• SQL (body of function from PL/SQL returning the SQL) query when you use to_char

  We are trying to build a page of Type SQL Query report (body of function from PL/SQL returning SQL query).
  our request is simple, to extract the month of the column recording_date.
  
  declare
  l_query varchar2 (1000);
  Start
  l_query: = 'select to_char (recording_date, 'MM') of re_productive;
  Return l_query;
  end;
  
  but we would like the following for this query problem
  
  Function returning SQL query: query cannot be parsed in the generator. If you believe that your query is syntactically correct, check the box of generic columns below the source of the region without analysis.
  (ORA-06550: line 4, column 42: PLS-00103: encountered the symbol "MY" what awaits one of the following values:.) (* @ % & = - +; <>/ at is mod remains not rem <>or! = or ~ = > = < = <>and or as between | multiset Member SUBMULTISET_ the symbol ".") was inserted before 'MY' to continue.)
  
  Notes:
  1 - the request is correct and it has been tested under sqlplus and toad.
  2. we tried option use generic name (analysis of query runtime only) column, but we get the same problem.
  
  
  any quick help please.

  Hello

  You have not escaped your quote in the string. Try this...

  DECLARE
  l_query VARCHAR2(32767);
  
  BEGIN
  
  l_query:= 'select to_char(recording_date,''MM'') from re_productive';
  
  RETURN l_query;
  
  END;

• Graph based on the function of PL/SQL returning the sql query

  Hello, is it possible to have a chart based on PL/SQL return SQL function as with the reports.
  If I need to present data that is based on the graph and the graph itself, and the report is based on the function PL/SQL, SQL back then how I do the table if this is not possible? Also, is there a way to specify which columns in the report to use for the chart instead of having to specify the same question again on the list - this seems a bit redundant.

  Ah, OK - one HTML table does not offer the possibility of using the PL/SQL (I don't know why, if)

  However, you can create a collection (using the APEX_COLLECTION. Function CREATE_COLLECTION_FROM_QUERY) from your vSQL of string and then basing the chart on that?

  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; ';

• Irregular data loss - function from PL/SQL returning data using Ref Cursor

  Database Version: 10.2.0.4.0 (node 2 CARS)
  
  The high-level process flow is as below:
  (1) insert records in a few tables & commit the same
  (2) call the pl/sql function to extract files (on certain conditions with joins with other tables) of the tables which are filled in step 1.
  -> It uses the ORDER BY clause to queries inline & line number 5000 records return for each call.
  Sense - if inline query is supposed to return 1,00,000 records then 20 calls to the same function. This, because the application cannot contain records beyond number.
  (3) the data returned by the ref cursor is then processed by application (Tibco BW) to generate the flat file.
  
  We are facing the problem of data loss in the file and there is no fixed model. It happens once between 200-300 calls process.
  Resolution: When the problem occurs, triggering the process and in almost every time re-outbreak of the process provides required data.
  
  Guidance on what could be the reason?

  Your SELECT statement is almost certainly incorrect

  SELECT *
    FROM ( SELECT A.HIERARCHY_KEY, B.KEY, B.VAL_KEY, A.KEY_NEW, C.ITEMID, B.VAL_TAG, B.sort_order,ROWNUM ROWNUMBER
             FROM AOD_HRCH_ITEM A, AOD_HRCH_ATTR B, AOD_HRCH_ITEMS C
            WHERE A.outputid = B.outputid
              AND A.outputid = C.outputid AND A.outputkey = B.outputkey
              AND A.outputkey = C.outputkey AND A.outputid = outinstrid
              AND A.outputkey = outinstrkey AND A.ITEM_SEQ = B.ITEM_SEQ
              AND A.ITEM_SEQ = C.ITEM_SEQ AND A.HIERARCHY_LEVEL_ORDER = B.SORT_ORDER
            ORDER BY A.HIERARCHY_LEVEL_ORDER DESC)
   WHERE ROWNUMBER < rownumbereend
     AND ROWNUMBER >= rownumberstart;
  

  Since the ORDER BY is applied after the ROWNUM is assigned in this case, your query is requested for a period of 5000 lines any arbitrariness. It would be perfectly valid for a single line to return in each of your 200 different calls or for a line to return in any of them.

