• Function returning the tree used with the object type

  Hi guys!
  
  I'm fighting for some time now of a function that should return the tree structure of the employees. Let me clarify...
  I have a table say Manager and employees (two columns for an example)
  MANAGER_ID
  EMPLOYEE_ID
  
  Example:
  
  MAN_ID - 1; EMPLOYE_ID - 2;
  MAN_ID - 2; EMPLOYE_ID - 3;
  MAN_ID - 2; EMPLOYE_ID - 4;
  MAN_ID - 4; EMPLOYE_ID - 5
  
  The purpose of my function is back for a specified MAN_ID everyone in the tree...
  
  Example:
  
  RETURN_TREE (1) return {2,3,4,5};
  RETURN_TREE (2) returns {3,4,5};
  RETURN_TREE (4) returns {5};
  
  How to get there?
  
  With respect,

  And use BULK COLLECT or the COLLECT function to build the collection:

  create type emp_table as table of number(6);
  /
  

  DECLARE
   v_emp_list emp_table;
  BEGIN
   select cast(collect(employee_id) as emp_table)
   into v_emp_list
   from employees
   connect by prior employee_id = manager_id
   start with manager_id = :p_man_id
  
   -- or
   /*
   select employee_id
   bulk collect into v_emp_list
   from employees
   connect by prior employee_id = manager_id
   start with manager_id = :p_man_id
   */

• How to return data using the object type?

  Hello all - I have an obligation to return the values object type.

  In the same way as

  list - Plan1, Subplan1, Fund1, 2 Fund Fund 3

  list - Plan2, Subplan2, Fund2

  list - plane3, Subplan3, not funds

  
  

  To achieve this I wrote below proc but its giving as response below which is does not correspond with my requirement. Someone has an idea how to write code to get the list of funds against each plan in each line?

• How to use a collection type of variable binding to execute dynamic statement

  Hello
  
  We have a case where we copy selective data from A to B schema of schema in an oracle database. The copy is obtained using

• How to convert the column of ROW using DBMS_REDIFINITION object type column

  Hi all
  Suppose I have the following table to convert:

  create table customer as select customer_id cid, cust_first_name name, cust_address street from customers;

  I created the table based on the customers of the OE schema table, while the street column has cust_address_typ with the following attribute object type

   STATE_PROVINCE                               VARCHAR2(10)
   COUNTRY_ID                                   CHAR(2)

  I want to convert the object attribute adresse_rue in a column of RDM. Consider the following temporary table:

  CREATE TABLE INT_CUSTOMER(
  CID NUMBER,
  NAME VARCHAR2(30),
  street varchar2(100)

  First of all, I checked if the table can be redefined:

  Have you tried this one:

  BEGIN
  DBMS_REDEFINITION.START_REDEF_TABLE(
  uname => 'OE',
  orig_table => 'CUSTOMER',
  int_table => 'INT_CUSTOMER',
  col_mapping => 'CID CID, NAME NAME,"CUSTOMER".STREET.STREET_ADDRESS STREET'
  );
  END;
  

  Looking at your trace file, I claim that when you use the call above to START_REDEF_TABLE, the inner workings of this procedure will create this SQL statement:

  select CID CID, NAME NAME,"CUSTOMER".STREET.STREET_ADDRESS STREET from "OE"."CUSTOMER" "CUSTOMER"
  

  (You can prove or disprove my claim by tracing it ;-)))

  And this statement has had an alias - even if the alias is the same as the name of the table...

• Data Modeler: how to create and use the collection type

  Hello
  essentially of departure I don't understand how (for example) create and use the data based on the type of data varray type.
  
  Please notify.
  Thank you
  Andrew

  Hi André,.

  You can create new types of collection (varray/table) in two ways:
  (1) in the browser - find 'Types of data' > 'Types of Collection' node menu dropdown - there just 'create new collection type' it
  (2) in the types of data model diagram - you can create collection "some type structured" or collection of references to the it - use 'new Collection... '. "tool and click first on sight structured type and after the structured type that will contain the collection - new attribute is added to the latter and if there is none this type of collection already didn't set the new collection type are created and you can change it later.

• How to fill the value in the nested table by using the object type

  
  Hi gurus

  I created an object type and able to fill the values in it, now I want to create a nested table type of this object and fill it but looks like I'm doing something wrong, see my code below.

