Hibernate mapping XML files for the two SQL Server tables below.

Hello all..,
Question 1:
I am working on a project that needs to support a database with an inherited legacy schema that you cannot change. The schema is provided below.Hibernate mapping XML files for the two SQL Server tables below. Please provide those two XML files. Assume some hypothetical package and class names. Assume that no "fancy" stuff such as lazy initialization, optimistic locking etc is needed at this time.
CREATE TABLE [SURVEY_ANSWERS] (
[ANSWER_ID] [int] IDENTITY (1,1) NOT NULL,
[QUESTION_ID] [int] NOT NULL,
[POSITION] [int] NULL,
[TEXT] [varchar](350) NULL
CREATE TABLE [dbo].[SURVEY_QUESTIONS] (
      [QUESTION_ID] [int] IDENTITY (1, 1) NOT NULL ,
      [TEXT] [varchar] (350) NULL
GO
ALTER TABLE SURVEY_ANSWERS
ADD CONSTRAINT pk_SURVEY_ANSWERS PRIMARY KEY(ANSWER_ID,QUESTION_ID);
ALTER TABLE [dbo].[SURVEY_QUESTIONS] ADD
       PRIMARY KEY  CLUSTERED
            [QUESTION_ID]
GO
ALTER TABLE [dbo].[SURVEY_ANSWERS] ADD
       FOREIGN KEY
            [QUESTION_ID]
      ) REFERENCES [dbo].[SURVEY_QUESTIONS] (
            [QUESTION_ID]
      )Question 2:
Assume that you are working on a project developing, say, a banking application. You are the Architect and thinking that Hibernate ORM should be used for the entire access to the relational database. As usual, you have created (or auto-generated) a set of HBM XML files as well as POJOs for which you define the mappings. Assume now that a new requirement has just popped up. The system needs to be able to import new bank accounts and user information in bulk from a very large XML file at once and store it in the database. Assume the XML file contains all necessary information to populate fields in database tables. As performance is very important for this operation. Given this description, how would you approach the problem?
Please describe briefly.
-Thanks and regards

  • Mutiple mapping XML files for one datasource

    One of our projects raised the following question. Any help would be greatly appreciated.
    "Can we have mutiple ToplinkMappings.xml files for one database? The reason we are looking at it is, our toplinkMappings.xml file size is keep growing in size(right now 2.2MB), we are getting into issues while comparing with the previous versions. The PVCS diff tool and beyond compare tools are not able to interpret the corresponding blocks of code on both the versions properly."

    Yes, you can have multiple deployment.xml files in a session. Take a look at Configuring Multiple Mapping Projects.

  • Unable to recreate replica as I cannot delete the xml files for the old VM on Hyper-v Cluster

    My setup
    There are 2 sites each running a Hyper-v 2012-R2 cluster comprising of 5 nodes each.
    All the machines are in a HA state and stored on the shared clustered resource.
    Initially we had replication working and it was replicating all the servers from Site A to Site B
    There were some replication issues which needed me to stop the replication and redo it again, in doing so I firstly removed replication on Fail-over cluster manager on Site A and did the same on Site B.
    On one of the servers I had to remove the VM, although the VM config and Disks still remain on the Site B Cluster.
    I was trying to recreate the replica but it always fails with the following error :
    Hyper-v failed to enable replication for virtual machine xxxxxxxx operation aborted (0x80004004).....
    I followed an article to stop the Hyper-V Virtual Machine Management Service and try delete the file,
    When i tried to stop the service it would restart automatically and I was unable to delete the file. I put the service in disabled which kept it stopped however I was still unable to delete the files. I also tried to get File assassin which can help delete
    and clear locked files but it too was unable to delete it while the service was running or stopped as well as its additional mode whereby it will delete it on next reboot.
    The  Article Https://social.technet.microsoft.com/Forums/windowsserver/en-US/4c4f2535-81ee-4a21-a920-b5632de2be37/hyperv-old-vm-folders-cannot-be-deleted?forum=winserverhyperv
     makes mention of stopping another service Hyper-V
    Image Management Service but I am unable to find it on 2012-R2 server.
    I have also tried to put the additional nodes in a paused drained roles state leaving only one node as the active one but it still will not let me delete the VM config
    files, without removing those files I cannot re-initiate the Replication.
    Any assistance would be greatly appreciated.

    Can you storage migrate any other vms or resources off of the CSV that contains the XML file in question? If so you may be able to then take that CSV offline, remove it from available storage, re-add as available storage, and add to CSV Volumes. Maybe
    that will clear your lock. 

  • How to study for the MCSA: SQL Server Exams?

    Hi guys, 
    Forgive me if this question has already been answered but I'm simply trying to find out the best way to tackle the three exams required for the MCSA in SQL Server. I read a blog post on the Pluralsight website which, in discussing the MCSA in Windows
    Server, it was advised that the best approach is to study for all three exams rather than one at a time as there's a certain amount of overlap.
    My question is does this apply to SQL Server 2012 too? Or would it be bets to study for, and take, the three exams separately and one at a time? I'm just completing the Trainsignal (now Pluralsight) SQL Server 2012 Administration Essentials 28-video course
    and was just about to begin going through the equivalent book when I read the blog post.
    My background is mainly in desktop/server support (10years following an IT degree) and before now, have had no real exposure to SQL Server. I was asked about a year ago by my current manager to "keep an eye" on the SQL instances we have and began
    by replicating the our fail-over cluster in a virtual environment for testing purposes and to gain an understanding of the set-up. I've since developed a keen interest in SQL Server and plan to get certified...  
    Many thanks in advance.
    Marcus.

