• Question simple quue PL/SQL nested tables

  Hello, my question is about nested tables. Suppose I have a nested table:
  Int_array ARRAY TYPE IS INT;
  v_int_array int_array;
  
  Is there a built in function for me to v_int_array for a specific integer search value?

• Question about the nested Table

  I created a table nested in the database type.

  CREATE TYPE TT1 IS TABLE OF THE VARCHAR2 (100);

  If I use this collection in my procedure and fill it with values, these values are stored in the tablespace/data files or cache. I'm asking is because I want to fill the collection with a lot of documents and collections are stored in memory and the comprehensive data set will explode memory told me.
  

  You mention a procedure so I guess that we are talking about a nested table defined in and complemented by a PL/SQL block.  If so, these data are stored in the PGA.  You should be a good idea on the amount of data you have in the PL/SQL collections at any time in time, because the PGA memory is a relatively rare commodity.

  If we are talking of a nested table that corresponds to a column in a normal organized in a heap table, these data are stored in data files and read the SGA according to the needs as all data in a heap table.

• Nested table frees the file after validation?

  Hello world

  My version of DB is

  Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi

  PL/SQL Release 10.2.0.1.0 - Production

  "CORE 10.2.0.1.0 Production."

  AMT for Linux: Version 10.2.0.1.0 - Production

  NLSRTL Version 10.2.0.1.0 - Production

  I have a question about the nested table. I am writing a code to change the data type for a column varchar2 to date without deleting the data.

  So I thought instead of creating the table or the TWG, I will fill these data in the collection and updating of this column as null. So I'll change the data type for this column and the data that is loaded inside the collection, I'll shoot back as it is.

  The collection is formed, the data are updated with the null value and data type of the column is updated as well. But when I'm trying to load the data in collection, it seems to be empty. Why is happening. ? Nested table depends on the statement commit?

  Please take a look at the code and suggest me something here.

  Your EXCEPTION WHILE others removes any possible EXCEPTOIN that is raised. You need to get rid of him. Or at least use RAISES at the end. And if you decide to use the collection then get the best out of him using treatment in BULK. Here is an example FORALL.

• Nested table

  When you create a table nested within a table, can I please have a description of what the STORE AS medium of instruction?
  
  Here is an example:
  
  NESTED TABLE, STORE LineItemList_ntab AS PoLine_ntab
  
  I have had a look in the documentation, but cannot find the answer to this question.

  Sound the segment of nested table name, 11 g, you can also have SECUREFICHIERS as for example you can thus encrypt, oracle doc said The Oracle database server stores data for the nested table offline from the lines of the parent table, using a table of store that is associated with the nested table column. The parent row contains a value to set unique identifier associated with a nested table instance. See http://docs.oracle.com/cd/B28359_01/server.111/b28318/schema.htm#CHDFDBGH

• Columns of the nested Table and ADF BC 11.1.2

  I think coming to a new conception of the application, including a redesign of the database. In this application, there are users who cannot change tables of production directly, but their amendments must be approved (and possibly modified) before applying them to production tables. The production tables are part of an existing system and are fairly well standardized, with a main table and several paintings of detail.
  
  So for the new design, I want to have a table intermediate, mirrored in the main table, where the user's changes are stored until they are approved and applied to the production tables. The intermediate table contains some additional columns for the user "add, change or delete", who supported the change, the date modified is requested. After you apply the change, the intermediate folder must be copied in a historic change and deleted from the staging table. In this way, the intermediate table is never a lot of data in it.
  
  Here's the question:
  I need to treat the tables in detail. I could have staged versions of each table in detail, but I thought it might be easier to manage if detail tables have been included in table nested table columns main staging area. Most of the detail tables contain only a few rows with rank of master. But ADF BC 11.1.2 can treat the nested table columns? Is it easy to use in an application?

  Hello

  and ADF Faces does support nested tables? lol so even if ADF BC would be, where would you go with this approach? Polymorphic views would be an option (think hard)?

• 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));
  /
  
  Step 2:
  CREATE or REPLACE TYPE book_table IS TABLE OF THE book_obj;
  /
  
  Step 3: CREATE TABLE book (name, varchar2 (25), varchar2 (25) author, varchar2 (4000)) abstract;
  INSERT VALUES Accountants ('Harry Potter,' 'MK', 'It's magic');
  INSERT the book VALUES ("Ramayana', 'VK', 'It is mythiology'");
  COMMIT;
  
  Step 4:
  declare
  bookset book_table;
  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
  for rec in (select * from book) loop-> now a loop twice.
  dbms_output.put_line (' name > ' |) Rec.Name);
  bookset: = bookset_t (book_t (rec.name, rec.author, rec.abstract));
  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,
  NKM

  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)
  end;
  /
  The count is 1
  The count is 0
  name > Harry Potter
  name > Ramayana
  The count is 2

      ln_cnt pls_integer;
  begin

• nested table County

  select bt.ISBN, bt.title, bt.author, bt.classmark, ct.copy#, count(s) numOnLoan
  from book_tab bt, copy_tab ct, table(ct.isSubjectOf) s

  or bt.classmark like 'S.321.45%'

  Hello I can't people seem to find all threads that answered my question.
  If I remove the County this query works
  
  each row of the copy_tab has a nested table of ref to loan_t. I want out of a column for each row that displays how many rows there are in the nested table that is how many copies is lent.
  
