• How to pass the value of the cursor in the procedure to use as dblink

  Hello

  I have a cursor in the procedure. I am inserting some values into the destination table by querying the source table using dblink. And I'm collecting this db link in the cursor. So, my question is how I will pass on the value of dblink values read from the cursor in each iteration? This is my procedure.

  CREATE OR REPLACE
      PROCEDURE desktop_proc
      AS
        v_name VARCHAR2(10);
        v_dblink  VARCHAR2(10);
        CURSOR db_cur
        IS
          SELECT PNAME,OLTP_DBLINK
          FROM PDATA
          WHERE pname in ('RMA','RNA')
          ORDER BY PNAME;
      BEGIN
        OPEN db_cur;
        LOOP
          FETCH db_cur INTO v_name,v_dblink;
          EXIT WHEN db_cur%NOTFOUND;
          INSERT INTO desktop_lite
            (
              Datestamp,
              pname,
              Db_name,
              Company_name
            )
          SELECT Date_Range,
            v_name,   -- local variable
            dbname,
            Company_name
            FROM
            (SELECT bu.datestamp Date_Range,
                    (SELECT name FROM v$database@v_dblink) dbname,
                    bu.name Company_name
             FROM dboltp.s_org_ext@v_dblink bu
             INNER JOIN com_unique uusers ON (uusers.bu_id = bu.row_id)
            );
        END LOOP;
        CLOSE db_cur;
      END desktop_proc;

• Nested cursor in stored procedure.

  Hello.
  
  I'm trying to extract data from Ref Cursor ON filling by the stored procedure parameter.
  Using the latest version of the ODP.NET (11.2.0.3.0) provider.
  
  My stored procedure:
  
  TYPE cursor_type IS REF CURSOR;
  
  
  PROCEDURE test_proc (p_recordset to cursor_type) AS
  
  BEGIN
  
  OPEN FOR P_recordset
  SELECT 1, 2, CURSOR (SELECT FROM dual 3.4)
  OF the double
  
  END;
  END test_proc;
  
  
  If I remove ' * SLIDER (SELECT 3.4 FROM dual) * "the procedure, everything works fine.
  But when the nested cursor exists in procedure, I'm getting the following exception:
  
  
  System.NullReferenceException is produced
  Message = object reference not set to an instance of an object.

  If I'm changing procedure output parameter signature, to return the value code throws the same exception.
  
  
  I am tempted to google about this problem, but impossible to find at least a topic with the same problem (same exception).
  I've seen a few old threads (from 2004-2005), where people declaring that nested cursors are not supported in ODP.NET.
  On the other hand, I can't find any official publication of the latest version ODP.NET, that nested cursors are still not supported.
  
  I will very grateful, if someone can tell me of sense about this problem. Already stuck on this for a few days.
  Thank you!

  ODP.NET does not support nested cursors.

  Give a line number? I wonder if it might be

  table_year: = table_year();

  that is the origin of the problem. Try to remove and see.

  Better yet, change your code to

  ...

     table_year     table_year_type;
  BEGIN

• Calling a procedure that returns a cursor in a procedure

  Hello
  I have two stored procedures. They both return a cursor as output variables. However, I have another stored procedure that calls these procedures and return their results once again an output variable. I know that sounds strange to want to do something like this, but how can I do this?

  Mikhail says:

  My first procedure returns a cursor. But the cursor is opened on one condition. Like, if PARAM1 = 1 THEN OPEN cursor_1 to SELECT... OTHERWISE, OPEN CURSOR_1 TO SELECT... And the second slider has the same structure. The thing is in the two procedures if I declare that a single CURSOR_1 IN OUT parameter that the procedure will not work. So in both entities, I have two variables IN OUT SYS_REFCURSOR: c1 and c2. Then, in the third procedure I first call the first procedure, then the second. How can I write my third procedure in order to obtain the result two procedures United?

  Why the appellant (3rd procedure) need to have 2 ref Cursor? How will the appellant to "unite" the sliders?

  The actual data, a power of work must be done inside sliders. Not in PL/SQL or other languages. The SQL language is a very powerful and flexible language.

  So if the SQL 2 data sets (or more) must be "United", then you should not use the 3rd procedure and PL/SQL code to do. Should use you 2 sliders.

  You should watch this by using SQL only. The 2 sets of data can be merged, joined, union'ed. You can determine the intersection. You can determine the difference (with a negative sign). It can be rotated. It can be aggregated. It can be cube' ed. Etc.

  This SQL will then be used as a single slider and a unique reference cursor handle will be used to consume the output of the cursor.

  The basic rule to develop Oracle applications is simple. Optimize SQL. Minimize the PL/SQL.

  Use the SQL language to the data of the crisis. No PL/SQL.

• How to filter data in cursors within the procedure

  Hello
  
  Yesterday, I tried all night, but couldn't do it.
  
