• How to automatically generate associations in the EDMX using Entity Framework 'database first'?

  Hello.  I'm new on Entity Framework and the database that I connect Oracle 10 g.  I develop using Visual Studio 2015, ODAC 12 c version 4 with the installed Visual Studio Tools and EF 6.1.3.  I am generation an EDMX model from an existing database.  In the Visual Studio wizard, I select the existing tables that have relationships of foreign key between them.  The resulting EDMX contains the tables and their columns, but no association.  I tried to do this using the code first of all existing database Wizard, and the results are similar: classes for the tables and column properties, but still no association or the properties of a class to contain instances of another.  Should I be not expecting associations to be created automatically?  Is there something I missed?

  I'm back in it and found out what the problem was.  Before you create the entity data model, I had to have the connection already defined in Server Explorer * using the ODP.NET* provider.

• Tables of database error using Entity Framework mapping

  Hello!

  I am developing a project using the ODAC 11.2 module 4 and EF 5.0. I have the .edmx file and I had generated entities with EF 5.x DbContext generator model.

  The error occurs when trying to access one of the properties (postcode) of my entity 'address '. This column is a Number type (5) in the database, but it is mapped in the entity as the short type.

  I run this LINQ and I get the error: "the value was too large or too small for an Int16.

  var query = from b in the present. ADDRESS

  Select b.PC;

  Test of list < short? > = query8. ToList();

  I think it was a problem with the map. Could you help me?

  Thank you very much

  First, you must use ODAC 11.2 version 5 or higher. This version is certified with EF 5.

  Normally, Number (5) is mapped by default to an Int16. Not sure how you map it to a short circuit. In any case, if you explicitly want to map any type of data default data type, you can use the following mapping customization described here in the doc:

• Entity Framework stored procedure Mapping - OUT unrecognized parameter

  I use the following software:

  • ODP.NET 12 c Release 3
  • Entity Framework 6
  • Visual Studio 2013, SP3
  • Oracle 11g Server

  I created a package containing a stored procedure to update a row in a table.  The procedure is an OUT parameter (named ROWS_AFFECTED) which returns the number of rows affected.

  CREATE OR REPLACE PACKAGE BODY TST. Customer_Procs
  AS
  PROCEDURE Update_Customer
  (
  CUST_ID IN NUMBER,
  WHAT IN VARCHAR2,
  L_NAME IN VARCHAR2,
  EMAIL IN VARCHAR2,
  LAST_UPDATE TIMESTAMP IN
  ROWS_AFFECTED NUMBER
  )
  AS
  BEGIN
  UPDATE
  TST. CUSTOMER
  SET
  NAME = WHAT,.
  LAST_NAME = L_NAME,
  EMAIL_ADDR = EMAIL,
  LAST_UPDT_TIME = CURRENT_TIMESTAMP
  WHERE
  CUSTOMER_ID = CUST_ID
  AND LAST_UPDT_TIME = LAST_UPDATE;

  ROWS_AFFECTED: = NUMBER OF ROWS SQL %;

  END Update_Customer;

  
  I executed successfully the stored procedure in SQL * more.  The ROWS_AFFECTED OUT parameter is filled with the good

  value.

  I imported the stored procedure in my Entity Framework model using the function successfully import.

  I then traced the parameters of the stored procedure to my entity properties. The ROWS_AFFECTED parameter is shown in the stored procedure mappings, but the "rows affected parameter" check box is cleared.

  Attempt to run my results in the following exception being throw:
  "CustomerModel.msl (22,12): error 2047: a mapping liaison function specifies a function.

  CustomerModel.Store.CUSTOMER_PROCS_UPDATE_CUSTOMER with a parameter not supported: ROWS_AFFECTED. Output parameters cannot

  be mapped through the RowsAffectedParameter property. Use the result links to return values from a function call.

  I am trying to determine what I need to do in order to have the Entity Framework to recognize the ROWS_AFFECTED OUT parameter in the

  stored procedure chart for concurrency control.

  I found a solution: try to declare ROWS_AFFECTED such as 'PLS_INTEGER' instead of 'NUMBER '.  This solved it for me.

• Entity Framework no longer works! Help, please!

