Creating classic report to the stored procedure.

How can we create a report based on a stored procedure out parameter.

Can someone please help.

Thank you

Nani.

Out parameter is a multi-level object type.

I found a way to sort of basis a report on the parameter OUT procedure. The approach is:

1. call the procedure in a process before PL/SQL areas, convert the object returned in an XML document and store in a collection XMLType column:

declare

  k_rate_query varchar2(255) := 'RATE_QUERY';

  l_rate_type_code  number;
  l_rate_query      rate_rec;
  l_xml             xmltype;

  l_seq_id number;

begin

  l_rate_type_code := to_number(:p1_rate_type_code);
  api_pkg.rate_query(l_rate_type_code, l_rate_query);
  l_xml := xmltype.createXML(l_rate_query);

  if not apex_collection.collection_exists(k_rate_query)
  then
    apex_collection.create_collection(k_rate_query);
  end if;

  select
      seq_id
  into
      l_seq_id
  from
      apex_collections
  where
      collection_name = k_rate_query
  and n001 = l_rate_type_code;

  apex_collection.update_member_attribute(k_rate_query, l_seq_id, 1, l_xml);

exception

  when no_data_found
  then
    apex_collection.add_member(
        p_collection_name => k_rate_query
      , p_n001 => l_rate_type_code
      , p_xmltype001 => l_xml);

end;

2. use a SQL/XML query on the XML collection in the region report source:

select
    rq.*
from
    apex_collections ac
  , xmltable(
        '/RATE_REC/RATE_TBL/RATE_REC_TYPE'
        passing ac.xmltype001
        columns
            action_code         varchar2(20)  path 'ACTION_CODE'
          , rate_key            number        path 'RATE_KEY'
          , rate_type_code      varchar2(5)   path 'RATE_TYPE_CODE'
          , program_key         varchar2(12)  path 'PROGRAM_KEY'
          , rate                number(8,5)   path 'RATE'
          , effective_date      date          path 'EFFECTIVE_DATE'
          , current_yn          varchar2(1)   path 'CURRENT_YN'
          , non_current_dt      date          path 'NON_CURRENT_DT'
          , non_current_by_id   varchar2(4)   path 'NON_CURRENT_BY_ID'
          , non_current_reason  varchar2(400) path 'NON_CURRENT_REASON') rq
where
    ac.collection_name = 'RATE_QUERY'
and ac.n001 = to_number(:p1_rate_type_code)

  • Block based on the stored procedure cannot modify Default_where clause

    Hi all

    I tried to create a block based on the stored procedure that it works very well with the result set for the refcursor. But if I need to add filters on the block using where clause in the palette of goods or

    using the property block set in where clause, it does not error but does not review filters .

    tried everything to you please let me know. This is a restriction whereby we can set filters on the block when we create the block based on the stored procedure.

    Thank you

    Check in Form Builder Help:

    Creating a block of data from a procedure that uses a ref cursor

    ... You can't pass a WHERE or ORDER BY clause clause in a stored procedure.

    But you can send your WHERE condition using the query Source Arguments.

    If the procedure is on the side of the database (not in the forms module), ensure that the procedure is not vulnerable to injection of SQL code.

    Hello

    Sorry for the inconvenience. After I posted this question I took a break and saw that the error was nothing, but I had given FNAME as parameter name in MS SQL. In oracle when I created the sp I created the parameter with p_FNAME. Where the schema defined in the language SSDL and CSDL, MSL had to be changed to MS, but since I want to that it would be same in different databases, I choose to have changed it in oracle stored procedure. The error msg is confusing, it should be something not found parameter or incompatibility etc.

  • Fall in the stored procedure option

    Hi Expert,

    I created the option in one of my stored procedure for testing purposes and now I am trying to drop the option and let the stored procedure, anyone know how I can do? Thank you!

    If what you want is to eliminate the Option that you have created in your Proc, you only need to:

    Expand the sign + to the left of you proc;

    Select the option that you want to remove;

    Press DELETE, or right-click and delete:

  • Materialized view, based on the stored procedure

    Hi all

    is it possible to create a materialized view on the results returned by a stored procedure?

    If this is not the case, do you think that any other way except for filling a table with data from the stored procedure and then founded the MV on it?

    Thanks in advance.

    MichaelTsilikidis wrote:

    Sorry I don't speak properly. In fact the procedure does not return a value, it fills one of its parameters (of the ref cursor type) of data. That's what I wanted.

    No it's not.

    REF CURSOR don't store data, so it's not possible.

    A Ref cursor is just a pointer to a query... and you can't "select from" a ref cursor, you can retrieve only one open.

    PL/SQL 101: Understand the Ref Cursor

    As correctly stated above, you can't question from a procedure to a function, and a materialized view is based on a query, you cannot use a procedure in a materialized view.

    You could use a function pipeline instead of a procedure, or have the pipeline function obtain the results of the procedure and pipelines, and then the materialized view could be based on the results of this function in the pipeline.

    example of function pipeline:

    Oracle manages two "flavors" of the stored procedure - copyright and rights of the Summoner. Rights of the DEFINER (default) is always performed under stored security area of the owner of the procedure no matter who calls it. So, if you ask USER_TABLES (or any display USER_, besides) within DEFINER rights stored procedure, you will get a list of tables owned by the owner of the stored procedure, not stored calling procedure. Rights (AUTHID CURRENT_USER) stored Invoker procedure is always carried out under the domain of the calller security. Therefore, if you are querying USER_TABLES (or any display USER_, besides) within the Summoner rights stored procedure you will get a list of tables belonging to the appellant a stored procedure. Hope it answers your question.

