• 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;

• Binding type variable of function return type?

  Hi, is it possible to bind a type variable to a function return type, so that changes in type of variable according to the function return type definition?
  Something like what is happening with TYPE and % ROWTYPE.
  
  Thank you

  Well, not directly. However, if the function returns SQL declared of type you could:

  1. create a dummy cursor that selects the function of double
  2. create a dummy record variable dummy cursor %
  3. create your variable or dummy record attribute type:

• Invalid cursor within the service in pipeline

  The simple example following illustrates a mistake that I am experiencing with development code more complex.

  I try to reuse a complex procedure that I do not have duplication of code and business logic.

  It runs correctly.

  exec PKG_TEST.complex_proc(:p_cursor);

  This property returns an error:

  exec PKG_TEST.select_rows(:p_cursor);

  The error is ORA-01001: Invalid cursor.

  I checked and the cursor is opened and % notfound is false.

  Any ideas?

  Thank you in advance for your help!

  Problem is that your variable v_cursor in SELECT_ROWS is out of scope when the procedure ends.

  So the ref cursor returned by this method cannot be referenced it more.

  If you are on 11g and beyond, a workaround is to declare v_cursor DBMS_SQL cursor (for example an INTEGER data type) and use DBMS_SQL.to_cursor_number / DBMS_SQL.to_refcursor to convert between the two.

  In this way, the query pointed to by the final Ref cursor will always have a valid binding variable when the procedure ends.

  function select_fn( p_cursor in integer )

    v_tab         PKG_TEST.t_tab;

• RETURN type of function table

  Hello

  I read conflicting information about the return type that has a table function must or may use.

  First, I am a student of a book that says:

  Function in pipeline returns the data types:

  The main constraint for the pipeline functions, it is the return type must be a collection type autonomous which can be used in SQL - i.e. a VARRAY or table nested.

  and then in the next sentence...

  More precisely a pipeline function can return the following:

  A stand-alone nested table or VARRAY, defined at the schema level.

  A nested table or VARRAY that has been declared in a package type.

  This seems to go against the first quoted sentence.

  Now, before reading the above text I had done just my own test to see if a packed type would work because I thought I had read somewhere that it would not, and he does not (the test code and this output is at the end of this question). When I arrived in the text above, after my test, so I was naturally confused.

  So, I'm going to PL/SQL reference that says:

  RETURN data type

  The data type of the value returned by a function table in pipeline must be a type collection defined either at the level of schema or within a package (therefore, it cannot be a type of associative array).

  I tried to call a function that returns a collection of VARRAY type packaged in both SQL and PL/SQL (of course below is SQL all in any case) and no work.

  Now I'm wondering what is a TABLE function must use a schema type and a function table in pipeline can use a packaged type?  I see that I created and called a function table but examples of Oracle see the creation and use of a function table in pipeline.

  Edit: I should add that I read the following sentence in the SF book on p609 in * table functions: "this type of nested table must be defined as an element of level diagram, because the SQL engine must be able to resolve a reference to a collection of this kind."

  So that it begins to resemble table functions should return a schema type and pipelined table functions, perhaps because that they don't in fact return a collection, rather they return (RowSource) content, can use the schema types or types of packages. Is this correct?

  Can someone clarify this for me please?

  Thank you in advance,

  But the compilation of the PIPELINED WILL CREATE the schematic function types automatically. And the TABLE function, applied to the PIPELINED function, use these types of hidden patterns.

• Return type of dataframe string identifier

  Hello
  
  If I have to return a dataframe of rqScript which contains the string, how am I suppose to mention it in the return type of rqTableEval.
  
  For example, if the return value of rqScript is

  data.frame (c (1), c("Name"))

  , which is a number and the other string
  Then in the rqTableEval, identify the return values
  

  'select ID, 1 '1' chain of double'

  1 works as an identifier for the numbers but '1' doesn't work, '1' as an invalid identifier for the return string
  
  I tried with the host of permutations "-* ','. '. "\ *", "a" etc., none seems not to work
  
  Can I please get help on which must be specified as an identifier for the string type?
  
  Published by: Kedar Gupte on May 21, 2013 01:52

  Kedar,

  The string must be long enough to accommodate the output. For example, for a maximum length of 10 characters, you can do "Lucy" or cast ('a' as varchar2 (10)). You must also use single quotes instead of double quotes. In SQL double quotes are used to specify the identifiers (such as table names, column names, etc.). In your example, '1' is an unknown identifier. What you need is a string literal.

  Mission is to create a package that will contain the rate of taxation by the State in a packed slider. The package contains a function that can receive a State of 2 character abbreviated as an argument and finds a match in the cursor and return the tax rates for tha tstate. An anonymous block will test the function with the State of North Carolina.
  If anyone can help?

• Initialize the Ref Cursor to avoid ORA-01001: Invalid cursor

  Hello
  
  I write a stored procedure that returns a REF CURSOR. However, there are times when the cursor is not open if certain conditions are not met, so I wonder if there is a way to initialize the REF CURSOR so that the appellant does not receive the "ORA-01001: Invalid cursor" error when you try to work with the cursor, if it has not been opened.
  
  Any help is greatly appreciated...

  The most appropriate way would be the caller to handle the situation. The caller must capture the exception of INVALID_CURSOR and do what is necessary.

  Other suggestions like having a separate Pavilion or a model select all will lead the appellant to act to the particular situation, that slider is not being opened. What is the case with the exception of INVALID_CURSOR raised by oracle.

  All the need for the appellant to do is manage the exception of INVALID_CURSOR and you should be good. And also INVALID_CURSOR is not a mistake, it's an exception that has a special meaning for her. In the case you sense it takes the condition when not together to return a cursor.