  Hello
  I did an apprenticeship with the help of EF4.1.0.0 and the new ODAC for the Entity Framework. I've been using Add new item in my project of MVC3 to add my database entities. I can select ADO.NET Entity Data Model and then I get the wizard dialog box for "select the template content". When I select "Create database" and press Next the next dialog box choose your connection comes sometimes, sometimes not--but in both cases the dialog box disappears, and there is no more to do. I tried to leave VS2010 ultimate and start over with a new project. The same problem. I tried to restart my pc and the same problem. VS2010 (which is a major pain) I uninstalled and reinstalled with SP1. However, the wizard is broken when selecting "Create database". I uninstalled the ODAC and rebooted and VS2010 and the Assistant EF works properly again (of course not for Oracle). I reinstalled the ODAC and tried again and the wizard explodes on her generate database. I can do anything is no longer working with ODAC.
  Has anyone of another seen elsewhere or knows how to solve this problem? This looks like a bug to me.
  
  Any suggestion would be appreciated!
  Kind regards

  I think that you are facing a known issue. See this existing post:
  Beta Vesrion ODP.NET with Entity Framework support
  You need to scroll up to the Center to see your problem that is described in the same way and then I post that Oracle suspects that it is a known problem with Visual Studio.

  An easy way to check if you have the same problem is to ensure that the first connection in Server Explorer is able to connect to a database. Not the first Oracle, the first connection connection to what either in Server Explorer. Once you verify that the first connection can connect, and rerun the EDM Wizard with Oracle. If it works now, it's the same question.

  This problem occurs with all providers of DB, Oracle not only. It's probably a generic problem with VS 2010 that MS would need to correct. However, the workaround is easy to use that it should not be a showstopper by using EF.

• My sata cd rom a problem after re-installation of WinXP Pro by this cd rom; error code 041; How do I solve this problem

  My sata cd rom a problem after re-installation of WinXP Pro by this cd rom; error code 041; How do I solve this problem

  It's almost certainly a driver problem.

  Please tell the service pack on your Windows® XP Pro level forum and the manufacturer and model of your system, if it is conditioned, or the make and model of your motherboard if it is not.  In addition, please tell us the manufacturer and model of the optical drive.

  First of all, if there is a system, go to the support Web site of the manufacturer for your system model.  If this is not a system, go to the support Web site of the manufacturer of the motherboard for your model of motherboard.  In the first case, you should find the drivers, chipset in particular drivers, updates and software for your system. Install all the that apply.  In the second case, you will find the drivers of integrated devices, chipset, updates and software for your motherboard drivers. Yet once, install all the that apply.  As we know nothing on the optical drive other it is attached via SATA, I can't talk about what to do there except that you should go to the manufacturer's support Web site and search for drivers and updated firmware for your model.

  It would have been helpful if you had provided more complete information on the installation of Windows, your system hardware and the optical drive.  The most complete information; more answers you will get.  Please, read:KB555375 - how to ask a question.

  Don't forget, no member of this forum is omniscient.

• error code 80096004 how to fix

  update of Windows has error code 80096004 how to remove

  Hi Gerald,

  If the spirit messages ae out of your reach, it's OK.  BSOD problems are difficult for even the best of us and sometimes even if we do all that is there and even more, we still do not solve the problem.

  I offer the following choices at this point (we'll talk about the order of them later):

  1. try an installation of repair as explained here: http://www.sevenforums.com/tutorials/3413-repair-install.html.

  2. try a clean install of Windows 7 (from scratch in essence).  If you move from Vista to Windows 7 with a upgrade disk, use this tutorial: http://www.sevenforums.com/tutorials/31402-clean-install-upgrade-windows-7-version.html.  If you move from Vista to Windows 7 with a full Installation disc, use this tutorial: http://www.sevenforums.com/tutorials/1649-clean-install-windows-7-a.html.  If you want to do a custom installation of Windows 7 instead of a clean install to preserve some of the old information on the system (which may be good or may retain the cause of the problem but this is rare), use this tutorial: http://www.sevenforums.com/tutorials/20146-custom-install-windows-7-a.html.

