• Problem with cursor query (Oracle 8i)

  Hi all
  
  The following query works perfectly well if I test it in my development environment

  SELECT dt,
        (SELECT 'Y'
           FROM dual
          WHERE EXISTS (SELECT 'x'
                          FROM top_days t
                         WHERE t.date = dt))
  FROM (SELECT to_date(p_date_start, 'dd-mm-yyyy') + LEVEL - 1 dt
                     FROM dual
                   CONNECT BY LEVEL <=
                              to_date(p_date_end, 'dd-mm-yyyy') - to_date(p_date_start, 'dd-mm-yyyy') + 1
                          AND PRIOR dbms_random.value IS NOT NULL) --workaround for oracle 8i
                 ,
                  top_days t
  WHERE dt = t.date(+)
  ORDER BY dt;

  However, when I try to include it in my package (where it is used in a slider) I get a PLS-00103: encountered the symbol "SELECT" when expecting one of the following numbers: (- + mod null other < an ID > etc.)

  CURSOR c_holidays IS 
             SELECT dt,
                  (SELECT 'Y'
                     FROM dual
                    WHERE EXISTS (SELECT 'x'
                             FROM top_days t
                            WHERE t.date = dt))
             FROM (SELECT to_date(p_date_start, 'dd-mm-yyyy') + LEVEL - 1 dt
                     FROM dual
                   CONNECT BY LEVEL <=
                              to_date(p_date_end, 'dd-mm-yyyy') - to_date(p_date_start, 'dd-mm-yyyy') + 1
                          AND PRIOR dbms_random.value IS NOT NULL) --workaround for oracle 8i
                 ,
                  top_days t
            WHERE dt = t.date(+)
            ORDER BY dt;

  Is there something special I don't know for Oracle 8i which prevents me from using this query in a slider? Or am I just missing something blatantly obvious?
  Note: p_date_start and p_date_end are parameters that are filled in the service
  
  FYI: Oracle 8i release version 8.1.7.4.1 and PL/SQL Release 8.1.7.4.0

  Scalar subqueries in the select list have been introduced in SQL 8i but not in PL/SQL 8i. The only solution to use subqueries in the select list in PL/SQL 8i is dynamic SQL:

  OPEN v_ref_cursor FOR '
  SELECT dt,
        (SELECT 'Y'
           FROM dual
          WHERE EXISTS (SELECT 'x'
                          FROM top_days t
                         WHERE t.date = dt))
  FROM (SELECT to_date(p_date_start, 'dd-mm-yyyy') + LEVEL - 1 dt
                     FROM dual
                   CONNECT BY LEVEL <=
                              to_date(p_date_end, 'dd-mm-yyyy') - to_date(p_date_start, 'dd-mm-yyyy') + 1
                          AND PRIOR dbms_random.value IS NOT NULL) --workaround for oracle 8i
                 ,
                  top_days t

• By using a nested as a data source in a cursor query table?

  Hi all
  
  Can you please let me know if we can use a nested table created locally as a source of data in a query of cursor?
  
  I'm doing using the following logic, but on compliation failure with the error: "PL/SQL: ORA-00942: table or view does not exist.
  
  =================================================================================================
  
  DECLARE
  
  N_table_outage_dates TYPE IS an ARRAY OF DATE;
  nt_out n_table_outage_dates: = n_table_outage_dates();
  
  l_outage_date DATE;
  
  cursor l_temp_cursor is
  SELECT DISTINCT APS. VENDOR_ID
  OF AP_SUPPLIERS APS
  WHERE
  (
  Trunc (APS. BUS_CLASS_LAST_CERTIFIED_DATE) + To_Number (FND_PROFILE. Value('POS_BUS_CLASS_RECERT_PERIOD'))
  = Trunc (l_outage_date) + To_Number (FND_PROFILE. Value('POS_BUS_CLASS_RECERT_REMIND_DAYS'))
  AND l_outage_date IN (SELECT * FROM nt_out );
  
  BEGIN
  
  l_outage_date: = SYSDATE;
  
  FOR I IN 1.7 LOOP
  
  nt_out. EXTEND;
  nt_out (i): = l_outage_date;
  l_outage_date: = l_outage_date + 1;
  
  END LOOP;
  
  Open l_temp_cursor
  
  -other logic
  
  close l_temp_cursor;
  
  END
  
  =================================================================================================
  
  The other will be passing the value of 'l_outage_date' to a cursor in a loop and then storing the multiple outputs of the query in a separate table / v-table but it will lead to duplicated being filled, elements that will need some work to do.
  
