• Partitions don't synchronize only not - Oracle SQL Developer 4.1.3.20

  Hello

  First of all, thanks a lot for developers for this great tool.

  I use the Data Modeler which comes with Oracle SQL Developer 4.1.3.20.

  In the 12 c database, I created the following table:

  CREATE

  TABLE MMOURA. TEST_TABLE

  (

  NUMBER OF ID_TEST_TABLE (10) NOT NULL

  DATE_TEST_TABLE DATE NOT NULL

  )

  ORGANIZATION HEAP PCTFREE 10

  LOGGING NOCOMPRESS NO INMEMORY

  NOCACHE NOPARALLEL NOROWDEPENDENCIES DISABLE THE MOVEMENT OF THE LINE;

  I import with Data Modeler and add the partition:

  CREATE

  TABLE MMOURA. TEST_TABLE

  (

  NUMBER OF ID_TEST_TABLE (10) NOT NULL

  DATE_TEST_TABLE DATE NOT NULL

  )

  ORGANIZATION HEAP PCTFREE 10 TABLESPACE SYSTEM NOT LOGGING NOCOMPRESS NO INMEMORY RANGE PARTITION

  (

  DATE_TEST_TABLE

  )

  INTERVAL OF

  (

  NUMTOYMINTERVAL (1, 'MONTH')

  )

  (

  PARTITION P_BEFORE_2010 VALUES LESS THAN (TO_DATE (JANUARY 1, 2010 ',' DD/MM/YYYY "")) NOCOMPRESS

  )

  NOCACHE NOPARALLEL NOROWDEPENDENCIES DISABLE THE MOVEMENT OF THE LINE;

  So I can create a partition and generates the correct code.

  I click on "Synchronize data dictionary with model" and see the differences with the model and the database.

  In the models 'compare', 'Physical Details' is red. 'Partition' is red, "Selected" are marked, "Source table: TEST_TABLE ' is YES and" target Table: TEST_TABLE "is no.

  "Partitioning" is marked, and I can see the new partition "P_BEFORE_2010."

  

  But when I click on 'Overview of DOF', theres no changes:

  -Generated by Oracle SQL Developer Data Modeler 4.1.3.901

  -in: 2016-01-14 14:19:50 BRST

  -Oracle SQL Developer Data Model Summary Report:

  In the tool preferences, model, synchronization, it is marked:

  In "Import Options", it is marked:

  What I am doing wrong? Is this some sort of bug?

  Hi Marcio,

  I'm afraid that data Modeler does not "DOF Preview" statements for changes in the distribution.

• x 64 application entity Framework using Oracle.DataAccess.Client

  I am trying to build a x 64 application Entity Framework using the current Oracle.DataAccess.Client.  I can launch the application as Any CPU and x 86 using the managed provider, but when I compile for x 64, I get the error below when running. If I change the provider to Oracle.ManagedDataAccess.Client it works with x 86 and x 64 compiler.  Unfortunately, we are unable to use the managed provider until the xml is supported.  I have two clients x 86 and x 64 installed.  Any ideas?

  Alex,

  Finally, we have solved the problem.  It turns out that we had a bad x 64 home path in the PATH variable.  I lost track of what it was originally, but I'm sure the x 64 bin path was correct. I did not notice that it was wrong, until I tried to install the full client and began to see an error indicating that it was missing a dll.  This led me to a post on the forum, in which you indicated that the PATH variable has not been set (ODAC 12 c for xcopy issues).  In our case, it is not missing, just fake.

  This is the behavior that we see if the PATH variable for the home directories and bin is incorrect:

  • Full client: an error of external system (no exceptions).  The error message is that the oraons.dll is missing.
  • XCOPY customer: generates an exception without error message.  The Exception.Message property is empty and there is no inner exception.

