• How to get the query of the region "PL/SQL function body returns the query string"?

  Hello
  
  is it possible to get the query string from the region of type "PL/SQL function body returns the query string"?
  
  I can get the definition of the region as a PL/SQL procedure, but I am interested in the returned query. I tried to write something like
  
  < pre > v_return_query: = «...» » ;
  : P49_QUERY: = v_return_query;
  Return v_return_query; < / pre >
  
  to save the return on hidden item P49_QUERY string, but it does not work. I get the error message: ERR-1002 cannot find the item for the "P49_QUERY" element ID in the application '4000 '.
  
  Kind regards

  If you need to make reference to a page element in the block then you can use this type of control to avoid having to use generic column names:

  if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then-- runtime  :P9_SQL := vSQL;else-- design time  null;end if;
  

  But if all you want to do is capture the SQL debugging you can take all the references element in the block and use the insert statement (in a debug table) as I showed earlier.

• FIRST analytical functions returns the null line

  The following query returns a null line when there is no such thing as a line for the predicate. Is it a bug or expected behaviour. If so what is the meaning of the null row, is it not logical?
  
  
  
  SELECT NVL (max (ah.fyr_end_dt) KEEP (DENSE_RANK FIRST ORDER BY ah.as_of_dt DESC), ' RETURNED NULL')
  Of account_history ah
  WHERE
  Ah.acct_id = 999
  AND trunc (ah.as_of_dt) < = 31 December 08 '

  Moreover, in my example how I distinguish the case where a line really exists, but the column is null when there is no such thing as a line and the FIRST function returns the same value null? Hopefullly I should be able to do it in a single SQL and know the difference?

  COUNT (*) > 0, but COUNT (col_x) = 0, then there is a line, but col_x happened to be null.

  For example, the following query shows that there is 1 row in the group with the lowest name ("ADAMS"), but the column comm in all ranks of this group is null:

  SELECT     COUNT (*)    KEEP (DENSE_RANK FIRST ORDER BY ename)
                            AS total_cnt
  ,     COUNT (comm) KEEP (DENSE_RANK FIRST ORDER BY ename)
                            AS comm_cnt
  FROM     scott.emp
  ;
  

  Output:

   TOTAL_CNT   COMM_CNT
  ---------- ----------
           1          0
  

  The employee whose highest name ("WARD") has a number in the comm column.

• How to get the query execution time without running...?

  Hello
  
  I had one condition... as follows...
  I had 3 sql statements. I need to run only sql what runtime is very less.
  
  Can someone help me, how to get the time query and run this query without using explain plan... ?
  
  Thank you
  Rajesh

  I can't think in any way at all to get the query execution time without running the query.

  You might get an estimate ( approximation ) If you are using explain plan.

  But you have governed to explain plan for a reason, so I can't help you.
  Why you do not want to use don't explain plan?

• Create a branch to function returns the URL - new tab

  APEX 4.2.2
  
  I have a branch of type creates a branch to the function return URL that returns a URL. The branch is triggered via a page element button. The branches of the page at the URL very well but the URL has nothing to do with the application, it is an external URL, so I want to open the link in a new browser tab. Using the link attributes, this is done by using target = "_blank" but I don't see a way to do that in this situation. Seems simple enough, what don't get me? Thank you

  Nothing. It is not possible to do this using a branch as the changing context of the browser should be initiated by the browser, not the server. Use JavaScript to do this automatically:

  window.open('', '_blank');
  

  I'd go with changing the direction if it branches to the original page, setting a value of ASK for use as a condition on dynamic action of The Execution of JavaScript Code that runs the window.open.

• function returning the text validation error

  Hello
  
  I have a page where I can insert/update user, organization, responsible.
  Organization can be nullable.
  
  A single user can both be responsible for an organization.
  
  To check this responsible for validation, I made a function that returns the error of validation of text as follows:
  
  BEGIN
  FOR c IN (SELECT usr_spa
  OF kpi_users
  WHERE usr_org_id =: p22_usr_org_id
  )
  LOOP
  IF upper(:p22_usr_spa) = upper('YES') and upper (c.usr_spa) = upper('YES')
  THEN
  RETURN 'user is already responsible for this organization' |'. ' ;
  END IF;
  
  END LOOP;
  
  END;
  
  The validation works fine.
  
  But it won't when I want to insert a new user, without attributing it to an organization.
  I get the following message:
  
  ORA-01722: invalid number
  
  Cannot run the validation of the "body of the function return text' ERR-1024.
  
  Can someone please help me solve this problem?
  
