• Problem with BULK collect and variable of Table type

  Hi all
  I defined a record type and then set an index - by table of this record type and in bulk has collected the data as shown in the code below. All this was done in an anonymous block.
  
  Then when I tried to set the record as an object type and not the above activities type, I got the below error:
  
  ORA-06550: line 34, column 6:
  PL/SQL: ORA-00947: not enough values
  ORA-06550: line 31, column 4:
  PL/SQL: SQL statement ignored
  
  Could you help me get the result of the first scenario with record type defined as an object?

  Welcome to the forum!

  You should be collecting objects in bulk, something like

  SELECT NUM_CHAR_OBJECt_1  (first_name,
            employee_id)
     BULK COLLECT INTO obj_var
       FROM emp
      WHERE ROWNUM <= 10;

  Help, please

  As Justin has shown, that you want to use BULK collect if you extract the data in a collection.

  for example

  SQL> set serverout on
  SQL> ed
  Wrote file afiedt.buf
  
    1  declare
    2    type t_emps is table of emp%rowtype;
    3    v_emps t_emps;
    4    cursor c1 is
    5      select *
    6      from emp
    7      where rownum <= 10;
    8  begin
    9    open c1;
   10    fetch c1 bulk collect into v_emps;
   11    close c1;
   12    for i in 1 .. v_emps.count
   13    loop
   14      dbms_output.put_line(v_emps(i).empno||' - '||v_emps(i).ename);
   15    end loop;

  If your code is stuck in an infinite loop, you probably left the construction of LOOP in your code. That is not necessary with a big collection, unless you limit the number of rows read and must treat in pieces of defined size.

  If you are planning on extracting data to a load of INSERT statements then consider as being of bad practice.

  You would be better to export the data to a flat file (CSV) and having the receiver of database uses an external table (or SQL * Loader) If you need to load the data back in. A lot of insert statements will be slow.

  If you want to export the data to a flat file, you can use something like:

  As user sys:

  CREATE OR REPLACE DIRECTORY TEST_DIR AS '\tmp\myfiles'
  /
  GRANT READ, WRITE ON DIRECTORY TEST_DIR TO myuser
  /
  

  As myuser:

  CREATE OR REPLACE PROCEDURE run_query(p_sql IN VARCHAR2
                                       ,p_dir IN VARCHAR2
                                       ,p_header_file IN VARCHAR2

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

  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.

• problem with the collection and refcursor

  I have the 'ServerDisconnect2' function below. It should return as 'ref_cursor' on the parameter that is a data container of deleted rows slider, Java developers insist on using this type of data/collection. I don't know how to code to return the values of ID removed as 'ref_cursor '. See commented "open pDeleteList" - sentence, it is commented as does not compile.
  

  CREATE OR REPLACE PACKAGE oe_ctx AS
    TYPE gIntegerTable IS TABLE OF INTEGER INDEX BY BINARY_INTEGER;
    TYPE cursor_type IS REF CURSOR;
  ....
  
    PROCEDURE ServerDisconnect2(pCasinoCode NUMERIC, pCasinoServerCode NUMERIC, pChannelServerCode CurrentLogins.ChannelServerCode%TYPE, pDeleteList OUT cursor_type) 
    IS
      vDeleteList oe_ctx.gIntegerTable;
    BEGIN
      DELETE FROM
      (
         SELECT cl.* FROM CurrentLogins cl, Accounts a
         WHERE cl.CasinoCode = pCasinoCode
         AND cl.CasinoServerCode = pCasinoServerCode
         AND cl.ChannelServerCode = pChannelServerCode
         AND cl.Code = a.code
         AND a.Type = 'lplayer'
         ORDER BY a.code
      ) RETURNING Code
        BULK COLLECT INTO vDeleteList;
        
  /*    OPEN pDeleteList FOR
        SELECT * FROM TABLE(vDeleteList);*/
        
      COMMIT;
    END ServerDisconnect2;

  Is it possible to convert the variable 'vDeleteList' in ref_cursor?
  So my only solution would be to open the ref_cursor BEFORE delete-clause with the same query delete clause has. But I'm afraid that then after opening the instant cursor after a milliseconds the deletion clause removes different lines and the procedure would be data incorrect in pDeleteList.

  You need a collection of sql (created with CREATE TYPE...):

  I'll use the predefined collection sys.odcivarchar2list demonstation purposes:

  SQL> var cur refcursor
  
  SQL> declare
     ret_coll       sys.odcivarchar2list;
  begin
     delete from emp
       returning ename
            bulk collect into ret_coll;
  
     open :cur for select * from table (ret_coll);
  end;

• Potential problems with bulk assigned DN ranges

  Nobody knows possible problems with loading up to say unassigned 100 DN at the Complutense University of MADRID (8,6) with all the parameters number of directory but not assigned to a device?

