• conditional view using body of the Pl/SQL function returning a Boolean

  I have problems with the conditional display of a report.
  
  I have to select list: p50_facility and p50_supervisor.
  
  I entered the Sub function body of pl/sql returning a Boolean
  
  Begin
  If (: p50_facility is null or)
  (: p50_supervisor is null) THEN
  Return False;
  On the other
  Return True;
  End if;
  End;
  
  No matter what values are my articles on (null, not null), the report shows.
  
  What I am doing wrong?

  Hello

  The list values will be null only until the first time that the page is sent. Subsequently, the value is likely to be "null %."

  You should do something like:

  BEGIN
   IF (:P50_FACILITY IS NULL OR :P50_FACILITY = '%' || 'null%' OR :P50_SUPERVISOR IS NULL OR :P50_SUPERVISOR = '%' || 'null%') THEN
    RETURN FALSE;
   ELSE
    RETURN TRUE;
   END IF;
  END;

• is it possible to pass the value of the variable validation function return Boolean message?

  

  Assume that L_BATCH_NAME is the name of the variable which will receive the value as

  declare

  l_batch_name: = "NA";

  BEGIN

  L_BATCH_NAME: = FUNCTION (PARAMETERS);

  IF CONDITION > 0

  THEN

  RETURN FALSE;

  ON THE OTHER

  RETURN TRUE;

  1. create a hidden item I say P1_HIDDEN_ITEM

  2 type the error message for this element in your process of

  declare
  l_batch_name:='NA';
  
  BEGIN
  :P1_HIDDEN_ITEM := FUNCTION(PARAMETERS);
  IF CONDITION > 0
  THEN
  RETURN FALSE;
  ELSE
  RETURN TRUE;
  END IF;
  END;
  

  3 and refer to this element hidden in the error message.

  Record for the batch '||&P1_HIDDEN_ITEM.||' already exists.

• VALIDATION - function returns the error text

  I have a domain that occurs on about 12 pages, I need to post this field with some code
  
  I created a function on the database that performs this validation, I pass the field value to the function and it returns some text of error, or NULL if the value is correct
  
  I can't for the life of figure me out how to call the function of APEX
  
  I've tried everything
  
  FUNCTION RETURN ERROR TEXT, Expression SQL, PL/SQL Expression... nothing works!
  
  to call the function my comand is
  
  FN_VALIDATE_HR1_REF (: P1_GCI,: P1_HR1_REF);
  
  I want to return the error on the function text and display it in the banner of APEX error
  
  any help greatly appreciated

  A function like this return error text should work:

  Return (FN_VALIDATE_HR1_REF (: P1_GCI,: P1_HR1_REF));

  Is giving the error?

• Assigning a page element in the region of the "body of function return PLSQL SQL query.

  I've not been here in a long time. I like the new forum text editor!
  
  I have a search page in my application that contains a return region of query SQL PLSQL function body. I use PLSQL to build a query based on the user entries in various page numbers (search text, serial number, year, etc.). Using PLSQL is very useful to enforce the page quickly because there are 1/2 million lines with a lot of text fields some of which are CLOB.
  
  Users want to know how many rows were returned, but if I allow using a paging system that includes the total performance dies because ApEx has to sort through all the pages of output. Instead, I use ' line varies X to Y "without the part of" Z", and it's pretty fast. I can't use the #TOTAL_ROWS # because it does not work with this system of pagination.
  
  So, I built a code within the region of function body PLSQL to build a second query that counts only the lines based on the input parameters. I can do this query within the region using EXECUTE IMMEDIATE and the number to an output variable. The disconnect is that I can not then assign it to a page element. If I add a statement assigned to a page element, either by
  
  : P45_COUNT: = p_count;
  or
  APEX_UTIL. SET_SESSION_STATE ('P45_COUNT', p_count);
  
  then when I submit the changes I get
  
  ERR-1002 unable to find point item ID 'P45_COUNT' in the application '4000 '.
  
  as if the ApEx is not looking for the item in my application, but in the application development environment. I am able to write the results to a table and then recover data in the next region. That's how I got around the problem, but it seems too complicated and unnecessary.
  
