• PL/SQL - Call Out Ref Cursor returned by a stored procedure

  Hello

  I am creating a procedure where a Ref Cursor is defined as an OUT parameter, my question is how to shout that the Ref Cursor when I run for example here is how I want to call my EXEC sql command:

  EXEC film_not_in_stock (2,2,vcur);

  Here is the procedure:

  CREATE OR REPLACE PROCEDURE film_not_in_stock (p_film_id in NUMBER, p_store_id number, vcur ON SYS_REFCURSOR)

  IS

  News sys_refcursor;

  v_cur inventory.inventory_id%TYPE--ou is the same type of column inventory_id

  v_cur sys_refcursor;

  BEGIN

  Heart OPEN to SELECT inventory_id

  INVENTORY

  WHERE film_id = p_film_id

  AND store_id = p_store_id

  AND inventory_id NOT IN (SELECT inventory_in_stock (inventory_id) FROM dual);

  News of FETCH in v_cur;

  OUTPUT WHEN heart % NOTFOUND;

  END;

  /

  I know there are typos in the procedure, you will appreciate if you can help me to put it right.

  Thank you very much!

  Tonya.

  In fact, based on your previous post, function inventory_in_stock returns 0 or 1. If so, there are:

  CREATE OR REPLACE

  PROCEDURE film_not_in_stock)

  p_film_id in NUMBERS

  p_store_id in NUMBERS

  p_cur ON SYS_REFCURSOR

  )

  IS

  News sys_refcursor;

  v_cur inventory.inventory_id%TYPE--ou is the same type of column inventory_id

  v_cur sys_refcursor;

  BEGIN

  OPEN p_cur

  FOR

  SELECT inventory_id

  INVENTORY

  WHERE film_id = p_film_id

  AND store_id = p_store_id

  AND inventory_in_stock (inventory_id) = 0;

  News of FETCH in v_cur;

  OUTPUT WHEN heart % NOTFOUND;

  END;

• How to perform procedures with REF CURSOR & PLSQL settings table in SQL Dev?

  I have 3 SQL Developer. I create a procedure with a set of tables/PL/SQL as an input parameter and a SYS_REFCURSOR as output parameter.
  
  When I press the green arrow (Run button) block the dialog box run PL/SQL PL/SQL has no place at the PL/SQL table with records of entry and also to see the output of the SYS_REFCURSOR.
  
  I get the error ORA-06550 and many other errors when I run the present.
  
  How to do this please?

  In the debug code, lose the ABS. Prefix the SYS_REFCURSOR QC_SQL_DEVELOPER_TEST.
  Also, do not use same name of your settings on your bind variable (so e.g.: OUT_REF_CURSOR).
  REF CURSOR is supported output types, so you will get the output of their share in the output tab.
  However the output system does not recognize your own types as your PL/SQL table. You need to write an exit procedure yourself, indexing correctly, using the DBMS_OUTPUT.

• Error when you work with Ref Cursor

  Hi, I tried the following, but the err

  DECLARE
   TYPE ref_nm IS REF CURSOR;
   vref REF_NM;
   vemp emp%rowtype;
  BEGIN
   OPEN vref FOR SELECT ename ,sal FROM EMP;
   LOOP
    FETCH vref INTO vemp;
    EXIT WHEN vref%NOTFOUND;
      DBMS_OUTPUT.PUT_LINE ( vemp.ename ||','||vemp.sal ); 
   END LOOP;
    CLOSE vref;
  END;

  Error is
  

  ORA-06504: PL/SQL: Return types of Result Set variables or query do not match 

  Use you this structure as a buffer of extraction:
  PEMV emp % rowtype;

  This structure contains the whole line of EMP - all columns.

  That's what you're looking for cursor - 2 columns (not the whole line):
  Vref OPEN for SELECT ename, sal of EMP;

  You can not expect from PL/SQL to find out how to move the 2 column values in a structure that has more than just 2 columns. The error message is quite clear about this - read and think what is transport of the error.

