  • Hibernate inserting into join table

    - by Karl
    I got several entities. Two of them got a many-to-many relation. When I do a bigger operation on these entities it fails with this exception: org.hibernate.exception.ConstraintViolationException: could not insert collection rows: I execute the operation i a @Transactional context. I don't do any explicit flushing i my daos. The flush is triggered by a query. In the queue are 15 elements (all of the same structure). one of them always fails (but it's always a different one (I checked) and always at a different position). Does anybody have a hint for me for what I might do wrong? My Mapping: @ManyToMany(targetEntity = CategoryImpl.class) protected Set<Category> categories = new HashSet<Category>();

  • Stop SQL returning the same result twice in a JOIN

    - by nbs189
    I have joined together several tables to get data i want but since I am new to SQL i can't figure out how to stop data being returned more than once. her's the SQL statement; SELECT T.url, T.ID, S.status, S.ID, E.action, E.ID, E.timestamp FROM tracks T, status S, events E WHERE S.ID AND T.ID = E.ID ORDER BY E.timestamp DESC The data that is returned is something like this; +----------------------------------------------------------------+ | URL | ID | Status | ID | action | ID | timestamp | +----------------------------------------------------------------+ | T.1 | 4 | hello | 4 | has uploaded a track | 4 | time | | T.2 | 3 | bye | 3 | has some news | 3 | time | | t.1 | 4 | more | 4 | has some news | 4 | time | +----------------------------------------------------------------+ That's a very basic example but does outline what happens. If you look at the third row the URL is repeated when there is a different status. This is what I want to happen; +-------------------------------------------------------+ | URL or Status | ID | action | timestamp | +-------------------------------------------------------+ | T.1 | 4 | has uploaded a track | time | | hello | 3 | has some news | time | | bye | 4 | has some news | time | +-------------------------------------------------------+ Please notice that the the url (in this case the mock one is T.1) is shown when the action is has uploaded a track. This is very important. The action in the events table is inserted on trigger of a status or track insert. If a new track is inserted the action is 'has uploaded a track' and you guess what it is for a status. The ID and timestamp is also inserted into the events table at this point. Note: There are more tables that go into the query, 3 more in fact, but I have left them out for simplicity.

  • Adding fields until screen is full

    - by Eric
    For the sake of this question, let us suppose that I want a row of buttons. I want to put as many buttons in that row as I can fit on the screen, but no more. In other words, as long as a prospective button will not be cut off or have its text shortened, add it. It seems that I should be able to do something like: HorizontalFieldManager hfm = new HorizontalFieldManager(); int remainingWidth = Display.getWidth(); int i =0; while(true) { ButtonField bf = new ButtonField("B " + i); remainingWidth -= bf.getWidth(); if(remainingWidth<0) break; hfm.add(bf); i++; } add(hfm); But this doesn't work. bf.getWidth() is always 0. I suspect that this is because the button has not yet been laid out when I query for the width. So, perhaps I could just make sure the buttons are always the same size. But this won't work for a few reasons: Different BB platforms have different looks for buttons and text that will fit on a button on a Curve won't fit on a button on a Storm. 3rd party themes may change the look of buttons, so I can't even count on buttons being a certain size on a certain platform. Is there no way for me to actually check the remaining space before adding a button? It feels like a fairly useful feature; am I just missing something?

  • StructureMap Configuration Per Thread/Request for the Full Dependency Chain

    - by Phil Sandler
    I've been using Structuremap for a few months now, and it has worked great on some smaller (green field) projects. Most of the configurations I have had to set up involve a single implementation per interface. In the cases where I needed to choose a specific implementation at runtime, I created a factory class that used ObjectFactory.GetNamedInstance<(). In the smaller projects, there were few enough of these cases where I was comfortable with the references to ObjectFactory. My understanding is that you want to limit these references as much as possible, and ideally only reference the ObjectFactory once. I am working to refactor a larger codebase to use IOC/StructureMap, and am finding that I may need many of these factory classes with ObjectFactory references to get what I need. Essentially, I am creating a "root service" with the ObjectFactory, so that everything in the dependency chain is managed by the container. The root service is created by name (i.e. "BuildCar", "BuildTruck"), and the services needed deeper in the dependency chain could also be constructed using the same name--so the "IAttachWheels" service could vary based on whether a car or truck is being built. Since the class that depends on IAttachWheels is the same in both configurations, I don't think I can use ConstructedBy in the registry to choose the implementation. Also, to be clear, the IAttachWheels implementations need to be managed by the container as well, because the dependency chain runs fairly deep. I looked briefly at Profiles as an option, but read (here on StackOverflow) that changing profiles essentially changes implementations for all threads. Is there a feature that is similar to profiles that is thread/request specific? Is the factory class that references ObjectFactory approach the right way to go? Any thoughts would be appreciated.

