  • 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

  • what are the recent dataStructure and algorithms that one should know?

    - by Shamik
    Recently I came across the SkipList data structure. It really helped me to solve one otherwise critical problem to be solved. I was struggling to solve the same problem with Balanced Binary tree but it became very complex as the tree needs to be always balanced and I wanted to know the existence of not only a particular value but values in certain range. SkipList helped me to solve that problem effectively. I am wondering what else data structures that I need to know? I know - Array, List, Stack, Queue, Linked List, hashtable, tree and its different forms like B-tree, Trie etc. Would like to know if you find some other data structure/concept very interesting to know yet effective enough to be used in a daily development cycle.

    Hi, guys, I'm coding a web page in Hibernate-JPA and Oracle. I need the following: I have two classes: Place and Home.

How Can I get Two ManyToOne relationship to same primary key with insert a true?.

  • RegEx expression to find a href links and add NoFollow to them

    - by Rodney
    I am trying to write a RegEx rule to find all a href HTML links on my webpage and add a 'rel="nofollow"' to them. However, I have a list of URLs that must be excluded (for exmaple, ANY (wildcards) internal link (eg. pokerdiy.com) - so that any internal link that has my domain name in is excluded from this. I want to be able to specify exact URLs in the exclude list too - for example - http://www.example.com/link.aspx) Here is what I have so far which is not working: (]+)(href="http://.*?(?!(pokerdiy))[^]+) If you need more background/info you can see the full thread and requirements here (skip the top part to get to the meat): http://www.snapsis.com/Support/tabid/601/aff/9/aft/13117/afv/topic/afpgj/1/Default.aspx#14737

  • Passing values across pages ASP.net

    - by GigaPr
    Hi i need to pass a long list of Ids from one page to another, i was thinking of using querystring but taking in consideration that the number of ids to be passed may reach 300 i think is not a good idea. an option from my understanding may be the use of session, this seems to me an optimal solution in my case but on the other hand I can certainly clear the session when the user performs a certain action and the list of ids is not longer needed, but if the user leaves the page without performing any action i want to clear the session, how can i do it? If multiple users are using the same functionality do i need the session's items to be confused or the session is for a single user? I am working in asp.net c# Thanks

  • Compare two object lists with LINQ on specific property

    - by Niklas
    I have these two lists (where the Value in a SelectListItem is a bookingid): List<SelectListItem> selectedbookings; List<Booking> availableBookings; I need to find the ids from selectedBookings that are not in availableBookings. The LINQ join below will only get me the bookingids that are in availableBookings, and I'm not sure how to do it the other way around. != won't work since I'm comparing strings. results = ( from s in selectedbookings join a in availableBookings on s.bookingID.ToString() equals a.Value select s);

  • Simpler array declaration syntax in c++

    - by AareP
    In the spirit of Go-language, where simpler syntax is considered pretty important, here's a proposal for simpler array declaration in c++: int value; int_1 list; int_2 table; int_3 cube; RECT rect; RECT_1 rects; Using typedefs this can expand to: int value; vector<int> list; vector<int> table; vector<int> cube; RECT rect; vector<RECT> rects; Would you use it, or is there such a thing as too simple syntax?

  • How to do query auto-completion/suggestions in Lucene?

    - by Mat Mannion
    I'm looking for a way to do query auto-completion/suggestions in Lucene. I've Googled around a bit and played around a bit, but all of the examples I've seen seem to be setting up filters in Solr. We don't use Solr and aren't planning to move to using Solr in the near future, and Solr is obviously just wrapping around Lucene anyway, so I imagine there must be a way to do it! I've looked into using EdgeNGramFilter, and I realise that I'd have to run the filter on the index fields and get the tokens out and then compare them against the inputted Query... I'm just struggling to make the connection between the two into a bit of code, so help is much appreciated! To be clear on what I'm looking for (I realised I wasn't being overly clear, sorry) - I'm looking for a solution where when searching for a term, it'd return a list of suggested queries. When typing 'inter' into the search field, it'll come back with a list of suggested queries, such as 'internet', 'international', etc.

