  Hi Lucie,.

  You are adding and removing a column in a report, so it may be useful to have the extra on the end of the query.
  You get an error? If so, paste it in...

  BUT - that I would put a condition on the column where ': P44_INCLUDE_SUMMARY_FIELD is not null '
  It under 'Attributes of the column' report select the change column icon, and there a breadcrumb "Condition."
  Select "In Expression 1 point value is not Null" and put the P44_INCLUDE_SUMMARY_FIELD in the Expression 1 text box.

  And I have to make it more readable like that when I do the dynamic SQL code:
  IF: P44_INCLUDE_SUMMARY_FIELD is not null THEN
  v_INCLUDE_SUMMARY_FIELD: = ' TBLCASES. SUMMARY summary ';
  END IF;

  v_sql: = ' select TBLCASES. RESEARCHER, researcher,
  TBLCASES. CASENUMBER as CASENUMBER
  TBLCASES. OPENDATE as OPENDATE,
  TBLCASES. ESTCOMPLETE as DATE_CIBLE,
  TBLCASES. STATUS of STATUS,
  TBLCASES. Case CODE case CODE as,
  TBLCASES. FAIR_HOTLINE as FAIRHotline,
  TBLCASES. NYSIG as NYSIGCase,
  TBLCASES. REGION as the region,
  TBLCASES. PROGAREA as PROGArea,' |
  v_INCLUDE_SUMMARY_FIELD |
  ' from TBLCASES where 1 = 1; ';

• '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,

• 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

• Production PL/SQL query: can not find the error

  I have a PL/SQL which produces a query for me, which is used to fill out a report. I use this to supply a filter/search form. Since I want to only filter using xxx movies WHERE = yyy when yyy actually has something else NULL, I use a PL/SQL script in the query I need to produce. However, it does not work as expected and I can't understand why. Here is my code:
  

  DECLARE
    query VARCHAR(1000);
  BEGIN
    query := 'SELECT * FROM F_OBJEKTE WHERE 1=1 ';
    IF :P15_REGION != null THEN
      query := query || 'AND REGION = :P15_REGION ';
    END IF; 
    RETURN query;
  END;

  However, the report still contains all lines, as if P15_REGION has not been defined - and so I guess that the script never enters the IF part. Everyone around who can enlighten me, why it is?
  
  Just another little thing: is there a way I can print debugging messages I see when I press the "Debug" button on the lower bar of APEX? It would help a lot of debugging such PL/SQL functions.

  Try changing

  IF: P15_REGION! = null THEN

  TO

  IF: P15_REGION is not null THEN

• pl/sql - sql query return

  Hi all... I hope someone can help.
  Worked a lot to solve this problem, but I can't find a solution.
  

   
  DECLARE
       lv_sql VARCHAR(32767);
       lv_pivot_cols VARCHAR2(1000);
  BEGIN
       FOR i IN (SELECT DISTINCT comp_name, pro_name FROM  cat_attributes order by comp_name)

  the code above works well, but I want to add a where condition in the separate statement, which depends on an element of the apex.
  as:

  SELECT DISTINCT comp_name, pro_name FROM  cat_attributes where  cat_id=:P1100_CHOOSE_CATEGORY order by comp_name 

  But if an add this condition got
  error report: ORA-01403: no data found
  any suggestions?
  
  
  I would also like to change the size of characters max column header. now, it may be only * 30 * characters for the column header. is there a possibility to raise it?
  
  Thanks for all your suggestions

  Hello

  Hmm. Is the value of ': P1100_CHOOSE_CATEGORY ' in Session State?

  In this case, would be the usual suspect: ": P1100_CHOOSE_CATEGORY" has no value in Session State. You said if she had a value in Session State?

  Now, someone might say, "well, the other query work it must have a value in Session State! Well, maybe. But might work work with null query ': P1100_CHOOSE_CATEGORY '?? If it is null, then get the value stored in the Session State.

