Error in initialization of multilevel nested table type
Hello
Database version: Oracle 11 g R2
I am creating a complex process I need to create complex nested table types and use them in code.
{code}
CREATE or REPLACE TYPE ws_data_compare_rt
AS AN OBJECT
(
external_web_service_id NUMBER (10),
service_code VARCHAR2 (30),
ws_bridging_id NUMBER (10),
ws_attribute_name VARCHAR2 (64).
ws_attribute_value VARCHAR2 (32767).
in_source_attribute VARCHAR2 (30),
in_source_value VARCHAR2 (32767).
comparison_rule VARCHAR2 (100)
);
CREATE or REPLACE TYPE ws_data_compare_tt IS TABLE OF THE ws_data_compare_rt;
CREATE or REPLACE TYPE ws_data_compare_master_rt
AS AN OBJECT
(
key_attribute_1 VARCHAR2 (30),
NUMBER of key_attribute1_value
key_attribute_2 VARCHAR2 (30),
NUMBER of key_attribute2_value
m_ws_data_compare_tt ws_data_compare_tt
);
/
CREATE or REPLACE TYPE ws_data_compare_master_tt IS TABLE OF THE ws_data_compare_master_rt;
{code}
The objects have been created successfully. However when I use it in my code, I need to initialize them, but I get an error for the variable of ws_data_compare_master_tt type initialization.
{code}
...
g_ws_data_compare_rt ws_data_compare_rt: = ws_data_compare_rt (NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL);
g_ws_data_compare_tt ws_data_compare_tt: = ws_data_compare_tt();
g_ws_data_compare_master_rt ws_data_compare_master_rt: = ws_data_compare_master_rt (NULL, NULL, NULL, NULL, g_ws_data_compare_tt);
g_ws_data_compare_master_tt ws_data_compare_master_tt: = ws_data_compare_master_tt();
...
{code}
I'm unable to initialize the variable g_ws_data_compare_master_tt of type ws_data_compare_master_tt that I get the below error.
For PACKAGE BODY UTL compile errors. PKG_WS_UTIL
Error: PLS-00222: no function with name 'WS_DATA_COMPARE_MASTER_TT' does exist in this scope
Line: 28
Text: g_ws_data_compare_master_tt ws_data_compare_master_tt: = ws_data_compare_master_tt();
Error: PL/SQL: ignored element
Line: 28
Text: g_ws_data_compare_master_tt ws_data_compare_master_tt: = ws_data_compare_master_tt();
Can someone help me to find out what is the problem?
Thanks in advance.
Kind regards
Natarajan
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.
Kind regards

Thank youBaptist
Get the error on tahiti, I realized this must be a common problem and is described in Metaclunk.
So in Metaclunk I get "ora-02304 imp' and came up with 1066139.6 ML.
It describes your situation.
So many times, it is very easy to solve your problems in a few minutes. I always wonder why people walk immediately into shock and horror and nothing to do when they hit a mistake.----

Format an array of multilevel nested table object in a TABLE
DB: Oracle 11 g 2
Platform: client windows 7
Hello
I have a table of multilevel nested table object.
{code}
CREATE OR REPLACE TYPE OBJ_1 AS OBJECT)
NUMBER of col_1,
col_2 VARCHAR2 (56),
col_3 VARCHAR2 (256)
);
CREATE OR REPLACE TYPE ARR_1 AS TABLE OBJ_1;
CREATE OR REPLACE TYPE OBJ_2 AS OBJECT)
NUMBER of col_4
col_5 Number (15),
col_6 NUMBER (1).
col_7 NUMBER (1).
col_8 VARCHAR2 (56),
col_arr ARR_1
);
CREATE OR REPLACE TYPE ARR_2 AS TABLE OBJ_2;
{code}
I want to convert this table format - I need to feed in a program. expected release:
--------------------------------------------------------------------------------
col_4 col_5 col_6 col_7 col_8 col_1, col_2 col_3
--------------------------------------------------------------------------------
1 2 3 4 5 1 2 3
1 2 3 4 5 4 5 6
The Toad, the following query creates the output:
{code}
Select *.
table (ARR_2 (OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (1,2, '3'))),))
OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (4.5, '6')))

col_4 col_5 col_6 col_7 col_8 col_arr
--------------------------------------------------------------------
1 2 3 4 5 (DATASET)
1 2 3 4 5 (DATASET)
{code}
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'))),))
OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (4.5, '6')))
);
Error: ORA-02324: more than one column in THE subquery SELECT list
{code}
Any suggestion?
Thank you.
You just need to join another TABLE operator who breast COL_ARR:

