  Hello

  % ROWCOUNT SQL would return always 1 be the corresponding number of records would be 0 or infinite. This is because you do count (*), and she always get selected as a line. Let me know your condition of bussiness.

  In addition, you can try this it will give you the result you expect

    declare
       v_count          NUMBER;
    BEGIN
       v_count := 0;
       select count(*) into v_count
       FROM employee
       WHERE id = 5000;
       DBMS_OUTPUT.put_line ('Rows Read = ' || v_count);

• 'Function SQL Query return' using with Flash graphics

  I created a pl/sql function that returns a SQL query in a varchar2 of this form:
  
  Select the null link
  -value > < x value
  < value y of Series1 > series 1 label
  < value Series2 y > 2 series label
  < value of y Series3 > series 3 Label
  ...
  ...
  from tablea a
  Join tableb b
  On a.col = b.col
  order of < x value >
  
  If I call the function of a graphic Flash box series SQL with the Type of Source query "SQL query" value that returns the function like this:
  
  return functionname (to_date ('30-sep-2010, ' mon-dd-yyyy ""))
  
  It parses correctly and the page is saved; However, when I run the page I get no output - error messages or another indication of a problem.
  
  Now, if I call the function in a SQL client, capture the result of the query SQL using the dbms_output and paste that into the box graphic Flash series SQL - change the Source Type of SQL query query - and save the page it works fine when I run it and returns a chart series flash.
  
  Can anyone suggest either;
  
  1. what I might have missed or done wrong?
  2. a way to effectively diagnose the problem...
  
  I tried to use the debugger Apex - what is very nice, indeed - but it provides no information on what might be my problem. I tried to write my own my function debug messages using the apex_debug_message package - nothing...
  
  Thank you

  Hi Eric,.

  Try to pull the source like this:

  begin
     return functionname(to_date('30-sep-2010', 'dd-mon-yyyy'));
  end;
  

  This works very well for me, and if I take the begin-end and the final semicolon from the return statement I get the same behavior as you.

  He doesn't mention in aid of the source (only during the wizard if) this source type must be expressed in this way, but I agree, it would be useful that the tool would validate to this format meets it "Query SQL that returns the function" or give some sort of indication of the sentence. In any case, this should help you will again.

  Hope this helps,
  John

• reload the page when SQL query returns a value

  Hello world

  the title of this discussion may seem strange, but I'll try to explain why I need this:

  A user has the ability to connect on my APEX application. There are several tabs in my application that are visible only if a certain SQL statement returns a value which is not the case by default. The user has also the ability to download a file that is transferred to an external system that analyzes the file and writes the data in the database. During this writing process - which may take several minutes - conditions for some of the tabs to show the will becomes real (-> the query will return a value). When the user refreshes the page manually, the tabs will be displayed. However, I want the tabs will appear automatically when the condition is met.

  Is it possible to refresh the page as soon as the query returns a value? It is perhaps possible to check it on the client side and trigger a refresh of the page when the condition is met. It would be even better if only the tabset has been updated, but refreshing the full page is fine as well.

  Thank you!

  Here is an overview of how it can be done

  This is possible thanks to a dynamic action being performed on a timer.

  View default tabs and dynamic action hide them on loading the page if they are not to be considered

  Create a dynamic action that will execute your query every 5 seconds or more

  If the query returns data, you can use the dynamic action to show your tabs using javascript

  Back AFTER using the exception block is fine as long as your code actually REACHED the exception block.

  When there are no errors, then your code will not enter the exception block, but you still NEED to return a value, since it is what functions a function wants to return a value, that's what the functions are made for.

  Spot the differences between the following 3 functions. Understand how they work.

  The first function has only a return in the exception block but runs correctly. Result: error, because the back is missing in the code block.

  The second function has a return in the exception block and one in the block of code and runs correctly. Result: no error, because the return is not missing in the code block.

  The third function has a return in the exception block and one in the block of code and is forced into an error. Result: no error, because the return of the exception handler is used (instead of retriggering of the error, which you would normally do).

