• need more complex index !

  - by silversky

  I'm sorry if it's not an appropriate question for this site, and if it's necesary I'll close this question. But maybe someone could give me an ideea: I'm trying to find a more complex index to make an hierarchy. For example: 5 votes from 6 = 83% AND 500 votes from 600 = 83%; 10 votes from 600 = 1.66% If I make a hierarchy with the %, first two will be on the same place, but I think that 83% from 600 it's more valuable than the first one. I could compare 5, 10, 500, but again it's not fair because the third case (10 votes) will be in front of the first case (5 votes), wich it's not fair beacuse the third case has only 1.66% Maybe someone could give me an ideea how to give more weight for the second case but in the same time let the let the new entries have a fair chance.

• Complex select query question for hardcore SQL designers

  - by eugeneK

  Very complex query been trying to construct it for few days with more real success. I'm using SQL-SERVER 2005 Standard What i need is : 5 CampaignVariants from Campaigns whereas 2 are with the largest PPU number set and 3 are random. Next condition is that CampaignDailyBudget and CampaignTotalBudget are below what is set in Campaign ( calculation is number of clicks in Visitors table connected to Campaigns via CampaignVariants on which users click) Next condition CampaignLanguage, CampaignCategory, CampaignRegion and CampaignCountry must be the ones i send to this select with (languageID,categoryID,regionID and countryID). Next condition is that IP address i send to this select statement won't be in IPs list for current Campaign ( i delete inactive for 24 hours IPs ). In other words it gets 5 CampaignVariants for user that enters the site, when i take from user PublisherRegionUID,IP,Language,Country and Region view diagram

• complex web forms and javascript

  - by Casey

  I need to create a few data heavy complicated forms. Currently, the information is being entered into a spread sheet, but the users will need to enter the information into the online form where it will be saved to a database. The problem is that the business users currently using the spread sheet aren't going to want to use the online application if it isn't as easy as entering the information into the spread sheet. This is further complicated in that the information they are entering into the spread sheet is represented by three different DB tables where one "object" is composed of two of the others. I would prefer to not have them have to go through multiple forms. Some of what I have been thinking is: Use of auto complete where possible Hiding/removing form fields dynamically possible wizard style page flow?? I've been googling for other data heavy web forms but can't seem to really find any good examples. I am familiar with jQuery and prototypejs and have also tried googling for frameworks designed for data heavy applications but didn't come up with anything. Any thoughts? Thanks.

• How does the iPhone SDK Core Data system store date types to sqlite?

  - by Andrew Arrow

  I used core data to do this: NSManagedObjectContext *m = [self managedObjectContext]; Foo *f = (Foo *)[NSEntityDescription insertNewObjectForEntityForName:@"Foo" inManagedObjectContext:m]; f.created_at = [NSDate date]; [m insertObject:f]; NSError *error; [m save:&error]; Where the created_at field is defined as type "Date" in the xcdatamodel. When I export the sql from the sqlite database it created, created_at is defined as type "timestamp" and the values look like: 290902422.72624 Nine digits before the . and then some fraction. What is this format? It's not epoch time and it's not julianday format. Epoch would be: 1269280338.81213 julianday would be: 2455278.236746875 (notice only 7 digits before the . not 9 like I have) How can I convert a number like 290902422.72624 to epoch time? Thanks!

• Hashing the state of a complex object in .NET

  - by Jan

  Some background information: I am working on a C#/WPF application, which basically is about creating, editing, saving and loading some data model. The data model contains of a hierarchy of various objects. There is a "root" object of class A, which has a list of objects of class B, which each has a list of objects of class C, etc. Around 30 classes involved in total. Now my problem is that I want to prompt the user with the usual "you have unsaved changes, save?" dialog, if he tries to exit the program. But how do I know if the data in current loaded model is actually changed? There is of course ways to solve this, like e.g. reloading the model from file and compare against the one in memory value by value or make every UI control set a flag indicating the model has been changed. Now instead, I want to create a hash value based on the model state on load and generate a new value when the user tries to exit, and compare those two. Now the question: So inspired of that, I was wondering if there exist some way to generate a hash value from the (value)state of some arbitrary complex object? Preferably in a generic way, e.g. no need to apply attributes to each involved class/field. One idea could be to use some of .NET's serialization functionality (assuming it will work out-of-the-box in this case) and apply a hash function to the content of the resulting file. However, I guess there exist some more suitable approach. Thanks in advance.