  Please let me how can know I use the nested table created by user in the query cursor running regarding the above code? Is the statement to go wrong anywhere nested table?
  
  Thank you
  Sylvain

  You currently have

  TYPE n_table_outage_dates IS TABLE OF DATE;
  nt_out n_table_outage_dates := n_table_outage_dates();
  

  He declares nt_out as a type of PL/SQL... the engine SQL (the place that runs queries) can not understand / interpret what it is, because it is declared in a PL/SQL it is not inherited in any way in SQL.

  So you must either create the type in SQL as I showed earlier OR (now that we know your version) get grants on the object laid down by Solomon.

  AND THEN, you need to change

  (SELECT * FROM nt_out );
  

  TO

  (SELECT * FROM TABLE(CAST(nt_out as DEPENDS_ON_WHICH_OBJECT_YOU_CHOOSE_TO_USE) );
  

  As I mentioned earlier in my example.

• Problems using trigger cursor query and post.

  Hello
  
  I use a block non-base of data/model to query records in a database block. My form has a point text 'report No.' that will be used to enter a valid number of reports. Based on the number of this report, I hit a button to search (also from the same block of data non-base) to view records that have this "report No.' in the database block. I think I need to use a cursor in a post for this request but I am not able to operate :( Help, please! I really need this point that nobody is helping me to work:(la figure)
  
  My search button - button the trigger:
  DECLARE
  NUMBER OF CHOICES;
  BEGIN
  IF: DUMMY_BLK. NWTFR IS NULL THEN
  ALERTS. STOP_ALERT ("Start Date is required", choice);
  RAISE FORM_TRIGGER_FAILURE;
  END IF;
  go_block ('T_VESSEL_BLK');
  execute_query;
  END;
  
  My post_query:
  
  DECLARE
  cursor vessel_cur is
  SELECT VES_RPTNO, VES_SENDER, VES_SENDER_MBOX, VES_INTCTRL_REF, VES_NAME, VES_VOYNO, VES_ARRDT
  SHIP
  WHERE VES_RPTNO =: DUMMY_BLK. NWTFR;
  var_mot vessel_cur % ROWTYPE;
  BEGIN
  Open vessel_cur;
  LOOP
  extract the vessel_cur in var_mot;
  EXIT WHEN vessel_cur % NOTFOUND;
  END LOOP;
  close vessel_cur;
  END;

  instead of execute_query you do now

  Why do you offer me something like that? Replacing the standard behavior that you use forms must be well thought out, because you have to manage a large number of possible problems. You can easily get the desired using the standard logic behavior:

  -Create an item number IT_COUNT in a control block, assign 'calculation mode' to 'Summary', 'Synthesis function' to 'Count' "Down block" and your DB-bloc and "just point' a null-element not contained in this block. Last series the block 'Interrogate all folders' to 'Yes' in your databaseblock. Now, in your code, you can just checkl the value of this element of count, as

  ...
  EXECUTE_QUERY;
  IF :BL_CONTROL.IT_COUNT=0 THEN
    error
  END IF;

  Hello

  You must use a REF CURSOR for that (there are a few examples in the Oracle documentation). Here is a code example:

  DECLARE
     TYPE EmpCurTyp IS REF CURSOR;
     emp_cv   EmpCurTyp;
     emp_rec  emp%ROWTYPE;
     sql_stmt VARCHAR2(200);
     my_job   VARCHAR2(15) := 'CLERK';
  BEGIN
     sql_stmt := 'SELECT * FROM emp WHERE job = :j';
     OPEN emp_cv FOR sql_stmt USING my_job;
     LOOP
        FETCH emp_cv INTO emp_rec;
        EXIT WHEN emp_cv%NOTFOUND;
        -- process record
     END LOOP;
     CLOSE emp_cv;
  END;

• REP-0737: must be a function of return type 'ref cursor.