    Hello,
    My humble recommendation is to study for each exam one at a time. I found 70-461 most difficult exam of SQL Server I have
    taken to this date for its XML content and the extent of the exam. Go for 70-461 first.

  • Setting date format for the entire SQL Server installation - SQL Server 2008 R2-2012

    Hi,
    I need to safeguard the behaviour of SQL codes that inserting into SQL tables with some date columns. For this purpose, I need to change the date format for the SQL instance and not using CONVERT and CAST.

    The language setting is related to the database user.

    Specifies the default language for the new user. If a default language is specified for the user and the default language of the database is later changed, the users default language remains as specified.
    If no default language is specified, the default language for the user will be the default language of the database. If the default language for the user is not specified and the default language of the database is later changed, the default
    language of the user will change to the new default language for the database."

    The default language setting can be overridden by SET LANGUAGE for the session:

  • How to save 150MB BLOB file in the database(SQL server)?

    Dear experts,
    I have written some code to save BLOB into a MS SQLserver7.0 database as follows:
    PreparedStatement ps=connection.prepareStatement("INSERT INTO jdbctest" + "(id, content, image) VALUES (?,?,?)");
    ps.setString(1,"2");
    ps.setString(2,"L11.avi");
    ps.setObject(3,data);
    It works for upto 12MB but for files that are as big as 150MB I always get an SQLException as follows,
    "Exception in thread "main" java.lang.OutOfMemoryError
    <<no stack trace available>>" .
    The SQLserver7.0 database is running on NT server 4. The client machine is SGI UNIX. I'm using i-net JDBC driver.
    It seems I should break the BLOB into chunks before saving into SQLserver but I don't know how to do it.
    Can someone please advise?
    THANKS!
    Yu

    Could you tell me more about it? Thanks.Depends on the application.
    For example for internal use you can set up a shared drive and then everyone gets a mapped read only access to it. Then you use a direct drive reference.
    For external, or just wider internal distribution, you could set up a ftp server. Then the address is just an ftp address.
    I believe there are other variations which can be implemented via browsers and support by the websever. For example loading a word doc via the browser.
    The advantage to the above is that you don't have to push it into the database and it allows for some more flexible storage alternatives. The disadvantages are all the things you might want a database for - like concurrency checking and a single source.

  • Newbie Question: Gererating a mapping xml file

    How is castor used, if even, to generate the mapping xml files from the classes generated by castor from an xsd? I have a(n) xsd that has many complex types and this called for the generation of many castor classes from that xsd...so, using these class files...how do I generate a single mapping xml file?
    Here is the means by wich we use these two (the xsd and mapping file) in one of our methods?
    xmlWriter.write(req, res, someDetail, "someDetail.castor.xml",
    "someDetail.xsd");
    Prior to this, the xsd files were simple and I created the mapping file by hand. I don't know how this translates when there are so many classes that were generated by caster.
    Can someone point me in the direction of more information on how to create this mapping file from all of these classes?
    Any advice would be appreciated.

    Can do... I have been working on a readme.install to this end.  One question about the pre_upgrade script.  /usr/share/pacman/proto.install states:
    ## arg 1:  the new package version
    ## arg 2:  the old package version
    #post_upgrade() {
      # do something here
    I'm confused by the arg 1 and arg 2.  Is it simply the version number with nothing else.
    EDIT: ok.. I get it,  Assign a variable to them to capture and check.
    # $1: The new package version

    What should I do with it? My first version of the camera will have 2 funcions: turn it on and turn it off I am bit confused, because the xml file template has lots of functions, that I don't really need. Should I delete them? Or leave inside with default values? What does minimal configuration XML file need?

    Thank you very much! Perhaps I was too concentrated on digging through various documents and missed the important info.
    And one more question: how does NI software build the *.icd file? By reading XML file? Or by reading registers in my camera? 
    Both. The XML is processed by the GenApi software component which then translates it to register operations. The XML file thus controls what features are visible based both on the XML file as well as the camera registers (features in the XML may be conditionally available based on the <pIsImplemented< tag). Next, the IMAQdx ICD file contains the subset of features in the XML file that are available and are tagged as <Streamable>, meaning they can be saved to a settings file.

    Hi Marcus,
    the following link is to the JNet/JGantt developer doco
    [JNet/JGantt Developer Documentation|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/lw/uuid/f010ec31-9658-2910-3c83-c6e62904eceb]

    You can use this to build XML to represent a gantt like chart.
    I did this to build XML to represent employee avaliablity - although we fronted the gantt through WD Java not ABAP - the java applet called is the same (I believe).
    Don't underestimate the work required to tweek your data into a decent layout. It took me days.
    There may be tools/api to help generate the XML - I don't know of them - I'd look forward to seeing any other replies to this thread from people who have used/built any.  An example of a class that generates JNet XML - CL_SPI_UI_JNET - but this does not seem to be a Gantt display.