• ActionLink sending a model of a complex type

  - by Xenph Yan

  I'm trying to paginate the results of a "advanced search", I have a complex model that represents the search options; int ZipCode int MinAge int MaxAge Availability bool Monday bool Tuesday ... bool Friday Requirements bool FirstAid bool DriversLicense I'm using; <%: Html.ActionLink("Next »", "Save", "Notification", Model.options)%> Which correctly sends all the data at the first level, but anything that is a sub-object (Availability or requirements) isn't expanded in the URL, all I get is the class name and so I lose most of the search options when I click the link to change to a different page. Any thoughts?

• Django complex queries

  - by Josh K

  I need to craft a filter for an object that checks date ranges. Right now I'm performing a very inefficient loop which checks all the objects. I would like to simplify this to a database call. The logic is you have a start and an end date objects. I need to check if the start OR the end is within the range of an appointment. if (start >= appointment.start && start < appointment.end) || (end > appointment.start && end <= appointment.end) I could do this in SQL, but I'm not as familiar with the Django model structure for more complex queries.

• NSArray vs. SQLite for Complex Queries on iPhone

  - by GingerBreadMane

  Developing for iPhone, I have a collection of points that I need to make complex queries on. For example: "How many points have a y-coordinate of 10" and "Return all points with an X-coordinate between 3 and 5 and a y-coordinate of 7". Currently, I am just cycling through each element of an NSArray and checking to see if each element matches my query. It's a pain to write the queries though. SQLite would be much nicer. I'm not sure which would be more efficient though since a SQLite database resides on disk and not in memory (to my understanding). Would SQLite be as efficient or more efficient here? Or is there a better way to do it other than these methods that I haven't thought of? I would need to perform the multiple queries with multiple sets of points thousands of times, so the best performance is important.

• SQL Syntax for Complex Scenario (Deals)

  - by Yisman

  hello everyone i have a complex query to be written but cannot figure it out here are my tables Sales --one row for each sale made in the system SaleProducts --one row for each line in the invoice (similar to OrderDetails in NW) Deals --a list of possible deals/offers that a sale may be entitled to DealProducts --a list of quantities of products that must be purchased in order to get a deal now im trying to make a query which will tell me for each sale which deals he may get the relevant fields are: Sales: SaleID (PK) SaleProducts: SaleID (FK), ProductID (FK) Deals: DealID (PK) DealProducts: DealID(FK), ProductID(FK), Mandatories (int) for required qty i believe that i should be able to use some sort of cross join or outer join, but it aint working here is one sample (of about 30 things i tried) SELECT DealProducts.DealID, DealProducts.ProductID, DealProducts.Mandatories, viwSaleProductCount.SaleID, viwSaleProductCount.ProductCount FROM DealProducts LEFT OUTER JOIN viwSaleProductCount ON DealProducts.ProductID = viwSaleProductCount.ProductID GROUP BY DealProducts.DealID, DealProducts.ProductID, DealProducts.Mandatories, viwSaleProductCount.SaleID, viwSaleProductCount.ProductCount the problem is that it doesnt show any product deals that r not fullfiled (probably because of the productid join). i need that also sales that dont have the requiremnets show up, then i can filter out any saleid that exists in this query "where AmountBought thank you for your help

• Searching for a complex and well-designed PHP OOP application to learn from

  - by Raveren

  Basically, I am diving ever deeper into complex programming practices. I've almost no friends that are experienced (or more experienced than me) programmers to learn from, so I am looking for the next best thing - learning from the work of strangers. Can anyone recommend a real world finished and working application written well and OOP-centered. I'd like to take and analyze its source. Bonus if it's based on Zend Framework. What I am interested most in is objects that unlike desktop applications, have only one real operation done to them (or to their representation in DB or session) during their lifetime (or pageload), like user-logIn(). I'm interested in optimal and reusable design patterns and their real life implementations.