  The end of the game here is that we have a few 100 DIDs that are reserved for different reasons (diff ILA or for a client) that we loaded in the system, so they are reserved and no one is going to try and use them (the idea being someone will add a DID this description will fill and they know they need to enter a different DID).

  I can even send to the unit, but don't think it's important because they are all NEW DIDs that were never sold or announced.

  Our team of engineers seems to think that this will cause a problem such as call manager will be under heavy load constantly trying to figure out what devices attached to these DNs unassigned.  I say no because they have never been assigned to a device are are essentially a placeholder.

  This would cause a problem?

  If so - how guys do you manage your DIDs unused in call manager - it seems terribly archaic to manage a spreadsheet with unused DID we rely on the entire team through the world to update when they make changes when we have essentially a database (Manager call) here to do it for us!

  Thoughts?

  This will not cause any problems and can be performed without risk. In addition you can make the inactive DNs if you prefer.

  If I remember correctly, the part INTO the query to initialize the collection in which it will collect the data, and you gather in the collections that you are querying, you end up deleting the data out of this collection until she is interrogated.

  Not really, wise trying to collect data in a collection that you are querying.

• Problem with the Collection

  I have problems of filling of a collection.

  Hi gUS,.
  Now, run your page, it will work.
  Thank you

• problem with a collection of table

  Hello!

  I work with Flex/Java RemoteObject.

  I have been following in Java

  public class IdAndName {}

  private String userId;
  private String userName;

  }

  and the equivalent in Flex

  public class IdAndName {}
  private var _userId:String;
  private var _userName:String;

  }

  I call a Java method that returns a list < IdAndName >. I get the list in flex in the following way:

  var list:ArrayCollection = ArrayCollection (event.result);

  If the var list list of the IdAndName.

  My Question is...:

  How can I get a collection ArrayCollection in Flex with the user ID (only them and not the username?)

  Thank you

  How do you list? you can fix your list in java or rewrite your ArrayCollection in flex like this collection:

  var list:ArrayCollection = ArrayCollection (event.result);

  var fitness sale: collection ArrayCollection = new ArrayCollection();

  for (var i: int = 0; i

  reList.addItem ((list.getItemAt (i) as array) [0]);     If the user ID is initially

  }

  In case you missed it: all tags have disappeared and that the actual data remained. If I change the type of column to Column Standard in the report, the same thing is happening on the page.
  
  My findings to date are:
  -Tags are present in the column, as it is sort of the column display in text type is smart enough to display the data correctly.
  -It seems that this has something to do with the character encoding, but I don't know how to fix it. I tried to use the convert() function but no luck.
  
  Any ideas?
  
  Thank you

  Hi Luis,.

  It is not something as simple that the attribute "Strip HTML" report, is it?
  (ie - change no.)

• Problem with a collection

  I've defined in a package:
  
  TYPE TIPO_TABLA_CTRL_SIT IS TABLE OF THE IGIC_DECE_400_CTRL_SIT % ROWTYPE INDEX BY PLS_INTEGER;
  
  TABLA_CTRL_SIT TIPO_TABLA_CTRL_SIT;
  
  
  And in a feature...
  
  function COUNT_CTRL_SIT (p_TABLA_CTRL_SIT IN TIPO_TABLA_CTRL_SIT) RETURN NUMBER IS
  v_reg IGIC_DECE_400_CTRL_SIT % ROWTYPE;
  
  Start
  
  -Inicializacion THE DECLARACION REAL SITUATIONS
  v_reg: = p_TABLA_CTRL_SIT.first;
  
  END;
  
  Why the following error occurred when compiling?
  
  "Error: PLS 00382: el type of the expression are no correcto.
  
  Translation:
  
  "Error: PLS-00382: wrong type in the expression.
  
  Why I can't get the first item in the collection?
  
  Thanks in advance.

  Hello

  FIRST returns the index number of the first (smaller) of your collection, in this case a PLS_INTEGER.

  So I think that you need

  v_reg:= p_TABLA_CTRL_SIT(p_TABLA_CTRL_SIT.first);

• Problem with a collection empty

  When a process is running
  
  BECAUSE me IN g_tabla_situacion. FIRST... g_tabla_situacion. LAST
  LOOP
  .....
  END LOOP;
  
  and g_tabla_situacion contains no items, ORACLE returns a
  
  "* - 6502:ORA - 06502: PL/SQL: digital error or value."
  
  How can I avoid this problem?
  
  Now, I am doing...
  
  IF (g_tabla_situacion. COUNT > 0) THEN
  
  BECAUSE me IN g_tabla_situacion. FIRST... g_tabla_situacion. LAST

  I get the error error above in the insert statement.

  I won't answer your question, but say you something else - do not do this with bulk collect. Do it in a single SQL statement.

  Stop using loops and by engaging in loops.

  Who will solve the error, makes it less likely, you get error ORA-01555, create less recovery and be more effective.