  I've tried a few things but none of them work! so why I am here!

  I suppose that column in ais copy_tab isSubjectOf table a nested table. If so, use:

  select  bt.ISBN,
          bt.title,
          bt.author,
          bt.classmark,
          ct.copy#,

• How to represent Nested table as variable/object in OIC

  Hi all
  
  I'm new to the BEAK.
  
  I now have the nested in my database table.
  Nested table:
  Create the type type1 as an object (name varchar2 (20));
  Create the type type2 as type1 table;
  create table table1 (varchar2 (20) col1, col2 type2) store col2 table nested as table2;
  
  Can someone help me to col2 as C structure/typedef to use it with OCIDefineObject?

  You can take a look at Chapter 11 of the Guide to the programmer of the OIC. Look at the Collections inside section. You can represent the nested as OCITable table *. In addition, you can generate a representation of the structure of your object using OTT type. Please let us know if that answers your question. In the case where you are not able to proceed please let us know.

  Thank you

• helps the update in the parameter of the nested table

  I was asked a question by a co-worker, but I couldn't help him.
  
  He got these types:

  CREATE OR REPLACE TYPE TP_COLTYPE AS OBJECT (
    parametro varchar2(30 byte),
    rango  number(12,2),
    color  varchar2(15 byte)
  )
  /
   
  CREATE OR REPLACE TYPE TP_COLTYPE_TAB AS TABLE OF TP_COLTYPE;
  /
   
  CREATE OR REPLACE TYPE TP_PARTYPE AS OBJECT (
    perfil_comercial VARCHAR2(30),
    subtendido VARCHAR2(2),
    parametros TP_COLTYPE_TAB
  )
  /

  And he wants to create a procedure that has IN OUT TP_PARTYPE parameter so that it can change the color column in all records in the table. It's his essay (which fails to compile):

  CREATE OR REPLACE PROCEDURE getColoresUmbrales(p_parametros IN OUT TP_PARTYPE) IS
      CURSOR c_partype IS SELECT parametro,rango FROM TABLE(p_parametros.parametros) FOR UPDATE; 
  BEGIN
      FOR r_partype IN c_partype LOOP
          UPDATE TABLE(p_parametros.parametros)
              SET color = getColorUmbral(p_parametros.perfil_comercial,p_parametros.subtendido,r_partype.parametro,r_partype.parametro)
           WHERE CURRENT OF c_partype;
      END LOOP;
  EXCEPTION WHEN OTHERS THEN
  
  RAISE_APPLICATION_ERROR(-20000,SQLERRM);
  
  rollback;
  
  END getColoresUmbrales;

  I don't think you use a cursor is necessary or effective, but I failed to find the right way. I don't know which version he works with, but I know that it is 10g.
  Could someone help us please?

  fsanchezherrero wrote:
  the need for a procedure is because to get the color, it is necessary to call the strored function.

  It doesn't really sound like the design needs to be changed. A nested table is to create a child table and add foreign keys and key primaries, but behind the scenes, so you lose the possibility to 'normal' updates etc. on the child table!

  Convert a standard parent-child relationship, and it will be much, much, much, much easier to deal with. No funky code required then!

• insertion in a nested table of pl/sql

  worm 10.2.0.3
  
  I know that I can do this in the example with a big collect but in the 'real' code, I have to be inserted...
  
  My question is how to insert in a nested table of pl/sql?
  

  create or replace type all_obj_obj as object(owner varchar2(30),object_name varchar2(30),object_type varchar2(30))
  /
  
  create or replace type all_obj_list as table of all_obj_obj
  /
  
  declare
   coll  all_obj_list := all_obj_list();
  begin
   insert into table(coll) select owner,object_name,object_type from all_objects;
  end;
  / 

  I know that could do a select master, object_name, object_type bulk collect in coll but I do an insert for some reason as long as I can go in... anyway to do it?

  Your "nested table" is not a "nested table" but a collection, a varable.
  Obviously so can not INSERT in a memory structure.
  Your need is not supposed, as BULK COLLECT would do the tric.
  As you cannot disclose why you ' need; for this (you do not have) and also do not mention a version, as you ' assume; PL/SQL does not ever change or everyone uses the same version, no additional help is possible.

  Hello

  My version of oracle db: 11g

  I just created a table that contains a nested multi-level table.

• 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;

  /

  Error

  • Error (6.3): PL/SQL: statement ignored
    
  • Error (6,12): PLS-00306: wrong number or types of arguments in the call to 'COUNTRIES_T '.
    
  • Error (7.3): PL/SQL: statement ignored
    
  • Error (7.32): PLS-00302: component 'COUNTRY_ID' must be declared

  Thanks in advance

  Concerning

  Muzz

  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.

  Kind regards
  Maxou