  • Grails many to many using a third 'join' class

    - by andy mccullough
    I read that a m:m relationship often means there is a third class that isn't yet required. So I have m:m on User and Project, and I created a third domain class, ProjectMembership The three domains are as follows (minimized for illustration purposes): User class User { String name static hasMany = [projectMemberships : ProjectMembership] } Project Membership class ProjectMembership { static constraints = { } static belongsTo = [user:User, project:Project] } Project: class Project { String name static hasMany = [projectMemberships : ProjectMembership] static constraints = { } } If I have the ID of the user, how can I get a list of Project objects that they are assigned to?

  • Full and Partial Matching of Sets

    - by jeffrey
    I have several sets of the same type [Y, M, D] and am trying to write a function to search these sets and return an array of the available sets that fit my parameters. ReturnedSets = return_matches(Y,M,D); I want the three parameters of the function return_matches to be optional. Which means any combination of values can be used to return the sets. For example, one could write - return_matches(13,null,2); - and the function would look for all sets that contain [13, anyValue, 2]; I'm writing this in PHP, to allow users to manage dated files on my website, but I'd like to be able to use this function again for other uses. Thanks! edit: (This, or variations of this, is all I can come up with so far... There is something extra that I don't understand, because this function ends up / would not work to return sets that contain y and d, but leaving m arbitrary. if(y == s[0]){ if(m == s[1]){ if(d == s[2]){ print "day match"; } } else {print "month match";} } else {print "year match";} } else {print "no match";}

  • creating a full html file out of webloc in a batch mode

    - by Wordpress Newbie
    Hi, I've got over 400 bookmarks saved as .webloc files. I'd like to move them to the iPhone's goodReader app. goodReader cannot open webloc files. It can sork with pdf, html but not webloc. Do you know of a way or a program that would take a folder as its input, and convert every single .webloc file in it into a PDF version or a html version - so I can grab the converted files and move them onto iPhone. Thank you

  • MySQL Rating system (calculating average from two tables).

    - by MussuR
    I have two tables, videos and videos_ratings. The videos table has an int videoid field (and many others but those fields are not important I think) and many records. The videos_ratings table has 3 int fields: videoid, rating, rated_by which has many records (multiple records for each fields from the videos table) but not for all records from the videos table. Currently I have the following mysql query: SELECT `videos`.*, avg(`videos_ratings`.`vote`) FROM `videos`, `videos_ratings` WHERE `videos_ratings`.`videoid` = `videos`.`videoid` GROUP BY `videos_ratings`.`videoid` ORDER BY RAND() LIMIT 0, 12 It selects all the records from table videos that have a rating in table video_ratings and calculates the average correctly. But what I need is to select all records from the videos table, no matter if there is a rating for that record or not. And if there aren't any records in the videos_ratings table for that particular videos record, the average function should show 0. Hope someone could understand what I want... :) Thanks!

  • Advanced text search in actionscript-return ALL nouns,adjectives and verbs..

    - by eco_bach
    Hi I know that as3 has some powerful new text search capabilities, especially when combined with regex. I don't even know if this is possible, but I would like to somehow, search any block of text, and return all nouns, adjectives and verbs. What would be the best(most efficent) way to do this? Is regex an option? or would I have to load in some sort of open sourced dictionary 9as used in spellcheckers) to compare with or?? After, I've pulled all the nouns, adjectives and verbs, I need to count and prioritize by their frequency. Any suggestions welcome...

  • SQL Query, return value from table with no join

    - by jdenomme19
    I'm hoping for an idea on the best way to approach what I'm trying to do. I have a table with a list of transactions. Each transactions has a PostDate in DateTime format. I have another table holding the fiscal period values. This table has the following columns; FiscalYear, FiscalMonth, StartDate, EndDate. I'm trying to write a query that will return all values from my transactions table, along with the FiscalYear and FiscalMonth of the PostDate. So I guess I'm just trying to return the FiscalYear and FiscalMonth values when the PostDate falls between the StartDate and EndDate. I've tried using a Subbuery, but I have little experience with them and kept returning an error message that the subquery was returning more than 1 value. Help would be appreciated SELECT Transactions.PostDate, Transactions.TranKey, Transactions.CustKey, (SELECT FiscalPeriod.FiscPer FROM FiscalPeriod WHERE (Transactions.PostDate > CONVERT(Datetime, FiscalPeriod.StartDate, 102)) AND (Transactions.PostDate < CONVERT(DATETIME, FiscalPeriod.EndDate, 102))) AS FisPer FROM Transactions

  • SQL: joining multiples tables into one.

