• Cannot use the native sequence of database to insert data through the DbAdapter

  Hello

  I use Oracle Fusion Middleware 12.1.3 (selection of pre-designed developer programs for Oracle VM VirtualBox VMs |) Oracle Technology Network). I'm trying to insert data into the Oracle database coming with the device via a DbAdapter. I want to use the native Oracle sequences for primary keys and have configured appropriatelly the DbAdapter. But in execution, I get the following exception:

  Caused by: java.sql.SQLIntegrityConstraintViolationException: ORA-01400: cannot insert NULL into ('SCOTT'. "ORDERS '." (' ' ID ')

  If I configure the such DbAdapter that do not use sequences, I get the same exception. I'm missing here?

  Kind regards

  Nicolas

  Reading more carefully the exception, in the log file of the server, not just the display of messages in the console of the em, I could note that the ConnectionFactory configured on the outgoing Dbadapter connection used to access the database was incorrect. He was using JavaDb instead of Oracle that I made a mistake of copying and pasting. Correction of this error has resolved the problem.

• retrieve the view of a database link definition

  Hi people,
  
  I can able to describe the view from the DB using link below

  'm here get the structure which is fine, but I want to see the definition of the view of v_emp which is in the schema 'abc '.
  
  Using below, I can retrieve my local point of view, here my question is how can I recover the 'abc' DB link?

  select dbms_metadata.get_ddl('VIEW','V_EMP') from dual;

  Please help me
  
  Thank you

  Using below, I can retrieve my local point of view, here my question is how can I recover the 'abc' DB link?

  select dbms_metadata.get_ddl('VIEW','V_EMP') from dual;
  

  You can't get the ddl of the remote object. But you can use data dictionary views remote, for example dba_views@link.

  Another way is to write a procedure remote DB that gets the ddl of the local object, so you can call it via dblink.

• No access to the data in a database linked when calling procedures in the APEX 5

  Hello

  I use

  • APEX 5.0.3

  • DB related: Oracle DB 11 g

  When you call procedures and packages of APEX-side on the related DB, I can't access the data with a "select...". "in the tables on the DB related.

  Is it because of the different versions of DB?

  Is there a general setting in my APEX 5.0.3 I need to access the data in the tables on the DB related?

  Any help appreciated.

• the variable name of database query to SQL Server using the Oracle database link

  Hi all
  
  I have an ApEx 4.1 application running on x 64 (11.2.0.1) 11g on Windows Server 2008 x 64, and I have a few points of data integration with SQL (2005 and 2008) server that I need to create. I have configured the database with dg4odbc link and it works perfectly... I can run queries on the SQL Server database without any problem using the database link.
  
  However, there is a scenario where the SQL Server database name is dynamic, and I need to generate on the fly in a PL/SQL block and then use it in a query dynamic SQL (all this in the ApEx). It of wherever I meet problems... when I asked the default database that is based on the ODBC connection and I don't have to specify the name of the database, no problem. But when I need access to one of the several other databases by default, I received the error "invalid table.
  
  It works well:* (note that 'fv' is the name of my database link)
  
  v_query1: = "select 'Release Date' from dbo." Schedules@FV where dbo. Annexes. "" SchedID "=: calendar";
  EXECUTE IMMEDIATE v_query1 in rel_date using the grid.
  
  
  
  
  I then take this rel_date variable, convert a varchar2 (rel_date_char), then use it as the name of the database in the following query...
  
  
  _ It returns an error(error ORA-00903: invalid table name)
  
  v_query2: = "select"PARTNO": rel_date_char.dbo.ProdDetails@fv where 'SchedID' =: calendar and"UnitID"=: unit"
  and 'MasterKey' =: master and "ParentKey" =: parent';
  
  EXECUTE IMMEDIATE v_query2 in part_number using planning, master, parent unit;
  
  
  
  I also tried using all of the following conditions without result:
  
  "select"PARTNO"of" | : rel_date_char | '.dbo. ProdDetails@fv where 'SchedID '...
  "select"PARTNO"of" | rel_date_char | '.dbo. ProdDetails@fv where 'SchedID '...
  "select"PARTNO"of" | @rel_date_char | '.dbo. ProdDetails@fv where 'SchedID '...
  "select"PARTNO"in @rel_date_char.dbo.ProdDetails @fv where 'SchedID'..."
  
  
  Is it possible to do it in PL/SQL?
  
  Thanks for any help!

  => instead of executing the statement using the "execute Immediate" we use the PASTHROUGH package to pass the statement to SQL Server.

  Hello

  I would do something like the code:

  BEGIN
   DECLARE
    vDATE DATE;
   BEGIN
    vDATE := TO_DATE(:P1_DATE1,'DD.MM.YYYY');
    WHILE vDATE <= TO_DATE(:P1_DATE2,'DD.MM.YYYY')
    LOOP
      INSERT INTO ABC (DTE, LEAVE)
      VALUES (vDATE, :P1_C);
      vDATE := vDATE + 1;
    END LOOP;
   END;
  END;
  

  You must ensure that the datepicker points both use the ' JJ. MM YYYY ' date format.

• ONLY INSERT OR DELETE THE PRIVILEGE TO THE DATABASE LINK

  Hi all

  Version of DB 11.2.0.1

  RedHat 5.5 operating system

  I created a link to private database by following the path

  create database link test_link

  connect to Scott identified by tiger

  using

  '(DESCRIPTION =)

  (ADDRESS = (PROTOCOL = TCP) (HOST = 10.194.180.45)(PORT = 1521))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = prod)

  )

  )'

  The link is created successfully and I am able to perform all the DML operations on it.

  The Question is there a way by which we can give only insert or delete or privilege is not to remove from the table at this link.

  For operations select only, I know that by creating a view I can restrict the remote user, but is there a way by which I can give only insert or remove remove link of database.

  You can not grant any privilege to a link. Can you and your team identify a location in the documentation, if required?

  By default, a remote session will get the same privilege as the user to which it connects.

  BTW:

  • do not use a database link tnsnames.ora makes your hard to maintain link
  • using addresses IP hard in a database link makes your link even more difficult to maintain
  • by specifying a hardcoded password in a database link is a breach of security.

• Database link - what ports are used?

  I'm trying to create a link of database from a very locked down server (A database) at database B, which is on my internal network.

  Hello

  Try this in your source and XEPROD it is your right to target db

    sqlplus user/pass@XEPROD
  

  When you create a db-link use any connection string and also how is your configured sqlnet.ora you may need to use. WORLD in the name of link

   CREATE DATABASE LINK "LINK_NAME"
   CONNECT TO USERNAME
   IDENTIFIED BY "password"
   USING '(DESCRIPTION =(ADDRESS_LIST =
