Unable to export nested tables and vaarys

Hai
How to export nested tables and varrays in oracle 8i (8.1.6) .When exporting nested tables and varrays not exporting .What is the advantage use of nested tables and varrays
Thanks in advance

Hello,
I think that with such a new release you should use DataPump (expdp/impdb) to
export Tables.
For exporting a complete Schema you may use the following syntax:
expdp {color:red}+user+{color}/{color:red}+password+{color} PARFILE=pfexport.txt_With pfexport.txt as bellow:_
SCHEMAS={color:red}+schema_name+{color}
FLASHBACK_TIME="TO_TIMESTAMP(to_char(SYSDATE,'DD-MM-YYYY HH24:MI:SS'),'DD-MM-YYYY HH24:MI:SS')"
CONTENT=ALL
DIRECTORY=EXP_DIR
DUMPFILE={color:red}+dump_file_name+{color}
LOGFILE={color:red}+log_file_name+{color}Then, in this example, you'll get the "dump file" and the "log file" into the EXP_DIR Oracle directory (if it exists).
You can check your Oracle Directories with the following query:
select * from dba_directories;Then, you can use one of these Directories or create a new one with the following statement
CREATE OR REPLACE DIRECTORY {color:red}+directory_name+{color} AS '{color:red}+directory_path+{color}';
GRANT READ,WRITE ON DIRECTORY {color:red}+directory_name+{color} TO {color:red}+user_name+{color};Hope it can help,
Best regards,
Jean-Valentin

Nested Tables and Advanced Queues- Please Help.

How do i work with NestedTable type and Advanced Queue.
I have done the following
I have Oracle 8.1.7 enterprise edition.
create type myType as TABLE OF varchar(32);
create type myObject as OBJECT (
id int,
myt myType);
DECLARE
BEGIN
dbms_aqadm.create_queue_table(
queue_table => 'my_queue_table',
multiple_consumers => TRUE,
queue_payload_type => 'myObject',
compatible => '8.1.3'
END;
The Nested Table and Object are created successfully.
but the queue is not created.
I get the following message.
DECLARE
ERROR at line 1:
ORA-22913: must specify table name for nested table column or
attribute
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 2012
ORA-06512: at "SYS.DBMS_AQADM", line 55
ORA-06512: at line 3
I know how to specify the nested table storage clause for
create table statement, but there is no provision for
it in the create_queue_table procedure.
Any help will be greately appriciated.
i have already created and tested aqs with simple data types,
also i have created simple tables with nested table type
elements.
but the combo of Nested tables and AQ is not working.
thanks in advance.

Hi Francois. Thank you very much for your reply, but it seems that i still get errors. So let me tell what i have done.
As you suggested me: i have done a block based on a sub-query for the nested-table:
'select courses from department where name= :department.name'.
In the master block(department) i have the when-new-record-instance trigger:
Declare
LC$Req varchar2(256);
Begin
LC$Req := '(select ns.courses from table
( select courses from department where name = ''' || :DEPARTMENT.name || ''' ) ns )';
Go_block('block11');
Clear_Block ;
Set_Block_Property( 'block11', QUERY_DATA_SOURCE_NAME, LC$Req ) ;
Execute_query ;
End ;
Now the errors i receive, this time in the runtime mode are:
- FRM-41380: Cannot set the blocks query data source
-FRM-41003: This function cannot be performed here.
Since it seems that you know how to work with the nested table i would really appreaciate your help. I am new in the nested table and if you could give an ex with my tables it would be great.
Thank you in advance.

Using nested tables and varrays in Forms/Reports6i

Hi! Could anybody give practical examples of applications based on nested tables and varrays in Forms/Reports6i.
The possible schema of building user interface and so on.
Thank you.

Hi,
Varrays and nested tables are not supported within Forms6i and Reports6i. This means tare is no way to use it.

Nested Tables and Forms 9i-please help

Hi
i have the folowing example of a nested table:
CREATE TYPE CourseList AS TABLE OF VARCHAR2(10) -- define TABLE type
CREATE TYPE Student AS OBJECT ( -- create object
id_num INTEGER(4),
name VARCHAR2(25),
address VARCHAR2(35),
status CHAR(2),
courses CourseList) -- declare nested table as attribute
CREATE TYPE Course AS OBJECT (
course_no NUMBER(4),
title VARCHAR2(35),
credits NUMBER(1));
CREATE TYPE CourseList AS TABLE OF Course;
CREATE TABLE department (name VARCHAR2(20),
director VARCHAR2(20),
office VARCHAR2(20),
courses CourseList)
NESTED TABLE courses STORE AS courses_tab;
In Forms i have created a data block based on table department and for managing the nested table courses_tab i found out that i should use a stored procedure:
PROCEDURE procedure_nest (c_c out courses_tab%rowtype) IS
c_c courselist;
BEGIN
select c.name, c.director,office into :department.name, :department.director,
:department.office from department c , table
(select n.courses from department n where c.name =n.name and rownum<=1);
END;
compil error:
error 999 at line 1, column 35
implemntation restriction (may be temporary) ADT or schema level
collection not supported at client side with non-OCI mode.
i really would like to know what shall i do to use and manage the nested table in forms.
Thank you very much

Nested tables and varray

hi friends,
i have a question:
why do we use nested tables and varrays?