  You definitely want to do something in the sense of the canonical askTom wire

  select *
    from ( select a.*, rownum rnum
             from ( YOUR_QUERY_GOES_HERE -- including the order by ) a
            where rownum <= MAX_ROWS )
   where rnum >= MIN_ROWS
  

  That said, it seems inconceivable that Tibco is unable to manage a cursor that returns more than a certain number of lines. You do a ton of work to return the data pages that are certainly not necessary. Unless you're saying that you somehow paralyzed your installation of Tibco giving him a ridiculously small amount of memory to process, something doesn't look good. A slider is just a pointer - it holds that no data - so the number of lines that you can extract a slider should have no impact on the amount of memory on the client application needs.

  As others have already pointed out, your exception handler is almost certainly do more harm than good. Return the error codes and error messages as from the OUT parameters, instead of simply allowing the exception to propagate deletes a ton of useful information (such as the mistake of the stack) and makes your process much less robust.

• pl/sql returning a Boolean?

  I don't know what the problem with this code:

  declare
  
  l_return boolean ;

  RETURN l_return ;
  
  end;

  as part of the State of the button = "function from pl/sql returning a Boolean"...
  It produces:

• catch the collection returned by the function in a SQL statement

  No specific reason for this? It adds additional complexity to the projection of SQL, and there are additional costs of failover for the motor of PL/SQL (per line) of context. Overall - not your typical approach and one that should have sound justification.

  With regard to the basic method - the SQL multiset() function should be used to create a collection. Here is an example of the approach:

  SQL> create or replace type TFoo as object(
    2          id      number,
    3          bar     varchar2(5)
    4  );
    5  /
  
  Type created.
  
  SQL>
  SQL> create or replace type TFooSet as table of TFoo;
    2  /
  
  Type created.
  
  SQL>
  SQL> create or replace function GetSomeFoo( n number ) return TFooSet is
    2          foo     TFooSet;
    3  begin
    4          foo := new TFooSet();
    5          foo.Extend( 5 );
    6
    7          for i in 1..5
    8          loop
    9                  foo(i) := new TFoo( n+i-1, to_char(i-1,'0000') );
   10          end loop;
   11
   12          return( foo );
   13  end;
   14  /
  
  Function created.

• How to the return type of function from PL/SQL

  Hello
  
  I need to create a function that returns a list of ID, which is stored in a type T_IDs, something like:
  
  search function (searchstring in varchar2) return to T_IDs
  
  I have a little problem with the type within the body of the function using a select statement and filling
  
  Select the id of the table where the text as searchstring.
  
  which is to select a list of IDS corresponding to the where clause. Is it possible to use select in or should I go for another mechanism?
  
  Thanks for all the ideas.

  Bulk Collect works for me...

  Processing of validation error.

  ORA-06550: line 1, column 44: PLS-00221: 'F_CHECK_DATE' is not a procedure or is undefined ORA-06550: line 1, column 44: PL/SQL: statement ignored

  I'm doing something wrong here?  Help, please.

  Thank you

  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);

• function() nested in the select statement

  Oracle 11g. Try to nest a function within the select statement.  Goal: get the average customer rating for each of the qualified user.

  Select user_name, f_get_avg_cust_rating() "Notation.

  of u, OTHER_TABLES o TAB_USER

  where u.id = o.id and another condition matched;

  How Oracle would deal with the sql.  Is it

  (1) first of all display records based on the where clause, then call the f_get_avg_cust_rating() for each of the selected records OR

  (2) for the analysis in tables, the f_get_avg_cust_rating() will be called for each record met?

  Thank you

  Words of Frank, I created two functions with dbms_output and used a function in where clause in select another function. See the bottom of the unit tests. Everyone says, where first clause then select...

  -Where function clause

  SQL > CREATE or REPLACE FUNCTION ret_empno

  2 RETURN NUMBER

  3 AS

  4 BEGIN

  5 DBMS_OUTPUT. Put_line (' where Clause Function');

  6 RETURN 7839;

  7 END;

  8.

  The function is created.

  -Select the function

  SQL > CREATE or REPLACE FUNCTION ret_1

  2 RETURN NUMBER

  3 AS

  4 BEGIN

  5 DBMS_OUTPUT. Put_line ('Select function');

  6 RETURN 1;

  7 END;

  8.

  The function is created.

  SQL > SELECT empno, ename,ret_1

  2 FROM emp

  3. WHERE empno = ret_empno;

  EMPNO, ENAME RET_1

• Authorisation scheme: poll from function from PL/SQL Boolean value

  Hello
  I use with authorisation schemes on page 2 as function of PL/SQL to return a Boolean.
  