• Would you store binary data in database or in file system?

  - by paul

  This is a question which has been asked before (large-text-and-images-in-sql) but mainly for data which will be changed. In my case the data will be stored and never changed. Just seems sensible to keep everything together. Are there any reasons why I should not store static binary data in a database? Assuming it is a sensible thing to do, are there any advantages to storing such data in separate tables? (You might begin to realise now that I'm not a DB expert...) Clarify: There will probably be no more than 10-20 users but these will be in the US and in the UK. The binary data will have to be transfered in any case.

• Entering Complex Data into Access

  - by DataMakesMeCrazy

  Fairly new to Access and trying to do something that seems simple, but may be very complex. I want to create a database of projects, each project has several phases (ie proposal, marketing, etc) and that will allow for multiple employees to work on a single project. Ie Bob and John are working on project number 102. From here, i would like to enter the forecasted start and end dates for each phase of the project, and enter the forecasted number our hours each employee will be allowed to work on that phase of that project ie. Project - Employee - Phase - Start - End - (list weeks) 102 - Bob - Marketing - 12-May-10 - 21-May-10 - 3 - 5 (3 hours first week, 5 hours the second) and so on Basically would all this data be on one table, or several? And can access dynamically show the weeks between the start and end date so that i can input the hours? I feel this database will become severely complicated :S Thanks, J

• Complex nib is slow to load

  - by Dan Ray

  I'm looking for advice about a nib that's very slow to load. It's big and complex, with lots of subviews and doodads. When I fire my UINavController to push it, it's noticeably laggy (maybe almost a second) on my 3G. It sits there with the table cell selected and nothing else happening for long enough to make you wonder if it's broken. I wonder about pre-loading it in another thread while the user is on the previous view. I could probably fire the selector in the background with a delay in the previous view's viewDidAppear, and then keep it in a property until push time comes. Thoughts?

• How to separate model and view with Core Data?

  - by andrewebling

  I have a subclass of UIView which draws itself based on data held in a corresponding model class, which is a subclass of NSManagedObject. The problem is, some fields in the data model (e.g. the position of the view) are already held in the view (i.e. the frame property in this case). I then have a data duplication/synchronization problem to solve. To complicate matters further, the view needs to update in response to changes made to the data model and the data model needs to be updated in responses made to the view (e.g. the user dragging it to a new location). What's the best way to solve this? Using KVO and references in both directions? Or is there a better approach?

• Dynamically generate Triangle Lists for a Complex 3D Mesh

  - by Vulcan Eager

  In my application, I have the shape and dimensions of a complex 3D solid (say a Cylinder Block) taken from user input. I need to construct vertex and index buffers for it. Since the dimensions are taken from user input, I cannot user Blender or 3D Max to manually create my model. What is the textbook method to dynamically generate such a mesh? Edit: I am looking for something that will generate the triangles given the vertices, edges and holes. Something like TetGen. As for TetGen itself, I have no way of excluding the triangles which fall on the interior of the solid/mesh.

• Access: Expression too complex to be evaluated

  - by user2502964

  I'm trying to sort out values from a database by the weekending date. The script I'm using functions on 6 of my 7 databases (they are all constructed identically). The 7th database doesn't function. I get the expression too complex error. any help figuring out why?? Here is my code: SELECT UPC_Test.Type, UPC_Test.[Model No], UPC_Test.[Model Desc], UPC_Test.[Serial No], Format(DateValue([UPC_Test].[Test Date]+7-Weekday([UPC_Test].[Test Date],0)),"m/d/yyyy") AS [Test Date], UPC_Test.Parameter, UPC_Test.[Failure Symptom], UPC_Test.[Repair Action], UPC_Test.[Factory Select], UPC_Test.[Test Station] FROM UPC_Test GROUP BY UPC_Test.Type, UPC_Test.[Model No], UPC_Test.[Model Desc], UPC_Test.[Serial No], Format(DateValue([UPC_Test].[Test Date]+7-Weekday([UPC_Test].[Test Date],0)),"m/d/yyyy"), UPC_Test.Parameter, UPC_Test.[Failure Symptom], UPC_Test.[Repair Action], UPC_Test.[Factory Select], UPC_Test.[Test Station] HAVING (((UPC_Test.Type)="Production") AND ((Format(DateValue([UPC_Test].[Test Date]+7-Weekday([UPC_Test].[Test Date],0)),"m/d/yyyy"))=[Enter]) AND ((UPC_Test.[Failure Symptom])<>"") AND ((UPC_Test.[Repair Action])<>"") AND ((UPC_Test.[Test Station])="UPC RF Test")) ORDER BY Format(DateValue([UPC_Test].[Test Date]+7-Weekday([UPC_Test].[Test Date],0)),"m/d/yyyy");