  Code example

  CREATE or REPLACE TYPE countries_o
  AS
  OBJECT
  (
  COUNTRY_ID TANK (2 BYTES),
  COUNTRY_NAME VARCHAR2 (40 BYTE),
  REGION_ID NUMBER);
  /

  create or replace type countries_t is table of the countries_o;

  CREATE OR REPLACE

  ABC of the PROCEDURE

  IS

  v_print countries_t; -: = arr_countries_t('01','Aus',1);

  BEGIN

  v_print: = countries_t('01','A',11);

  DBMS_OUTPUT. Put_line (v_print. COUNTRY_ID | v_print. COUNTRY_NAME | v_print. REGION_ID);

  END;

  Concerning

  Hi user,

  Here is another method that you can try-

  CREATE OR REPLACE

  ABC of the PROCEDURE

  IS

  v_print countries_t: = countries_t (countries_o('01','A',11));

  BEGIN

  DBMS_OUTPUT. Put_line (v_print (1).) COUNTRY_ID | v_print (1). COUNTRY_NAME | v_print (1). REGION_ID); -you're accessinf the first element of the nested table, which in turn points to the object.

  END;

  In the sections of the declaration you have assigned values to the nested table.

• return used with recursive with type object tree

  TNS for 32-bit Windows: Version 11.2.0.1.0 - Production
  NLSRTL Version 11.2.0.1.0 - Production

  There was just a post called employee return tree with the object type, and there were several responses.
  I tried to wrap my brain around the recursive with and I was wondering how to implement it for this problem
  
  Basically, the post was something like that.

  CREATE TABLE employees
  AS
     SELECT 1 mgr_id, 2 emp_id FROM DUAL
     UNION
     SELECT 2, 3 FROM DUAL
     UNION 
     SELECT 3, 4 FROM DUAL
     UNION
     SELECT 4, 5 FROM DUAL;

  and he wanted to

  MGR_ID     GET_EMPS(MGR_ID)
  1     2,3,4,5
  2     3,4,5
  3     4,5
  4     5

  as mentioned, it has several solutions were however I was and wrote a recursive function
  to get the answer. that seems to work
  

  CREATE OR REPLACE FUNCTION get_emps (p_mgr employees.mgr_id%TYPE)
     RETURN VARCHAR2
  IS
     v_mgr    employees.mgr_id%TYPE;
     v_emp    employees.emp_id%type;
     v_emps   VARCHAR2 (200);
  BEGIN
     v_mgr := p_mgr;
     LOOP
        SELECT emp_id
          INTO  v_emp
          FROM employees
         WHERE mgr_id = v_mgr;
  
        v_emps := v_emps||','||v_emp;
        v_mgr := v_emp;
     END LOOP;
    exception when no_data_found then
    return  substr(v_emps,2);
      END;

  now, I would like to convert a recursive with my function, but I can't quite understand.
  
  Here's what I have so far but I'm still not close.
  

  WITH emp1 
   (mgr_id, emp_id, emp_ids)
   AS  
   ( SELECT mgr_id  , to_char( emp_id), to_char(emp_id)  from employees  WHERE mgr_id = 1
   UNION /* my internet filter will not alllow me to post this statement */ALL
     SELECT emp2.mgr_id,  to_char(emp2.emp_id), to_char(emp1.emp_id)||','||to_char(emp2.emp_id)
     FROM employees emp2 JOIN emp1 ON (emp2.mgr_id = emp1.emp_id)
   )
   select * from emp1

  Sorry for the comment here we have a weird filter on our internet that does not allow me to view the word a union |

  Hello

  You're so close! You just need a character more:

  WITH emp1
   (mgr_id, emp_id, emp_ids)
   AS
   (
       SELECT  mgr_id
       ,     TO_CHAR (emp_id)
       ,     TO_CHAR (emp_id)
       FROM     employees
       WHERE     mgr_id        = 1
      UNION ALL
           SELECT  emp2.mgr_id
       ,     TO_CHAR (emp2.emp_id)
       ,     TO_CHAR (emp1.emp_ids) || ',' || TO_CHAR (emp2.emp_id)
  --                        ^
  --                        s added above
       FROM     employees emp2
       JOIN             emp1 ON (emp2.mgr_id = emp1.emp_id)

• Filter for a specific value object type

  I would like to know if the documents loaded on an object type can be interrogated for a specific value. For ex, I wanted to fetch all the records of the emp and load it into an object. I wanted to ask the object out of the loop to query for a specific deptno. I understand a query simpe SQL would be much faster in the scenario below, but the report itself used in our system uses several tables and some of them have millions of records from different sources as accounts suppliers, accounts receivable, accounting, etc. and they are treated differently for each source before that the result will be published the report. I took the table emp for example and wanted to know if the type of object can be queried for a specific column outside the loop.

