• classic asp - response.redirect and response.write problem

  - by apg1985

  Hi People, The problem if someone types into the search box a location it goes through to that location page but if they type in a location thats not found or they dont type anything in I need it to redirect back to the homepage (index.asp) and display "whoops we couldnt find that" in the search box (input field) This is the vb Case Else response.redirect "index.asp?whoops=whoops we couldnt find that" End Select Then in the value of the input field I have value="<% =whoops %>" This doesnt work by the way, first is this the best way of doing it because id rather not have the error message in the url. This there away of posting the error as a variable and then calling it into the input field like, <% =whoops %>

• noSQL/SQL/RoR: Trying to build scalable ratings table for the game

  - by alexeypro

  I am trying to solve complex thing (as it looks to me). I have next entities: PLAYER (few of them, with names like "John", "Peter", etc.). Each has unique ID. For simplicity let's think it's their name. GAME (few of them, say named "Hide and Seek", "Jump and Run", etc.). Same - each has unique ID. For simplicity of the case let it be it's name for now. SCORE (it's numeric). So, how it works. Each PLAYER can play in multiple GAMES. He gets some SCORE in every GAME. I need to build rating table -- and not one! Table #1: most played GAMES Table #2: best PLAYERS in all games (say the total SCORE in every GAME). Table #3: best PLAYERS per GAME (by SCORE in particularly that GAME). I could be build something straight right away, but that will not work. I will have more than 10,000 players; and 15 games, which will grow for sure. Score can be as low as 0, and as high as 1,000,000 (not sure if higher is possible at this moment) for player in the game. So I really need some relative data. Any suggestions? I am planning to do it with SQL, but may be just using it for key-value storage; anything -- any ideas are welcome. Thank you!

• Merge replication server side foreign key violation from unpublished table

  - by Reiste

  We are using SQL Server 2005 Merge Replication with SQL CE 3.5 clients. We are using partitions with filtering for the separate subscriptions, and nHibernate for the ORM mapping. There is automatic ID range management from SQL Server for the subscriptions. We have a table, Item, and a table with a foreign key to Item - ItemHistory. Both of these are replicated down, filtered according to the subscription. Item has a column called UserId, and is filtered per subscription with this filter: WHERE UserId IN (SELECT... [complicated subselect]...) ItemHistory hangs off Item in the publication filter articles. On the server, we have a table ItemHistoryExport, which has a foreign key to ItemHistory. ItemHistoryExport is not published. Entries in the Item and ItemHistory tables are never deleted, on the server or the client. However, the "ownership" of items (and hence their ItemHistories) MAY change, which causes them to be moved from one client subscription/partition to another from time to time. When we sync, we occasionally get the following error: A row delete at '48269404 - 4108383dbb11' could not be propagated to 'MyServer\MyInstance.MyDatabase'. This failure can be caused by a constraint violation. The DELETE statement conflicted with the REFERENCE constraint "FK_ItemHistoryExport_ItemHistory". The conflict occurred in database "MyDatabase", table "dbo.ItemHistoryExport", column 'ItemHistoryId'. Can anyone help us understand why this happens? There shouldn't ever be a delete happening on the server side.

• Zend Framework :: extending action variable scope for partials

  - by dev-drupal

  Hi, I want to know if there exist any other way through which we can access the controller name, action name and other variables inside a partial. In other words, I want to extend the scope of my action variable to be accessed inside the partial templates rather than passing the lot along with the call to partial template. Thanks -DevD.

• Variable naming for arrays - C#

  - by David Neale

  What should I call a variable instantiated with some type of array? Is it okay to simply use a pluralised form of the type being held? IList<Person> people = new List<Person>(); or should I append something like 'List' to the name? IList<Person> personList = new List<Person>();

• should this database table be normalized?

  - by oo

  i have taken over a database that stores fitness information and we were having a debate about a certain table and whether it should stay as one table or get broken up into three tables. Today, there is one table called: workouts that has the following fields id, exercise_id, reps, weight, date, person_id So if i did 2 sets of 3 different exercises on one day, i would have 6 records in that table for that day. for example: id, exercise_id, reps, weight, date, person_id 1, 1, 10, 100, 1/1/2010, 10 2, 1, 10, 100, 1/1/2010, 10 3, 1, 10, 100, 1/1/2010, 10 4, 2, 10, 100, 1/1/2010, 10 5, 2, 10, 100, 1/1/2010, 10 6, 2, 10, 100, 1/1/2010, 10 So the question is, given that there is some redundant data (date, personid, exercise_id) in multiple records, should this be normalized to three tables WorkoutSummary: - id - date - person_id WorkoutExercise: - id - workout_id (foreign key into WorkoutSummary) - exercise_id WorkoutSets: - id - workout_exercise_id (foreign key into WorkoutExercise) - reps - weight I would guess the downside is that the queries would be slower after this refactoring as now we would need to join 3 tables to do the same query that had no joins before. The benefit of the refactoring allows up in the future to add new fields at the workout summary level or the exercise level with out adding in more duplication. any feedback on this debate?