  Hi all

  I have create a ref cursor query in reports 10 g. But it is giving error REP-0737: must be a function of return type 'ref cursor.

  Here is my code

  function QR_1RefCurDS return sys_refcursor is
  
   My_Cur Sys_Refcursor;
  begin
    Open My_Cur for select * from scott.emp order by deptno;
    return My_Cur
  end;
  

  fate of the screen.

  

  Oracle Forms/Reports has a complete PL/SQL engine and (only) the SQL parser.

  However, the engine of forms/States PL / SQL and SQL Analyzer are at a level that was in the Oracle 8.0 database.

  So, in the forms/States functions/procedures and forms/States triggers, you can not use SQL commands that did not exist in the 8.0 database.

  The predefined SYS_REFCURSOR type is introduced in Oracle 9i.

  Use this:

  PACKAGE test_rc IS

  TYPE of rc_type IS REF CURSOR RETURN emp % ROWTYPE;

  END;

  FUNCTION RETURN QR_1RefCurDS Test_rc.rc_type IS

  test_rc.rc_type RC;

  BEGIN

  OPEN the RC to SELECT * FROM emp;

  RETURN rc;

  END;

  exit when emp_cursor%notfound;
  

  also your call to DBMS_OUTPUT. Procedure put_line() is not.

  Clearly the point of my question is being missed.

  Or maybe the question is not been clearly asked. ;)

  I want to set the cursor in the PACKAGE SPECIFICATION, and not in the package body. The issue of the bind variable and the string is neither here nor there because I pass parameters to the cursor.

  What you ask is to use a PL/SQL cursor (defined in the specifications of the package or elsewhere) and that convert a Ref Cursor. N ° cannot be done.
  PL/SQL cursors should be used in the PL/SQL code. REF CURSOR is primary used to pass back a reference to a cursor (and all queries are cursors) to a layer of application outside of PL/SQL for example .net, java, etc.. Once you start using the ref Cursor only really, you have the choice of opening it based on a (dynamic) or a fixed query string as in the examples given. You cannot open a cursor of a PL/SQL cursor definition Ref.

  The difference is that when you do:

    CURSOR cur_mycursor IS
      SELECT ...
  

  you declare a cursor in pl/sql definition, not actually a slider itself. The cursor itself is created when you issue an OPENING or a statement FOR etc. So a Ref Cursor (reference to a slider) cannot refer to the definition of the cursor because it is only a definition, not a cursor (i.e. it has not been sent engine sql and instantiated at that time here). Instead the Ref Cursor must reference a cursor (query), itself, and that may be presented as a string or as the query itself that is issued against the sql engine and then the ref cursor points

  Thus, slider ref and PL/SQL cursors are different concepts, both designed to manage cursors in a slightly different way of programming. You cannot mix them.

• REF Cursor creating CSV files

  Hi guys
  
  I am writing a package to create several different CVS files of the database.
  I created a procedure for each files CVS to be created within the package.
  I set the cursor for each file to each intervention.
  Read slider and concatenate all the fields in a large chain of recording and write it to the file using the UTL_FILE utility.
  
  Is there a way I can create a common procedure and pass all other cases, file_name as a parameter and concatenate all the fields and records and write it to the file? I think the use of the REF cursor, but the problem is the cursor query is different for each file. Some files has 2 columns and some 200 columns.
  No idea how to make this work for any format?
  
  Your help will be very appreciated.

  This allows the header line and the data to write into files separate if necessary.

  for example

  SQL> exec run_query('select * from emp','TEST_DIR','output.txt');
  
  PL/SQL procedure successfully completed.

