  • SQL is this equivalent to a LEFT JoIn?

    - by Jim
    Is this equivalent to a LEFT JOIN? SELECT DISTINCT a.name, b.name FROM tableA a, (SELECT DISTINCT name FROM tableB) as b It seems as though there is no link between the two tables. Is there an easier / more efficient way to write this?

  • Struts 2: redirect-action ? From on page to another and back again.

    - by Stephan
    Hello, i have a jsp page that has a submit button. This button is linked with another jsp page. So lets assume my stuts file looks like this: B.jsp So now the submit button being on page "A.jsp" will take me to B.jsp. This works. The problem is that i want to do the following: press on the submit button on page A.jsp , go to B.jsp where i will press again a button and go back to A.jsp . The problem is that to page B.jsp go many pages, so B.jsp has to know when pressing the submit button to which page will take me back , in this case A.jsp again. So in a few words, B.jsp has to know from which page i came from so that i can go back again by pressing a submit button (this could be a parameter that would be sent back to A.jsp again, but does not really matter at the current point) A.jsp - B.jsp - A.jsp C.jsp - B.jsp - C.jsp

  • 'Caching' a large table in ASP.NET

    - by TheNewGuy
    I understand that each page refresh, especially in 'AjaxLand', causes my back-end/code-behind class to be called from scratch... This is a problem because my class (which is a member object in System.Web.UI.Page) contains A LOT of data that it sources from a database. So now every page refresh in AjaxLand is causing me to making large backend DB calls, rather than just to reuse a class object from memory. Any fix for this? Is this where session variables come into play? Are session variables the only option I have to retain an object in memory that is linked to a single-user and a single-session instance?

  • How to display HTML-like table data on iPhone?

    - by Jason
    I have a set of data in a matrix which I would like to display in my iPhone app with all of the rows and columns intact. Everything I can find on the web dealing with "tables iPhone" gives me information on UITableView, which only lets you show a list of items to the user - not an actual table in the HTML sense. What's the best way on the iPhone to display an actual table of data to the user, with column & row headings and table cells?

  • How do I generate Entity Framework 4.0 classes from the command line that have different names than

    - by Josh Kodroff
    I want to generate Entity Framework 4.0 classes from a (legacy) database from a command line, but I have 2 transformations I want: Tables/columns are lowerCamelCase and I want my classes/members to be UpperCamelCase. I want to suffix my classes with "Dto". Any idea how this might be accomplished? I'm a total newbie to EF, but I have a decent understanding of Linq to Sql and was able to accomplish the same task by doing: sqlmetal - dbml - xml mapping file and .cs file.

  • MySQL - Limit a left join to the first date-time that occurs?

    - by John M
    Simplified table structure (the tables can't be merged at this time): TableA: dts_received (datetime) dts_completed (datetime) task_a (varchar) TableB: dts_started (datetime) task_b (varchar) What I would like to do is determine how long a task took to complete. The join parameter would be something like ON task_a = task_b AND dts_completed < dts_started The issue is that there may be multiple date-times that occur after the dts_completed. How do I create a join that only returns the first tableB-datetime that occurs after the tableA-datetime?

  • Convert Object Hierachey to Object Array

    - by Killercam
    All, I want to create an object array foo[], where the constructor for Foo is public Foo(string name, string discription){} I have a database object which has a structure (not incuding stored procedures, functions or views for simplicity) like public class Database { public string name { get; set; } public string filename { get; set; } public List<Table> tables { get; set; } public Database(string name, string filename) { this.name = name; this.filename = filename; } } protected internal class Table { public string name { get; set; } public List<Column> columns { get; set;} public Table(string name, List<Column> columns) { this.name = name; this.columns = columns; } } protected internal class Column { public string name { get; set; } public string type { get; set; } public Column(string name, string type, int maxLength, bool isNullable) { this.name = name; this.type = type; } } I would like to know the quickest way to add Column and Table information to the Foo[] object array? Clearly I can do List<Foo> fooList = new List<Foo>(); foreach (Table t in database.tables) { fooList.Add(new Foo(t.Name, "Some Description")); foreach (Column c in t.columns) fooList.Add(new Foo(c.Name, "Some Description")); } Foo[] fooArr = fooList.ToArray<Foo>(); But is there a quicker way? Clearly LINQ is likely to be slower for a query that does a simalar operation, but I care allot about speed here so any advice would be appreciated. Perhaps the use of a HashSet would be the way to go as there will not be duplicate entries... Thanks for your time.