• Objective C: Initalizing static variable with static method call

  - by adranale

  The Compiler claims an error saying: "initializer element is not constant", when I try to initialize a static variable inside a method with a call to a static method (with + in its definition). Anyway I can tell him that this method always returns the same value. I know this is not the same as static method, but there seems to be no constant methods in Objective-C (other than macros which won't work here because I am calling UI_USER_INTERFACE_IDIOM() from inside the method).

• C stack/scope, variable's lifetime after functions ends

  - by Ranking Stackingblocks

  void someFunc() { int stackInt = 4; someOtherFunc(&stackInt); } Is it the case that stackInt's address space could be reallocated after someFunc ends, making it unsafe to assume that the value passed to someOtherFunc represents the stackInt variable with value 4 that was passed to it? In other words, should I avoid passing stack variables around by address and expecting them to still be alive after the function they were initialised in has ended?

• Collaboration Diagrams: how to represent setting a variable's and attribute's value to a specified v

  - by devoured elysium

  Let's assume I have a class called MyClass with an attribute called MyAttribute and a method called MyMethod(). Inside that method I'd like to have a variable called MyVariable. I'd like to set the value of MyVariable to "MyVariable" and MyAttribute to "MyAttribute" inside the call to MyMethod(). How can I do this in a Collaboration Diagram? I can't find any info of this kind on the internet and the book I'm studying from (Applying UML and Patterns) is very vague in the details. Thanks

• SQL database problems with addressbook table design

  - by Sebastian Hoitz

  Hello! I am writing a addressbook module for my software right now. I have the database set up so far that it supports a very flexible address-book configuration. I can create n-entries for every type I want. Type means here data like 'email', 'address', 'telephone' etc. I have a table named 'contact_profiles'. This only has two columns: id Primary key date_created DATETIME And then there is a table called contact_attributes. This one is a little more complex: id PK #profile (Foreign key to contact_profiles.id) type VARCHAR describing the type of the entry (name, email, phone, fax, website, ...) I should probably change this to a SET later. value Text (containing the value for the attribute). I can now link to these profiles, for example from my user's table. But from here I run into problems. At the moment I would have to create a JOIN for each value that I want to retrieve. Is there a possibility to somehow create a View, that gives me a result with the type's as columns? So right now I would get something like #profile type value 1 email [email protected] 1 name Sebastian Hoitz 1 website domain.tld But it would be nice to get a result like this: #profile email name website 1 [email protected] Sebastian Hoitz domain.tld The reason I do not want to create the table layout like this initially is, that there might always be things to add and I want to be able to have multiple attributes of the same type. So do you know if there is any possibility to convert this dynamically? If you need a better description please let me know. Thank you!

• Pulling data and printing it in an HTML table

  - by John

  Hello, From a MySQL table called "submission" containing the fields "loginid, submissionid, title, url, datesubmitted, displayurl", I would like to print an HTML table thats contains all "title" and corresponding "datesubmitted" where "loginid" equals "$profile." The code I am trying to use is below. It isn't working. Any ideas why it isn't working? Thanks in advance, John $profile = $_GET['profile']; $sqlStr = "SELECT loginid, submissionid, title, url, datesubmitted, displayurl FROM submission WHERE loginid = $profile ORDER BY datesubmitted DESC"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www.'.$row["url"].'">'.$row["title"].'</a></td>'; echo '</tr>'; echo '<tr>'; echo '<td class="sitename2">'.$row["datesubmitted"].'</a></td>'; echo '</tr>'; } echo "</table>";

• Dots and spaces in variable names from external sources are converted to underscores

  - by Brandon

  Trying a bit of AJAX, and I find that much of my data is littered with underscores! Documentation confirms that this is working as intended. Any way to pass my form information to PHP intact? I'm using CodeIgniter, so my pass looks like /controller/function/variable, receiving controller: controller{ function($v=0){#what once was hello world is now hello_world...} } I can't very well do an undo, data might contain an underscore. Thanks, Brandon

• javascript: why to "sign-prefix" a variable?

  - by harald

  hello, i'm currently looking at a little 3rd-party javascript library and i see a lot of "sign-prefixed" variables in it: function_call(+value); i know, that you can swap the sign, if you prefix a variable with '-', but why to prefix something with a '+' -- it doesn't do anything to the value, no? thanks in advance!

• Best way to enforce inter-table constraints inside database

  - by FerranB

  I looking for the best way to check for inter-table constraints an step forward of foreing keys. For instance, to check if a date child record value is between a range date on two parent rows columns. For instance: Parent table ID DATE_MIN DATE_MAX ----- ---------- ---------- 1 01/01/2009 01/03/2009 ... Child table PARENT_ID DATE ---------- ---------- 1 01/02/2009 1 01/12/2009 <--- HAVE TO FAIL! ... I see two approaches: Create materialized views on-commit as shown in this article (or other equivalent on other RDBMS). Use stored-procedures and triggers. Any other approach? Which is the best option? UPDATE: The motivation of this question is not about "putting the constraints on database or on application". I think this is a tired question and anyone does the way she loves. And, I'm sorry for detractors, I'm developing with constraints on database. From here, the question is "which is the best option to manage inter-table constraints on database?". I'm added "inside database" on the question title. UPDATE 2: Some one added the "oracle" tag. Of course materialized views are oracle-tools but I'm interested on any option regardless it's on oracle or others RDBMSs.