• SQL query returns no row vs. multiple lines

  Hello

  Hello

  I think you want to put this on a report or something. I have what would be easier to do this logic there. But if you want that this is possible.
  Like this

  with
  temp_aaa as
  (select '111' a_id ,'12345' b_id from dual union all
  select '222'      ,'12345'  from dual union all
  select '333'      ,'12000'  from dual union all
  select '444'      ,'10000'  from dual
  )
  , wanted_rows as
  ( select  '123456' B_ID from dual)
  select
    temp_aaa.A_ID || temp_aaa.B_ID IDS 
  
  from
    temp_aaa
    ,wanted_rows
  where
    temp_aaa.b_id = wanted_rows.b_id
  union all
  select
    'NO ROWS'
  FROM
    DUAL
  WHERE
    (SELECT COUNT(*) FROM TEMP_AAA, wanted_rows WHERE TEMP_AAA.B_ID = wanted_rows.B_ID) = 0
  

  In addition, you mix var and number of always use the same type or convert explicitly (to_number or to_char)

  WITH
  MATCH_ROWS AS
  (
         SELECT A_ID||B_ID IDS FROM TEMP_AAA WHERE      B_ID           =12345
  --                                                    varchar2(10)   number
  ),
  ...
  

  And again in the

                    THEN
                     (SELECT NVL((SELECT IDS FROM TEMP_AAA WHERE B_ID           =12345),'NO ROWS') IDS FROM DUAL)
  --                                                             varchar2(10)   number

  I can't concatinate columns as this would force the SET NULL option won't do not and using NVL for each column makes the query take too much time.
  
  a post on this thread Re: save output sql command separate values by the States that you cannot force coil of sql to remove spaces, is it true?
  
  all threads in this research http://forums.oracle.com/forums/search.jspa?threadID= & q = colsep & objID = c84 & dateRange = last90days & userID = & numResults = 15 lead me to believe that it is also not possible.
  
  The coil may not have gaps as it is used by some sort of contraption of system before my time to really understand and I said that it's just not having them.
  
  Thanks in advance for any help.

  I think that concatenating your columns with NVL(col1,0) will be your only option. In addition, it didn't really the request that much more time.

• SQL query returning no rows, please help!

  I have a table that contains the user checks for a specific procedures alongwith the date stamp. Now, I want the list of all procedures that are not accessible by users in the last 6 months. Or, all of the procedures that have not been used/accessible during the last 6 months.
  
  That's what I'm trying, but is does not return all rows:
  
  SELECT DISTINCT proc_name,
  TRUNC (entry_date)
  OF log_web
  WHERE NOT IN (SELECT proc_name proc_name
  OF log_web
  WHERE TRUNC (entry_date) > TRUNC (SYSDATE - 180))
  ORDER BY DESC 2
  
  Please notify.
  Thank you in advance.

  Hello

  NOT IN never returns TRUE if the subquery returns NULL values. If proc_name doesn't have a NOT NULL constraint, change the subquery to

  WHERE        proc_name     NOT IN ( SELECT  proc_name
                              FROM      log_web
                       WHERE      entry_date     > TRUNC (SYSDATE - 180)
                       AND      proc_name     IS NOT NULL
                        )
  

  I don't see any other suspect.
  Post a small example of data (CREATE TABLE and INSERT statements) where the query produces results worng.

• Gets the error ORA-01779 after I added the column

  Hi, I'm a total newbie in APEX but collaborated with ordinary development Oracle (tables, views, packages, triggers, etc) for a number of years.
  
  I ve been assigned in order to respect an existing application to APEX. One task is to add a column to a single character named 'ACTIVE' to a database table and also present on a current project list page. The value can be 'Y' or 'n'. In the view which is the source of data for the project page ad 'Y' turned into 'Yes' and 'n' turned into 'no '. So far so good, everything works well.
  
  There is another page on which it is possible to create new or modify existing projects. This page uses a view as a source of data. On this page, I added a group of radiobutton that contains two options: 'Yes' and 'no '. When I select to edit a project in the project list page the second page is loaded and the correct option, 'yes' or 'No', is marked on the page. This group of radiobutton works exactly like a couple of other groups of radiobutton also represented with a single character column in the database. So far so good!
  
  However, when I try to save the project file by clicking on "Apply Changes" I get this error:
  
  ORA-20001: DML error: p_rowid = 50, ID = p_alt_rowid, p_rowid2 =, p_alt_rowid2 is. ORA-01779: cannot modify a column that is mapped to a table not preserved key
  
  What is the problem here? The new 'ACTIVE' column is added to the view, when I run the view I Don t get all records in duplicate, the underlying table has a column id as the primary key.
  
  Since I Don t know that APEX is under the hood it s hard tp what's wrong. Anyone knows the solution to this problem?
  
  / Magnus

  Hello Magnus,

  Is there an INSTEAD OF trigger defined on the view? Have you added the new column ACTIVE there too?

  Hello!
  For some reason, the column of the object on the Inbox of my e-mail account now has the topics of conversation. I have no idea how the son got there - and you would appreciate the help in eliminating these threads.
  Thanks a lot for your help.
