Binding of varchar2 twice to the cursor on DB_LINK

• Get the bind variables name string SQL or the cursor

  Hello
  
  Is there way to get of the bind variables name string SQL or the cursor?
  
  Example of

  DECLARE
    l_sql VARCHAR2(2000);
    desctab DBMS_SQL.DESC_TAB;
    curid   PLS_INTEGER;
  BEGIN
  
    l_sql := 'SELECT * FROM emp WHERE mgr = :X and deptno = :Y';
  
    curid := dbms_sql.open_cursor;
    dbms_sql.parse(curid, l_sql, dbms_sql.NATIVE);
    ....
  END;

  What I mean with the SQL string:
  I love to get using some functions from above code variable l_sql all the bind variable.
  In this case the function should return array where is for example: X and: Y
  
  Back to bind the cursor variable names, I mean same but rather string I pass number of cursor.
  
  Y at - it sucks ready function or some may share a code customized for this purpose?
  
  Thanks
  
  Kind regards

  I found there are wwv_flow_utilities.get_binds of the function not documented in APEX packages that do what I want.
  Usage example

  set serveroutput on
  DECLARE
    binds DBMS_SQL.varchar2_table;
  BEGIN
    binds := wwv_flow_utilities.get_binds('select :P1_TEST from dual');
    FOR i IN 1 .. binds.count
    LOOP
      dbms_output.put_line(binds(i));
    END LOOP;
  END;
  /
  
  anonymous block completed
  :P1_TEST

  But I would not use these functions without papers as those who can change or there is no future versions APEX.
  Is there a documented function or the custom function that do the same thing as wwv_flow_utilities.get_binds?

  Some old basic example code of my friends. Also the media getting the bind variable of PL/SQL code blocks anon.

• How to assign values to the current element where the cursor is?

  Hi all

  I have a block of "tabular" data, B_Emp (from the Employee table) and the other non-database & non tabular block consisting of a text_items B_Test.

  'Emp_id' is one of the column in the Employee table and I want to attribute all the values of the Emp_id in all text_items of the B_Test in order, when you press a particular key.

  Here's what I wrote in the trigger

  Declare

  i the number;

  number of l_last_record;

  next varchar2 (40); -to hold the values of cursor system of the next item in the block of B_Test

  next_r varchar2 (40); -to hold the values of cursor system of the next record in the block of B_Emp

  Begin

  go_block ('B_Emp');

  Set_Block_Property ('B_EMPLOYEES_ALL', DEFAULT_WHERE, "Emp_id is not null");

  execute_query (no_validate);

  last_record;

  l_last_record: =: system.cursor_record;

  premier_enregistrement;

  next_r: =: SYSTEM. CURSOR_ITEM;

  go_block ('B_Test');

  Next: =: SYSTEM. CURSOR_ITEM;

  because me in 1.l_last_record

  Loop

  go_item (Next);

  : next: =: B_Emp.Emp_id;-here is the problem

  next_item;

  Next: =: SYSTEM. CURSOR_ITEM;

  go_item (next_r);

  next_record;

  next_r: =: SYSTEM. CURSOR_ITEM;

  WHEN THE OUTPUT: SYSTEM. LAST_RECORD = "TRUE";

  End loop;

  End;

  Now, this gives me the expected bad Bind Variable error as there is no block of data with the name "next".

  However, I checked the value of 'next' and 'next_r' (message (' value = ' | next)) and I'm getting the expected values.

  So if somewhere, I am able to put my value in the current item the cursor (because at the beginning of the loop, my cursor system is exactly to the text element where I need to insert the value) so I did not have to use this " : next: =: B_Emp.Emp_id;"

  OR

  If somewhere, I am able to return the items in my B_test block dynamically so I can simply use

  Loop

  ": B_test." dynamic reference for the element ": = : B_Emp.Emp_id;

  next_record;

  WHEN THE OUTPUT: SYSTEM. LAST_RECORD = "TRUE";

  
  

  
  

  Please help me out of this!

  Guy! I found a solution for the same thing.

  We can use integrated a 'copy' to set the values of the element where currently is cursor system.

  The syntax will be

  Copy ((new_value): System.Cursor_Item);

  -where new_value is the variable that contains the data to be assigned.

  In addition, we can assign the values from the system cursor to any variable.