• Complex class using PHP soapserver mapclass

  - by user559343

  Hi all, I need to create a server for processing SOAP requests. I have the wsdl and xml specifications, but I have a doubt: the xml elements are pretty complex, they are not simple type, but they have parent/child relationships (e.g. I have a Book class with an author subclass). How can I map this to PHP classes? In this example, should I create an author class i.e.: class Author { public $name; public $surname; } and then class Book { public $author; } will $author be a class of type Author? Or a typed array? Any help will be appreciated Thanks and happy new year!

• How to modify complex argument strings in Perl

  - by mmccoo

  I have a cmdline that I'm trying to modify to remove some of the arguments. What makes this complex is that I can have nested arguments. Say that I have this: $cmdline = "-a -xyz -a- -b -xyz -b- -a -xyz -a-" I have three different -xyz flags that are to be interpreted in two different contexts. One is the -a context and the other is the -b context. I want to remove the "a" -xyz's but leave the ones in the "b" -xyz. How can I most effectively do this in Perl?

• Need help with some complex SQL query

  - by Psyche

  Hello guys, I need some help with a complex SQL query. Here's my setup: there are two tables, one with authors, and another with books. The books table contains a field named "author" which holds author's id. If a book has more than one author, then the "author" field will contain all the authors ids separated by ";" (something like 2;34;234). On the website I have to list all the books written by an author. If there's only one author, its simple, but how can I get those books where the author I'm interested in is the second or third author? Many thanks.

• Need an efficient algorithm solve this kind of complex structure

  - by Rizvan

  Problem Statement is : Given 2 Dimensional array, print output for example If 4 rows and 6 columns, output would be: 1 2 3 4 5 6 16 17 18 19 20 7 15 24 23 22 21 8 14 13 12 11 10 9 I tried it is looking like square within square but when I attempted this problem, I put so many while and if loops but didn't got exact answer. If row and columns increases how to handle it? This is not homework. I was learning solving complex structure so I need to understand it by some guidance.

• Complex SQL queries (DELETE)?

  - by Joe

  Hello all, I'm working with three tables, and for simplicity's sake let's call them table A, B, and C. Both tables A and B have a column called id, as well as one other column, Aattribute and Battribute, respectively. Column c also has an id column, and two other columns which hold values for A.id and B.id. Now, in my code, I have easy access to values for both Aattribute and Battribute, and want to delete the row at C, so effectively I want to do something like this: DELETE FROM C WHERE aid=(SELECT id FROM A WHERE Aattribute='myvalue') AND bid=(SELECT id FROM B WHERE Battribute='myothervalue') But this obviously doesn't work. Is there any way to make a single complex query, or do I have to run three queries, where I first get the value of A.id using a SELECT with 'myvalue', then the same for B.id, then use those in the final query? [Edit: it's not letting me comment, so in response to the first comment on this: I tried the above query and it did not work, I figured it just wasn't syntactically correct. Using MS Access, for what it's worth. ]

• Difference between adding MIME types in IIS via Websites vs Local Computer?

  What is the difference between adding MIME types in these 2 different situations? When in IIS 6 manager... Right click on the computer name (local computer) properties mime types Right click on the "Web sites" folder properties http headers mime types I'm guessing that perhaps option 1 adds MIME types for FTP also? However if that were true i'd expect to be able to add MIME types specifically in the properties of FTP (and not just websites). thanks for your help.