  DECLARE

  CURSOR cur_emp IS SELECT * FROM EMP;

  TYPE emp_obj IS TABLE OF cur_emp % ROWTYPE INDEX BY PLS_INTEGER;

  l_emp_tab emp_obj;

  BEGIN

  OPEN cur_emp.

  LOOP

  Get the cur_emp COLLECT LOOSE l_emp_tab LIMIT 1000;

  EXIT WHEN l_emp_tab.count = 0;

  BECAUSE me IN 1.l_emp_tab.count

  Loop

  dbms_output.put_line (' Ename:' | l_emp_tab (i) .ename |', Deptno:' | .deptno l_emp_tab (i));

  END LOOP;

  END LOOP;

  -Can I ask specific employee to a deptno outside the loop FOR without using a temporary table

  -something like "SELECT * FROM TABLE (type_name) WHERE DEPTNO = x_Deptno.

  END;

  /

  In a collection of table selection is not effective, there are better ways to do it.

  Why not create a view?

  create view...

  Select * from source1 Union all the

  Select * from source2 Union all the

  Select * from source3

  -or-

  Using ref cursor return... clause, so you can make conditional cursors

  If somecondition then

  Open the NEWS for

  Select * source1;

  on the other

• Nested table of object type have only one record all the time

  Hi all
  
  I have a question regarding the storage of multiple records in a nested Table that is of type OBJECT.
  
  The program below that I wrote for the test and during the test, I was able to store only the last record in the nested Table.
  
  Please let me know what I did wrong here.
  
  Step 1:
  CREATE or REPLACE TYPE book_obj AS OBJECT (name varchar2 (25), author varchar2 (25), abstract varchar2 (4000));

  INSERT VALUES Accountants ('Harry Potter,' 'MK', 'It's magic');
  INSERT the book VALUES ("Ramayana', 'VK', 'It is mythiology'");
  COMMIT;
  
  Step 4:
  declare

  ln_cnt pls_integer;
  Start
  bookset: = book_table (book_obj ('madhu', 'kongara', 'sudhan'));
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see COUNT = 1
  bookset: = bookset_t(); -> Assignment to NULL.
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see County 0

  end loop;
  dbms_output.put_line (' the number is ' | bookset.) (Count); -> I can see COUNT = 1 (why?)
  END;
  
  I looped twice to fill two records in the TABLE IMBRIQUEE OF TYPE OBJECT. But when I see the Count I get only 1 and the data is also having the last record.
  
  Can you get it someone please let me know how to fill out the table nested with all records. Tell me where I am wrong.
  
  Very much appreciate your help here.
  
  Thank you and best regards,

  Maldini says:
  dbms_output.put_line (' the number is ' | bookset.) (Count); -->, I can see COUNT = 1 (why?)

  Because instead of add to bookset collectionto set (ergo replacement) it a collection containing recovered book. Use:

  declare
      bookset book_table;
      ln_cnt pls_integer;
  begin
      bookset := book_table(book_obj('madhu','kongara','sudhan'));
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1
      bookset := book_table(); --> Assigning back to NULL.
      dbms_output.put_line('The count is '||bookset.count); --> I can see count as 0
      for rec in (select * from book) loop --> Now Looping two times.
        dbms_output.put_line(' name > '||rec.name);
        bookset.extend;
        bookset(bookset.count) := book_obj(rec.name, rec.author, rec.abstract);
      end loop;
      dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1 (why)

• Casting of object type to aid to more specific

  Hello

  I'm bit stuck in the legacies of the class in my current project. I implement a zero-coupling messaging architecture that uses variant tables to store objects to be cast to sample.

  The good news: it works in general, little we take a peek at some photos

  I tried the script of coulee before using an example that works as expected.

  

  Shows probe resulting:

  

  The Message of abstract [14] is cast to the more specific Message for the controller test [15], [9]

  Now, this implementation with the variants table, change things unfrotunately:

  

  The only thing that apparently changes is, as the class to be cast to a return value of a Subvi (actually reading the table variant) [12].