  The syntax will be '

  new_value: =: System.Cursor_Value;

  Thanks a lot guys for your help and concern

• Cursor of return of (nested) function - PLS-00201: identifier of the CURSOR must be declared

  Hello

  I have a function in which I use nested functions (because I don't want to create objects explicit / external, it is a requirement that I don't have any effect on / I don't want to change).

  In my external function, I use cursor by declaring them in IS-section and then open using the loop for instruction.

  In my inner function / nested, I also want to use a cursor.

  There I also said one like I did in an external function within the section IS of the nested function.

  SQL Developer complains about syntax error (';: wait ").

  When you try to compile the whole process I get the following error:

  "Error (97,14): PLS-00201: identifier 'CURSOR' must be declared '.

  It's my external function starts as:

  CREATE OR REPLACE FUNCTION FN_GENERATE_QUERY_PMT (instance_id_in IN NUMBER, language_in IN VARCHAR2)
  RETURN CLOB
  IS
       CURSOR c_outer IS
        SELECT * FROM BLA;
  

  When it comes to my internal function with the section IS of the external function and stands (inner functions should be at the end of the Section IS to stand behind the statements of variable and cursor, otherwise there will be an error):

  FUNCTION nfn_get_value (num_in IN NUMBER)
        RETURN SYS_REFCURSOR
      IS
        SYS_REFCURSOR c_inner IS
        SELECT *
        FROM BLUB;
      BEGIN
        RETURN c_where_in;
      END;
  

  After that there will be another nested function, then the BEGIN section will appear.

  When looking for 'function returns cursor' I can only find solutions where the cursor is declared in section IS (sometimes its an AS-section o_O * worried *) but wihtoug select, just declare type.

  The cursor focus is added in the Begin block to the way open for instruction. But I don't want to open it yet. I want to open the cursor using the loop statement. I am able to reopen? used can it be two sliders while one will not be closed properly?

  How to fix to return a cursor that I can use in my external function.

  Advice would be appreciated.

  Thanks in advance.

  Maybe I got the soultion
  First of all, I found this thread:

  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:5241391331097

  said the following:

  2) a ref cursor is just a cursor.  a ref cursor is just a cursor.  a ref cursor is just a cursor.... (keep saying it over and over
  

  But fortuneately I also found this post:
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:14188501024541

  where thankfully someone shared her knowledge with others:

  In view of this block of code - you may see more "prominent" unlike - any

  How many times you run this block - cursor C will always be select * twice.  The ref

  cursor is not guaranteed.

  Another difference is that a ref cursor can be returned to a client.  a plsql 'cursor cursor.

  cannot be returned to a client.

  Another difference is a cursor can be global - a ref cursor cannot (you cannot set

  them outside a procedure / function)

  Another difference is a ref cursor can be passed to the subroutine - a subroutine

  cursor cannot be.

  This explains why the samples seem always fair with open (Ref) cursor within the section to START.

  I expeceted this (as I wrote in the first post) and ask if the course of opening will be sent back twice or just redirect. I suppose it it reassigns who were just a little in performance.

  But I can't yet find this good explanation of this type anywhere within the documentation and of course I didn't read it all. Shame on me, but I'm always engaged by internet download.

  I would be grateful if someone could say my last statement and leave a comment on double-distribution of the refcursors has reopened.

  Thanks in advance.

• Open with the cursor

  Greetings-
  
  I have a block of code on a report in the grid control, and it works well.
  What bothers me is that I need to specify the parameter in the
  Open the cursor so many times. I know that there is an easier way.
  Here is a simple example of this article:
  
  
  T1d: = sysdate - 90
  
  my_str: = ' select * from my_table where collection_timestamp
  between: 1 and (: 1 + 1)';
  
  my_cursor cursor open for my_str using t1d, t1d.
  
  However - in my code I use this about 24 times. Any help would be appreciated.
  
  Thank you

  Rate the original question when you asked it... However, it is possible to 'normalise' your bind variables in the query using subquery factoring for example

  declare
    dt1    date;
    my_str varchar2(32767);
  begin
    dt1 := sysdate - 90;
    my_str := 'with t as (select :1 as dt from dual)
               select *
               from my_table, t
               where collection_timestamp between t.dt and (t.dt + 1)';
  
    open cursor my_cursor for my_str using dt1;
    ..
  