  Can the ODP team can add a meaningful message for this exception?  If the exact error cannot be highlighted during execution, a generic name on the path audit would help enormously.  I must have looked at it a dozen times and didn't notice that it was false.  If I had no idea that this could be the cause, it would be discussed more in detail, or had someone else Verify that it was correct.  I hope that we would have solved much earlier.

  Thank you.

• 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.

• Oracle generates invalid WSDL

  Hi, guys!
  I use XML DB native Web Services of the project.
  The type of input parameters for my duties are "Object Types".
  But when I have an attribute in one object type to another object, the wsdl document which generates the Oracle is not valid.
  
  CREATE or REPLACE TYPE name_tp AS OBJECT)
  first name varchar2 (20).
  ......)
  
  CREATE or REPLACE TYPE person_tp AS OBJECT)
  name_tp person_name,
  .......)
  
  create or replace function test (p_person person_tp)
  ......
  
  When I have this situation, the wsdl file is not valid, because Oracle generates sth like this
  < xsd: element name = "person_name" type = "name_tp" / >
  Instead of
  < xsd: element name = "person_name" type = "tns:name_tp" / >
  
  How can any ideas, I solve this problem?
  
  Which is profound,
  Slavi

  The problem with the type being is not in the correct namespace is bug 8274288. You need to upgrade to 11.2.0.1.0 or contact support and ask for a single patch for this bug.

• 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.

• 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:

  This is where I get an error:
  var allPeople DB. People.ToList ();
  
  allPeople.ForEach (x = > Console.WriteLine ("type:" + x.GetType ()));
  
  }
  
  This will raise the following error when I extract in allPeople:
  
  
  All objects of the 'Entities.People' EntitySet must have unique primary keys. However, an instance of the type "TestingTPTInheritance.EMPLOYEE" and an instance of type 'TestingTPTInheritance.SUPERHERO', both have the same primary key value, ' EntitySet = people. ID = 38'.
  
  
  Looking at the database, everything seems fine

  -Employee table-
  ID JOBTITLE

  -Table of superheroes-
  SUPERPOWER ID

  C1 C2 C3 C4 NAME
  0X0X 40 Superman
  0X0X 39 John Doe regular programmer
  
  Is this a bug in ODAC. If even there is a work around or will there be a fix soon?
  
  Published by: Amplus on 7.11.2012 07:59

  Given our generated queries are slightly different (for example CASTs on the ID column and the order of the columns in the SELECT list).
  the result of the query should be logically even.
  I ran the query generated from you on my 11.1 database, and the result is below.

  C1 C2 C3 C4 NAME
  0X1X Superman flight 66
  0X0X 65 John Doe regular programmer

  You see the 'theft' is not absent from the line of "Superman."

  If you run the generated query me on your database Oracle Express 11.2 and 'Theft' is still missing, then we
  don't know there is difference between the two databases that we use.
  The error that you got may be linked to this difference. You can confirm by trying with other Oracle database
  other than an Express database.
  Be sure to replace "SCOTT" with "TRP" in the generated query 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
  Bill44077

  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.

• Is it possible to combine Entity Framework 6 with ODAC 11 g within Visual Studio 2015?

  The .NET application, I want to develop will be deployed on a server with the customer Oracle 11 g used to access a back-end 10g database.  I would use the possible latest technologies which can still fulfil this obligation.

  Is it possible, therefore, to combine Entity Framework 6 with ODAC 11 g (or develop using 12 c, but deploy to an application server running 11 g)?  Should I strictly use ODP.Net Oracle libraries to do this?  I'm hoping to use Visual Studio 2015 (about to be released).

  If this is not possible, what are my options?

  Only ODP.NET 12.1.0.2 in ODAC 12 c R3 and higher is certified with EF 6. You must use a client of 12 c. However, you can still access a 10.2 this customer DB server.

  Hi Torsten,

  Thanks for reporting the problem. I logged a bug.

  You can view together as "list of system types" directory to "preference > Data Modeler"-probably no longer exists. I guess that the setting for this directory is empty when you start SQL Dev as a different user.