• Do stuff to PL/SQl that returns the value and redirect to modal page by setting this value

  Hello

  a button click Page1 I would perform a PL/SQL procedure that returns a value in P1_ITEMVAL and then redirect to a page 2 (modal page) and the value of an item on this page with the value previously returned. To do the same thing with a normal page is quite easy:

  Button action is present, then process of PL/SQL that returns the value in the P1_ITEMVAL element and, finally, a branch at page 2 that sets P2_ITEMVAL with P1_ITEMVAL. I really have no idea how to do the same thing when the target is a modal page.

  I created a unit test on https://apex.oracle.com/pls/apex (application 1554 - redir_to_modal)

  If you prepare a URL using the value calculated in the PLSQL of DA part you can then use a subsequent stage of javascript to set the location of the window.

  This will jump to the top of the page of the modal dialog box

  : P1_URL: = apex_util.prepare_url)

  ' f ? p ='|| : APP_ID - Application id

  |': 2' - Page id

  ||': ' || : APP_SESSION - Session id

  ||':NO'                    -- Debug

  : ': ' - Clear Cache

  : ': ' - Settings

  ||' P2_ITEMVAL'

  : ': ' - Parameter values

  || (: P1_ITEMVAL);

  then in the action of javascript

  Window.Location.Replace ($v ('P1_URL'));

• SQL ROWCOUNT %

  When I use SQL % ROWCOUNT, it returns the account = 1 if there is no record of the PRODUCT in the condition table

  SELECT count (*) from the PRODUCT v_count WHERE LOC = v_oldloc;

  dbms_output.put_line (' documents found in the PRODUCT table for column LOC with the value ' | v_oldloc |': ' |) SQL % ROWCOUNT);

  COMMIT;

  But, when I use the v_count to display the number of records, it returns ZERO (correct) as below

  SELECT count (*) from the PRODUCT v_count WHERE LOC = v_oldloc;

  dbms_output.put_line (' documents found in the PRODUCT table for column LOC with the value ' | v_oldloc |': ' | v_count);

  COMMIT;

  Please let me know if there is a problem with the code?

  Thanks in advance

  Hello

  % ROWCOUNT SQL returns you the number of lines that returns the query "SELECT count (*) in v_count PRODUCT WHERE LOC = v_oldloc;

  In fact, the query returns a row with the value 0. This is why SQL ROWCOUNT % gives you 1 as output.

  Of course v_count is 0 because it is what is the result of the query.

  Both are expected results in your case.

• SQLCODE and sql rowcount % in test conditions

  I'm translating a procedure of Ingres to oracle. I use the Oracle sql and sqlcode % rowcount
  variables instead of Ingres, iierrornumber and iirowcount.
  
  I replaced the names of ingres with the names of oracle and now wonder how how oracle uses these
  values.
  
  I use DBMS_OUTPUT. Put_line to display the content of rowcount % sqlcode and sql.
  
  What happens when I'm 'without selected lines. I have run the same query in the stand-alone command line
  and don't get any selected rows... "(and that's okay, because I do not have the corresponding data to)."
  
  But when I run it in the procedure, I don't get any value of sqlcode or sql % rowcount... the
  program just stops. The author used the ingres code to test if the data were there
  continue to do something else.
  
  If you get no rows returned, what it means, the sqlcode is 0? and the number of lines % sql is empty?
  That's why my DBMS_OUTPUT. Put_line does not display anything?
  
  my example...
  
  before this section in proceedings... after running another select statement that returns data...
  I use the DBMS to debug the values I spent...
  
  DBMS_OUTPUT. Put_line ('BEFORE sqlcode is' | sqlcode);
  DBMS_OUTPUT. Put_line ('until sqlrowcount is"| % rowcount sql);
  
  Select the table value

  DBMS_OUTPUT. Put_line ('AFTER sqlcode is' | sqlcode);

  When I run the procedure... I get statements DBMS BEFORE and nothing after...

  Sqlrowcount is 1 > > > > that's all that is displayed
  
  
  Given that I'm getting the 'no row returned. How oracle it round to the experience of someone?
  
  Thank you. I learn a lot from your comments and your information.

  Show us the full procedure please.

  I'm guessing that you have a generic WHEN catch of OTHER exception that swallows the NO_DATA_FOUND exception I expect to see (depending on what you posted).

• Is it wrong to use SQL % ROWCOUNT = 0?

