• PL/SQL API to set the text for the notification

  Hello
  
  Anyone can indicate APEX PL/SQL API to set the value of notification page text?
  
  I found call WWV_FLOW.show_error_message which display the error message, but doesn't seem that she also transaction Rollback - so I need to have something similar for notifications. Directly manipulate WWV_FLOW.g_notification works not as well - I had invalid checksum error.
  
  Any ideas will be appreciated.
  
  Sincerely
  Husbands

  Sentinel page is too early in the treatment of set this global but you should be able to use before header process, or at any other point in shooting to set. What is an API, it is not a because a simple assignment to the global level will be sufficient.

• create the SQL server programmatially data source

  Hello

  I would like to create a SQL server by programming in LabVIEW data source. The SQL server version that I used is from 2005. Can someone give some ideas? An example of code will be more favorable.

  Thank you

  You can build the connection string you even.  The open function in the Toolbox of data base accepts a string as well (it's polymorphic) who can be the connection string.  This is the site I use to understand.  Is the most common things.  You may need to search Google more specific elements.

  http://www.ConnectionStrings.com/

  If you want to use the other option, someone has achieved a UDL editor in LabVIEW.  You can use this code to create your own UDL which can use the Open DB function:

  I have used the above code, so can't comment on that.

• How to get the schema of the APEX by username in PL/SQL?

  Hey, guys:
  
  I have to write a PL/SQL procedure, which can become the apex (schema of the user) user group that we have defined by their Summit. I know I can get user account in reference to v (app_user), but I'm not familiar with the APEX API security management. is there a method to get the user APEX scheme providing the username as a parameter?
  
  Thank you.

• V8: Adding the extension to a data request created via the API

  Infra Enterprise version: 8.0.34.0

  Version of database: Oracle 9i 9.2.0.6.0

  I create a web application that registers a specific request through the RequestCreate API function. Unfortunately it doesn't seem to be any support to add data to the extension fields created from application designer. I thought to add data manually by using an insert statement. Is the Ref table su_extension_data field an auto-increment field or do I need get the max (ref), add 1, use either the ref to new records? It seems that, based on the infra_queries.sql file, I provide the ref for the extension data.

  All this seems to be a recipe for disaster. Is there a better way to add extension information to a request?

  Thank you

  All references are managed by the SU_NUMBER_ALLOC table. The NUMBER_ALLOC column is the next value to be used for the table defined in the column TABLE_ALLOC. If the value should be incremented or as kentyrr suggested to use the procedure stored in the ALLOCATEUNIQUEREF.

  You need to expand the stored procedure / SQL custom that will insert the extension using ALLOCATEUNIQUEREF fields and call using the function API ExecuteQuery. If you insert multiple extension fields, you can use the nQuantity parameter in order to book a bunch of refs for your instructions insert only once.

• APEX how to create an apex_collection

  Hello
  
  I currently work in a 'Survey' application and I want to store data and at the end to submit them.
  I read some topics and oracle bind on apex_collection, but I have the problem to the implementation, I don't know where and how to start:
  1. I have a page containing:
  A. report brings me data from a database. (these are questions)
  B. 1 point with 5 values (radio button) different types of responses
  I want to accomplish is to answer all questions and save all the answers at the end of DB. For this I thought to use the apex_collection to collect the information and after will see :).
  
  Can someone tell me how to create a collection (it's a process?) and How to store the responses ?
  

  Select a.question_num ||'.',
         b.text
  from xxgrp.xxgrp_hr_survey_dtl_360 b,
       xxgrp.xxgrp_hr_survey_dtl a
  where a.question_id = b.question_id  

  Thank you

  Indeed, the collection is a process.

  I'm still waiting in my business logic where the best place is to create. You say you have need some kind off investigation app.

  In this case, I would create when you open the first page off your App survey know that you can create it only once. If there is already let them down but in the API, there are procedures like create or truncate the collection.

  Everything you use in the API are procedures of the apex.

• To access the tips of existing PL/SQL API

  Hi all in the JDev/ADF community,
  
  I am a beginner in ADF coming from a form and background of PL/SQL. Using JDeveloper 11.1.1.2, I lived quite a few examples and read a lot of different guides developers. I'm happy with the basics of the model controller architecture and display when simply based on database tables. For example, I can create a fairly complex page with tabs, master relationships / detail, editing etc.
  
  The app I am writing to you in the end is to sit on top of an existing PL/SQL packages that provide most of the data and logic that surround it.
  