  • Jet Database (ms access) ExecuteNonQuery - Can I make it faster?

    - by bluebill
    Hi all, I have this generic routine that I wrote that takes a list of sql strings and executes them against the database. Is there any way I can make this work faster? Typically it'll see maybe 200 inserts or deletes or updates at a time. Sometimes there is a mixture of updates, inserts and deletes. Would it be a good idea to separate the queries by type (i.e. group inserts together, then updates and then deletes)? I am running this against an ms access database and using vb.net 2005. Public Function ExecuteNonQuery(ByVal sql As List(Of String), ByVal dbConnection as String) As Integer If sql Is Nothing OrElse sql.Count = 0 Then Return 0 Dim recordCount As Integer = 0 Using connection As New OleDb.OleDbConnection(dbConnection) connection.Open() Dim transaction As OleDb.OleDbTransaction = connection.BeginTransaction() 'Using cmd As New OleDb.OleDbCommand() Using cmd As OleDb.OleDbCommand = connection.CreateCommand cmd.Connection = connection cmd.Transaction = transaction For Each s As String In sql If Not String.IsNullOrEmpty(s) Then cmd.CommandText = s recordCount += cmd.ExecuteNonQuery() End If Next transaction.Commit() End Using End Using Return recordCount End Function

  • EXCEL - Locking a Cell from User input whilst allowing a Linked combobox?

    - by Christopher Leach
    I have a Protected Worksheet which is a checklist with a series of checkpoints. Each row has Item and Description cells that are locked. Each row has several columns with its contents to be set by a ComboBox and a text input column. Both i have left unlocked. I have Locked the the Item and Description columns and left only the 'Select Unlocked Cells' checked via Sheet Protection. I have one ComboBox on the worksheet that moves around and adjusts its LinkedCell and its Content list using the worksheets SelectionChanged event. When the user selects a cell to bring up the drop down list, the user is able to type into the cell and the Drop Down Box disappears. What is the best way to keep the cell unlocked so it can be selectable(as 'Select Locked Cells" is unchecked) however stop the user from being able to type in the cell and to allow the cells contents to become modifiable only via the ComboBox?

  • Why is this statement treated as a string instead of its result?

    - by reve_etrange
    I am trying to perform some composition-based filtering on a large collection of strings (protein sequences). I wrote a group of three subroutines in order to take care of it, but I'm running into trouble in two ways - one minor, one major. The minor trouble is that when I use List::MoreUtils 'pairwise' I get warnings about using $a and $b only once and them being uninitialized. But I believe I'm calling this method properly (based on CPAN's entry for it and some examples from the web). The major trouble is an error "Can't use string ("17/32") as HASH ref while "strict refs" in use..." It seems like this can only happen if the foreach loop in &comp is giving the hash values as a string instead of evaluating the division operation. I'm sure I've made a rookie mistake, but can't find the answer on the web. The first time I even looked at perl code was last Wednesday... use List::Util; use List::MoreUtils; my @alphabet = ( 'A', 'R', 'N', 'D', 'C', 'Q', 'E', 'G', 'H', 'I', 'L', 'K', 'M', 'F', 'P', 'S', 'T', 'W', 'Y', 'V' ); my $gapchr = '-'; # Takes a sequence and returns letter = occurrence count pairs as hash. sub getcounts { my %counts = (); foreach my $chr (@alphabet) { $counts{$chr} = ( $[0] =~ tr/$chr/$chr/ ); } $counts{'gap'} = ( $[0] =~ tr/$gapchr/$gapchr/ ); return %counts; } # Takes a sequence and returns letter = fractional composition pairs as a hash. sub comp { my %comp = getcounts( $[0] ); foreach my $chr (@alphabet) { $comp{$chr} = $comp{$chr} / ( length( $[0] ) - $comp{'gap'} ); } return %comp; } # Takes two sequences and returns a measure of the composition difference between them, as a scalar. # Originally all on one line but it was unreadable. sub dcomp { my @dcomp = pairwise { $a - $b } @{ values( %{ comp( $[0] ) } ) }, @{ values( %{ comp( $[1] ) } ) }; @dcomp = apply { $_ ** 2 } @dcomp; my $dcomp = sqrt( sum( 0, @dcomp ) ) / 20; return $dcomp; } Much appreciation for any answers or advice!