  I know that is incomplete, I just want to know how to filter the data based on the setting in
  
  Basically, here I want to get only the records that match the id_fichier
  
  
  create or replace PROCEDURE clearing_details (p_file_id in varchar2)
  IS
  strStatusCode VARCHAR2 (6);
  CURSOR PD1 IS
  SELECT COUNTRY_CODE, EOD_MARK OF LINK_STATUS WHERE FILE_ID is p_file_id
  
  
  Can someone help me on this please:
  
  
  Thanks for reading.

  Does do the same if you run the query itself in SQL * Plus with the same value you pass as a parameter?

  Without seeing your data and which parameter you're passing, we will fight help more as the concept itself works great as you have been demonstrated.

• Using of the dynamic SQL and the cursor in a procedure

  Here is the procedure:

  What he does (or what I intend to do)
  take the datas of a whole bunch of pictures and put them in the "XX_JK_XB" table and make a log of the tables covered in xx_jk_logxb give just the source table and the status (OK).
  Now when I run the procedure I get a "missing expression" th ' immediate «insert into xx_jk...»» »
  
  I just can't tell what is the problem here.
  
  clues?

  Seems to me that you are wrong assuming that the binding can be done by name and no position when you use immediate enforcement.

  Example:

  SQL> create table foo_tab( c1 varchar2(10), n1 number );
  
  Table created.
  
  SQL>
  SQL> begin
    2          for i in 1..10
    3          loop
    4                  execute immediate 'insert into foo_tab values( to_char(:1), :1 )' using i;
    5          end loop;
    6          commit;
    7  end;
    8  /
  begin
  *
  ERROR at line 1:
  ORA-01008: not all variables bound
  ORA-06512: at line 4
  
  SQL>
  SQL>
  SQL> begin
    2          for i in 1..10
    3          loop
    4                  execute immediate 'insert into foo_tab values( to_char(:1), :1 )' using i,i;
    5          end loop;
    6          commit;
    7  end;
    8  /
  
  PL/SQL procedure successfully completed.
  
  SQL>
  

  As you can see, 1 PL/SQL block attempts to re - use bind variable: 1 new - and only link once.

  Fact does not work like that - you must link it again. Binding is done by bind - 1 position = 1 to the help of var, 2nd = 2nd bind using var, etc.. Name of the connection variable used is irrelevant and not unique.

• Call a member function from a cursor in a procedure

  Hello people
  
  I'm a newbie in the process of learning of 10 G and oracle. My question is:
  
  I created a type called row_po and set a member function getCost() that returns the total cost of the order with headings like the nested table, which I intend to call from a procedure. In the procedure my SELECT returns more than one record, and that's why I need to use a cursor. For each record, I've got display the order_no, quantity, and the order_cost (qty, and order_cost are part of a nested table headings). I am able to access the order_no and quantity, but do not know how to call the member function to get the order_cost. Here are my steps:
  
  CREATE OR REPLACE PROCEDURE get_podet (part_num number)
  AS
  CURSOR c2 is
  SELECT *.
  OF po, TABLE (in. LineItemList_nestab) tab_po L
  WHERE L.PartNo = part_num;
  BEGIN
  TO crec looped c2
  DBMS_OUTPUT. Put_line (' ORDER NUMBER: ' | crec.) PONo);
  DBMS_OUTPUT. Put_line (' LINE QTY: ' | crec.) Qty);
  {color: #ff0000} * DBMS_OUTPUT. PUT_LINE (' ORDER VALUE: ' |) ''); -order_cost, which must be returned by the member function I mentioned-*.
  {color} END LOOP;
  EXCEPTION
  WHILE OTHERS THEN
  DBMS_OUTPUT. Put_line ('Failed' |) "SQLCODE: ' |" SQLCODE);
  DBMS_OUTPUT. PUT_LINE ('SQL ERROR MESSAGE' |) SQLERRM);
  END;
  /
  
  The red line is where I want to call my function getCost() which is a member of the tab_po in. as stated in my SELECTION.
  
  All thoughts were highly appreciated.
  
  Thanks and greetings

  It's always tricky with objects (or so I think...)

  Modify the query in your procedure:

  SELECT treat (value (po) as row_po).getCost() tot_cost
       , po.*
       , l.*
  FROM tab_po po, TABLE (po.LineItemList_nestab) L
  

  This would make the function:

  CREATE OR REPLACE PROCEDURE get_podet(part_num in number)
  AS
  CURSOR c2 is
  SELECT treat (value (po) as row_po).getCost() tot_cost
       , po.*
       , l.*
  FROM tab_po po, TABLE (po.LineItemList_nestab) L
  WHERE L.PartNo = part_num;
  BEGIN
  FOR crec in c2 LOOP
  DBMS_OUTPUT.PUT_LINE('ORDER NUMBER: ' || crec.PONo);
  DBMS_OUTPUT.PUT_LINE('LINE QTY: ' || crec.Qty);
  DBMS_OUTPUT.PUT_LINE('ORDER VALUE: ' ||crec.tot_cost
  ); -- order_cost which should be returned from the member function i've mentioned --
  END LOOP;
  EXCEPTION
  WHEN OTHERS THEN
  DBMS_OUTPUT.PUT_LINE('Failed' || 'SQLCODE: ' || SQLCODE);
  DBMS_OUTPUT.PUT_LINE('SQL ERROR MESSAGE ' || SQLERRM);
  END;

  my spec is perfectly compiled where the body becomes the error said above.
  
