  • Synchronize model in MySQL Workbench

    - by Álvaro G. Vicario
    After reading the documentation for MySQL Workbench I got the impression that it's possible to alter a database in the server (e.g. add a new column) and later incorporate the DDL changes into your EER diagram. At least, it has a Synchronize Model option in the Database menu. I found it a nice feature because I could use a graphic modelling tool without becoming its prisoner. In practice, when I run such tool I'm offered these options: Model Update Source ================ ====== ====== my_database_name --> ! N/A my_table_name --> ! N/A N/A --> ! my_database_name N/A --> ! my_table_name I can't really understand it, but leaving it as is I basically get: DROP SCHEMA my_database_name CREATE SCHEMA my_database_name CREATE TABLE my_table_name This is dump of the model that overwrites all remote changes in my_table_name. Am I misunderstanding the feature?

  • Fluent NHibernate - How to map a non nullable foreign key that exists in two joined tables

    - by vakman
    I'm mapping a set of membership classes for my application using Fluent NHibernate. I'm mapping the classes to the asp.net membership database structure. The database schema relevant to the problem looks like this: ASPNET_USERS UserId PK ApplicationId FK NOT NULL other user columns ... ASPNET_MEMBERSHIP UserId PK,FK ApplicationID FK NOT NULL other membership columns... There is a one to one relationship between these two tables. I'm attempting to join the two tables together and map data from both tables to a single 'User' entity which looks like this: public class User { public virtual Guid Id { get; set; } public virtual Guid ApplicationId { get; set; } // other properties to be mapped from aspnetuser/membership tables ... My mapping file is as follows: public class UserMap : ClassMap<User> { public UserMap() { Table("aspnet_Users"); Id(user => user.Id).Column("UserId").GeneratedBy.GuidComb(); Map(user => user.ApplicationId); // other user mappings Join("aspnet_Membership", join => { join.KeyColumn("UserId"); join.Map(user => user.ApplicationId); // Map other things from membership to 'User' class } } } If I try to run with the code above I get a FluentConfiguration exception Tried to add property 'ApplicationId' when already added. If I remove the line "Map(user = user.ApplicationId);" or change it to "Map(user = user.ApplicationId).Not.Update().Not.Insert();" then the application runs but I get the following exception when trying to insert a new user: Cannot insert the value NULL into column 'ApplicationId', table 'ASPNETUsers_Dev.dbo.aspnet_Users'; column does not allow nulls. INSERT fails. The statement has been terminated. And if I leave the .Map(user = user.ApplicationId) as it originally was and make either of those changes to the join.Map(user = user.ApplicationId) then I get the same exception above except of course the exception is related to an insert into the aspnet_Membership table So... how do I do this kind of mapping assuming I can't change my database schema?

  • use of EntityManagerFactory causing duplicate primary key exceptions

    - by bradd
    Hey guys, my goal is create an EntityManager using properties dependent on which database is in use. I've seen something like this done in all my Google searches(I made the code more basic for the purpose of this question): @PersistenceUnit private EntityManagerFactory emf; private EntityManager em; private Properties props; @PostConstruct public void createEntityManager(){ //if oracle set oracle properties else set postgres properties emf = Persistence.createEntityManagerFactory("app-x"); em = emf.createEntityManager(props); } This works and I can load Oracle or Postgres properties successfully and I can Select from either database. HOWEVER, I am running into issues when doing INSERT statements. Whenever an INSERT is done I get a duplicate primary key exception.. every time! Can anyone shed some light on why this may be happening? Thanks -Brad

  • How to set up hibernate to use Glassfish connection pool?

    - by jschoen
    I have set up a connection pool in Glassfish with a jndi resource for it also setup. I am stumped on how to configure hibernate to go get it. I have come across alot of write ups to configure it to use C3P0 connection pool. Well I am lost. I found that I need to set: hibernate.connection.datasource hibernate.jndi.url hibernate.jndi.class hibernate.connection.username hibernate.connection.password Would datasource be the same as the hibernate.connection.datasource set in the connection pool? What would hibernate.jndi.class be? Are hibernate.connection.username and hibernate.connection.password for the connection to the database or to the appserver? I assume this is to the database, but why do I need them since that is all set in the appserver?

  • Jquery galleryView loading issues: loader image not displaying, taking awhile

    - by Dustin
    I've got an online portfolio that I'm putting up: Image Gallery I've got a php script that selects at most 15 images from a database that contains the urls for the images. e.g. foreach ($database-result as $img) { echo '<a href="path/to/image/' . $img . '">'; ? When the page first loads, the scroll bar expands as if it is loading invisible images (indeed I think that's what it is doing). Then the javascript kicks in and the gallery loads. I have two questions: first, the image loader is not displaying at all. I don't mind if it takes a bit, as long as the user knows the images are loading. Any ideas why it's not showing up? Second, is there a way to speed up the process? Thanks in advance for the help!

  • How should one import large amounts of data for FIT/Fitnesse tests?

