anymore (and i dont want it). So the console output this: TypeError: Error #1009: Cannot access a property or method of a null object reference. at index_fla::MainTimeline/resizeHandler() at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at flash.display::Stage/dispatchEvent() at index_fla::MainTimeline/frame2() Is possible to remove the event listener on the frame 2? Thanks!!!

  • Many Buttons on a Page, Need to send back Unique Post Data with each

    - by CoffeeAddict
    I'm listing out a bunch of cars with a button next to them that when clicked will need to perform a GET but also sends over that item's model.Name: @using (Html.BeginForm("GetCarUrl", "Car", FormMethod.Get, new { model = Model })) { if(Model.Cars != null && Model.Cars.Count > 0) { foreach (CarContent car in Model.Cars) { <p>@car.Name</p> } <input type="button" value="Get Car Url" class="submit" /> } So the page renders a bunch of hyperlinks and buttons: [hyperlink1] [submit] [hyperlink2] [submit] [hyperlink3] [submit] [hyperlink4] [submit] [hyperlink5] [submit] ... When a user clicks on any of the submits, I need to pass back its corresponding @car.CarType for that specific hyperlink Not sure how to go about this. My action method expects a @car.CarType for that specific car hyperlink to be sent to it

  • Append an onClick event to an anchor tag using jquery?

    - by M.Woodard
    I am trying to add an onClick event to an anchor tag ... Previously i had ... <a href="somlink.html" onClick="pageTracker._link(this.href); return false;"> But i am trying to avoid the inline onClick event because it interferes with another script.. So using jQuery i am trying the following code ... <script> $(document).ready(function() { $('a#tracked').attr('onClick').click(function() {window.onbeforeunload = null; pageTracker._link(this.href); return false; }); }); </script> with the html like so <a id="tracked" href="something.html"> So my question is should this be working, and if not what would be the best solution?

  • Using Option all over the place feels a bit awkward. Am I doing something wrong?

    - by Geo
    As a result of articles I read about the Option class which helps you avoid NullPointerException's, I started to use it all over the place. Imagine something like this: var file:Option[File] = None and later when I use it: val actualFile = file.getOrElse(new File("nonexisting")) if(actualFile.getName.equals("nonexisting")) { // instead of null checking } else { // value of file was good } Doing stuff like this doesn't feel all that "right" to me. I also noticed that .get has become deprecated. . Is this sort of stuff what you guys are doing with Option's too, or am I going the wrong way?

  • If item not in the lst in scheme

    - by ms. sakura
    I'm working on context-free grammars, and I have a function that returns the (terminal values of grammar) for example: i have non-terminal function that results in (A B) , from calling say ((A cat) (B happy np) (A B sad)) so technically A and B are non terminals of the grammar. Now I want to be able to get the terminals (cat happy np sad) (define terminals (lambda (lsts) (cond ((null? lsts) lsts) ((not(member? (car(car lsts)) (n-terminals lsts))) (cons (car(car lsts)) (terminals (car (cdr lsts))))) (else (terminals (cdr lsts)))))) PS: functionality of n-terminals is described above. member? is a boolean function that returns true if an item is a member of the list, false otherwise. My function returns an empty lst. What am I missing here?

  • SQLite issues, escaping certain characters...

    - by CODe
    I'm working on my first database application. It is a WinForms application written in C# using a SQLite database. I've come across some problems, when a apostrophe is used, my SQLite query fails. Here is the structure of my queries. string SQL = "UPDATE SUBCONTRACTOR SET JobSite = NULL WHERE JobSite = '" + jobSite + "'"; For instance, if an apostrophe is used in the jobSite var, it offsets the other apostrophes in the command, and fails. So my questions are: 1. How do I escape characters like the apostrophe and semicolon in the above query example? 2. What characters do I need to escape? I know I should escape the apostrophe, what else is dangerous? Thanks for your help!
