  • Why Hibernates ignores the name attribute of the @Column annotation?

    - by svachon
    Using Hibernate 3.3.1 and Hibernate Annotations 3.4, the database is DB2/400 V6R1, running that on WebSphere 7.0.0.9 I have the following class @Entity public class Ciinvhd implements Serializable { @Id private String ihinse; @Id @Column(name="IHINV#") private BigDecimal ihinv; .... } For reasons I can't figure, Hibernate ignores the specified column name and uses 'ihinv' to generate the SQL: select ciinvhd0_.ihinse as ihinse13_, ciinvhd0_.ihinv as ihinv13_, ... Which of course gives me the following error: Column IHINV not in table CIINVHD Did anyone had this problem before? I have other entities that are very alike in the way that they are using # in their database field names and that are part of the PK and I don't have this problem with them.

  • Why can I create a table with PRIMARY KEY on a nullable column?

    - by AlexKuznetsov
    The following code creates a table without raising any errors: CREATE TABLE test( ID INTEGER NULL, CONSTRAINT PK_test PRIMARY KEY(ID) ) Note that I cannot insert a NULL, as expected: INSERT INTO test VALUES(1),(NULL) ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null). ********** Error ********** ERROR: null value in column "id" violates not-null constraint SQL state: 23502 Detail: Failing row contains (null). Why can I create a table with a self-contradictory definition? ID column is explicitly declared as NULLable, and it is implicitly not nullable, as a part of the PRIMARY KEY. Does it make sense? Edit: would it not be better if this self-contradictory CREATE TABLE just failed right there?

  • How to access website CMS with only access to database

    - by user1741615
    I have a website that uses an "in-house" cms and I don't know the login details. The platform itself doesn't have the "reset your password" functionality. I do have access to ftp and phmyadmin and I found the SQL table containing the user details, but of course the password is MD5 encryption. I tried manually creating a user in php my admin and filling in a password encrypted in MD5 (used a md service online for that), but it still doesn't work. Does anybody know other tricks I can use? Thanks.

  • How do you find the last element of an array while iterating using a foreach loop in php ?

    - by Vaibhav Kamble
    I am writing a sql query creator using some parameters. While doing that ,I came across this problem. In java , Its very easy to detect the last element of an array from inside the for loop by just checking the current array position with the array length. for(int i=0; i< arr.length;i++){ boolean isLastElem = i== (arr.length -1) ? true : false; } php has some different fashion. They have non integer indexes to access arrays. So you must iterate over an array using foreach loop. But it becomes very problematic when you need to take some decision (in my case to append or/and parameter while building query). I am sure there must be some standard way of doing this. How do you solve this problem normally in php ?

  • Hibernate Auto-Increment not working

    - by dharga
    I have a column in my DB that is set with Identity(1,1) and I can't get hibernate annotations to work for it. I get errors when I try to create a new record. In my entity I have the following. @GeneratedValue(strategy=GenerationType.IDENTITY, generator="native") @Column(name="SeqNo", unique=true, nullable=false) BigDecimal seqNo; But when I try to add a new record I get the following error. Cannot insert explicit value for identity column in table 'MemberSelectedOptions' when IDENTITY_INSERT is set to OFF. I don't want to set IDENTIY_INSERT to ON because I want the identity column in the db to manage the values. The SQL that is run is the following; where you can clearly see the insert. insert into dbo.MemberSelectedOptions (OptionStatusCd, EffectiveDate, TermDate, SelectionStatusDate, SysLstUpdtUserId, SysLstTrxDtm, SourceApplication, GroupId, MemberId, OptionId, SeqNo) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) What am I missing?

  • Which Visual Studio 2010 edition for sole developer

    - by bufferz
    I am the sole .net developer for a small company. My projects span many .net technologies including WinForms, WPF, SQL, XNA, Linq, WCF, WTF?, and others. I struggle staying on top of all these projects so I'm looking to make my life easier with the release of VS2010. Without a mentor I rely heavily on StackOverflow and whatever else Google comes up with. Should I convince my company to get an edition with an MSDN subscription? Is it one of those things where once you have it, you can't imagine life without it? What about the source control that comes with VS2010, do you all find it better than an SVN server? We're looking to hire another programmer this year, would I be best off getting a Team edition of VS2010 to be best prepared for that hire? Thanks!