  3 do a more complete test of your hard drive to confirm that this is not a failure (as the loss of information like this, more past issues of BSOD makes be think bad hard drive).  To test your hard drive, check the manufacturer and try to diagnosis HD (http://www.carrona.org/hddiag.html) or this test: hard drive diagnostics tools and utilities (storage) - Corp of TACKtech (http://www.tacktech.com/display.cfm?ttid=287) or see if the manufacturer of the computer or the hard drive manufacturer have their own diagnostic utility you can download and run (which could be the best (, as it is sure to be very specific and current for this drive).  If it fails the test, replace it and then see option 2 above, making sure to add the appropriate when installing drivers.  If it is bad, it can fix everything once you reinstall everything.  On the other hand, even if it is bad, while replacing it will help and may be necessary anyway (or at least should be done if you intend to keep the computer), there is no 100% guarantee that it was the only problem or replacement can all solve.  It is likely, but not a guarantee.  You must decide if the cost is worth it to test a solution likely but not proven to a known problem but not necessarily or only behind the problems you encounter.  Of course, if it comes with a money back guarantee, making the choice a little easier because if it does not, you can always return it little or no cost.  But given your level of understanding, while trials may be possible, I suspect you will need help if turned out to be bad and you decide to replace it.

  4. find a reputable computer repair shop (not Geek Squad, but one that has true professionals, a long history and wonderful comments from reliable sources) or see if the computer manufacturer will repair it if you ship to them (and compare the cost, schedule, guarantees and other factors--like buying a place to fix television or a car).  A parent, friend, neighbour, who will do the work for free with you pay only for the parties can save money, but to ensure that this person doesn't REALLY know what he's doing and you select not based on your social interactions or dealing with someone who says he knows much more is actually true (and as all these choices that can turn out to be a great victory or a great regret - it may end up a lot cheaper) or maybe find themselves much more expensive as well as risk to your personal information or to do things which are only slightly hurt much more serious - but it is a risk in a way with whoever you choose).

  5. prepare to move this computer in the basement and start again with brand new and transfer computer only your important data to make sure that you don't move potentially cause old problems to the new computer.

  In some cases, you can try several of these options or, depending on your choice, one may be required.

  Given what you have said, I would say try option 4 if it can be done economically reasonable or it will cost almost as much as a new computer anyway, then go with option 5 (assuming that you have the money to one of these - a big assumption on my part that only you can decide to do).

  If you don't have that kind of money on hand (I of course know this feeling - LOL!), so I'd try just the part test option 3 to verify that the hard drive is OK (and hope it passes) and, if so, first try option 1 and if this does not work, then try option 2.  Of course if they are out of your reach, then to options 4 or 5 are really your only choice.

  Where do you live?  If the United States of America, in what state?  If Maryland, what city?

  I hope this helps.

  Good luck!

• Could not import the Pentecost Entity Framework stored procedures

  Hi, I have a problem with Entity Framework 5 and stored procedures. I can add stored procedures to mi with "Update Wizard" solution, but them does not show in the Model Explorer and I can't use my code. I have ODAC 12 c Release 2 installed in my pc.

  There is a bug in the database Oracle 12 c that occurs only with a snap-in database. It is fixed in the next group of patches from database. (bug #17448545)

  There are three workarounds in the meantime:

  (1) to re-create the database without the shared option (no plug-in database)

  (2) install your schema in the database of the container instead of a snap-in database. You will need a user name as C ##HR to do. It is not advisable on a production database.

  Add 3) the section of manually in in the edmx file. Note that this is deleted when you "Generate database from model" or "Update model from database".

  for example:

  ...

  ParameterTypeSemantics = "AllowImplicitConversion" scheme = "SCOTT" >

• Entity framework problem and the types of courts

  I use Entity Framework in Visual Studio to access a table in my oracle database. Problem is when you select a record in run mode, the following error appears:
  Value was either too large or too small for an Int16
  
  This error comes when trying to access a table declared as number field (5). The framework reflects this in a short runway. The max value for short is 32767, but the value in the table is 36001.
  
  I can solve this?
  
  Thank you.

  Yes, you must change the mapping of this type to an Int32. For this you can add this to your config file:

  
  
  
  
  
  

  You should then update the model for the new changes. Note that I found that I have to manually change the types in the model, but after I do this once it works fine. The documentation is here: http://docs.oracle.com/cd/E11882_01/win.112/e18754/featLINQ.htm
