• SQL - Select all when filter value is empty

  - by iansinke

  I have a SQL query in my ASP.net web app that looks like this: SELECT * FROM [Records] WHERE ([title] LIKE '%' + @title + '%') @title, of course, is the value of a text box on the page. My question is, why, when the text box is empty, does this return nothing? And how can I make it return everything, like logic tells me it ought to?

• Convert a value based on range

  - by Chris

  I need to convert a number to another value based on a range: ie: 7 = "A" 106 = "I" I have a range like this: from to return-val 1 17 A 17 35 B 35 38 C 38 56 D 56 72 E 72 88 F 88 98 G 98 104 H 104 115 I 115 120 J 120 123 K 123 129 L 129 infinity M The values are fixed and do not change. I was thinking a lookup table would be required, but is there a way it could be done with a function on an analytics function inside of oracle?

• Get Auto Increment value with MySQL query

  - by James Simpson

  I currently have a database with over 6 million rows and growing. I currently do SELECT COUNT(id) FROM table; in order to display the number to my users, but the database is getting large and I have no need to store all of those rows except to be able to show the number. Is there a way to select the auto_increment value to display so that I can clear out most of the rows in the database? Using LAST_INSERT_ID() doesn't seem to work.

• C# function normal return value VS out or ref argument

  - by misha-r

  Hi People, I've got a method in c# that needs to return a very large array (or any other large data structure for that matter). Is there a performance gain in using a ref or out parameter instead of the standard return value? I.e. is there any performance or other gain in using void function(sometype input, ref largearray) over largearray function(sometype input) ? Thanks in advance!

• Getting a specific bit value in a byte string

  - by ignoramus

  There is a byte at a specific index in a byte string which represents eight flags; one flag per bit in the byte. If a flag is set, its corresponding bit is 1, otherwise its 0. For example, if I've got b'\x21' the flags would be 0001 0101 # Three flags are set at indexes 3, 5 and 7 # and the others are not set What would be the best way to get each bit value in that byte, so I know whether a particular flag is set or not? (Preferably using bitwise operations)

• C# mvc 3 using selectlist with selected value in view

  - by Rob

  I'm working on a MVC3 web application. I want a list of categories shown when editing a blo from whe applications managements system. In my viewmodel i've got the following property defined for a list of selectlistitems for categories. /// <summary> /// The List of categories /// </summary> [Display(Name = "Categorie")] public IEnumerable<SelectListItem> Categories { get; set; } The next step, my controller contains the following edit action where the list of selectlistitems is filled from the database. public ActionResult Edit(Guid id) { var blogToEdit = _blogService.First(x => x.Id.Equals(id)); var listOfCategories = _categorieService.GetAll(); var selectList = listOfCategories.Select(x =>new SelectListItem{Text = x.Name, Value = x.Id.ToString(), Selected = x.Id.Equals(blogToEdit.Category.Id)}).ToList(); selectList.Insert(0, new SelectListItem{Text = Messages.SelectAnItem, Value = Messages.SelectAnItem}); var viewModel = new BlogModel { BlogId = blogToEdit.Id, Active = blogToEdit.Actief, Content = blogToEdit.Text, Title = blogToEdit.Titel, Categories = selectList //at this point i see the expected item being selected //Categories = new IEnumerable<SelectListItem>(listOfCategories, "Id", "Naam", blogToEdit.CategorieId) }; return View(viewModel); } When i set a breakpoint just before the view is being returned, i see that the selectlist is filled as i expected. So at this point everything seems to be okay. The viewmodel is filled entirely correct. Then in my view (i'm using Razor) i've got the following two rules which are supposed to render the selectlist for me. @Html.LabelFor(m => m.Categories) @Html.DropDownListFor(model=>model.Categories, Model.Categories, Model.CategoryId) @Html.ValidationMessageFor(m => m.Categories) When I run the code and open the view to edit my blog, I can see all the correct data. Also the selectlist is rendered correctly, but the item i want to be selected lost it's selection. How can this be? Until the point the viewmodel is being returned with the view everything is okay. But when i view the webpage in the browser, the selectlist is there only with out the correct selection. What am I missing here? Or doing wrong?