  • Using SSIS, how do you read a datetime field into a variable that is of Data Type string?

    - by Mark Kadlec
    This one has bugged me for the longest time and a great question to ask the Stackoverflow users I think. I have a rather large SSIS flow that uses a string variable to store the datetime. I would now like to dynamically read the datetime value from the database, but how would you construct the SSIS to do this? My first obvious thought would be to simply execute a SQL task to get the datetime and store it in the variable, but got the "differs from the current variable type" error. Is there a simple way to convert the database datetime into a String variable? Any help from the community would be appreciated,

  • how to control textbox type to double in visual basic?

    - by fema
    Hi, I'd like to make a textbox that accepts only numbers, but not integer, but rather double. I've read here about e.Handled = Not Char.IsDigit(e.KeyChar) and it works, but again, it can be used only for integer, since it declines decimal point. Another thing I've read here is If Not Double.TryParse(TextBox2.Text, value) Then .... and it would work fine, except that it allows only decimal comma instead of point. I don't know whether it's because of my location settings (Hungary, we use commas instead of points), but I don't have any other idea how to solve my problem, and the SQL server I send my data uses decimal point. Thanks in advance.

  • Fluent NHibernate ExportSchema without connexion string

    - by Vince
    Hi all, I want to propose to user a way to generate database table script creation. To do this for now i use NHibernate ExportSchema bases on a NHibernate configuration generated with Fluent NHibernate this way (during my ISessionFactory creation method): FluentConfiguration configuration = Fluently.Configure(); ... Mapping conf ... configuration.Database(fluentDatabaseProvider); this.nhibernateConfiguration = configuration.BuildConfiguration(); returnSF = configuration.BuildSessionFactory(); ... Later new SchemaExport(this.nhibernateConfiguration) .SetOutputFile(filePath) .Execute(false, false, false); fluentDatabaseProvider is a FluentNHibernate IPersistenceConfigurer which is needed to get proper sql dialect for database creation. When factory is created with an existing database, everything works fine. But what i want to do is to create an NHibernate Configuration object on a selected database engine without a real database behind the scene... And i don't manage to do this. If anybody has some idea.

  • DJANGO complex modelling

    - by SledgehammerPL
    Hello. I have such model now: receipt contains components. component contain product. The difference between component and product is, that component has quantity and measure unit: eg. component is 100g sugar - sugar is a product. So I need to make lots of components to satisfy different recipes - 100g sugar is not equal 200g sugar I wonder if I can remodel it to kick off components - in pure sql it's rather easy, but I'm trying to USE django - not making workarounds. class Receipt(models.Model): name = models.CharField(max_length=128) (...) components = models.ManyToManyField(Component) class Component(models.Model): quantity = models.FloatField(max_length=9) unit = models.ForeignKey(Unit) product = models.ForeignKey(Product) class Product(models.Model): name = models.CharField(max_length = 128) TIA

  • .net, C# Interface between Business Logic and DAL

    - by Joel
    I'm working on a small application from scratch and using it to try to teach myself architecture and design concepts. It's a .NET 3.5, WPF application, and I'm using Sql Compact Edition as my data store. I'm working on the business logic layer, and have just now begun to write the DAL. I'm just using SqlCeComamnds to send over simple queries and SqlCeResultSet to get at the results. I'm starting to design my Insert and Update methods, and here's the issue - I don't know the best way to get the necessary data from the BLL into the DAL. Do I pass in a generic collection? Do I have a massive parameter list with all the data for the database? Do I simply pass in the actual business object (thus tying my DAL to the conrete stuff in the BLL?). I thought about using interfaces - simply passing IBusinessObjectA into the DAL, which provides the simplicity I'm looking for without tying me TOO tightly to current implementations. What do you guys think?