• Invalid cursor error

  When I try to run the following pl/sql code, I get error of invalid cursor. Can someone please explain to me where I am doing wrong.
  

  DECLARE
  CURSOR C1 IS SELECT employee_id,last_name,salary FROM employees;
  
  
  EMP_REC C1%ROWTYPE;
  
  BEGIN
  FOR REC IN C1
  LOOP
  FETCH C1 INTO EMP_REC;

  DBMS_OUTPUT.PUT_LINE('Employee Name '||REC.last_name);
  
  DBMS_OUTPUT.PUT_LINE('JOB '||REC.salary);
  END LOOP;
  END;

  Thanks in advance!

  You must decide if you want to open the cursor implicit or explicit:

  You can use:

  Variant1

  DECLARE
  CURSOR C1 IS SELECT employee_id,last_name,salary FROM employees;
  
  BEGIN
  FOR REC IN C1
  LOOP
  
  DBMS_OUTPUT.PUT_LINE('Employee Number '||REC.employee_id);
  
  DBMS_OUTPUT.PUT_LINE('Employee Name '||REC.last_name);
  
  DBMS_OUTPUT.PUT_LINE('JOB '||REC.salary);
  END LOOP;
  END;
  

  Variant2:

  DECLARE
  CURSOR C1 IS SELECT id employee_id, name last_name, id salary FROM arzt where rownum<10;
  
  EMP_REC C1%ROWTYPE;
  
  BEGIN
  open c1;
  loop
  FETCH C1 INTO EMP_REC;
  EXIT WHEN C1%NOTFOUND;
  
  DBMS_OUTPUT.PUT_LINE('Employee Number '||emp_REC.employee_id);
  
  DBMS_OUTPUT.PUT_LINE('Employee Name '||emp_REC.last_name);
  
  DBMS_OUTPUT.PUT_LINE('JOB '||emp_REC.salary);
  END LOOP;

• Doubt about the return type of function

  Hello
  
  Can a function returns a Boolean value in a select query.
  
  Suppose m creating a function... so can we have a return type of Boolean as...?
  
  If so... THN please give an example

  Can a function returns a Boolean value in a select query

  The answer is no. a Boolean is not a SQL data type and may not be used in the SELECT query.
  For the user-defined function to be called in a SQL statement, see http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10471/adfns_packages.htm#ADFNS00908
  Note especially these lines

  "Its formal parameters and its return value (if any) must have built-in data types (for example, CHAR, DATE or NUMBER) Oracle, not types (such as BOOLEAN, RECORD or TABLE) PL/SQL data.

  "There is an exception to this rule: a formal parameter can have a PL/SQL data type, if the corresponding actual parameter is implicitly converted to the data type of the formal parameter" >

• getAttribute: Incorrect return Type

  I use JDeveloper 10.1.3.3 with ADF/BC.
  
  I get a strange error, because getAttribute returns a number, not an object. Is this a known bug? Or what I am doing wrong?
  
  
  In my Module of Application I am retrieving the value of an attribute of a display object:
  
  Number of numWeight = null;
  String strWeight = "";
  Double retrievedWeight = 0.00;
  
  ViewObject reportVo = getMyReportView();
  Line currRow = reportVo.next ();
  
  This gives a runtime error. When debugging, I find that getAttribute returns a number, which is the data type of this attribute.
  Hiowever, the documentation of the api says it must return an object.
  retrievedWeight currRow.getAttrbite("Weight") = (Double);
  
  So I try this and it give a compilation error:
  numWeight = currRow.getAttribute ("Weight");
  
  I need to do it for the
  strWeight = currRow.getAttribute("Weight").toString ();
  retrievedWeight = Double.parseDouble (strWeight);
  
  
  
  private ViewObject getOnlineReportView (String which) {}
  If (which.equalsIgnoreCase ("ABC")) {}
  Return getOnlineReport_ABC();
  } else {}
  Return getOnlineReport_XYZ();
  }
  }
  
  public OnlineReport_ABCImpl getOnlineReport_ABC() {}
  return (OnlineReport_ABCImpl) findViewObject ("OnlineReport_ABC");
  }
  
  public OnlineReport_ABCImpl getOnlineReport_XYZ() {}
  return (OnlineReport_XYZImpl) findViewObject ("OnlineReport_XYZ");
  }
  
  
  Thank you

  Hello

  oracle.jbo.domain.Number is an object as anything in Java which is not a literal is an object. It returns an object, which means it doesn't have a typed value of return, telling you that you must first convert it to oracle.jbo.domain.Number.

• What are the causes of the log of user account on missing cursor in Windows XP? I have two trays of office that they have this same problem. If you restart them the cursor returns?

  What are the causes of the log of user account on missing cursor in Windows XP? I have two trays of office that they have this same problem. If you restart them the cursor returns?

  Hi DaddyJeff,

  1. don't you make changes before the show?
  2. are you referring to the cursor in the area of user password on the login screen of Windows?
  3. when the cursor goes missing, the mouse pointer works on screen?

  It is difficult to say what is causing this problem. If the mouse pointer freezes or stops working, then we recommend you to reinstall the mouse. To do this, try the following steps:
  a. sign in to Windows.
  b. Click Start, click Run, type devmgmt.msc, and then click ok.
  c. in the list of objects, expand mice and other pointing devices.
  d. right click on the sub element and click on uninstall.
  e. unplug the mouse and plug it back.
  f. the Device Manager, select an item in the list, click the Action menu, click scan for hardware changes.
  g. check if the mouse is detected, if so, then install it.

  See mouse USB which is connected to a USB 2.0 hub is not detected by Windows XP

  
  Note: if the problem persists, restore the computer to an earlier time. See How to restore Windows XP to a previous state