  As shown in the probe that the casting does not work this time... There is also no error on the terminal error.

  I have to admit, I'm quite confused... especially because in another class this exact methodiolgy works...

  Any thoughts?

  See you soon

  Oli

  Cast throws more specific to the type of object shown on the thread in the IDE, regardless of the type of the actual object passing along this thread (i.e. type of YARN and not DATA type).

  I bet that your wire to the Center terminal of the 'to more specific' is a son of the same type as the object you are trying to change but actually a more specific object.  The 'Cast to more specific"is a compiling decision, not a decision of execution. As such it takes the type of thread, not the object type for the casting.

  Look at the names on the left of your probes, they are all the same in the example below (all wires are nominally of the same type).  It's the onfo LV casting (assuming the names corresponding to the nominal type of the thread) not use content REAL of the wire.

  PS to make things clearer, give each hierarchy in your legacy a different aspect of wire.

• Using bulk collect into with assistance from the limit to avoid the TEMP tablespace error run out?

  Hi all

  I want to know if using bulk collect into limit will help to avoid the TEMP tablespace error run out.

  We use Oracle 11 g R1.

  I am assigned to a task of creating journal facilitated for all tables in a query of the APEX.

  I create procedures to execute some sql statements to create a DEC (Create table select), and then fires on these tables.

  We have about three tables with more than 26 million records.

  It seems very well running until we reached a table with more than 15 million record, we got an error says that Miss tablespace TEMP.

  I googled on this topic and retrieve the tips:

  Use NO LOG

  Parallel use

  BULK COLLECT INTO limited

  However, the questions for those above usually short-term memory rather than running out of TEMPORARY tablespace.

  I'm just a junior developer and does not have dealed with table more than 10 million documents at a time like this before.

  The database support is outsourced. If we try to keep it as minimal contact with the DBA as possible. My Manager asked me to find a solution without asking the administrator to extend the TEMP tablespace.

  I wrote a few BULK COLLECT INTO to insert about 300,000 like once on the development environment. It seems.

  But the code works only against a 000 4000 table of records. I am trying to add more data into the Test table, but yet again, we lack the tablespace on DEV (this time, it's a step a TEMP data)

  I'll give it a go against the table of 26 million records on the Production of this weekend. I just want to know if it is worth trying.

  Thanks for reading this.

  I really need check that you did not have the sizes of huge line (like several K by rank), they are not too bad at all, which is good!

  A good rule of thumb to maximize the amount of limit clause, is to see how much memory you can afford to consume in the PGA (to avoid the number of calls to the extraction and forall section and therefore the context switches) and adjust the limit to be as close to that amount as possible.

  Use the routines below to check at what threshold value would be better suited for your system because it depends on your memory allocation and CPU consumption.  Flexibility, based on your limits of PGA, as lines of length vary, but this method will get a good order of magnitude.

  CREATE OR REPLACE PROCEDURE show_pga_memory (context_in IN VARCHAR2 DEFAULT NULL)

  IS

  l_memory NUMBER;

  BEGIN

  SELECT st. VALUE

  IN l_memory

  SYS.v_$ session se, SYS.v_$ sesstat st, SYS.v_$ statname nm

  WHERE se.audsid = USERENV ('SESSIONID')

  AND st.statistic # nm.statistic = #.

  AND themselves. SID = st. SID

  AND nm.NAME = 'pga session in memory. "

  Dbms_output.put_line (CASE

  WHEN context_in IS NULL

  THEN NULL

  ELSE context_in | ' - '

  END

  || 'Used in the session PGA memory ='

  || To_char (l_memory)

  );

  END show_pga_memory;

  DECLARE

  PROCEDURE fetch_all_rows (limit_in IN PLS_INTEGER)

  IS

  CURSOR source_cur

  IS

  SELECT *.

  FROM YOUR_TABLE;

  TYPE source_aat IS TABLE OF source_cur % ROWTYPE

  INDEX BY PLS_INTEGER;

  l_source source_aat;

  l_start PLS_INTEGER;

  l_end PLS_INTEGER;

  BEGIN

  DBMS_SESSION.free_unused_user_memory;

  show_pga_memory (limit_in |) "- BEFORE"); "."

  l_start: = DBMS_UTILITY.get_cpu_time;

  OPEN source_cur.