  • Can not see all the stored procedures in the Entity Data Model Wizard

    I hope it is a simple oversight on my part I try to use the new beta version of odp.net with entity framework support. I can open the Entity Data Model Wizard, give him my information database, and I can choose various tables to use successfully. But in the list where I select the tables, views and stored procedures, the wizard does not see my stored procs or my point of view.

    Does anyone know why he would see the tables but not views or stored procedures? My procs can be found under "packages" If that makes a difference. I tried to create a fictional stored procedure at the level above the title of 'procedures', but it is unclear whether.

    Is it possible for me to debug this from here? The log files, I could watch that would help me?

    Can you please let me know, what am I doing wrong and how can I pass an array to a procedure/function using java controls.

    Any help will be much appreciated.

    Try using an oracle.sql.ARRAY with a nested table or varray instead of a table index. Create the type SQL and Java object as follows

        SQL> create type sl_tab as varray(3) of integer;
        Java:
            ArrayDescriptor ad = ArrayDescriptor.createDescriptor
                (".SL_TAB", java.sql.Connection);
            Object elements = new Object[3];
            elements[0] = new Integer(12);
            elements[1] = new Integer(13);
            elements[2] = new Integer(14);
            oracle.sql.ARRAY array =
                new oracle.sql.ARRAY(ad, oracle.jdbc.OracleTypes.ARRAY, elements);
            SQLParameter[] params = new SQLParameter[1];
            params[0] =
                new SQLParameter(array, oracle.jdbc.OracleTypes.ARRAY, SQLParameter.IN);
            String succ = dbControl.testFunc(params);
    

    I don't think that you can pass an array of Java, this is why you have more success using an oracle.sql.ARRAY with a SQL varray. -Michael-

  • Run the stored procedure of c#

    Hi, im new to the use of stored procedures and I have the following stored procedure...

    CREATE OR REPLACE PROCEDURE DRL_PROCEDURE2 (var_SOURCE_OBJECTID IN varchar2, var_NEW_OBJECTID OUT varchar2)
    AS
    BEGIN
    SELECT MAX (NEW_OBJECTID)
    IN var_NEW_OBJECTID
    OF DRL_CONVERSION
    WHERE SOURCE_OBJECTID = var_SOURCE_OBJECTID;
    END;

    I want to be able to call this procedure from my windows form application and display the result of the stored procedure in a label... could someone please help me! Thanks in advance!

    http://www.csharpfriends.com/articles/getarticle.aspx?articleid=78
    You can find out how to call the stored procedure (in the link above you will find an example of SQL Server 2005 that also work for you from your oracle stored procedure) in c#.

  • How to call the stored procedure from javascript? (Google suggest, AJAX)

    Hi I want to set up a text field so that it behaves like [Google Suggest | http://www.google.com/webhp?complete=1 & hl = en].

    I read this post .

    Now, I installed everything according to this document. But it simply doesn't. And I don't know why.

    I think that problems can fall into the following three categories:
    1. the text field and the page invoking the appropriate javascript?
    2 - is the JavaScript call the stored procedure?
    3. the stored procedure correctly returns the result formatted?

    I'm assertive for 1 and 3, but I'm not sure 2. Because I don't know how if a stored procedure has been called? Is there a PL/SQL statement that I can query in SQL * more?

    Also, I would like to know how to debug AJAX in the APEX. It involves a lot of things.

    Finally, I used APEX 3.2 and Oracle XE. I can't find file dads.conf or marvel.conf. Is ' / apex / "the virtual directory for APEX?

    Thank you very much!

    Buffalo,

    I managed to make it work on XE with APEX 3.2!
    It took more time than expected because my XE installation was still on an earlier version of the Apex and I had put it first...

    But that's what I did:
    -in the ac.js file, I changed the path ' / apex / "and I added the ac.js file to my candidacy as a static file. So as you did.
    -J' copied my request to the XE and copied my procedure on the schema that is related to my request
    -J' gave to run anonymous rights my procedure

    Now at first, it did not work...
    Then I suddenly remembered something: If you want to run a procedure through the pl/sql gateway in the XE, XE please how it is.
    Do you this by changing the APEX_030200.wwv_flow_epg_include_mod_local function!

    This is the code for the function changed for my example:

    CREATE OR REPLACE function APEX_030200.wwv_flow_epg_include_mod_local(
        procedure_name in varchar2)
    return boolean
    is
    begin
        --return false; -- remove this statement when you modify this function
        --
        -- Administrator note: the procedure_name input parameter may be in the format:
        --
        --    procedure
        --    schema.procedure
        --    package.procedure
        --    schema.package.procedure
        --
        -- If the expected input parameter is a procedure name only, the IN list code shown below
        -- can be modified to itemize the expected procedure names. Otherwise you must parse the
        -- procedure_name parameter and replace the simple code below with code that will evaluate
        -- all of the cases listed above.
        --
        if upper(procedure_name) in (
              'MATTHIASH.INCSEARCH') then
            return TRUE;
        else
            return FALSE;
        end if;
    end wwv_flow_epg_include_mod_local;
    /
    

    After that, the AJAX function worked as expected...