  If you are linking to the weighted subquery just inside, and then this subquery is used throughout the application to provide the values.

• Function of the cursor

  Dear all,
  
  I got a general question about the features of a cursor.
  
  I got a slider that has multiple where conditions such as
  
  CURSOR C_EMP(p_empno NUMBER, P_ename in varchar2) IS SELECT EMPNO, ENAME FROM EMP WHERE EMPNO is P_EMPNO AND ENAME = P_ENAME;
  
  Suppose I spent where different conditions at this cursor, ORACLE doesn't all the features like PARSING, SYNTAX as a Where condition checking etc is evolving (GOLD) Oracle will bind the values during the execution of the cursor so that it is PARSED but EXECUTED MULTIPLE times.
  
  
  Receive your answer on that.
  
  Thank you
  MK.

  Hi Maddy,

  Cursor is a district of merory where is the analysis of the SQl statement.

  If you change a condition surely new analysis view will be.

  CURSOR C_EMP(p_empno NUMBER, P_ename in varchar2) IS SELECT EMPNO, ENAME FROM EMP WHERE EMPNO = P_EMPNO AND > ENAME = P_ENAME;
  CURSOR C_EMP(p_empno NUMBER, P_ename in varchar2) IS SELECT EMPNO, ENAME FROM EMP WHERE EMPNO = P_EMPNO AND > ENAME = P_ENAME and (other condition);

  the two above statements are different from each other that so surely a new analysis view will be.

  But if you use bind variables in the sliders, then no new analysis in view will be, it will be just exceute...

  As you can see, 1 PL/SQL block attempts to re - use bind variable: 1 new - and only link once.

  Fact does not work like that - you must link it again. Binding is done by bind - 1 position = 1 to the help of var, 2nd = 2nd bind using var, etc.. Name of the connection variable used is irrelevant and not unique.

• When you type in Firefox, the cursor moves to the left while everything is written backwards.

  Recently, whenever I try to type so that Firefox 9.01, the cursor moves to the left while everything is written backwards. I can normally type into a word document to have done with it and cut and pasted in this message. I use Windows XP. I closed Firefox and restarted my computer twice with no success to solve this problem.

  Maybe this recent thread on the issue even helps.

  Hi, while writing an email online using Firefox 3.6.3, I was using one of the "CTRL + left arrow or right" to move the cursor on the text. I must have pressed some other key because the screen has become huge - and I can't scroll vertically or horizontally, which makes the pages of Mail of Hotmail impossible. I have connected since using the Explorer MSFT and it works very well. This problem occurs only on the page of Mail of Hotmail Live not on the home page or other.

• If I'm totally off power to my PC, (storm in the region) to reset, the cursor appears, but will not move until I restart again.

  If I just powerdown (overnight), leaving a/c, connected, the cursor appears and moves, as my mouse moves.  HOWEVER, if I powerdown and completely disconnect the PC, 110V, to keep safe from one close shot of lightning, THEN the problem appears.  After the storm passed, I plug the PC into the 110 outlet, turn on the computer and restart it.  The cursor appears in the center of the screen, but it will not move when I move my mouse.  THE ONLY THING I can do is hit briefly, the power button to turn off the back and then click New to reboot (twice now)... then the cursor appears in the center of the screen and moves when I move my mouse.

  Yes, I still think it's the battery.  If the computer is turned off but still plugged into the wall, food always provides a small amount of power to the motherboard to keep a ready"" State.  In fact, if you stop it, but keep it is plugged, you can send a packet to 'Wake-on-LAN' through the Ethernet that would then turn on your computer so you don't have to press any button at all.  This requires that some things are always under tension even when the rest of your computer is turned off.  Remove the plug from the wall removes this standby power and now the BIOS of your motherboard must hold his memory by falling back on the battery.

• HP 520-1165a TouchSmart desktop PC, touchscreen random takes control of the cursor

  When you "touch"touch screen, a small diamond seems to take the place of the mouse cursor, correct."

  I have a problem with my PC, if the cursor of the mouse is in use, the touch diamond screen will be "pop up" and take control of the cursor at random intervals, interupting what I was doing at the time, or automatically the link located in the center of the screen at the time of opening.

  The "pop up" diamond is always in the same 2 places, for the most part, dead center of the screen, but occasionally also appears at the bottom left of the screen by opening the menu of windows automatically.