  How to recover this question.
  
  Iqbal

  In spec you have this

  Procedure gillison (x277_rec in ref_x277, rcncd varchar, date, date of tdate fdate);

  In the body, you have this

  Procedure gillison (x277_rec in ref_x277, rcncd varchar2, date, date of tdate fdate) as

  for rcncd in spec its VARCHAR and the body its VARCHAR2. Change both to VARCHAR2

• Confused with cursors in procedures of the Oracle

  Hello
  
  I'm new to PLSQL programming, learning every day.
  I have a request here
  
  I read that if we use explicit cursor in the procedure, then we need to open it, extract it, and then close it, which i did a few examples.
  
  Below is a procedure that is nothing like opening the cursor, extracting data from the cursor - etc then how it works?
  
  create or replace procedure show_empnos (p_deptno number) is
  cursor cur_emps is
  Select empno
  WCP
  where deptno = p_deptno
  order by empno;
  Start
  for e in cur_emps
  loop
  dbms_output.put_line ('EmpNo: ' | to_char (e.empno, 'fm99999'));
  end loop;
  end;
  
  Please notify.

• Newbie - how to import the package, procedures, etc.?

  I used the "data export", the computer of the developer, expoty tables, export procedures, export Packages, etc. in a file
  SQL Developer.
  
  In Sql Developer, how to import tables, import procedures, import packages on my computer "REAL LIVE"?
  
  I want to copy the Package, the copy procedure, etc. 'computing Developer' to computer "LIVE REAL DATA?
  
  
  TIA
  Steve42

  If you have access to 2 databases of your sqldev client (and therefore have connections put in place for both of them), just run the export file obtained from the DB dev as a script (F5), using the connection to the production DB (drop-down menu at the top right).

  Have fun

• CURSOR variable in

  Trawling back through messages, but have not seen a response.

  I want to move a collection to a procedure and do something with this collection.  The procedure can be called from another proc or a c# program.

  Heres my demo

  -create table test and place 2 records in

  create table t_curtest (col1, col2 number number)

  insert into t_curtest

  values (1,1);

  insert into t_curtest

  values (2,2);

  commit;

  create package specification

  SQL > create or replace package pkg_curtest

  2 AS

  3 TYPE t_curtype IS TABLE OF t_curtest % ROWTYPE;

  4 procedure prc_curtest

  5 (v_curvar IN t_curtype);

  6 END;

  7

  8

  9.

  Package created.

  SQL >

  create the package body that takes in a slider and bulk collect into a table

  SQL > create or replace package body pkg_curtest

  2 EAST

  3 procedure prc_curtest

  4 (v_curvar IN t_curtype)

  5 EAST

  6 BEGIN

  FORALL i in 1 7... v_curvar. Count

  8

  9 INSERT INTO t_curtest

  10 VALUES v_curvar (i);

  11

  12 COMMIT;

  13

  14 END;

  15 END;

  16

  17.

  Package body created.

  SQL >

  Now try and move a cursor in the further procedure and we get incorrect types.  what I am doing wrong?  It's whole approach?

  SQL > create or replace procedure call_curtest

  2 AS

  3 cursor c1 is select * from t_curtest; -same table we'll insert to so we know its good

  4 BEGIN

  5. place the cursor in a procedure call.

  6 pkg_curtest.prc_curtest (c1);

  7 END;

  8.

  CAUTION: Procedure created with compilation errors.

  SQL > show errors

  Errors in PROCEDURE CALL_CURTEST:

  LINE/COL ERROR

  -------- -----------------------------------------------------------------

  6/5 PL/SQL: statement ignored

  6/5 PLS-00306: wrong number or types of arguments in the call to

  'PRC_CURTEST '.

  This final procedure call, you declare your cursor of the same type

  create or replace procedure call_curtest
    2  AS
    3  cursor c1 is select * from t_curtest; -- same table as we're inserting to so we know its good
    4  BEGIN
    5    -- pass cursor into procedure call.
    6      pkg_curtest.prc_curtest(c1);
    7  END;
  

  Try declaring the cursor first as type pkg_curtest. t_curtype

  FYI: Just noticed your comment - this is where your assumption is incorrect:

  -same table we'll insert to so we know its good

  You need not even as a TABLE. you need the same type...

• function work at the same time that the work can also do procedure...

  pls tel me major diff b/w cursor implicit vs explicit cursor and function procedure vs.

  What does that mean?

  function to do some work at the same time that work also can make procedure... Why work

  Function has the ability to be used in SQL, but cannot be a procedure.

  Basically, I use the procedure for transactional operation and function for Non-transactional operation. For example, if I have to update a table I would use a procedure to wrap my update statement. And if I have to do some calculations or run some select and return a result of Ref Cursor I would use a function.

  In addition to the technical restrictions of function and procedure its more the choices make us.