  • C# ToDictionary can valueSelector give null?

    - by Trimack
    Hi, I want to make a dictionary out of list in a way, that the list becomes keys and values would be empty. I have following code Dictionary<XmlTest, int?> testBattery = new XmlTests().GetRandomTestBattery(id). ToDictionary(k => k, v => null); But I am getting the error "Cannot convert lambda expression to type System.Collections.Generic.IEqualityComparer' because it is not a delegate type" Any ideas how could I fix it? (I know I could iterate through and fill the dict one element at a time, but I simply want to use something more elegant)

  • Using reshape + cast to aggregate over multiple columns

    - by DamonJW
    In R, I have a data frame with columns for Seat (factor), Party (factor) and Votes (numeric). I want to create a summary data frame with columns for Seat, Winning party, and Vote share. For example, from the data frame df <- data.frame(party=rep(c('Lab','C','LD'),times=4), votes=c(1,12,2,11,3,10,4,9,5,8,6,15), seat=rep(c('A','B','C','D'),each=3)) I want to get the output seat winner voteshare 1 A C 0.8000000 2 B Lab 0.4583333 3 C C 0.5000000 4 D LD 0.5172414 I can figure out how to achieve this. But I'm sure there must be a better way, probably a cunning one-liner using Hadley Wickham's reshape package. Any suggestions? For what it's worth, my solution uses a function from my package djwutils_2.10.zip and is invoked as follows. But there are all sorts of special cases it doesn't deal with, so I'd rather rely on someone else's code. aggregateList(df, by=list(seat=seat), FUN=list(winner=function(x) x$party[which.max(x$votes)], voteshare=function(x) max(x$votes)/sum(x$votes)))

  • AIR SQLite IN expression not working

    - by goseta
    Hi, I'm having a problem with an expression in my sql statement in SQLite for Adobe AIR basically I have this sql = "UPDATE uniforms SET status=@status WHERE customerId IN(19,20)"; updateStmt.parameters["@status"] = args[1]; updateStmt.execute(); if I run the above code it works, updating the status when the id are 19 and 20 but if I pass the ids list as a parameter like this sql = "UPDATE uniforms SET status=@status WHERE customerId IN(@ids)"; updateStmt.parameters["@status"] = args[1]; updateStmt.parameters["@ids"] = "19,20"; updateStmt.execute(); it gives me and error, saying could not convert text value to numeric value, which make sense because I'm passing and string but the IN expression should convert it accordingly, like it does when I pass directly the list values, why is not working the other way, thanks for any help!

  • How to show empty view when ListView is empty?

    Here is my layout. For some reason the empty view (TextView in this case) always appears, even when the List is not empty.

  • improve my jquery validation plugin code

    - by Jared
    Hi All Just hoping soemone can help me to write better code than I can come up with on my own. I am using the jquery validation plugin. I have some fields that are mandatory ONLY if certain options are chosen. The below code works fine. But the thing is, is that that my list of 'OR's is much longer than I've put here. and it needs to be applied not just to 'directorsName' but a whole long list of inputs, selects etc. My question is.. how can I wrap up the code contained inside the RETURN? (so I dont have to keep repeating my 'OR's. I'm guessign I need a function but I'm unsure of the syntax) $("#myForm").validate({ rules: { directorsName : { required: function(element) { return ( $('#account_for').val() == "Joint" || $('#directors_number').val() == "2" || $('#directors_number').val() == "3" ); } } } }); Thanks in advance

  • [Seamless Handover of WiFi] Can we program to automatically join the WiFi with the most strongest si

    - by Dobby
    Hi all, I am making a iphone program, I wish that: it can sense and display the current signals of wifi, with strength, - as I checked, this cannot be done by official SDK, but there were some private library that can handle. 2. i wish it can always automatically join the best wifi with the most highest strength ( assume that all wifi APs have no password, and all are not remembered into the used-list inside iphone), which is something like "seamless handover"... I just guess that, there should be some APIs to let the system join one designated wifi signal from the list, and wish someone could help me. I would like to appreciate a lot : ) Thanks a lot!

