• 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;

  /

  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

  Where (DATASET) is the inner nested table. So I thought I'd add a level to "function table" will do the job, but NO, mistake.

  {code}

  Select * from table)

  Select *.

  table (ARR_2 (OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (1,2, '3'))),))

  Ah, I found the problem on my own. It was because of a bad statement similarly variable g_ws_data_compare_master_tt in a table in the specification of the package that was trouble. However I wonder the error returned Oracle was not fully exposed.

• Compare the content of two equal nested tables

  I'm working on a black box test where I compare the contents of two structurally equal tables before and after executing a script of some. My two tables, MDQ_OLD and MDQ_NEW, are filled with the data in two separate operations.

  The two tables, I'll compare are nested, as you can see in the CREATE TABLE scripts below.

  I tried to use the less-operator sign, but without success.

  I also tried to select data in a type that is % ROWTYPE to my nested tables, but it does not work as well (see the below script in this post).

  Can you please help me on this problem on how to compare the content of two nested tables?

• 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."

  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.

• What is the preferred means of data transmission as a type of record between the nested table of pl/sql program or an associative array

  What is the preferred means of data transmission in the associative array of the nested table record vs

  Choose between Nested Tables and associative arrays

  The two nested tables and associative arrays (formerly index - by tables) use similar index notation, but they have different characteristics when it comes to persistence and ease of passing parameters.

  Nested tables can be stored in a column of data, but can of associative arrays. Nested tables can simplify the SQL operations where you would normally join a single-column table with a larger table.

  Associative arrays are appropriate for relatively small lookup tables where the collection can be constructed in memory whenever a procedure is called or a package is initialized. They are good for the collection of the information volume is unknown beforehand, because there is no fixed limit on their size. Their index values are more flexible, as associative array indices can be negative, can be no sequential and can use values of string instead of numbers.

  PL/SQL automatically converts between the bays of the host and the associative arrays that use values of digital keys. The most effective way to move the collections to and from the database server is to implement data values in associative arrays, and then use these associative arrays with erections in bulk (the FORALL statement or BULK COLLECT clause).

• 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.

• How to remove the space between the nested tables.

  I'm not able to line up the parts of the nested table side by side without a big white space. You are using Mac OS 10, DW CS 6. link to page

  Thank you very much. J

  It's just terribly, terribly code.

  You should not be using heights or split cells in a table.

  The cause of your 'current' issue is through the establishment of a height on yourcell:

• How to get Nested table function

  Hi friends,

  In a package, I created a nested table type name Varchar2 EmployeeCodeList.

  Then, I created a function whose return type is EmployeeCodeList. But I don't get how to get the values of this function?

  TYPE EmployeeCodeList IS TABLE OF THE VARCHAR2 (30);

  FUNCTION GenerateRandomEcF (Ec_length NUMBER, NumberOfEmp NUMBER)

  < < the function code > >

  	RETURN v_RandomEmpCodes;

  END GenerateRandomEcF;

  PROCEDURE GenerateEmpFile (NumberOfEmp NUMBER, Start_SN NUMBER, EmpValue NUMBER, VARCHAR2, VARCHAR2, Ec_length NUMBER EmpGroup HireDate) IS

  v_Filename VARCHAR2 (40);

  v_EmployeeCodes EmployeeCodeList;

  v_EmpBatchF UTL_FILE. TYPE_DE_FICHIER;

  BEGIN

  v_Filename: = 'EMPLOYEE_BATCH_ ' | TO_CHAR (SYSTIMESTAMP, 'YYYYMMDD_HHMISS'): '. DAT';

  v_EmployeeCodes: = EmployeeCodeList (NumberOfEmp);

  v_EmployeeCodes: = SELECT * FROM TABLE (GenerateRandomAcF (Ac_length, NumberOfVoucher));

  v_EmpBatchF: = UTL_FILE. FOPEN ('EXT_VOUCHER_DIR', v_Filename, 'W');

  IF UTL_FILE.IS_OPEN (v_EmpBatchF) THEN

  FOR i IN 1.NumberOfVoucher LOOP

  UTL_FILE. Put_line (v_EmpBatchF, v_EmployeeCodes (i) |) ',' || Start_SN + (i-1). «, » || EmpValue | «, » || HireDate. «, » || EmpGroup);

  END LOOP;

  END IF;

  END GenerateEmpFile;

  How the line highlighted code above must be written so that I can get value of function in a variable of the same type of nested table.

  If you use the second approach, I mean

  56 v_EmployeeCodes: = GenerateRandomAcF (Ac_length, NumberOfEmployee);

  then the collection must be initialized using the constructor method. Change line 33.48 as number below

  33 v_RandomEmployeeCodes EmployeeCodeList: = EmployeeCodeList();

  48 v_EmployeeCodes EmployeeCodeList: = EmployeeCodeList();

  This is because when you use BULK COLLECT, Oracle automatically populates the collection without initialization. But if you do not COLLECT in BULK, then the collection must be initialized before filling / extending. Otherwise, you will get error of REFERENCE to the COLLECTION that is not INITIALIZED. So this should be the code, you should use. When you do not select... INTO, you might well declare the function is private and it is not necessary to declare in the package specification.

• Inserting data in the nested table

  I explore the differences between the OBJECT and RECORD.

  As I'm still learning, I found that both are structures which essentially brings together different elements of types of different data or columns of data types, one is used in SQL and other is used in PL/SQL, please correct me if I'm wrong in my understanding.

  Below, I am trying to insert data into an array of type object, but I can't can you please help.

  CREATE OR REPLACE type sam as OBJECT
  (
  v1 NUMBER,
  v2 VARCHAR2(20 CHAR)
  );
  
  ---Nested Table---
  create or replace type t_sam as table of sam;
  
  --Inserting data----
  insert into table(t_sam) values(sam(10,'Dsouza'));

  So the only purpose of the equivalent concept of SQL types of nested tables is to use one of the data types when you define an actual table?

  So-you can certainly use more that a simple "set an actual table. (I'm fairly certain that you can pass a table nested within a procedure, for example - try it, though - I'm not 100% sure on that - it just 'logic'.) If you can define a type, you can use it, pass it around, whatever.).

  Ariean wrote:

  And this nested table could be a record in SQL or object in PLSQL or simple data type (varchar number, etc.)?

  Nested tables are just like any other type of custom data. You can create a nested table of other types of data. You can create a custom of nested tables data type.

  Stupidly, he could become... uh, stupid O_0

  CREATE TYPE o_myobj1 AS object ( id1   number, cdate1  date );
  
  CREATE TYPE t_mytype1 AS table of o_myobj1;
  
  CREATE TYPE o_myobj2 AS object ( id2   number,  dumb  t_mytype1 );
  
  CREATE TYPE t_dumber AS table of o_myobj2;
  

  O_0

  OK, my brain is starting to hurt - I hope you get the idea