    - by Lachlan
    We have a scheduling engine with large amounts of test data to test all the scenarios, so test automation is critical. We're currently hoping to use FIT/Fitnesse. However a single test has quite a large table of test data, so it doesn't fit very well into the mould of "two or three inputs, one or more outputs" that Fitnesse uses in its examples. Hopefully the other functionality of Fitnesse makes it worth using it. I hear that there is a way to initialize an application for a FIT test with an Excel spreadsheet - not the Spreadsheet to Fitness function, mind you - but I haven't been able to find it so far. Once the whole spreadsheet is loaded into the application, and the application does its thing, we plan to compare either a number of output rows, or perhaps just the last row, to see if the test passes. The application is currently pulling test data from a database for manual tests, but writing to a database, then initializing from it, is not preferred because of the performance impact. The application is written in C#.

  • Naming conventions and field naming question for CakePHP

    - by jphenow
    Okay so two questions very related: 1) Does following the naming convention for classes, controllers, database fields, etc. affect the framework's ability to work the way it was intended? (I'm a little new to working with a framework from the beginning of app development) 2) This question is more important if 1 is a yes. Say I have a table, A, that has 2 foreign keys pointing at the same table, B, but different entries (they're like edges of a graph that point at two vertices) how would I follow the naming convention of their database fields? All I can think to do is something like vertex_1_id and vertex_2_id but I don't know how the framework would handle that if the naming conventions are necessary for its functioning correctly.

  • Drupal node_save and special characters.

    - by Pierre
    Hello, i'm trying to create nodes and taxonomy terms through a custom php script by using the node_save() function. I'm working on drupal 6. It's working well (thanks to previous questions on stackoverflow) except for accented letters. Indeed, when a title or a taxonomy term contain "é", "è" or "à", the sentence is cut before those special characters. For example, a title like that: "Bonjour les éléphants" will create a node with "Bonjour les " as title. I don't know if it's linked to my database or if i have to use a special encoding in php (iconv() blabla) The fact is, for drupal titles, i can not use html encoding (for example: é is é in html) because drupal will render &eacute and not é... When i create a taxonomy or a title manually, i have no problems and the accented letter is saved in the database as "é". Soo if you can help me to create terms and title with accented letters, that will be great : ) Thank you !

  • Why does GetSqlDecimal throw when GetDecimal doesn't?

    - by I. J. Kennedy
    I have a database table that has a column of type money, allowing nulls. Using a SqlDataReader named reader, I can do decimal d = reader.GetDecimal(1); which works, unless of course we're reading a null. If I try using SqlDecimal instead--and I thought the whole point of the SqlTypes was to deal with nulls--then I get an invalid cast, whether or not the value is null. SqlDecimal s = reader.GetSqlDecimal(1); // throws an invalid cast exception What am I doing wrong? Do I really have to write a conditional statement to shepherd the value from the database to a SqlDecimal variable?

  • Silverlight standard loading animation does not get displayed.

    - by Anne Schuessler
    Can anybody enlighten me as to how the standard Silverlight loading animations (the swirling blue balls) are embedded in a Silverlight application and how they work? I currently don't see it although loading the xap takes long enough for the loading animation to be displayed. The problem is that I'm creating a xap dynamically and trying to write it to the Response Stream which might somehow interfere with the way most Silverlight applications work. So maybe there's something missing from the original aspx page or ClientBin that should be there that has been lost by accident. I haven't found any helpful information about how the loading animation is integrated into Silverlight that could help me debug the problem so far. Does anyone know what the animation needs to triggered as expected?

  • Is there anything RAD comparable to VCL?

    - by mawg
    After years in embedded programming, I have to develop a Windows app. I dug out my old C++ Builder and Delphi. These are great and the latest version costs over $1k, so I won't be going there. What I prarticularly like is the VCL (visual component library) which let's me code my own components and share them with others, plus the thousands of existing 3rd party components. I noticed that there is now also a RAD PHP from Borland too. I realzie that MSVC, QT, NetBeans, etc are good enough IDEs for RAD, BUT does anything offer the ease of the Borland products for developing additional components - and does anything else have thousands to choose from? PC based? Cross-platform is good. Browser based? Free is always good ;-) I don't particularly care about the programming language.

  • Fastest distance lookup given latitude/longitude?

    - by Ryan Detzel
    I currently have just under a million locations in a mysql database all with longitude and latitude information. With this I use another lat/lng to find the distance of certain places in the database but it's not as fast as I want it to be especially with 100+ hits a second. Is there a faster formula or possibly a faster system other than mysql for this? The formula I'm using is this. select name, ( 3959 * acos( cos( radians(42.290763) ) * cos( radians( locations.lat ) ) * cos( radians( locations.lng ) - radians(-71.35368) ) + sin( radians(42.290763) ) * sin( radians( locations.lat ) ) ) ) AS distance from locations where active = 1 HAVING distance < 10 ORDER BY distance;

  • Include OpenX ad in a jquery-ui dialog?