Read the following and try to understand the examples. Try to relate them to various situations or scenarios where you can implement them. You will understand the benefits.

Not unless you provide the code you are actually using.
There is no definition of 'p_code_result' in your post and you say you 'trying to select data from d_table' but there is no code that loads 'd_table' in what you posted.
And the SELECT query you posted actuall selects from an object named 'l_loop_idag_code_table1' which isn't mentioned in your code.
Post the actual code you are using and all of the structures being used.
Also explain why you even need to use nested tables and PL/SQL for whatever it is you are really doing.

Well you are doing almost everything wrong that could be done wrong.
Here is code that works to insert data into your table (the procedure isn't even needed).
declare
p_sl_num NUMBER := 1001;
p_description VARCHAR2(50) := 'Testing Val1';
inval1 test_type1 := test_type1();
inval2 test_type2 := test_type2();
begin
inval1.extend();
inval1(1) := test_object1('testx1', 'testx2', 'testx3');
inval2.extend();
inval2(1) := test_object2('testy1', 'testy2', 'testy3');
INSERT INTO test_object_tpe
sl_num,
description,
main_val1,
main_val2
VALUES
(p_sl_num, p_description, inval1, inval2);
commit;
end;
/See Example 5-15 Referencing a Nested Table Element in Chap 5 Using PL/SQL Collections and Records in the PL/SQL doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/collections.htm#CJABEBEA
1. You don't even need the procedure since all it does is a simple INSERT into the table which you can do directly (see my code above)
inval1(1).val1 := 'testx1';There is no element one (1) of 'inval1' since you haven't created any elements yet. You need to EXTEND the collection to add an element
inval1.extend();And then there is an empty element but 'inval1' is a container for objects of type 'test_object1' not for scalars like 'val1', 'val2', and 'val3'.
So you can't do
inval1(1).val1 := 'testx1';You have to create an instance of 'test_object1'
inval1(1) := test_object1('testx1', 'testx2', 'testx3');And so on for the other collection
You don't need the procedure (as my sample code shows) but once you populate the variables properly it will work.

JSP: DispalyTag - Nested table and rows

Hi!
I�d like to know if it�s possibile create new row with dispalytag.
I have a nested table (and long list), but I�d like to have the items under the header, not items in a column of the header. I tried with <tr> but doesn�t work.
Is it possibile to creat a row? And how??? I thought I must use decorators (org.displaytag.model.Row) but when I run my application it doesn't work.
Can you help me?
Thanks
Annalisa

Thanks for the quick response. I was thinking I might get a response from someone who had tried it, so I didn't waste time trying it myself. I consider your response is pretty authoritative, and I'll take that as a sign that I should forget the nested tables design.
No, polymorphic views probably won't do the job. I think I'll just go ahead and create staging versions of each detail table with foreign keys back to the master staging table. Then I'll let the wizard create the needed association objects and view links in ADF BC. It will complicate the procedure for applying changes, particularly adding a row to the change history table. But that's the price we'll need to pay.
OTOH - I just had a thought - since the change history table is mostly for auditing, it appears in some reports, but has no CRUD in the application, other than the insert when the changes are applied. If I did that insert with a trigger or some other PL/SQL, then the change history could still be a single table with nested table columns for the details.

Performance impact using nested tables and object

Hi,
Iam using oracle 11g.
While creating a package, iam using lot of nested tables created based on objects which will be passed between multiple functions in the package..
Will it have any performance impact since all the data is stored in the memory.
How can i measure the performance impact when the data grows ?
Regards,
Oracle User

This is not client code that can lay sole claim to most of the memory. It is server code and one of many server processes that need to share the available resources. So capitalism is fine on a client, but you need socialism on the server? {noformat} ;-) {noformat}
Will it have any performance impact since all the data is stored in the memory.Interestingly yes. Usually crunching data in memory is better. In this case it may not be so. The memory used is the most expensive memory Oracle can use - the PGA. Private process memory. This means each process copy running that code, will need lots of memory.
If you're not passing the data structures by reference, it means even bigger demands on memory as the data structure needs to be copied into the call stack and duplicated.
The worse case scenario is that such code consumes so much free server memory, and make such huge demands on having that in pysical memory, it trashes memory management as the swap daemons are unable to keep up with the demand of swapping virtual memory pages into and out of memory. Most CPU time is spend by the swap daemons.
I have seen servers crash due to this. I have seen a single PL/SQL process causing this.
How can i measure the performance impact when the data grows ?Well, you need to look at the impact of your code on PGA memory. It is not SQL performance or I/O performance that is a factor - just how much private process memory your code needs in order to execute.

