How to execute a stored procedure that returns a cursor?

• Calling an Oracle stored procedure that returns a REF cursor

  Hi guys,.
  
  I'm calling an Oracle stored procedure that returns a REF CURSOR. Here is the piece of code that I'm working on:
  
  procedure TC307_MAIN (p_program varchar2, varchar2, varchar2, result_set OUT eng_cur p_engchgno p_project) as
  Start
  IF (p_program = 'Navybased' and p_project = 'PROTECTOR-BUILD') THEN
  result_set: = comments. Tc307_Eng_Chg_Rpt.TC307_RNZN (p_engchgno, result_set = >);
  END IF;
  end TC307_MAIN;
  
  procedure TC307_RNZN (p_engchgno varchar2, result_set IN OUT eng_cur) as
  Start
  end TC307_RNZN;
  
  PL/SQL code behind TC307_RNZN is big enough, that's why I've not stuck here. Basically, the second stored procedure executes a PLSQL statement and returns a result set. I need to return the result_set in the main proceedings based on nested else statement which I am still trying to build. I get a compilation... error can someone guide me with the correct method to call the second stored procedure and returning in the main proceedings.
  
  Thank you very much.

  Rohan,

  Try this

  procedure TC307_MAIN(p_program  varchar2,
                         p_project  varchar2,
                         p_engchgno varchar2,
                         result_set OUT eng_cur) as
    begin
         IF (p_program = 'RNZN' and p_project = 'PROTECTOR-BUILD') THEN
                -- This is a procedure not a function
                       guest.Tc307_Eng_Chg_Rpt.TC307_RNZN(p_engchgno, result_set); --UR compilation error on this line*
        END IF;
    end TC307_MAIN;

  We have accessed Sybase 15 with SQL developer.

  We can see the data in the table, if we do not, run the stored procedure (for instance sp_who) developed on Sybase.

  Could you tell me how we execute the stored procedure on Sybase with SQL Developer Sybase?

  Thank you

• How to call a stored procedure with a REF CURSOR output parameter

  I'm looking forward to example calling a function/stored procedure with a REF CURSOR output parameter and get the result.
  In other words, I have a stored function/procedure that runs a SELECT statement using the OCI library and then he could get the values of each row and each column.
  
  I put a code snippet, it have only the main thing to call a simple stored procedure and to print the name of each column of the cursor, but I couldn t to print out values in the table that calls the stored procedure.
  I understand that the next step is to call an OCIStmtFetch.
  How to associate the slider with the OCIStmtFetch?
  
  If you need more information, just tell me.
  
  I use ANSI C with HP - UX (HP - UX C) operating system and Oracle 10 g.
  
  
  Kind regards.

  Hi Antonio,.

  I see this:

  c_buf=(ub1 **)calloc(sizeof(ub1 *),3);
  
  ...
  
  rc=OCIDefineByPos(pOciStatCursor,&pdef,(OCIError *)pOciError,pos,c_buf[pos-1],size+1,(ub2)type,(dvoid *)c_indp[pos-1],(ub2 *)0,(ub2 *)0,OCI_DEFAULT);
  

  That I don't understand. You allocate space for 3 pointers ub1 but I don't see where these pointers are then initialized to point to where the data is to be stored.

  I do not read correctly?

  Sorry for posting code long, but here is an example of code that I have. It is much more 'code' for your code, but maybe that will be enough...

  NOTE: This is just the code example and not rigorous. For example, I don't check the memory, allocations etc in this code!

  Kind regards

• Calling a procedure that returns a cursor in a procedure

  Hello
  I have two stored procedures. They both return a cursor as output variables. However, I have another stored procedure that calls these procedures and return their results once again an output variable. I know that sounds strange to want to do something like this, but how can I do this?

  Mikhail says:

  My first procedure returns a cursor. But the cursor is opened on one condition. Like, if PARAM1 = 1 THEN OPEN cursor_1 to SELECT... OTHERWISE, OPEN CURSOR_1 TO SELECT... And the second slider has the same structure. The thing is in the two procedures if I declare that a single CURSOR_1 IN OUT parameter that the procedure will not work. So in both entities, I have two variables IN OUT SYS_REFCURSOR: c1 and c2. Then, in the third procedure I first call the first procedure, then the second. How can I write my third procedure in order to obtain the result two procedures United?

  Why the appellant (3rd procedure) need to have 2 ref Cursor? How will the appellant to "unite" the sliders?