  So, to finally get to my question... I wonder what is the best way to approach using aspects of the API of PL/SQL in British Colombia ADF? I saw some things in the background documentation around the use of an API of simple table with procedures for insert/update/delete, however I cannot find directions on how to access the data returned in associative arrays. For example, there is a procedure that is called with a particular key value (will be passed as a parameter to the page) which returns then several tables of different records PL/SQL (for example, the OUT parameters). I need to access this information during a session of the app, so I think I need somehow to load it into an entity or view object. Y at - it an interface to access the record types and table PL/SQL in this way?
  
  Obviously, I want to reuse as much of the existing infrastructure, as I can, but if there are areas where this would result in unnecessary complexity on the side of the ADF, I'd consider reworking of these parts.
  
  I'm not a complete solution at this stage - just a few pointers on what direction to look would be much appreciated.
  
  Thank you very much
  
  Kevin.

  I would like to just one part of your question, given that Frank has indicated you in the General documentation to call PL/SQL from ADF business components address.

  You asked specifically about the transmission of arrays and associative arrays to and from PL/SQL procedures. These are artifacts of PL/SQL that do not interact with the outside environment. The main problem is that the modules developed in Java and other languages cannot easily discover the metadata for these tables. You'll need to translate into objects Oracle you set with the CREATE TYPE command. Here is one of my favorites:

  CREATE TYPE vc_arraytype AS TABLE OF VARCHAR2(4000);
  

  Then you declare objects of this type, and given that plug-ins can ask the database 'what is a VC_ARRAYTYPE?', they can use these objects. You would change your PL/SQL so that it uses tables from database nested as it instead of collections of native PL/SQL, or create procedures of wrapper which translate the tables of database embedded in the forms required by your initial proceedings, call the initial procedures, can translate the results if necessary.

  Associative arrays with non-integer index are a particular problem, because there is no equivalent type that you can create with CREATE TYPE. You can use a pair of nested tables, one for the clues and one for values, or create a record type such as

  CREATE TYPE assoc_rectype AS OBJECT(name VARCHAR2(30), val VARCHAR2(4000));
  

  Then a table nested in these folders:

  CREATE TYPE assoc_arraytype AS TABLE OF assoc_rectype;
  

• <>- Web Services <>- PL/SQL API UI

  Hi all
  
  We have inherited an existing application that has this architecture:
  UI - c# (WinForms, not web-based), completely independent of the DB
  WS - Web services, c#
  DB - Oracle 10g, > 500 paintings
  API - PL/SQL
  
  Because the user interface is blind DB, some information (parameters) can be sent backwards and this forces highly customized WS (from thousands of them; so, low probability of being in the future by other applications). In addition, each custom WS calls a custom MS.
  What I would do is, if is not allowed to use generic WS, at least to be able to write generic SP (PL/SQL).
  
  Here's a simple example:
  say a user enter 5 fields in a user interface. These channels are sent on the reverse, as input. We know what table and columns 5 channels, but only in the WS (not in the user interface). So upside I can build:
  INSERT INTO tableName (c1,..., c5) VALUES (v1,..., v5)
  and then call a GSP that will simply run the SQL statement.
  
  The problem here is that some other applications would like to insert other attributes of a column in the table, and I don't want to write of cSP for, say, 2 fields or 6, etc.. Instead, an SP must be written.
  
  Any ideas?
  Thank you very much.

  How much effort do you spend trying to work around something that is architecturally incorrect? Fixing it is not possible, because it will need a complete rewrite. So where you draw the line and cut your losses?

  The answer is sooner rather than later. I know a couple of systems where these issues were known and ignored - and put on hold to address at a later stage. In the meantime the monster grows in size, and it becomes more and more difficult (and much more expensive) to solve the basic problems. And then 8 + years pass and you are so deep in that flawed architecture, there is almost no loophole that is not custom, you and the business. And a lot of trouble.

  Like cancer... the best treatment for imperfect architecture is early treatment.

  I would stop all development on this architecture. Provide for basic maintenance only. Identify the basic elements required by the user base. To implement these on APEX as soon as possible. This will allow to spend the rest of the system through to APEX to a more structured and better controlled method in treating back problems (such as data modeling, design and implementation physical db) too much respite.

• Essbase Administration Service - create rules SQL file - connection error

  Hello

  I am creating the rules SQL files in Essbase Administration Console.

  When I press the OK/recover button in open SQL data source window I get this error:

  cannot connect to establish a connection with the SQL Server database see log for more information

  I tried the ODBC connections and BEAK .

  When I test the ODBC connection in Windows administrative tools > Data Sources (ODBC) > system DSN, it works correctly. but in open SQL error there.

  I tried two separate databases for my test.

  an Essbase server machine.

  a separate server.

  both give me the same error.

  SRD: 11g R2

  Essbase: 11.1.2

  

  Do you have any suggestions?

  Create the DSN using DataDirect Oracle Wire Protocol 7.0 in (System DSN) ODBC administrators and test the connection of the Rules file. It will work.