Object view with nested table and member functions????????????????

HI frds:)
I need some help regarding writeing soem queries..
I have to use view in retreving data and by useing member functions of object.
1) i have to create a nested table by useing type object.
2) i have to create a object wtih member functions inorder to create view of taht nested table,.
3) by useing this objectt view and by useing methods i have to write soem queries ...
If any one know or any information regarding this please reply me... as i have searched in net alot but i was unable to figure out..
Thanks....

// first createing object
create type emp_det as object
(empname varcahr2(20),start_date date,end_date date);
// creating table of that object
create table emp_detai_table as table of emp_det;
// creating nested table
create table empl (emp_no number,emp_detail emp_detail_table,dep_no number)nested table emp_detail store as s;
//now i want to create view.. inorder to create view i need to create object. in that object i want to create methods.. these methods should work with date attributes..
after creating object view i need to select or write some queries by useing member methods..
This is the tast i have to perform.,. i have no materials ...if u have any link ..forward me..
i have to do it as soon as possible..

Nested tables and multiset operators in Oracle 10g

Consider the following scenario:
We have two identical relations R and S defined as:
CREATE TABLE R(
a INTEGER,
b table_type)
NESTED TABLE b STORE as b_1;
CREATE TABLE S(
a INTEGER,
b table_type)
NESTED TABLE b STORE as b_2;
where table_typ is defined as
CREATE TYPE table_typ AS TABLE OF VARCHAR2(8);
Suppose we have two instances of R and S, each having one tuple as follows: R(1,table_typ('a','b')) and S(1,table_typ('b','c')).
I would like to "merge" these two simple instances (e.g., achieve the effect of a simple SELECT * FROM R UNION SELECT * FROM S query) and obtain the following resulting instance: Result(1,table_typ('a','b','c')).
Would this be possible in Oracle 10g? A simple UNION does not work (I got a "inconsistent datatypes: expected - got SCOTT.TABLE_TYP" error). I also took a look at the MULTISET UNION operator over nested tables available in Oracle 10g, but it doesn't seem to get me anywhere. Any help on this would be greatly appreciated.
Thank you,
Laura

Unable to descripe the table and unable to drop the table

Hi,
I have a temp table that we use like staging table to import the data in to the main table through some scheduled procedures.And that will dropped every day and will be created through the script.
Some how while I am trying to drop the table manually got hanged, There after I could not find that table in dba_objects, dba_tables or any where.
But Now I am unable to create that table manually(Keep on running the create command with out giving any error), Even I am not getting any error (keep on running )if I give drop/desc of table.
Can you please any one help on this ? Is it some where got stored the table in DB or do we any option to repair the table ?
SQL> select OWNER,OBJECT_NAME,OBJECT_TYPE,STATUS from dba_objects where OBJECT_NAME like 'TEMP%';
no rows selected
SQL> desc temp
Thank in advance.

Hi,
if this table drops then it moved DBA_RECYCLEBIN table. and also original name of its changed automatically by oracle.
For example :
SQL> create table tst (col varchar2(10), row_chng_dt date);
Table created.
SQL> insert into tst values ('Version1', sysdate);
1 row created.
SQL> select * from tst ;
COL        ROW_CHNG
Version1   16:10:03
If the RECYCLEBIN initialization parameter is set to ON (the default in 10g), then dropping this table will place it in the recyclebin:
SQL> drop table tst;
Table dropped.
SQL> select object_name, original_name, type, can_undrop as "UND", can_purge as "PUR", droptime
2 from recyclebin
SQL> /
OBJECT_NAME                    ORIGINAL_NAME TYPE UND PUR DROPTIME
BIN$HGnc55/7rRPgQPeM/qQoRw==$0 TST           TABLE YES YES 2013-10-08:16:10:12
All that happened to the table when we dropped it was that it got renamed. The table data is still there and can be queried just like a normal table:
SQL> alter session set nls_date_format='HH24:MI:SS' ;
Session altered.
SQL> select * from "BIN$HGnc55/7rRPgQPeM/qQoRw==$0" ;
COL        ROW_CHNG
Version1   16:10:03
Since the table data is still there, it's very easy to "undrop" the table. This operation is known as a "flashback drop". The command is FLASHBACK TABLE... TO BEFORE DROP, and it simply renames the BIN$... table to its original name:
SQL> flashback table tst to before drop;
Flashback complete.
SQL> select * from tst ;
COL        ROW_CHNG
Version1   16:10:03
SQL> select * from recyclebin ;
no rows selected
It's important to know that after you've dropped a table, it has only been renamed; the table segments are still sitting there in your tablespace, unchanged, taking up space. This space still counts against your user tablespace quotas, as well as filling up the tablespace. It will not be reclaimed until you get the table out of the recyclebin. You can remove an object from the recyclebin by restoring it, or by purging it from the recyclebin.
SQL> select object_name, original_name, type, can_undrop as "UND", can_purge as "PUR", droptime
2 from recyclebin
SQL> /
OBJECT_NAME                    ORIGINAL_NAME TYPE                      UND PUR DROPTIME
BIN$HGnc55/7rRPgQPeM/qQoRw==$0 TST           TABLE                     YES YES 2006-09-01:16:10:12
SQL> purge table "BIN$HGnc55/7rRPgQPeM/qQoRw==$0" ;
Table purged.
SQL> select * from recyclebin ;
no rows selected