  • Creative Technical Interview Questions for Developers

    - by John Shedletsky
    I do a good number of in-person technical interviews for new developers. I like to ask technical questions where I ask people to either code something up or develop an algorithm to solve a task. I feel my current repertoire is uninspired. In my opinion, the ideal interview question has these qualities: Multiple solutions, where some are obviously better than others, and some that involve subtle trade-offs (discussing tradeoffs is a good way to gauge someone's experience, in my opinion). Novelty - asking the "insert this element into a linked list" question is only good for weeding out people who never did their homework. Elegant - I like questions where the core problem isn't hidden in a lot of details. Everyone should be able to understand the problem, even if everyone can't solve it on the whiteboard. Elegant questions are difficult without involving undue amounts of "domain knowledge" or getting too narrow. Have you been on either side of an interview where someone (maybe you!) asked a particularly good programming or algorithms question?

  • Version control PHP Web Project

    - by Adam Lerman
    We have a php project that we would like to version control. Right now there are three of us working on a "Dev" version of the project that all have our Eclipse linked to it with just an external folder, and thus no version control. What is the right way, and what is the best way, to version control this (not necessarily the same I dont think) We have a SVN set up but just need to find a good way to check in and check out that lets us test on the dev server. Any ideas?

  • Why did this code still work?

    - by bstullkid
    Some old code that I just came across: MLIST * new_mlist_link() { MLIST *new_link = (MLIST * ) malloc(sizeof(MLIST)); new_link->next = NULL; new_link->mapi = NULL; new_link->result = 0; } This was being called to build a linked list, however I noticed there is no statement: return new_link; Even without the return statement there, the list still got built properly. Why did this happen? EDT: Platform: Mandriva 2009 64bit Linux 2.6.24.7-server GCC 4.2.3-6mnb1

  • NoSQL vs Relational Coding Styles

    - by Chris Henry
    When building objects that make use of data stored in a RDBMS, it's normally pretty clear what you're getting back, as dictated by the tables and columns being queried. However, when dealing with NoSQL, document-based systems, it's less clear what is being retrieved. What are common methods of keeping track of structure in which data is stored?

  • ZF Site in ZF Site? How do I redirect form subdirectory to another subdirecotry?

    - by AD
    The deal is that I have a ZF site for which root directory is /public. How should I go about redirecting to a subdirectory if I want to do next? I want to have another subdirectory under /public/ that would not be linked to a main website in any way except it using save ZF. Lets say I have this: /public/newsite/ which will include a complete modular ZF (just I have it for the main site). That is the root directory for the NEWSITE would be /public/newsite/public. So my question how do I modify my .htaccess rules so it would redirect any requests from /public/newsite/ to /public/newsite/public/? Thank you in advance.

  • C# LINQ join With Just One Row

    - by Soo
    I'm trying to make a query that grabs a single row from an SQL database and updates it. TableA AId AValue TableB BId AId BValue Ok, so TableA and TableB are linked by AId. I want to select a row in TableB based on AValue using a join. The following query is what I have and only grabs a value from TableB based on AId, I just don't know how to grab a row from TableB using AValue. I know you would need to use a join, but I'm not sure how to accomplish that. var row = DbObject.TableB.Single(x => x.AId == 1) row.BValue = 1; DbObject.SubmitChanges();