  • RMI client tracking

    - by 0000
    I'm building a Client / Server app that has some very specific needs. There are 2 kinds of servers: the first kind provide most of the remote procedures and clients connect to these directly, while the second kind is a single server that should keep track of what users are active (clients) and how many servers of the first kind are active when a method is called. The main thing is that the monitor should ONLY connect to the servers and not the clients directly. My first idea was to implement a simple login/logout rmi method when a client connects/ disconnects and keep track of those in a list but the main problem is when a client or server end abnormally. For example, if a client goes offline abruptly the server should somehow be notified and update the list accordingly, while if a server goes out all of the clients connected to it should be marked as not active in the control server. Any ideas of how to implement this functionality would be appreciated.

  • How to store array of NSManagedObjects in an NSManagedObject

    - by David Tay
    I am loading my app with a property list of data from a web site. This property list file contains an NSArray of NSDictionaries which itself contains an NSArray of NSDictionaries. Basically, I'm trying to load a tableView of restaurant menu categories each of which contains menu items. My property list file is fine. I am able to load the file and loop through the nodes structure creating NSEntityDescriptions and am able to save to Core Data. Everything works fine and expectedly except that in my menu category managed object, I have an NSArray of menu items for that category. Later on, when I fetch the categories, the pointers to the menu items in a category is lost and I get all the menu items. Am I suppose to be using predicates or does Core Data keep track of my object graph for me? Can anyone look at how I am loading Core Data and point out the flaw in my logic? I'm pretty good with either SQL and OOP by themselves, but am a little bewildered by ORM. I thought that I should just be able to use aggregation in my managed objects and that the framework would keep track of the pointers for me, but apparently not. NSError *error; NSURL *url = [NSURL URLWithString:@"http://foo.com"]; NSArray *categories = [[NSArray alloc] initWithContentsOfURL:url]; NSMutableArray *menuCategories = [[NSMutableArray alloc] init]; for (int i=0; i<[categories count]; i++){ MenuCategory *menuCategory = [NSEntityDescription insertNewObjectForEntityForName:@"MenuCategory" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *category = [categories objectAtIndex:i]; menuCategory.name = [category objectForKey:@"name"]; NSArray *items = [category objectForKey:@"items"]; NSMutableArray *menuItems = [[NSMutableArray alloc] init]; for (int j=0; j<[items count]; j++){ MenuItem *menuItem = [NSEntityDescription insertNewObjectForEntityForName:@"MenuItem" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *item = [items objectAtIndex:j]; menuItem.name = [item objectForKey:@"name"]; menuItem.price = [item objectForKey:@"price"]; menuItem.image = [item objectForKey:@"image"]; menuItem.details = [item objectForKey:@"details"]; [menuItems addObject:menuItem]; } [menuCategory setValue:menuItems forKey:@"menuItems"]; [menuCategories addObject:menuCategory]; [menuItems release]; } if (![[self managedObjectContext] save:&error]) { NSLog(@"An error occurred: %@", [error localizedDescription]); }

  • In which controller do you put the CRUD for the child part of a relationship?

    - by uriDium
    I am using ASP.Net MVC but this probably applies to all MVC patterns in general. My problem, for example I have companies and in each company I have a list of contacts. When I have selected a company I can see its details and a list of the contacts for that company. When I want to add a new contact for that company, should the implementation of that action go into the company controller as an "AddContact" action or should it go into the contact controller into a "New" action and we pass the Company ID in the URL? What is the usual way of dealing with this sort of thing in ASP.Net MVC? Is there a better stategy?