Confusion over nested tables and system generated nested tables

Hi,
I have been reading other threads about nested tables, naming and updating them etc, but I have what seems
to me some odd behaviour.
I modified my schema to set the attribute xdb:maintainDom to be false for a collection and then registered
the schema with the generate tables option defaulted to true. The result was that I had to add xdb:tableProps
attributes specifying nested table storage at each element above the collection element, this was because Oracle
was creating tables at each level. So I have this kind of thing:

XMLDATA.PTEE_SEC.PTEE STORE AS NESTED_PTEE_SEC2">When I did this the nested tables were created, but when I loaded data never had anything in them. Instead
I found that nestes tables with systems generated names like "SYSNTxxxxxxxxx" has been created that contained
the data.
When I registered the schema without the tables being generated, I created a table with this syntax:
create table poc_wip2 of xmltype
xmlschema "http://www.derwent.co.uk/wpi.xsd" element "WPI"
NESTED TABLE XMLDATA."BibPt".PTEES.PTEE_SEC.PTEE STORE AS NESTED_PTEE_SEC
NESTED TABLE XMLDATA."BibPt".INVS.INV STORE AS NESTED_INV_BIBPT(Thanks to a posting by Sam Monsarrat which showed me this was possible).
Now I had my named nested tables, which contained the data after it was loaded and no system named
nested tables.
So why the difference?
In the first instance why do my named nested tables stay empty and why does the data go into system
generated tables I have no control over as regards tablespace placement?
Is it possible to have a XML schema registered that only generates tables that I have named with the defaultTable
attribute, rather than all or nothing?
And last but not least, what's the best approach for this, since I want to be able to access the data via indexes
on the nested tables.
Thanks

Hi Pete
Would you please publish the schema you are using?

10g Nested Tables and APEX

Trying to use the following within Apex:
CREATE TYPE location_typ AS OBJECT (
location_id NUMBER(4),
street_address VARCHAR2(40),
postal_code VARCHAR2(12),
city VARCHAR2(30),
state_province VARCHAR2(25));
CREATE TYPE nt_location_typ AS TABLE OF location_typ;
CREATE TYPE country_typ AS OBJECT (
country_id CHAR(2),
country_name VARCHAR2(40),
locations nt_location_typ);
CREATE TYPE nt_country_typ AS TABLE OF country_typ;
CREATE TABLE region_tab (
region_id NUMBER,
region_name VARCHAR2(25),
countries nt_country_typ)
NESTED TABLE countries STORE AS nt_countries_tab (
(PRIMARY KEY (NESTED_TABLE_ID, country_id))
ORGANIZATION INDEX COMPRESS
NESTED TABLE locations STORE AS nt_locations_tab);
Can get Apex to function in the Tabular Report mode by modifying the query to use the correct syntax:
select "REGION_ID",
"REGION_NAME",
c.COUNTRY_ID,
c.COUNTRY_NAME,
l.LOCATION_ID,
l.STREET_ADDRESS, l.POSTAL_CODE,
l.CITY,
l.STATE_PROVINCE
from "#OWNER#"."REGION_TAB", TABLE(COUNTRIES) C, TABLE(LOCATIONS) L
Built a 'Maintenance' form. Put the Region base column on it. Then built a tabular form (with an updateable query) on the same page to access the first level Nest ( countries). Haven't figured out how to actually edit the values yet, but feel comfortable I will.
But - trying to provide editing to the 2nd level nested table elements creates a problem. First, only 1 updateable query can be on a page. Hmmm - so to get around this I guess I have to build a new page that the calling updateable query will access when selecting one of the tabular form elements. Not elegant by any means. Was hoping to provide a blank form on the right side that would be populated by the Location Nested Table values when a select was made on the first level nest. Oh well.
Just curious how anyone has handled this? I could pass stack between pages for sure, but was hoping page regions would be sufficient to handle this.
Any white papers on this? Anything in the DEMO area to use as a template? The default Demo doesn't provide this based on querying user objects.
Thanks,