  I wrote the following code just to illustrate the problem.
  
  Make sense? Any ideas?
  
  Thank you!

• On the Page validator errors

  Hi I get 4 errors on my site. I think that the errors are flash related so I can leave them, or if anyone of you have any ideas to fix it please let me know. I don't use dreamweaver to integrate the flash then maybe if I use it and make a new animation it wouldn't happen.
  
  Link to the validator is http://validator.w3.org/check?uri=http%3A%2F%2Fwww.theoldfort.com%2Findex.htm & charset =(det ect+automatically) & doctype = Inline & group = 0 & user-agent=W3C_Validator%2F1.606

  Validation errors only that I see that they are related to your use of Flash. If
  you use CS4, just remove the Flash, then reinsert. Who should
  take care of things.

     /* check if chararcter is in ascii range 32 - 127 */

• Bug? -Validations in the processing of the Page

  I think I found a bug in the Validations for the processing of the Page.
  
  If I create a validation of type "Point in 1 Expression contains only characters of the Expression 2", it's as it should be and catches any invalid character.
  
  But, if I create a new liquidation of type 'Error of function return text', this validation works and another one does not.
  
  It is the expression of validation 1 for type validation "function return error text:
  
  BEGIN
  IF: P42_LLP_DECIMAL_DEG_LAT IS NOT NULL
  THEN
  
  IF: P42_LLP_DECIMAL_DEG_LAT <-90
  THEN
  RETURN "decimal latiitude must be between - 90.0000000 to 90.0000000';
  ON THE OTHER
  NULL;
  END IF;
  
  END IF;
  end;

  But, how to integrate the validation of character?

  To be honest, I don't think you should! "Point in 1 Expression contains only characters of the Expression 2" does not guarantee that you have a number, which I think is the intent? (Try something like "5-0"...) There is a built-in "..." is digital""validation"but I have had problems with it. I would use a single validation "function return a Boolean:

  begin
  
    return nvl(to_number(:P42_LLP_DECIMAL_DEG_LAT), 0) between -90 and 90;
  
  exception
  
    when value_error or invalid_number
    then
      return false;
  
  end;
  

  [With ' decimal latiitude must be \[a number\]-90.0000000 to 90.0000000' as the error message in the validation, using the "..." a number...' bit if you want to insist on this.

  The index is in the validation type: function returning a Boolean

  The expression of validation for validation of Boolean function return must be in the form of a function with at least one accessible body return statement that returns a Boolean value:

  ...

  return ;

  or

  return to_date(:p11_event_date, 'DD/MM/YYYY') > sysdate;

  


  in this case:

  return my_package.f_check_date(:p11_season, :p11_event_date);

  However, because the function returns a Boolean value anyway, you might as well use a validation Of PL/SQL Expression and save some typing:

  my_package.f_check_date (: p11_season,: p11_event_date);

• Go to a function that returns a Boolean

  Short version of the question: Boolean values can be returned by a pl/sql function?

  I've implemented a short function which returns a Boolean value; When I compile it I get an error:

  Error report:

  ORA-06550: line 5, column 32:

  PLS-00382: expression is of the wrong type

  ORA-06550: line 6, column 4:

  PLS-00306: wrong number or types of arguments in the call to "PUT_LINE '.

  ORA-06550: line 6, column 4:

  PL/SQL: Statement ignored

  06550 00000 - "line %s, column % s:\n%s".

  * Cause: Usually a PL/SQL compilation error.

  * Action:

  The closest, I appealed

  
  

  RETURN sys.diutil.bool_to_int (< foo >);

  
  

  and then a caller script can call

  
  

  sys.diutil .int_to_bool (< bar >);

  at least this way there is no verification of the Boolean value of 'manual '.  Is it really the only way to return / call a Boolean?

  
  

  Thank you

  EDIT

  
  

  I was aware of the fact I had not provided examples of code - and was just one question fairly open. I hope that this example will show what does not work!