  The procedure allows for the header and the data to separate files if necessary. Just by specifying the file name "header" will put the header and the data in a single file.

  Adapt to the exit of styles and different types of data are needed.

• Tuninng performance for cursor and insert in the procedure

  Hi all
  
  I need to set the oracle procedure. The procedure is as below.

  SELECT a, b, c and d
  OF ABCD;
  RV_abcd ABCD_CUR % TYPE;

  the cursor query may sing either query or a query to join.
  
  For a single query, I used advice PARALLELS. but I'm not able to find out which suggests that I can use to join as well as what suspicion that I have to use for the INSERT statement.
  also, in addition to and delete, can what advice we use?

  Your entire code can be narrowed in a single SQL

  insert all
    into a(seq_id, a) values (a_seq.nextval, a)
    into b(REF_SEQ_ID, seq_id, b) values (a_seq.currval, b_seq.nextval, b)
    into c(ref_seq_id, seq_id, c, d) values (a_seq.currval, c_seq.nextval, c, d)
  select a, b, c, d
    from abcd
  

• Cursor object and cursor for loop back

  I am beginner in Oracle and the serious database of programming in general. Right now I'm studying the sliders. I more or less understand how works when the cursor returns a record, but I can't understand why this does not work when the cursor return object and I use "cursor for loop.
  
  Here's the test code:
  
  CREATE or REPLACE TYPE typ_Test () AS OBJECT
  text VARCHAR2 (50)
  );
  
  CREATE TABLE t_Test to typ_Test;
  
  INSERT INTO t_Test VALUES (typ_Test('111'));
  INSERT INTO t_Test VALUES (typ_Test('222'));
  
  -work, simple loop
  DECLARE
  CURSOR cur IS SELECT VALUE (o) FROM t_Test o;
  typ_Test obj;
  BEGIN
  Heart OPEN;
  LOOP
  Fetch cur INTO obj;
  OUTPUT WHEN heart % NOTFOUND;
  dbms_output.put_line (obj. (Text);
  END LOOP;
  CLOSE cur;
  END;
  
  
  
  -doesn't work, cursor for loop
  DECLARE
  CURSOR cur IS SELECT VALUE (o) FROM t_Test o;
  BEGIN
  FOR news of obj IN LOOP
  dbms_output.put_line (obj. (Text);
  END LOOP;
  END;
  
  
  
  Error report:
  ORA-06550: line 5, column 30:
  PLS-00302: 'TEXT' element must be declared.
  ORA-06550: line 5, column 5:
  PL/SQL: Statement ignored
  06550 00000 - "line %s, column % s:\n%s".
  * Cause: Usually a PL/SQL compilation error.
  
  
  EDIT:
  In fact I found no examples on the net of its use "cursor for loop" with cursor that returns the object. Only when the record is returned...

  Now, in the 'loop' example for what looks "obj" is a folder, not an object, and 'x' is attribute of this recording... But the cursor must return an object, not a record... What Miss me?

  In the FOR loop "obj" is a pointer to the cursor/query, not a subject in its own right. It gives you just a reference in the query.

  So with that you are referring to the query, but then you need to refer to the column in the query that you are interested, so why there need a name (in my case I called it 'x'). 'x' is the object, and then you refer to the attribute of this object "text".

  In the first request that you simply select the value directly object in a variable, so no matter what it's called in the query values are returned by the position that is the first column in the query goes into the first variable in the INTO clause. Once you have that then the variable itself contains the object, and you can just refer to the attribute within that.

  Hope that makes sense.

• 6i ref cursor no_data_found exception report

  I have a simple report with the cursor query a Ref on a scheme of database packed.
  
  The data model function has an exception handler for no_data_found.
  The exception sets a local variable in a program unit specification.
  A field with a message based on a column in support of place does not return.
  
  I try to give a message to the user and am not having any luck.
  
  Ideas?
  
  Thank you.

  You can create a text field with the text "no data found".
  This field gets a format trigger

  if  then
    return true;
  else
    return false;
  end;