  But confused how to have Ref Cursor
  Could you help me in this...
  
  Thank you

  You must declare a variable of type T_CURSOR and pass it to the procedure like this.

  declare
    lOutCursor CURSPKG.T_CURSOR;
  begin
    CURSPKG.OPEN_ONE_CURSOR(, lOutCursor);
  end;
  

• NamedStoredProcedure with Ref Cursor output

  I would like to install a NamedStoredProcedureQuery who can receive results of a cursor, and I wonder if it's possible.
  
  So I have my procedure:
  
  procedure test_proc (t_cursor ON ref_cursor)
  is
  Start
  Open the t_cursor for
  Select * from enrolment;
  end;
  
  and my NamedStoredProcedureQuery:
  
  @NamedStoredProcedureQuery (name = "TEST_REF_CURSOR", procedurename = "TEST_REF_CURSOR.test_proc", returnsResultSet = true,
  parameters = {@StoredProcedureParameter (queryParameter = "t_cursor", name = "t_cursor", direction = Direction.OUT_CURSOR, type = Enrolment.class)})
  
  
  So I try to call my Proc with:
  
  Query query = em.createNamedQuery ("TEST_REF_CURSOR");
  List results = query.getResultList ();
  
  and I get a oh so helpful error:
  
  
  Inner exception: java.sql.SQLException: ORA-00900: invalid SQL statement
  
  Error code: 0
  Call: BEGIN TEST_REF_CURSOR.test_proc (t_cursor = >?); END;
  link = > [= > t_cursor]
  
  
  I'm doing something wrong or should I use StoredProcedureCall instead?

  It should work.

  The question seems to be

  returnsResultSet = true,

  delete it, or set it to false.

• How to start the view off of the ref cursor Oracle as input/output param

  Hello world

  We use JDev 11.1.2.3 WL 10.3.6 and Java 7.

  We are at the beginning of our transition from Oracle Forms to ADF.  We have a very large forms that uses many store procedures that have IN/OUT ref Cursor parameters and tables plsql.  I tried to find information on best practices to achieve, but only seemed to find tutorials on SEO of the Oracle ref Cursor return functions.  I hope we don't have to rewrite our code of database to work with ADF.

  This is an example of a proc currently a block on a form based on directly

  The ref cursor parameter is input/output to satisfy the way the form handles this type of paradigm.

  ADF we want I hope to reuse these procs existing (without the need to wrap/overload them) on the basis of the display objects.

  Example:

  / * my record type which houses the information I want to go back * /.

  TYPE rec_hist_vacpac_status IS RECORD)

  rec_order NUMBER (5),

  rec_rownum NUMBER (5),

  return_column SAM_VACPAC.vacpac_status%TYPE,

  rec_login_id SAM_VACPAC.ins_user%TYPE,

  status_date SAM_VACPAC.status_date%TYPE

  );

  / * Sets the ref cursor type * /.

  TYPE lcur_hist_vacpac_status IS REF CURSOR;

  / * This is a procedure that would take some info link go / return

  Return the ref cursor of this information as an in / out * /.

  PROCEDURE prc_myinfo_refcur)

  pnum_identify_seq_id in NUMBERS

  pcur_myinfo IN OUT lcur_hist_vacpac_status);

  Can anyone point me in the right direction on documentation on this?

  Thank you!

  Hi Cemerson:

  );

  1. 2. create a TABLE TYPE AS

  CREATE OR REPLACE

  TYPE GOTYTA_EQUI

  AS THE GOTYOB_EQUI TABLE;

  1. 3 create a function, it returns the TYPE of the TABLE

  FUNCTION fn_equiposarriba)

  pa_nucomp in NUMBERS

  pa_anperi in NUMBERS

  pa_meperi in NUMBERS

  )

  1. 4 SQL Query with the help of the function... you can use this SQL in a display object

• REP-0737: must be a function of return type 'ref cursor.