  • How do I hook all http get requests and distinguish downloaded (by standard download manager) files

    - by Ivan
    I want to write a Firefox add-on for advanced history tracking and bookmarking which will send URLs the browser meets during usage (and all the metadata available about the context) to a web service which will keep track of them storing in an SQL database for further access and analysis. I'd like to divide URLs tracked into 5 groups: those I explicitly click to bookmark, those I download by Firefox standard built-in download manager, all other URLs accessed, all URLs met on all viewed pages as hrefs, all other URLs mentioned in HTML sources of all viewed pages. Any ideas of how to get those in an extension?

  • How to deploy and secure an ASP.NET web app to be available to internal and outside users?

    - by Swoop
    My company has several web applications written in ASP.NET. We need to make these applications available to Intranet users as well as authenticated external users. Most of the features are the same for the two groups, though there are some extra features available to the Internal users. The two different sets of users would use a slightly different security setup... our internal people will be authenticated using LDAP against Exchange, whereas the external users will have accounts in SQL Server. What is the best approach for deploying our web apps? Should we deploy 2 copies to different servers, one configured for an Intranet and one for outside users? Or is there a better way to share the code between the 2 servers, yet have the flexibility to use different web.config settings for security??

  • QT4, paginated showing elements

    - by matiit
    I am going to write an application that uses QT4 (with C++ or python it isnt important in that moment). One of functionality is "Showing all items in database". One item has a Title, author, description and photo (constant size) And there could be very many items. Let's say 400. There won't be enough space to show'em all at once time. One row will have 200px, so i need at most 4 for once time. How to paginate them? I have no idea. I can use limit and offset in SQL queries, but how to tell window: "that's 5th page"? Any solutions?

  • Chunks of javascript added to webpages on server

    - by SteD
    I've found out that my web pages (mainly index.php, main.html, include.inc) have been injected with a chunk of javascript codes at the very bottom after my original code. <script>try {this.l="";var d=window[unescape("%75%6e%65%73%63%61%70%65")];var M;if(M!='' && M!='a'){M='bt'};var A="";var Mc=new String();var e=null;this.k="";var t;if(t!='' && t!='iX'){t=''};var K=window[d("%52%65%67%45%78%70")];var p=d("%72%65%70%6c%61%63%65");function C(H,Z){var N=d("%5b" Is it possible for SQL injections to add the chunk of js code to the webpages(like 50 of them are infected)? Or is it a virus on the server itself? I am using Drupal + Ubercart with quite minimal forms inputs.

  • any ways saving user information without db

    - by hguser
    Hi: I have a application which require login,but the number of user who use the application is no more than 40. And In the application,I get some data from the sql server database where I juse have read permission,also I can not create a table in the db for user validate. ALso I do not think it is a good idea to create a user table in other database on another machine.(for example,I can create a user table in the mysql another machine,but is it desireable just for user validating)? Now I just save the user info in a .properties file,any other good idea? BTW,the programe language used in my application is java.

  • MySQL Prepared Statements vs Stored Procedures Performance

    - by amardilo
    Hi there, I have an old MySQL 4.1 database with a table that has a few millions rows and an old Java application that connects to this database and returns several thousand rows from this this table on a frequent basis via a simple SQL query (i.e. SELECT * FROM people WHERE first_name = 'Bob'. I think the Java application uses client side prepared statements but was looking at switching this to the server, and in the example mentioned the value for first_name will vary depending on what the user enters). I would like to speed up performance on the select query and was wondering if I should switch to Prepared Statements or Stored Procedures. Is there a general rule of thumb of what is quicker/less resource intensive (or if a combination of both is better)

  • ShapeFile with Z Co-ordinates

    - by ace_mccloud
    I have 3 shapefiles, two of them wihtout the Z Co-ordinates elevation but 1 of them has a Z co-ordinate elevation. I can load two ShapeFiles into my SQL Server Database which does not have Z Co-ordinates. But I am having issue loading the Z Co-ordinate file into the database. I have been reading different forums and got a suggestion that I need to trim the Z coordinates(chnage 3D to 2D) to load into the database. I was just wondering how can I achieve this? Can anyone suggest free tools or any method to do the same? Cheers, Rushir