  The actual data, a power of work must be done inside sliders. Not in PL/SQL or other languages. The SQL language is a very powerful and flexible language.

  So if the SQL 2 data sets (or more) must be "United", then you should not use the 3rd procedure and PL/SQL code to do. Should use you 2 sliders.

  You should watch this by using SQL only. The 2 sets of data can be merged, joined, union'ed. You can determine the intersection. You can determine the difference (with a negative sign). It can be rotated. It can be aggregated. It can be cube' ed. Etc.

  This SQL will then be used as a single slider and a unique reference cursor handle will be used to consume the output of the cursor.

  The basic rule to develop Oracle applications is simple. Optimize SQL. Minimize the PL/SQL.

  Use the SQL language to the data of the crisis. No PL/SQL.

  Hello

  How can I force DAC to run always full load for one of the task that executes the stored procedure? And remaining tasks load incremental in the second and sub sequent executions.

  Thank you

  Jay.

  Hi if your task is running an informatica mapping you can set your DAC task to run the full mapping for incremental and full loads, so tab task just point to the mapping.

  Hope that helps.

• How to create a stored procedure to delete and create table

  Version: Oracle 10g
  
  I am trying to create a stored procedure that is delete it and create a table based on a select statement. I can create the table, but I can't let it go.
  
  CREATE or REPLACE procedure EC_LOAD is

  user610131 wrote:

  If you drop off where you insert it :)? Do you mean DELETE or TRUNCATE?

  If table can be truncated (and don't forget TRUNCATE is DDL then he will commit):

  CREATE OR REPLACE procedure EC_LOAD is
  begin
  EXECUTE IMMEDIATE 'TRUNCATE TABLE Sales_table';
  INSERT INTO Sales_table
  (FSCL_WK,
  DIV,
  ACCT_TYPE)
  Select
  FSCL_WK,
  DIV,
  ACCT_TYPE
  from
  sales_revenue;
  end ecload;
  

  Otherwise, use DELETE:

  CREATE OR REPLACE procedure EC_LOAD is
  begin
  DELETE Sales_table;
  INSERT INTO Sales_table
  (FSCL_WK,
  DIV,
  ACCT_TYPE)
  Select
  FSCL_WK,
  DIV,
  ACCT_TYPE
  from
  sales_revenue;
  end ecload;

• 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...

• Call a procedure that returns a refcursor, use it in an another proc sql?

  I have a procedure that returns a refcursor; How can I include this refcursor in a sql statement that is inside another procedure, or view etc.?
  
  This is the kind of foolery, I tried so far (myproc1 returns a ref cursor):
  
  create or replace procedure myproc2
  (
  slider ref RC
  )
  AS
  RC1 of ref cursor;
  Start
  EXECUTE myproc1 (rc1).
  Open rc for
  Select rc1.* in the rc1;
  end myproc2;

  If you want to use the result set in an SQL Ref Cursor won't be of any help. Can be read all nested Table Type. You can declare an object type and store your result in them and use them in SQL.

  Thank you

• How to call a stored procedure in ADF

  How to call a stored procedure in the ADF (Jdev 11.1.1.6)?

• Simple question-how to call a stored procedure or function of apex?

  Simple question-how to call a stored procedure or function of apex?
  Thanks advance.
  Doug

  Hi Doug,.
  You can call a procedure or function of apex. It depends on what you want to do with the function or procedure. If you want to retrieve table data in a specific area, you can try something like this-

  The following statement creates the function get_bal on the oe.orders of sample table (PL/SQL is in italics):

  CREATE FUNCTION get_bal (acc_no in NUMBER)
  RETURN NUMBER
  IS acc_bal NUMBER (11.2);
  BEGIN
  SELECT order_total
  IN acc_bal
  Orders
  WHERE customer_id = acc_no;
  Return (acc_bal);
  END;
  /

  The function created in the previous example can be used in a SQL statement. For example:

  SELECT get_bal (165) FROM DUAL;

  GET_BAL (165)
  ------------
  2519

  hope this will help,

  Kind regards

• How to call a stored procedure PL/SQL of the Disqualification?

  I figured I could do this from a Groovy script but I am unable to make it work.

  Let's take the simplest scenario:

  At the end of a job, I have a need to call an once stored procedure that has no arguments.

  Translated by the logic of the stored procedure with Disqualification is not an option.

  If you must call it once at the end of a task, you must use the external task.

  If you call a procedure for each record, it can be done using a script.