  In this case the on screen keyboard tab also appears on the side of the screen.

  By clicking on the mouse takes control back to the mouse cursor, but it gets very frustrating because it can occur more than once in an hour and becomes increasingly more regular.

  I had this same problem about a year ago and was covered by my warranty from suppliers, but it took 6 weeks for delivery - repair - return of my PC and I don't want to wait that long again. They had to reinstall my whole system and all information, downloads etc... have been lost. Fortunately I got the majority of my backup files, but it was still a pain to restore all when it's obviously a problem with this PC.

  I love my HP PC and no other issues with performance. It's my player of social media, my music player, my movie player, my full entertainment system, and this insidious problem is purely a gene.

  I very rarely use the touchscreen function, is possible to dissengage this feature to possibly fix my problem?

  Any suggestions would be greatly appreciated.

  Yours Sincerely

  Phil ward.

  NB: Yes, I cleaned the screen, and no, it's not a random flying insect, activation of the touch screen (although this happens :-))

  PS: It has happened twice while compose this letter.

• The cursor moves at will while I type and live your work I've done. I can trash the model

  Is it possible to reduce the sensitivity of the mouse pad?

  I have a laptop that is still under warentee.  It has been in the repair shop and I contacted HP support twice.  I can't type a full sentence without the cursor to jump to another location and screwing up what I already typed.  I know there is a double click on the mouse pad to turn off, but this is unacceptable, because I have to keep turning to move the slider to a different spot to activate a function then shut off again.  I can be: go back to HP for a real computer, or, let the neighbors dog chew on it for a few days then throw it in the trash?  I have a HP printer that works fine for me, but for the money spent on this computer, I do not think that all other HP products are in my future if this problem is not resolved quickly.

  At this point, there wasn't anyone who seems to understand how to fix it.  The phone Wizard really tried to find a solution, but it probably wasn't something that was covered in her flip chart.

• changing value of text with the cursor

  Hi you all

  I need a help from your side

  I have created a slider and change the size of the listview text with the cursor

  Here is my code

   Slider {
                         id: slider
                          fromValue: 8.0
                          toValue: 16.0
                          value: 8.0
                          layoutProperties: StackLayoutProperties {
                              spaceQuota: 0.1
                          }
                          preferredWidth: 200.0
                          maxWidth: 250.0
                          preferredHeight: 20.0
                          visible: true
                          enabled: false
                          horizontalAlignment: HorizontalAlignment.Center
                 onImmediateValueChanged: {
  
  // descriptionText is the id of label
            descriptionText.textStyle.fontSize = FontSize.PointValue
             descriptionText.textStyle.fontSizeValue = immediateValue
                          }
  
                      }

  problem I am facing is, it does not find the descriptionText variable, which is the id of the label

  can someone help?

  OK, the problem is that listItemComponents attached to a control, such as ListView have their own context. ListItemComponent documentation refers to what I think. If you must do the following:

  1. do you have a property that is defined as an attribute of the ListView

  2 bind your fontSizeValue to listItemComponent tag to the ListView. Note, however, to do this, you need to get a reference to the ListView using your label ListItem.view is found in the container. Not obvious, I know.

  3. do you have your cursor to update the property you have defined for the ListView.

  Cursor---> p_font_size ListView property<---------->

  Like this:

  {To ListView
  ID: myListView1
  property real p_font_size: 10

   

  listItemComponents:]
  {ListItemComponent}
  type: 'point '.
  ID: sample

  {Of container
  ID: mainListViewContainer

  {Label
  ID: descriptionText

  ..........
  textStyle.fontSize: FontSize.PointValue
  textStyle.fontSizeValue: mainListViewContainer.ListItem.view.p_font_size

  }

  and elsewhere on your page

  Slider {}
  ID: slider

  fromValue: 8.0
  toValue: 16.0
  value: 8.0
  layoutProperties: {StackLayoutProperties}
  spaceQuota: 0.1
  }
  preferredWidth: 200.0
  maxWidth: 250,0
  preferredHeight: 20.0
  visible: true
  enabled: true
  horizontalAlignment: P

  onImmediateValueChanged: {}
  myListView1.p_font_size = immediateValue
  }
  }

  I test it and it works. Please make this response as the solution if it works for you too :-)