• Can SQL gurus, you create a SQL to do this?

  I have a query that brings together the records of 2 columns:

  ROOM_DESC Detail_count

  Not reserved - clean, 4

  Not reserved - salty, 30

  Reserved - clean, 8

  Reserved - salty, 47

  Is what I want, without creating a temporary table, use the SQL existing as an input and output it:

  Rooms, 89

  Clean, 12

  Dirty, 77

  Even if getting to the rooms is not technically possible, to get the other 2 total records would be great.

  Hello

  This looks like a job for the REPORT GROUP.

  Here's one way:

  WITH original_query AS

  (

  SELECT...  AS room_desc

  ,        ...  AS detail_count

  ...

  )

  got_room_grp AS

  (

  SELECT SUBSTR (room_desc
  , INSTR (room_desc, "-") + 3
  ) AS room_grp

  detail_count

  Of original_query

  )

  SELECT NVL (room_grp, 'Rooms') AS grp_label

  SUM (detail_count) AS detail_count

  OF got_room_grp

  GROUP OF ROLLUP (room_grp)

  ORDER BY NULLS FIRST room_grp

  ;

  According to what did you do in the original request, there might be a much simpler way.  Chances are, you can derive from room_grp without devoting a separate subquery, as I did above.  You might be able to do all the work without any subqueries in all.

  If you would care to post CREATE TABLE and INSERT instructions for sample data and your needs, then I could test it and maybe show you a simpler and more efficient way.

  The query above assumes that room_desc always contains "-", followed by another text.  If this isn't the case, then you need a slightly more complicated expression for grp_label in the main query:

  ...

  SELECT THE CHECK BOX

  WHEN you GROUP (room_grp) = 0

  THEN room_grp

  ELSE 'rooms '.

  END AS grp_label

  ...

  or perhaps other slight modifications, but the general approach here show will still work.

• Error ora-02019 in PL/SQL call in the apex, but not in a SQL Client

  Hello

  I encountered a strange problem. I have a process page type PL/SQL that runs on submit a form.

  This process calls a PL/SQL package function.

  When I run the PL/SQL Code from a SQL, for example SQL Navigator Client it works without problems.

  When trying to run from the APEX, it is always fails with the error:

  ORA-02019: description of the connection to the remote database not found

  It's the SAME code in both situations.

  It's the process code:

  DECLARE

  v_result INTEGER. v_result_msg VARCHAR2 (4000);

  v_ref_date DATE; v_reset INTEGER.

  BEGIN

  -Prepare the arguments

  v_ref_date: = TO_DATE (: P73_REFERENCE_DATE, ' DD/MM/YYYY');

  v_reset: =: P73_RESET;

  -Use the feature

  TRC.trc_jobs.xade_daily_job (v_ref_date, v_reset, v_result, v_result_msg);

  END;

  When I debug Apex I trace to the bottom of the error, in a job that makes a join with a table in a database link.

  It is the offending function:

  FUNCTION (p_series_name IN VARCHAR2, p_date AS get_series_cfi_code,

  p_date_active_flag in FULL)

  RETURN VARCHAR2

  IS

  v_cfi_code instrument_type.full_cfi_code@dl_herds%TYPE;

  CURSOR c_get_series_cfi_code IS

  SELECT it.full_cfi_code

  I, instrument_type@dl_herds INSTRUMENTS it

  WHERE i.series_name = p_series_name

  AND ((i.expiration_date = p_date AND p_date_active_flag = 0) OR)

  (i.expiration_date > = p_date AND p_date_active_flag = 1))

  AND i.product_id2 = it.id

  ORDER BY i.expiration_date;

  BEGIN

  OPEN c_get_series_cfi_code.

  SEEK c_get_series_cfi_code INTO v_cfi_code;

  CLOSE C_get_series_cfi_code;

  RETURN v_cfi_code;

  END get_series_cfi_code;

  No idea why this is happening?

  I think to reproduce the table locally to eliminate the use of dblink as a last resort.

  • The property Websheet 'allow SQL and PL/SQL' is set to Yes
  • The feature Instance "activate SQL and PL/SQL Access in Websheets" is set to Yes (and the new application websheet was created after I had set it to Yes)

  I have also enabled these settings back to ensure that they were properly stored.

  Is there another switch, that I forgot?

  Thanks for your ideas,

  Hi Andreas,

  This is deliberate. We had to remove the ability to create new areas of PL/SQL in Websheets in 4.2.2 because of security concerns during an internal audit function (the function has been questioned, not the implementation). It has been listed as bug 16536609 (Deprecate support of the section of PL/SQL Websheets) in known issues, but no doubt he deserved a more visible documentation.