2. Select (ARR_2)
OBJ_2 3 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (1,2, '3')));

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

Oracle 9 error: insert into temp-table collection (nested table)
Hello everyone
I have an urgent problem. I have a package which has been developed against 10g but must now be deployed on 9i as well. I don't use 10 g - features and packages compile well on 9.
Somehow, I get the following runtime error: failed execution: ORA-22905: cannot access the rows of a no nested table item.
The Code I use to the particular line is
insert into tmp_report_calculation (select from table (calculations)); *
tmp_report_calculation is a temporary table and calculations holds a collection type that is a nested table. I do not understand why the error is complaining about "No nested table. Less than 10g everything run took place.
Can someone help me out here? Furthermore, it is important that I put the results in this temp-table (since I can't use the multiset on Oracle 9)
concerning
-Marc
Try
insert into tmp_report_calculation (select * from table(cast(calculations as your_collection_type)));
replace"your_collection_type" with your name in the actual collection of course...

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.

Pre-defined types of Oracle nested table
Hello
I am in the Internet search and could not find one of the pre-defined types of nested table in Oracle. For example: a type that can contain strings. Can anyone put here a few names of this type?create table mytable (id integer, theList sys.odcivarchar2list); insert into mytable (id, thelist) values ( 1, sys.odcivarchar2list('a','b','c'));

create table as a table with nested column type
On my Oracle DB (11.1), I have a table with a nested as a column type (and it is a partitioned table).
Now I need to copy partitions in a second table, and I use swap partition for it (with a table that is not partitioned as a table in step).
But there is a problem, because as the ordinary as sql ddl:
does not work when there is a table nested within a column type.create table table1_stage as select * from table1 where 1=2;
Is it possible easy to copy its structure (and to create the table that is not partitioned, so I suppose that no dbms_metadata package would help)?
Kind regards...>
does not work when there is a table nested within a column type.
>Will work indeed.

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,
NKMMaldini 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 PL/SQL procedure successfully completed.

Or better use bulk collect:
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 select book_obj(name,author,abstract) bulk collect into bookset from book; for i in 1..bookset.count loop --> Now Looping two times. dbms_output.put_line(' name > '||bookset(i).name); 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 PL/SQL procedure successfully completed.

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 orBULK
COLLECT
clause).With the help of documents and Collections of PL/SQL

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?
Run the scripts below to reproduce the problem and be sure to update this post if more information is required.

-Note that this type contains the table T_MDQ_DETAIL type:
CREATE OR REPLACE TYPE MDQ_PARENT FORCE AS OBJECT (NUMBER MDQ_ID, MDQ_DETAILS T_MDQ_DETAIL);
- Then I create two equal nested tables
CREATE THE NESTED TABLE AS MDQ_PR_OLD STORE MDQ_DETAILS MDQ_PARENT MDQ_OLD TABLE.
CREATE THE NESTED TABLE AS MDQ_PR_NEW STORE MDQ_DETAILS MDQ_PARENT MDQ_NEW TABLE.
-Insert test data in the nested tables
Insert into MDQ_OLD (MDQ_ID, MDQ_DETAILS) Values (1, T_MDQ_DETAIL (MDQ_DETAIL(1,'desc1')));
Insert into MDQ_NEW (MDQ_ID, MDQ_DETAILS) Values (2, T_MDQ_DETAIL (MDQ_DETAIL(1,'desc1')));

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.

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.).

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