  Hello
  
  I have two tables, BILL and VALIDATIONS, have all two (LDAP_UID, TERM) as a composite key. I wrote a procedure to do the following:
  
  1. I use this composite key to extract some the key fields from the table of BILL, form a new row and insert it into the table VALIATIONS;
  2. prior to inserting into the table of VALIDATIONS, I use a SELECT statement to verify if the composite key already exists in the table of VALIDATION and not inserting at least that the composite key is not found.
  
  The procedure is the following:
  

  create or replace procedure save_transactions
     (i_ldap_uid IN varchar2, i_term IN varchar2)
  AS
     v_validated_ldap_uid validations.ldap_uid%type;
     v_student_id validations.student_id%type;
     v_first_name validations.first_name%type;
     v_last_name validations.last_name%type;
     v_term validations.term%type;
  BEGIN
     select ldap_uid
     into v_validated_ldap_uid
     from validations
     where ldap_uid = i_ldap_uid
     and term = i_term;
  
     if SQL%ROWCOUNT = 0 then
        select student_id, first_name, last_name
        into v_student_id, v_first_name, v_last_name
        from bill
        where ldap_uid = i_ldap_uid
        and term = i_term;
        insert into validations values (
        v_student_id, i_ldap_uid, v_first_name, v_last_name,
        i_term, sysdate, (to_char(sysdate, 'yymmdd'))||
        (select to_char(count(TRANSACTION_DATE)+1, 'fm0999') from VALIDATIONS where to_char(TRANSACTION_DATE) = to_char(sysdate))
        );
     end if;
  END;
  /

  The procedure is created and updated clean, without any error. But the error occurs when using it. If the line is already in table VALIDATIONS, the {color: blue} if SQL % ROWCOUNT = 0 {color} is fine and the insertion code block is bypassed. However, if the line is not found in the table of VALIDATION, I got the following error:
  

  SQL> execute save_transactions('john.brown', '200902')
  BEGIN save_transactions('john.brown', '200902'); END;

  ERROR at line 1:
  ORA-01403: no data found
  ORA-06512: at "ZBOV.SAVE_TRANSACTIONS", line 10
  ORA-06512: at line 1

  Well, for me, the whole use of SQL % ROWCOUNT is for testing. If he cannot test SQL ROWCOUNT = 0%, how else can test? However, I got the error and I must be wrong. But what is bad?
  
  Thanks a lot for your help!

  Hello

  The "no data found" error is raised whenevde make you a select... IN the query and the query found no line.
  You can always include SELECT it... IN his own statement BEGIN block, with its own «EXCEPTION WHEN NO_DATA_FOUND» Manager... ", but often, there are easier ways to work around the problem.

  In this example, I can see two of these ways:

  (1) Say

  SELECT  COUNT (*)
  INTO    num_found
  FROM    transactions
  WHERE   ldap_uid = i_ldap_uid
  AND     term     = i_term;
  
     if num_found = 0 then
  ...
  

  "SELECT COUNT...". "without a GROUP BY will always return exactly one line, if you do not have to worry about the error"no data found ".

  (2) a better (but more difficult) solution: instead of making a "INSERT...". Statement of VALUES... ', using the results of the query on the Bill, make a

  INSERT  ...
  SELECT  ...
  FROM    bill
  WHERE   ...
  AND     NOT EXISTS
          (
          SELECT  1
          FROM    validations
          WHERE   ldap_uid = i_ldap_uid
          AND     term     = i_term
          );
  

  In fact, you have PL/SQL to do this (although there are good reasons to have a PL/SQL procedure that does nothing other than this INSERT statement).

  (3) double-click the preference of browser.uiCustomization.state and the content must be highlighted in a small dialog box.

  (4) copy the whole line and paste it into Notepad and save it as a backup.

  (5) in Firefox, click on the button '3-bar' menu > developer > Notepad. Remove the comment that appears and paste data preferably, that must appear on a long line. Click on the "Pretty Print" button to make it more readable.

  So I hope that you can spot the extra toolbars and change them out, taking care to preserve the commas between the elements.

  I don't have the extra toolbars in mine, but I copied and pasted back this spaced format and Firefox was able to handle it well. I went into customize and moved a button, and when I left, Firefox has rewritten the preference set as a single line. Assuming that yours works fine, then you can get rid of the backup from step (4).