  
  

  I have a function that returns a Boolean value:

  
  

  create or replace

  FUNCTION myFunc (s_in IN VARCHAR2) RETURN a Boolean value

  IS

  s_out BOOLEAN: = TRUE;

  BEGIN

  RETURN s_out;

  END FUNCTION3;

  I try and call the function in the following script:

  DECLARE

  s_in varchar2 (20): = "Hello";

  s_out boolean;

  BEGIN

  SELECT myfunction (s_in) INTO s_out FROM DUAL;

  END;

  That's when I get the error. But sorry, I was looking for too many error messages! I have worked that the one I posted above is because put_line can accept only strings and numbers not Boolean, the mistake that this function returns is:

  ORA-06550: line 5, column 32:

  PLS-00382: expression is of the wrong type

  ORA-06550: line 5, column 11:

  PLS-00382: expression is of the wrong type

  06550 00000 - "line %s, column % s:\n%s".

  * Cause: Usually a PL/SQL compilation error.

  However, I suppose that the comment of Frank Kulash is perhaps the reason why I see this?

  Sure.  If you are having problems, post your code (both the function and some PL/SQL that calls it).

  The BOOLEAN data type exists only in PL/SQL, not in SQL, so if the function returns a BOOLEAN value, then you can't call it in a SQL statement, even if this SQL statement is used within PL/SQL.  For this reason, a lot of guys write functions that return a NUMBER (1 or 0) or a string (' t ' or 'F') rather than return a BOOLEAN value.

  I call this function returning a Boolean in my posting of the page. It doesn't seem to work. It always returns false. What am I missing and is there a better way to do this type of validation. Sorry I'm new to APEX. Thank you very much!

  SmV says:
  Also, I added the part output in the above code and it still does not work. Always returns false.

  When you have a problem in the APEX you can use debug mode to trace what actually demand. It is advisable to include the code of instrumentation in your program units that will generate useful debugging information. To do this, use apex_debug_message API:

  create or replace function hasPageValues (
      p_app_id  in pls_integer
    , p_page_id in pls_integer)
    return boolean
  is
    v_item_found boolean := false;
  begin
  
    for rITM in (
      select
                item_name
              , display_as
      from
                apex_application_page_items
      where
                application_id = p_app_id
      and       page_id = p_page_id)
    loop
      apex_debug_message.log_message(rITM.item_name || ' (' || rITM.display_as || '): ' || v(rITM.item_name));
      -- does the item have a value
      if v(rITM.item_name) is not null
      then
        apex_debug_message.log_message(rITM.item_name || ' is not null: exit.');
        v_item_found := true;
        exit;
      end if;
    end loop;
  
    apex_debug_message.log_message('hasPageValues = ' || case when v_item_found then 'TRUE' when not(v_item_found) then 'FALSE' else null end);

  I need to have my page numbers in the footer somewhere different sheet based on knowledge if it is a page left or right-aligned. Something like this is easily done in Word by checking the option "different odd and even pages.

  Y at - it a similar option in InDesign to get the same result.

  Thank you

  Hello

  Yes, there is.

  You must first make sure that you work in a facing Pages document. Something you select when you create a new document (file > New > Document), or you can change after the fact by choosing File > Document format, and then by selecting the option Pages deal with.

  The document is then formatted with pages of left and right along the spinal column.

  The next step is to apply a master page which consists of a left and right page on the pages of your document and add the footer information page and automatic numbering of the pages on this master page (in a different location for the left and right page of course).

  1. Double-click the Master Page label in the Pages panel to modify an existing master page that applies to your document pages, or select new master from the Pages panel menu to create a new master page design to be applied to your document pages, make sure that you set the number of Pages to 2.
  2. Now add a block of text or other footer information, including a page number 'false' the bottom left and right of the master page, you edit and format as it is on your odd/even pages.
  3. To change the number of fake page to auto page number, use the text tool to select the wrong page number and choose text > insert special character > markers > current Page number.
  4. Repeat step 3 for the page number on the second page.
  5. Double-click on a document page in the Pages panel to return to the document.

  If you opted to create a new master page, you will need to apply it to the pages of a document always.

  1. In the Pages panel, select the pages to which you want to apply the master by clicking on the first page and then Shift clicking on the last page. This will select all of the pages between the two institutions.
  2. In the Pages panel menu select master apply to Pages, select the right apply from the menu of master teacher apply in the dialog box apply master and click OK.