  The value of P1_PREF is from page1 (search) report box, driven model type (< class td = "t12data" >#PREF # < table >)
  
  --(lien hypertexte pref) to page 2 P2_PREF.
  
  I tried passing the value (: P2_PREF or: P1_PREF) but it does not work. If I assign (where pref = "100") or any other value it works fine.
  Is it to do with sessions or to store the value in a variable prior to authorization of the page. Please notify.
  
  DECLARE
  v_userrole VARCHAR2 (400) DEFAULT NULL;
  v_staffaccess VARCHAR2 (400) DEFAULT NULL;
  BEGIN
  
  Select USER_ROLE IN v_userrole
  to userrole
  where (upper (USER_LOGIN) = upper(:APP_USER)
  or (upper (:APP_USER)) = 'TEST');
  
  Select staff_access in the v_staffaccess of sm
  where pref = "P2_PREF";
  
  IF INSTR (v_userrole, 'A') > 0
  THEN
  RETURN TRUE;
  END IF;
  
  IF (((v_userrole) = "SP" OR (v_userrole) = 'U') and nvl (upper (v_staffaccess), 'x') do not ("SUPER %')) THEN)
  RETURN TRUE;
  ELSE RETURN FALSE;
  END IF;
  
  END;
  
  Please advise on the passage of the value.
  Thank you very much

  Hi Harinder

  There are many ways this can be achieved. It seems to me that your problem is that the value passed to page 2 is not be updated at each visit?

  So how about this (as only one way to do it).

  Page 1 to P1_PREF
  You press a button or link to go to page 2, that SUPPORTS THE PAGE (important)
  You have a hidden item P2_PREF on page2, who has...

  Source used - always replace any existing value in session state
  Source - point Type

  And then refer to P1_PREF.

  Or you can create a calculation that sets the value of P2_PREF to the value of P2_PREF on the laundry front header.

  Or your button on page 1 could create a branch to page 2 using "defined these elements" "with these values" options in the industry...

  See you soon

• Cannot write the recursive function in PL/SQL

  I'm down to the following without interest in PL/SQL script:

  Set serveroutput on;

  Set feedback off;

  DECLARE

  recursion_counter NUMBER: = 0;

  function countNum (OUT int counter) return a Boolean value is

  Start

  dbms_output.put_line (Counter);

  If counter > 10 then

  Returns true;

  on the other

  counter: = counter + 1;

  countNum (counter);

  end if;

  end countNum;

  BEGIN

  dbms_output.put_line (case when countNum (recursion_counter) then end if 'false' to 'true');

  END;

  I get the following error:

  PLS-00221: 'COUNTNUM' is not a procedure or is not defined

  and I would really like to know why. The error refers to this line:

  countNum (counter);

  DECLARE

  recursion_counter NUMBER: = 0;

  function countNum (int counter) return a Boolean value is

  Start

  dbms_output.put_line (Counter);

  If counter > 10 then

  Returns true;

  on the other

  Return countNum (counter + 1);

  end if;

  end countNum;

  BEGIN

  dbms_output.put_line (case when countNum (recursion_counter) then end if 'false' to 'true');

  END;

• NULL in PL/SQL SELECT statement..

  Hi all
  
  I need to use as a result of a SELECT statement in my function to get PCODE from the table. Cur_rec here. CODE comes from cursor that runs before the declaration.
  
  SELECT PCODE in v_pcode TABLE_XYZ where CODE = cur_rec. CODE and PCODE = 'VIEW '.
  
  
  Now the problem is the part of the CODE has all the information in the table TABLE_XYZ. In this case, it triggers an error NO_DATA_FOUND. To solve it, I can put a part of the EXCEPTION and handle it. But I think in another way...
  
  If there is no data for a CODE, the default value of v_pcode would be 'No Code'. I tried to use the NVL function, but it does not work here as a SQL SELECT statement.
  
  Can someone give an idea how to achieve this?

  Hello

  declare
    ...
    v_cnt number;
  begin
    SELECT count(*)
         into v_cnt
        from TABLE_XYZ
      where CODE = cur_rec.CODE
         and PCODE='SEE';
    if v_cnt=0 then
      v_pcode = 'No code';
    else
      v_pcode = 'SEE';
    end if;
  end;