  Thank you

  Hello

  The user selects a body in a select list? If the default value is considered "null %"? If so, you could modify the test to the IF: P22_USR_ORG_ID <>'% "| 'null %' THEN

• Why the HTTP become function returns the error code 63?

  I tried to use the get HTTP function to get the XML file is returned by the api Google MAPS distance-matrix. I got the right answer if I insert the url directly in the browser, but using the get HTTP function, it returns the error 63, why?

  This is my code (the VI is developed on LV2011).

• Function returning the tree used with the object type

  Hi guys!
  
  I'm fighting for some time now of a function that should return the tree structure of the employees. Let me clarify...
  I have a table say Manager and employees (two columns for an example)
  MANAGER_ID
  EMPLOYEE_ID
  
  Example:
  
  MAN_ID - 1; EMPLOYE_ID - 2;
  MAN_ID - 2; EMPLOYE_ID - 3;
  MAN_ID - 2; EMPLOYE_ID - 4;
  MAN_ID - 4; EMPLOYE_ID - 5
  
  The purpose of my function is back for a specified MAN_ID everyone in the tree...
  
  Example:
  
  RETURN_TREE (1) return {2,3,4,5};
  RETURN_TREE (2) returns {3,4,5};
  RETURN_TREE (4) returns {5};
  
  How to get there?

  What I know is that this feedback from cardinality generates more problems than improving the performance is, in fact, its main objective. But first look at which is was written in the link I posted above

  "Return of cardinality was introduced in the Oracle 11 g database 2. The purpose of this function is to automatically improve plans for queries that are executed repeatedly, _For that the optimizer does not estimate the cardinalities in the properly_ plan"

  If the cardinality feedback kiks in your case it is certainly because you do not have an exact statistics. Get the command the explain plans that I have shown you with the E-lines and A-lines (lines estimates and actual lines) and see where things are poorly estimated.

  If you want to disable the cardinality feedback then add the indicator according to your request

  /*+ opt_param('_optimizer_use_feedback','false') */
  

  Best regards

• Function returns the object type

  I get the following error:, I tried it but no luck on my side

  PLS-00382: expression is of wrong type

  After you create the function, I have to call this function as

  SELECT * FROM TABLE(FUNC_RAT ('NTE','Y','AB','C','Y',NULL))

  Could you please help me with this

  The same basic problem as in your previous thread. Confusion between creating an object from a collection/table of this object.

  Here's a basic example:

  SQL> create or replace type TScalar is object(
    2          id      integer,
    3          name    varchar2(10)
    4  );
    5  /
  
  Type created.
  
  SQL>
  SQL> create or replace type TArray is table of TScalar;
    2  /
  
  Type created.
  
  SQL>
  SQL> --// creating a scalar
  SQL> select TScalar( 1, 'John' ) as OBJ from dual;
  
  OBJ(ID, NAME)
  --------------------
  TSCALAR(1, 'John')
  
  SQL>
  SQL> --// creating an array/collection
  SQL> select
    2          TArray(
    3                  TScalar( 1, 'John' ),
    4                  TScalar( 2, 'Tom' )
    5          )                               as ARRAY
    6  from       dual;
  
  ARRAY(ID, NAME)
  --------------------------------------------------
  TARRAY(TSCALAR(1, 'John'), TSCALAR(2, 'Tom'))
  
  SQL> 
  

  So in your function, you will need to place objects in the collection.

  return(
      Rt_Type_Var(                      --// instantiate the collection
             Type_Rt ('STRT',var1_nri ,liq_Rt,'Stle' ,null)  --// place an object into the collection
      )
  );
  

  And use appropriate type names and the object. Poorly chosen and non standard naming conventions just add to the confusion.

• Calling PropertyUtils.h functions return the error!

  Hello!

  I required the use of certain functions defined in the PropertyUtils.h class in the Photoshop SDK. I used the PIGetLayerName() function. I hoped that everything would be fine, instead an error was returned with the code 30901. I searched the internet, but have found no solution so far. Help, please! I use PS CS5 on Windows.

  Thank you!

  Hello

  I expect an answer to this question...! People, I don't know how to go about this problem... I wanted to know if we can find out if a particular layer is locked or not... The class propertyutils.h in question contains a method, which hopefully can solve my problem... The sound of the name of PIGetTargetLayerLock() with three Boolean parameters. Now, I don't know what type of values to pass to this function, because there is absolutely no info about... I get the same error I mentioned earlier--30901 (errPlugInPropertyUndefined)... Please help me... How to go to this topic... ??? Again, I want to know if we can know through code c ++ If a layer is locked or not...
