• Fetch cursor object type ref

  Hello! I have a Ref Cursor already opened by an external procedure. I need to fetch it in a table of objects like this
  

  CREATE OR REPLACE TYPE TAB_CUSTOM AS TABLE OF REC_CUSTOM;

  where
  

  CREATE OR REPLACE TYPE REC_CUSTOM AS OBJECT
  (
       my_id     NUMBER(6)
          .......
         ,CONSTRUCTOR FUNCTION REC_CUSTOM RETURN SELF AS RESULT
  )
  NOT FINAL;

  a correct columns, types and size of the open cursor ref.
  
  How can this be accomplished?

  Something like:

  declare
      v_custom_tbl TAB_CUSTOM := TAB_CUSTOM();
  begin
      loop
        v_custom_tbl.extend;
        v_custom_tbl(v_custom_tbl.count) := REC_CUSTOM(null,...);

• 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;

• Ref Cursor and type

  Hi all
  
  I finally got the job of procedure stored Ref Cursor but am stuck on the following. I have this package body:
  
  CREATE OR REPLACE PACKAGE BODY PACK_MYCURSOR AS
  PROCEDURE REFCUR)
  theuserid IN OUT users.user_id%type,
  UserFirstName to users_TableRows) IS
  BEGIN
  OPEN FOR UserFirstName
  Select * from users
  Where user_id = theuserid
  ;
  END REFCUR;
  END PACK_MYCURSOR;
  /
  
  Now it works fine, but I need to have fields of explisit in the select statement, such as "select user_id from users", but when I do that then I would get the error messages of "expression is of the wrong type." Someone knows how to fix this?
  
  Thank you.

  Declare your as WEAK rather than STRONG type ref cursor. In other words, do not specify return rowtype % ROWTYPE in your statement in the specification.

  Declare that:
  TYPE users_TableRows IS REF CURSOR;

• Need the difference between strong Ref Cursor and weak Ref Cursor examples

  Oracle 9.2
  
  It would be great if someone can help understand the differences between
  1 Strong Ref Cursors(return type)
  and
  2. weak Ref Cursor (no return type)
  
  What I read is weak ref Cursor as sys_refcursor is better to use the ref Cursor, because in the case of slider strong Ref object type that will be returned must be declared in advance. It dosent make sense to me?
  
  I start with the examples would be appreciate for advice
  
  Strong Ref Cursor
  
  create the package str_pack
  is
  type sref_type is ref cursor return emp % rowtype;
  SVAR sref_type;
  end str_pack;
  
  Create procedure st_proc (eid in number, c1 on str_pack.sref_type)
  is
  Start
  Open c1 to select empno, ename, sal from emp where empno = eid;
  end;
  
  declare
  str_pack.sref_type C1;
  type rec is RECORD (eid, ename varchar2 number (20), number of sal);
  SheikYerbouti rec;
  Start
  st_proc(10,C1);
  loop
  When exit c1% notfound;
  Fetch c1 into SheikYerbouti.
  end loop;
  Close c1;
  end;
  
  
  There could be errors in the above example but its basically to get a better understanding.
  
  For weak Ref Cursor
  
  procedure of the child
  
  Create procedure child_proc (in number, c1 on sys_refcursor eid)
  is
  Start
  Open c1 to select empno, ename, sal from emp where empno = eid;
  end;
  
  parent process
  
  Create procedure parent_proc (recnum varchar2)
  is
  p_retcur sys_refcursor;
  emp_row emp % rowtype;
  Start
  child_proc (eid, p_retcur);
  loop
  extract the p_retcur in emp_row;
  dbms_output.put_line(emp_row.empno ||) e '|| emp_row. Ename | "wins". emp_row. SAL);
  end loop;
  end parent_proc;

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

  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.

  If you still get error try to getEstimatedRowCount() before defining where clause and see if the error will come up again or not

• I need to create a curved with type text box that heal and return to the next line in the form of curved text. How do I do that?

  I need to create a curved with type text box that heal and return to the next line in the form of curved text. How do I do that?

  1. Draw a set of concentric half circles also spaced, stacked so that the outermost is the most remote.
  2. Use the text tool to add text to the outermost path, thus creating a PathType object.
  3. Select all the paths. Type > threaded text > create.
  4. Text tool: click at the end of the text in the object of PathType. Continue typing.

  

  > If I do that it will not type more.

  A Warp effect is a direct effect. When it is applied to the type of objects, they are still editable text. The chain will deform, however, the text also, not only the paths to which it is attached. Sometimes you want that, sometimes you don't have.

• options of workflow while creating the new project type

  Hey Dina,
  
  I have a doubt on below 2 options that are available in the "Project status, Workflow" tab while creating a new project type.
  
  Activate the workflow for projects
  Activate the workflow for Budgets
  
  Could you explain what what will be the exact flow of two work above, impact if we allow them when creating new project type.
  
  Thanks in advance,
  RPD

  Hello

  These two options will affect any new project created using the type of project you are developing.
  For example, you create a project type called "Capital Construction Projects", designated for individual projects that will be created when your company began construction of a new factory or office, for its own operations.
  For this type of project, you can enable the flow of project work and budgets.

  Later business user creates a new project of this type, for the construction of offices for a new Department, he or she will submit the project for approval. By using the workflow your company would install rules so that system knows which should be the approver of this creation of project, or later, any change in the status of the project.
  Once that project was created the business user need to budget for the expected costs of this investment. Another workflow is now used to submit the budget for approval.

  If unnecessary business rules a formal process for approval of two state changes of project or the base line of the budget of the project, then you need not enable these options for the type of project.

• How to create a cursor on a statement select union?

  Hello
  Using Oracle 10 g RAC + ASM (VERSION 1002000300)
  What is the right way to create a cursor on a statement select union?
  Is this possible?
  
  lines, results in code error PLS-00201: sT: = crsR.STATUS; sS: = crsR.TIME;
  
  Procedure below:
  -----
  CREATE OR REPLACE PROCEDURE BUILD_SUMMARY IS
  
  CsrO CURSOR IS
  SELECT
  STATUS,
  TIME
  DE)
  SELECT
  STATUS OF SUBSTR (DESCRIPTION, 1, 50),

  The results of changes in the same PLS-00201 error messages stating the: identifier ' CRSR. STATUS must be declared
  and the identifier ' CRSR. STATUS must be declared
  ...
  FOR Scrr IN csrO
  LOOP
  sT: = crsR.STATUS;
  sS: = crsR.TIME;
  DBMS_OUTPUT. Put_line(St ||) ' ' || sS);
  END LOOP;

  You are not running what I posted here.

  Please replace this line here:

  FOR csrR IN csrO 
  

  to do this:

  FOR crsR IN csrO 
  

  It helps if you name your variables and objects after something more meaningful and less complicated, for example:

  FOR cur_rec IN csrO
  LOOP
    sT := cur_rec.STATUS;
    sS := cur_rec.TIME;
    DBMS_OUTPUT.PUT_LINE(sT || ' ' || sS);
  END LOOP;