    - by Graveen
    I have 4 tables. r1, r2, r3 and r4. The table columns are the following: rId | rName I want to have, in fine, an unique table - let's call it R. Obviously, R will have the following structure: rTableName | rId | rName I'm looking for a solution, and the more natural for me is to: add a single column to all rX insert this column the table name i'm processing generate SQLs and concatenate them all Although I see exactly how to perform 1 and 3 with batching, editing, etc... (I have only to perform it once and for all), I don't see how to do the point 2: self-getting the tablename to insert into SQL. Have you an idea / or a different way to do that could solve my problem? Note: In fact, there are 250+ rX tables. That's why i can't do this manually. Note2: Precisely, this is with MySQL.

  • How to see full compile path in Eclipse?

    - by alleywayjack
    I have looked for an answer for this nearly every where that I can think of, but there doesn't seem to be any way to actually SEE what Eclipse "runs" to compile the projects (as it does need the JDK installed and visible to actually build). I ask because I imported a few jars into my project, and even though I've looked through all the javac documentation, I can't seem to figure out how to mimic it quite like Eclipse does. I really, really need to be able to compile on the command line in this case - Eclipse or any other IDE just isn't what is needed. I started to look through the Eclipse source, and although this sounds lazy, I just became overwhelmed and figured I would ask here first, hoping someone else had the same question at one point.

  • Marking up table joins in the Microstrategy project metadata with the architect tool?

    - by ConcernedOfTunbridgeWells
    Hi, I am evaluating Microstrategy 9.0.1 and attempting to build a prototype metadata layer using its Architect tool. The tool doesn't seem to have any specific means to mark up joins in the way that the editing tools for SSRS data source views or Business Objects universes do. How does this work in Microstrategy - I have never used this before and may be making invalid assumptions based on other systems I have seen. If one does do this with MicroStrategy, how is it done?

  • Merging two arrays in PHP

    - by Industrial
    Hi everyone, I am trying to create a new array from two current arrays. Tried array_merge, but it will not give me what I want. $array1 is a list of keys that I pass to a function. $array2 holds the results from that function, but doesn't contain any non-available resuls for keys. So, I want to make sure that all requested keys comes out with 'null':ed values, as according to the shown $result array. It goes a little something like this: $array1 = array('item1', 'item2', 'item3', 'item4'); $array2 = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3' ); Here's the result I want: $result = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3', 'item4' => '' ); It can be done this way, but I don't think that it's a good solution - I really don't like to take the easy way out and suppress PHP errors by adding @:s in the code. This sample would obviously throw errors since 'item4' is not in $array2, based on the example. foreach ($keys as $k => $v){ @$array[$v] = $items[$v]; } So, what's the fastest (performance-wise) way to accomplish the same result?

  • Flex 3 - Full unicode support fonts and CSS

    - by BS_C3
    Hi! I'm developping a web application that will be used either in Europe or in Asia (specially Japan -Hiragana, Kanji and Katana-, China and Korea). I'm using the following fonts: - ericssonga628.TTF - HelveticaNeueLTStd-Lt.otf - HelveticaNeueLTStd-LtEx.otf - HelveticaNeueLTStd-Bd.otf - HelveticaNeueLTStd-BdEx.otf When I tried to display Japanese characters, I don't get anything. I guess these fonts don't support East Asian characters... Do you know of any equivalent fonts? Also, I was thinking of creating a CSS for each language (or pack of languages) when the user changes the display language. For example, if the user selects "japanese", I'll use the japanese stylesheet. However, how do I switch from a CSS to another? Thanks in advance for your answers. Regards,

  • Including full LaTeX documents within others.

    - by Chris Clarke
    I'm currently finishing off my dissertation, and would like to be able to include some documents within my LaTeX document. The files I'd like to include are weekly reports done in LaTeX to my supervisor. Obviously all documents are page numbered seperately. I would like them to be included in the final document. I could concatenate all the final PDFs using GhostScript or some other tool, but I would like to have consistent numbering throughout the document. I have tried including the LaTeX from each document in the main document, but the preamble etc causes problems and the small title I have in each report takes a whole page... In summary, I'm looking for a way of including a number of 1 or 2 page self-complete LaTeX files in a large report, keeping their original layouts, but changing the page numbering.