    - by planetclaire
    I'm loading some content into a jquery-ui dialog via .ajax. That's all working fine but now I've been given an OpenX ad to embed into the dialog & can't figure out how to do it. I know all the script is stripped when coming in via ajax, & I know how to use $.getScript to load .js files for use in the dialog, but the OpenX ad script I've got uses document.write so I think it's expecting to be embedded inline into the desired position on the page. I've tried appending the escaped script string into the div on ajax success of the main content as below, but this results in the page being redirected to a page with just the ad on it. Attempt shown below: $("#" + idHelpPage).find(".adScript").append("<script type='text/javascript'>var m3_u = (location.protocol=='https:'?'https://d1.openx.org/ajs.php':'http://d1.openx.org/ajs.php');var m3_r = ... etc etc I'm ok with jquery but not great with javascript, would really appreciate any help! Also if you want to see any other code.

  • IEditableCollectionView.AddNew() Throwing ArgumentNullException

    - by Eugarps
    In the context of Silverlight RIA using DomainContext and, the code as follows: private void AddProductButton_Click(object sender, RoutedEventArgs e) { var target = (Web.LocatorProduct)((IEditableCollectionView)ProductSource.DataView).AddNew(); target.Locator = LocatorID; target.Product = NewProduct.Text.ToUpper(); ((IEditableCollectionView)ProductSource.DataView).CommitNew(); } Is throwing ArgumentNullException in AddNew(), CreateIdentity() further up on the stack (a generated method) due to product being null. Product and LocatorID are, in combination, the primary key. I'm guessing that EF is not allowing me to generate a new item without meeting database contraints? How does this make sense if I need to obtain a primary key from the user? I have control over all tiers of the application, so suggestions on database design if needed are also welcomed.

    Hello! I'm diving into the world of prolog headfirst but I seem to have hit shallow water! I'm looking at database manipulation in prolog with regards to this tutorial:Learn Prolog Now! It states that I can see my database by entering listing So i tried it and it should basically output everything in my .P file(facts, rules), but this is what i get, here are my sequence of commands: ? consult('D:\Prolog\testfile.P'). [testfile.P loaded] ? listing. library_directory(C:blahblahpathtoXSB) library_directory(C:blahblahXSBpath) {this is listed around 5 times)} shouldn't this command display what is in testfile.P, according to the tutorial? also, after consult testfile.P i should be ableto use assert to add more facts but it doesnt actually change anything in the testfile.P..? any ideas

  • Invalid UTF-8 for Postgres, Perl thinks they're ok

    - by gorilla
    I'm running perl 5.10.0 and Postgres 8.4.3, and strings into a database, which is behind a DBIx::Class. These strings should be in UTF-8, and therefore my database is running in UTF-8. Unfortunatly some of these strings are bad, containing malformed UTF-8, so when I run it I'm getting an exception DBI Exception: DBD::Pg::st execute failed: ERROR: invalid byte sequence for encoding "UTF8": 0xb5 I thought that I could simply ignore the invalid ones, and worry about the malformed UTF-8 later, so using this code, it should flag & ignore the bad titles. if(not utf8::valid($title)){ $title="Invalid UTF-8"; } $data->title($title); $data->update(); However perl seems to think that the strings are valid, but it still throws the exceptions. How can I get perl to detect the bad UTF-8?

  • iPhone SDK mySQL

    - by Kevin
    Hello everybody, I'm starting on a new iPhone project, and this application mostly relies on mySQL. I have a mysql database running on my computer, and I need this application to send queries to the server to gain information. One example is creating and logging into an account. I have successfully done this on my windows vb.net application, but I know that objective c will be harder. This is basically getting text from the sql database and displaying it on the iPhone application. If someone could simply help me on that, I'll easily get started. So I hope that you guys help me out here :). Thanks Kevin

  • suggestions for Membership in ASP.NET MVC application

    - by mare
    With this question I am mostly looking for answers from people that have implemented the out-of-the-box ASP.NET membership in their own database - I've set up the tables inside my database and as far as I can see they contain mostly what I need but not everything. I will have the notion of a Firm (Company) to which Users will belong so I will have to associate the aspnet_Users with my Firms table (each user will be a member of exactly one firm). If possible, provide some guidelines how did you do it and what I might run into if I have to modify the table design at some point in the future. Preferably I will be using the default Membership provider. I am having trouble to decide whether to go from scratch or use what ASP.NET already offers.

  • Text editor with spell checker that ignores (X)HTML/CSS/javascript tags?

    - by Luis Soeiro
    Do you know of any text editor that can be used with a spell checker which is smart enough to ignore XHML/CSS and javascript tags? The requirements would be: It must run in Linux; It must be free and open source; It doesn't need to have WYSIWYG capabilities, but they would be welcome. It must have built in "tag skipping" capabilities or be configurable to skip (X)HTML tags, CSS and embedded Javascript; It doesn't need to have a HTML validator, but if it does it will be a plus; I've tried to use spell checker plugins for Kate, HTML validators for Firefox, Eclipse's HTML editor, but I couldn't find a solution that have a speel checker that ignores hml tags. Thanks for any help, Luís