  Hi all

  I have create a ref cursor query in reports 10 g. But it is giving error REP-0737: must be a function of return type 'ref cursor.

  Here is my code

  function QR_1RefCurDS return sys_refcursor is
  
   My_Cur Sys_Refcursor;
  begin
    Open My_Cur for select * from scott.emp order by deptno;
    return My_Cur
  end;
  

  fate of the screen.

  

  Oracle Forms/Reports has a complete PL/SQL engine and (only) the SQL parser.

  However, the engine of forms/States PL / SQL and SQL Analyzer are at a level that was in the Oracle 8.0 database.

  So, in the forms/States functions/procedures and forms/States triggers, you can not use SQL commands that did not exist in the 8.0 database.

  The predefined SYS_REFCURSOR type is introduced in Oracle 9i.

  Use this:

  PACKAGE test_rc IS

  TYPE of rc_type IS REF CURSOR RETURN emp % ROWTYPE;

  END;

  FUNCTION RETURN QR_1RefCurDS Test_rc.rc_type IS

  test_rc.rc_type RC;

  BEGIN

  OPEN the RC to SELECT * FROM emp;

  RETURN rc;

  END;

• using plsql table and ref cursor in oracle's 10 g

  I want to fill in the data in the forms manually is not using Forms data block Wizard and by program.
  
  Please answer...

  Can someone give me an example of a scenario where we need to create a form manually based on a stored database procedure.

  In general, you will use a block of proceedings based when you have a collection of data from several tables presented in a form and your username must be able to update the information displayed.

  In your sample code, looks like you are using Oracle Support document "Melting a block on a Stored Procedure - examples of Code [ID 66887.1]". If this is the case, continue to follow the document - it guides you through all the steps. There is no need to manually configure things that the data block Wizard will work for you!

  I want to fill in the data in the forms manually is not using Forms data block Wizard and by program.

  Why? Let the wizard block configuration data of your block based on a procedure for you. There is no need to manually browse the data! I did what you're trying, and it's more work needed. Leave forms to do the work for you. :)

  If you absolutely have to do things manually, I recommend that you use the PROCEDURE bonus_query (bonus_data IN OUT bontab) instead of bonus_refcur (bonus_data IN OUT b_cursor) . Then, in your code create a variable of type BONTAB, and then call the bonus_query procedure. Then, it's a simple case of a loop in the table of records returned by the bonus_query procedure. For example:

  DECLARE
     t_bonus    bonus_pkb.bontab;
  BEGIN
     bonus_pkg.bonus_query(t_bonus);
  
     FOR i in 1 .. t_bonus.count LOOP
        :YOUR_BLOCK.EMPLOYEE_NUMBER := t_bonus(i).empno;
        :YOUR_BLOCK.EMPLOYEE_NAME := t_bonus(i).ename;
        :YOUR_BLOCK.EMPLOYEE_JOB := t_bonus(i).job;
        :YOUR_BLOCK.EMPLOYEE_SALARY := t_bonus(i).sal;
        :YOUR_BLOCK.EMPLOYEE_COMMISSION := t_bonus(i).comm;
     END LOOP;
  END;
  

  This code example shows the basics, but as is the sample code - you will need to adapt to your situation.

  Also, I highly recommend that you look at the article inol listed. It is a very thorough debate on the REF CURSOR. If you have set up using a procedure based on the data source - it is more effective to spend the record table to your form that it must pass a ref cursor Using a ref cursor, you might as well just using a standard called cursor and loops on your named cursor. The effect is the same (a line returned at the same time creating lots of network traffic). Using the table of records is more efficient because the data set is returned if the network traffic is reduced.

  Hope this helps,
  Craig B-)

  The results I get are as follows:
  
  When I OR in the request for get_employees for search parameters, 106 records are returned.
  
  When I AND in the application, not of records returned is 0. It should return 2 records. Why is it not return all records? Any suggestion on how this procedure should be applied?
  
  Thank you

  Hello

  The problem is that you try to implement a dynamic list in a static SQL statement:

  job_id IN '(''AD_VP'',''SH_CLERK'')'
  

  It will not work like that.