  • How to give 'Everybody' full rights to a file (programmatically)

    - by egrunin
    I'm modifying an old C++ program to run on Vista. It does not require Admin privileges. I've changed the code to put logfiles in \ProgramData\MyApp\. These logfiles are written with the stdio functions (fopen, fprintf, fclose). Here's the problem: UserA runs the program first, it creates \ProgramData\MyApp\MyLogFile.txt UserB runs the program next, it tries to append to MyLogFile.txt and gets access denied. I tried creating a null SECURITY_DESCRIPTOR and passing that to CreateFile(). That does create a file with "no permissions assigned", but it seems as if the first user to write to the file takes ownership and afterwards all the other non-admin users are out of luck. It's important that all users share the same logfiles, but it's also important that I change as little code as possible.

  • PHP: Doctrine: order joined records

    - by Sebastian Bechtel
    Hi, I'm new to doctrine: I have a problem with the sorting of joined records. A sample. I've got an Article model which is associated with a Source model in 1 <- n. The source model has a property called 'position' with an integer value. Now I want to fetch an article with it's sources orderes by the position. My DQL looks like this: $q = Doctrine_Query::create() ->select('a.title, s.content') ->from('Article a') ->leftJoin('a.Source s') ->where('a.id = ?') ->orderBy('s.position'); The result doesn't change if I edit the position. Best regards, Sebastian

  • SQL COUNT records in table 2 JOINS away

    - by Fred K
    Using MySQL, I have three tables: projects: ID name 1 "birthday party" 2 "soccer match" 3 "wine tasting evening" 4 "dig out garden" 5 "mountainbiking" 6 "making music" batches: ID projectID templateID when 1 1 1 7 days before 2 1 1 1 day before 3 4 2 21 days before 4 4 1 7 days before 5 5 1 7 days before 6 3 5 7 days before 7 3 3 14 days before 8 5 1 14 days before templates: ID message 1 "Hi, I'd like to invite ..." 2 "Dear Sir, Madam, ..." 3 "Can you please ..." 4 "Would you like to ..." 5 "To all dear friends ..." 6 "Does any of you guys ..." I would like to display a table of templates and the number of projects they're used in. So, the result should be: templateID projectCount 1 3 2 1 3 1 4 0 5 1 6 0 I've tried all kinds of SQL queries using various JOINs, but I guess this is too complicated for me. Is it possible to get this result using a single SQL statement?

  • Oracle join issue

    - by acadia
    Hello, I have 3 tables and I am joining these 2 tables as follows: SELECT EMP.FNAME,EMP.LNAME,EMP.AGE,EMPD.TQ,EMPD.TA,CTY.CITY_NAME FROM EMPLOYEE EMP,EMPLOYEE_DETAIL EMPD, CITY CTY WHERE EMP.EMP_ID=EMPD.EMP_ID AND EMPD_CITY_ID=CTY.CITY_ID I want to display records even if City record is not in CITY table. For eg. if City_ID record for say 10 is not in City table but there is an employee detail record with City_id 10 it should display City_name as null instead of not displaying the record at all. Appreciate your help

  • Best way to do one-to-many "JOIN" in CouchDB

    - by mit
    There are CouchDB documents that are list elements: { "type" : "el", "id" : "1", "content" : "first" } { "type" : "el", "id" : "2", "content" : "second" } { "type" : "el", "id" : "3", "content" : "third" } There is one document that defines the list: { "type" : "list", "elements" : ["2","1"] , "id" : "abc123" } As you can see the third element was deleted, it is no longer part of the list. So it must not be part of the result. Now I want a view that returns the content elements including the right order. The result could be: { "content" : ["second", "first"] } In this case the order of the elements is already as it should be. Another possible result: { "content" : [{"content" : "first", "order" : 2},{"content" : "second", "order" : 1}] } I started writing the map function: map = function (doc) { if (doc.type === 'el') { emit(doc.id, {"content" : doc.content}); //emit the id and the content exit; } if (doc.type === 'list') { for ( var i=0, l=doc.elements.length; i<l; ++i ){ emit(doc.elements[i], { "order" : i }); //emit the id and the order } } } This is as far as I can get. Can you correct my mistakes and write a reduce function? Remember that the third document must not be part of the result. Of course you can write a different map function also. But the structure of the documents (one definig element document and an entry document for each entry) cannot be changed.