  Oh, and it does nothing useful:

  WHILE OTHERS THEN

  LIFT;

  The entire procedure should be:

  CREATE OR REPLACE PROCEDURE bulk_collect_limit (startrow IN NUMBER,endrow IN NUMBER,fetchsize IN NUMBER)
  IS
  
   l_start NUMBER;
  
  begin
  
  insert into big_table2(put a column list here for crikey's sake)

• Cursor Bulk Collect

  Hi all
  I have a doubt about cursor in block collection. Both versions work correctly.
  
  

  1st Version: 
  DECLARE
    CURSOR c1 IS (SELECT t2 FROM test10);
    TYPE typ_tbl IS TABLE OF c1%rowtype;
    v typ_tbl;
  BEGIN
    OPEN c1;  
      FETCH c1 BULK COLLECT INTO v;
    CLOSE c1;
    FOR i IN v.first..v.last
    LOOP
      DBMS_OUTPUT.PUT_LINE(v(i).t2);
    END LOOP;  
  END;
  
  2nd version: 
  DECLARE
    CURSOR c1 IS (SELECT t2 FROM test10);
    TYPE typ_tbl IS TABLE OF c1%rowtype;
    v typ_tbl;
  BEGIN
    OPEN c1;
    LOOP                                                 --Loop added
      FETCH c1 BULK COLLECT INTO v;
      EXIT WHEN c1%NOTFOUND; 
    END LOOP;
    CLOSE c1;
    FOR i IN v.first..v.last
    LOOP
      DBMS_OUTPUT.PUT_LINE(v(i).t2);
    END LOOP;  
  END;

  Is it necessary to have a loop and exit the statementwhen notfound cursor used with bulk collect?

  But in doing so, context switches will be more aint't it?

  Yes, you will need to switch between SQL and PL/SQL, which is one of the penalties you pay to use the PL/SQL when SQL is necessary (don't tell is your case here, just a generality). However, that there are compromises. Memory is a limited product, it is expensive and you do not have an infinite amount. It is not as effective to spend many thousands of records in memory and then apply to processes that together, if you bulk load a bit, process a little you avoid exhaust any given resource (CPU, memory, etc...).

  As I said, Oracle will use a fetch array of 100, instead of X, where X is the number of records your query when you use a bulk collect without LIMITS. If you had to carry 10 000 magazines across the room, do you think you would sooner do 100 at a time and do a lot of travel or find a way to carry all the 10,000 in a trip?

  If you are interested in the analysis comparative differences, set up a simple table and load 100,500,1000,10000,100000, etc... documents in it and see what look like processing times.

  For versatile use, the implicit cursor loop wins hands down for each perspective (my opinion). Yet once again, assuming that you NEED pl/sql at all.

• Using the slider for and BULK COLLECT INTO

  Hi all
  in this case we prefer to use the cursor AND the cursor with the LOOSE COLLECTION? The following contains two block this same query where used FOR the slider, the other is using COLLECT LOOSE. The task that is running better given in the existing? How do we measure performance between these two?
  
  I use the example of HR schema:

  declare
  l_start number;
  BEGIN
  l_start:= DBMS_UTILITY.get_time;
  dbms_lock.sleep(1);
  FOR employee IN (SELECT e.last_name, j.job_title FROM employees e,jobs j 
  where e.job_id=j.job_id and  e.job_id LIKE '%CLERK%' AND e.manager_id > 120 ORDER BY e.last_name)
  LOOP
    DBMS_OUTPUT.PUT_LINE ('Name = ' || employee.last_name || ', Job = ' || employee.job_title);
  END LOOP;
  DBMS_OUTPUT.put_line('total time: ' || to_char(DBMS_UTILITY.get_time - l_start) || ' hsecs');
  END;
  /
   
  declare
  l_start number;
  type rec_type is table of varchar2(20);
  name_rec rec_type;
  job_rec rec_type;
  begin
  l_start:= DBMS_UTILITY.get_time;
  dbms_lock.sleep(1);
  SELECT e.last_name, j.job_title bulk collect into name_rec,job_rec FROM employees e,jobs j 
  where e.job_id=j.job_id and  e.job_id LIKE '%CLERK%' AND e.manager_id > 120 ORDER BY e.last_name;
  for j in name_rec.first..name_rec.last loop
    DBMS_OUTPUT.PUT_LINE ('Name = ' || name_rec(j) || ', Job = ' || job_rec(j));
  END LOOP;
  DBMS_OUTPUT.put_line('total time: ' || to_char(DBMS_UTILITY.get_time - l_start) || ' hsecs');
  end;
  /

  In this code, I put a timestamp in each block, but they are useless, since they both launched virtually instantaneous...

  (1) bulk fired fresh primary use is to reduce the change of context between sql and pl sql engine.
  (2), you should always use LIMIT when it comes with bulk collect, this does not increase the load on the PGA.
  (3) and the ideal number of BOUNDARY lines is 100.

  Also if you really want to compare performance improvements between the two different approaches to sql pl try to use the package of runstats tom Kyte