  Check out these links for some tips:

• Report regions - use of the Ref Cursor?

  APEX 4.2

  See http://mikesmithers.wordpress.com/2012/02/22/getting-apex-to-play-with-ref-cursors

  The above article is older than 2 years. The techniques shown in the link above still valid today if we want to create a report region in the APEX are based on a function that returns a Ref Cursor? Are there improvements in this area for the next APEX 5.0 and/or database Oracle 12 c?

  Thank you

  If the function returns the ref cursor is the only point of access that you have data then Yes, it probably is. If you have direct access to the underlying database objects and the function does not have something very complicated, then you are probably better off creating your own body of the function returning SQL query data source.

  Everything about the dynamics of ref Cursor now I divided in 2 layers, with a function for generating the dynamic SQL and another for bind parameters open the ref cursor. APEX apps can then reuse the functions of SQL query in function body return SQL query data sources (if you take a bit of care to keep the bind variable names vaguely APEX-point-friendly).

  Are there improvements in this area for the next APEX 5.0 and/or database Oracle 12 c?

  See this for the technical background on why APEX is not yet support ref Cursor and this for more information of the Oracle team on the possibility of future support. Obviously, he did not he in 4.1. I suspect that data REF CURSOR region sources depended on a minimum requirement of DB of the 11.1.0.6 (where was introduced support for the conversion of the REF CURSOR in the cursors DBMS_SQL). As minimum DB for APEX 5.0 version is 11.1.0.7, it would be a possible feature for 5.0, but it is not classified as one.

• PLS-00362: Invalid cursor return type; 'NUMBER' must be a record type

  Hello
  
  Having a little trouble with the following code example provided to http://www.dba-oracle.com/plsql/t_plsql_cursor_variables.htm:

    1  DECLARE
    2    TYPE t_ref_cursor IS REF CURSOR RETURN NUMBER;
    3    c_cursor  t_ref_cursor;
    4    l_row   NUMBER;
    5  BEGIN
    6    DBMS_OUTPUT.put_line('Strongly typed REF CURSOR using SCALAR type. Expect an error!');
    7    OPEN c_cursor FOR
    8      SELECT COUNT(*) cnt
    9      FROM   cursor_variable_test;
   10    LOOP
   11      FETCH c_cursor
   12      INTO  l_row;
   13      EXIT WHEN c_cursor%NOTFOUND;
   14      DBMS_OUTPUT.put_line(l_row);
   15    END LOOP;
   16    CLOSE c_cursor;
   17* END;
   18  /
    TYPE t_ref_cursor IS REF CURSOR RETURN NUMBER;
                         *
  ERROR at line 2:
  ORA-06550: line 2, column 24:
  PLS-00362: invalid cursor return type; 'NUMBER' must be a record type
  ORA-06550: line 2, column 3:
  PL/SQL: Item ignored

  In the code above, SELECT COUNT (*)... returns a NUMBER. I know it's an aggregation function, but it returns a single value.
  Why can't return a value in a column of a row in a NUMBER?
  How can I change the SQL code so that I can do this?
  
  Furthermore, I wonder about the use of FETCH with a count (*)... FETCH is supposed to fetch the next row... How it works when you select an aggregate as County?
  
  Thank you very much
  Jason

  You said the CURSOR to return a NUMBER. And as the text says, he must be a 'record '.

  As you said already FETCH retrieves the next line, if any. A query is a request is a request. It returns a result set. A query that uses aggregates returns a result set. A query that does not aggregate returns a result set.

  Your simple COUNT (*) SELECT query returns a result set that consists of a LINE and a line a ONE COLUMN of type NUMBER. Although there is only one column in the result set, what is returned is a RECORD or a LINE. That's why you have to report your data cursor return type a document using the % ROWTYPE or % TYPE attributes or a record structure.

• The stored procedure PL/SQL - t - it accept the custom Ref Cursor type?