  LOOP

  EXTRACTION source_cur

  LOOSE COLLECTION l_source LIMITED limit_in;

  WHEN l_source EXIT. COUNT = 0;

  END LOOP;

  CLOSE Source_cur;

  l_end: = DBMS_UTILITY.get_cpu_time;

  Dbms_output.put_line (' elapsed time CPU for limit of ')

  || limit_in

  || ' = '

  || To_char (l_end - l_start)

  );

  show_pga_memory (limit_in |) "- AFTER");

  END fetch_all_rows;

  BEGIN

  Is there a way I can just use pl/sql block using bulk collect?

  Thank you very much

  Hi 5181139

  As Paulzip and Jarkko Turpeinen have pointed out, you could do it using only SQL...

  This is a course using COLLECT in BULK:

  DECLARE
     blimit CONSTANT PLS_INTEGER := 500;
     CURSOR curupdate1 IS
        SELECT MF_TJ.UID_LO
        FROM   MF_TJ
        WHERE  MF_TJ.DTYP IN (SELECT CD
                              FROM MF_DOC_TYPE
                              WHERE MF_DOC_TYPE.DTYP_CAT = 'xx')
        AND MF_TJ.LINE_TYP IS NULL;
     TYPE c_arr IS TABLE OF curupdate1%ROWTYPE;
     c_rows c_arr;
  BEGIN
     OPEN curupdate1;
     LOOP
        FETCH curupdate1 BULK COLLECT INTO c_rows LIMIT blimit;
        FORALL i IN c_rows.FIRST..c_rows.LAST
           UPDATE MF_TJ
           SET    MF_TJ.LINE_TYP = 'NR'
           WHERE  MF_TJ.UID_LO = c_rows(i).uid_lo;
  
        FORALL i IN c_rows.FIRST..c_rows.LAST
           UPDATE MF_AJ
           SET    MF_AJ.LINE_TYP = 'NR'
           WHERE MF_AJ.TJ_UID_LO = c_rows(i).uid_lo;

• Bulk collect / forall type what collection?

  Hi I am trying to speed up the query below using bulk collect / forall:

  SELECT h.cust_order_no AS custord, l.shipment_set AS Tess
  Info.tlp_out_messaging_hdr h, info.tlp_out_messaging_lin l
  WHERE h.message_id = l.message_id
  AND h.contract = '12384'
  AND l.shipment_set IS NOT NULL
  AND h.cust_order_no IS NOT NULL
  H.cust_order_no GROUP, l.shipment_set

  I would like to get the 2 selected fields above in a new table as quickly as possible, but I'm pretty new to Oracle and I find it hard to sort out the best way to do it. The query below is not working (no doubt there are many issues), but I hope that's sufficiently developed, shows the sort of thing, I am trying to achieve:

  DECLARE
  TYPE xcustord IS TABLE OF THE info.tlp_out_messaging_hdr.cust_order_no%TYPE;
  TYPE xsset IS TABLE OF THE info.tlp_out_messaging_lin.shipment_set%TYPE;
  TYPE xarray IS the TABLE OF tp_a1_tab % rowtype INDEX DIRECTORY.
  v_xarray xarray;
  v_xcustord xcustord;
  v_xsset xsset;
  CUR CURSOR IS
  SELECT h.cust_order_no AS custord, l.shipment_set AS Tess
  Info.tlp_out_messaging_hdr h, info.tlp_out_messaging_lin l
  WHERE h.message_id = l.message_id
  AND h.contract = '1111'
  AND l.shipment_set IS NOT NULL
  AND h.cust_order_no IS NOT NULL;
  BEGIN
  Heart OPEN;
  LOOP
  News FETCH
  LOOSE COLLECTION v_xarray LIMIT 10000;
  WHEN v_xcustord EXIT. COUNT() = 0;
  FORALL I IN 1... v_xarray. COUNTY
  INSERT INTO TP_A1_TAB (cust_order_no, shipment_set)
  VALUES (v_xarray (i) .cust_order_no, v_xarray (i) .shipment_set);
  commit;
  END LOOP;
  CLOSE cur;
  END;

  I'm running on Oracle 9i release 2.

  Short-term solution may be to a world point of view. Pay once per hour for the slow and complex query execution. Materialize the results in a table (with clues in support of queries on the materialized view).

  Good solution - analysis logic and SQL, determine what he does, how he does it and then figure out how this can be improved.

  Ripping separate cursors in SQL and PL/SQL code injection to stick together, are a great way to make performance even worse.
