About nested tables in oracle 8i
hello,
actually i am working with oracle 8.1.5 's nested tables
concept...
here is a description of my tables
create type parameterranges
parameter_name varchar2(20),
min_value number(10),
max_value number(10)
create type parameter_ran as table of parameterranges
create table material_details
mat_type varchar2(20),
parameter_ranges parameter_ran
okay...
now my doubt is how do i place constraints on the nested table fields i.e on min_value etc...(especially NOT NULL
constraint)
DOUBT NO 2
=============
I have a query to find out the mat_type,partno from material_details table Based on the parameter value and its min_value ,i.e based on some name value pairs which I am achieving as below .
select m.mat_type,m.partno
from material_details m,table(m.parameter_ranges) p
where p.parameter ='THICKNESS' and p.min_value = '1'
and m.mat_type='STEEL'
intersect
select m.mat_type, m.partno
from material_details m,table(m.parameter_ranges) p
where p.parameter ='STANDARD' and p.min_value = 'SAE1010'
and m.mat_type='STEEL';
Now I want this to be in a cursor..i.e I want to use the same set of rows returned by the above in another query involving another table .
That is using the multiple mat_type and partno returned from above I want to find out
Other fields (company,plant) from another table part_details which also has a nested table in it
How do I go about this???Actually I want to use these in a PLSQL procedure where we can have row by row control of the rows returned ,that is why I want a cursor.......
could u think about this too...and if possible mail me at my yahoo id ..
thanx once again
please reply to my id
[email protected]
thanx

I don't understand exactly your problem. Can you send me a mail which expresses your problem??

Hallo everyone,
I have a problem with nested tables. I can create them and insert data with the sql command line. It is not possible in the browser.
But I cannot view the values - neither in the command line nor in the browser.
In the browser, oracle shows this error-message:
'ORA-01031 insufficient privileges' (I have admin rights!!)
Is it possible that Oracle Express Edition doesn't support all object-oriented features?
Thanks in advanceI downloaded the latest apex 3.0.1, but itshouldn't
be used with Oracle XE according to theinstallation
guide.Where did you read that? There's even a XE releated
install guide:

Database XE and Application Express 3.0.1C.
when I downloaded apex, the documentation in the database requirement (2.1) says:
"Note:

Maybe the documentation is not up to date, because I downloaded last week -
How to create Nested table in oracle stored procedure(Temp Table)

But i can't insert value in to this temp table
Plz help meWhat is problem?

Require help on Array of Nested tables and Oracle Object type
Hi All,
I have a scenario where I have some millions of records received from a flat file and the record is stored in Table as below:
Tablename: FILE_RECORD
Rows:
FILE_REG_ID = 1
RECORD_NBR = 1
PROCESSED_IND = U
RECORD= 00120130326006A
FILE_REG_ID = 1
RECORD_NBR = 2
PROCESSED_IND = U
RECORD= 00120130326003
1) I have to read these records at once and
a) Split the RECORD column to get various other data Eg: Fld1=001, Fld2=20130326, Fld3 = 003
b) send as an Array to Java.
2) Java will format this into XML and sent to other application.
3) The other application returns a response as Successful or Failure to Java in XML
4) Java will send RECORD_NBR and the corresponding response as Success or Failure back to PLSQL
5) PLSQL should match the RECORD_NBR and update the PROCESSED_IND = P.
I 'm able to achieve this using SQL Table type by creating a TYPE for Each of the fields (Flds) however the problem is Java cannot Access the parameters as the TYPE are of COLUMN Types
Eg: For RECORD_NBR
SUBTYPE t_record_nbr IS FILE_RECORD.T010_RECORD_NBR%TYPE;
Can you please let me know how I can achieve this to support Java, I know one way that is by creating an OBJECT TYPE and a TABLE of the OBJECT TYPE.
Eg: T_FILE_RECORD_REC IS OBJECT
FILE_REG_ID number(8), RECORD_NBR number (10), PROCESSED_IND varchar2(1), RECORD varchar(20)
Create type T_FILE_RECORD_TAB IS TABLE OF T_FILE_RECORD_REC
However I'm facing a problem to populate an Array of records, I know I'm missing something important. Hence please help.
It would be helpful to provide some guidelines and suggestions or Pseudo or a Code to achieve this. Rest all I can take up further.
Thanks in advance,I know once way that is creating a OBJECT TYPE and a TABLE of OBJECT TYPE, howeve I feel I'm missing something to achieve this.You're right, you need SQL object types created at the database level. Java doesn't know about locally defined PL/SQL types
However you can do without all this by creating the XML directly in PL/SQL (steps 1+2) and passing the document to Java as XMLType or CLOB.
Are you processing the records one at a time? -
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:
<xsd:element name="BibPt" xdb:SQLType="BIBPT_T"
xdb:defaultTable="BIBPT"
xdb:tableProps="NESTED TABLE XMLDATA.PTEES.PTEE_SEC.PTEE STORE AS NESTED_PTEE_SEC
NESTED TABLE XMLDATA.INVS.INV STORE AS NESTED_INV_BIBPT TABLESPACE BIBLIO">
<xsd:element name="Ptees" xdb:SQLType="PTEES_T" xdb:tableProps="NESTED TABLE
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
PeteHi Pete
Would you please publish the schema you are using?
Thanks,
Tobias -
Went into an Apple store yesterday, and bought myself a copy of iWork '08, and spoke to the specialist about nested tables. He had no idea how they worked (after I said in the trial they didn't nest). Do tables actually nest in Pages, or not? If I create a table, click in a cell and create another table, it appears above or below the first table, not in it!
This is very annoying, as my CV done in Word '07 on Windows utalises Nested tables to make things line up properly. Is there a way that Pages can do this sort of thing wihtout a table?As the trial version is exactly the same as the full one, it's not surprising that they behave the same.
It's perfectly true: we aren't allowed to define a table in a cell.
_Go to "Provide Pages Feedback" in the "Pages" menu_, describe what you wish.
Then, cross your fingers, and wait _at least_ for iWork'09
This is very annoying, as my CV done in Word '07 on Windows utalises Nested tables to make things line up properly. Is there a way that Pages can do this sort of thing wihtout a table?
Exactly like other tools, using ruler's tabs.

Hi.
Where can i find information abount using temp tables in Oracle?
I usually work with SQL Server and use temp tables. I don't have any idea about temp tables in Oracle. Could you give me any information?
Thanks.
I'm sorry for may english, I'm spanish.There are two completely different things being discussed here temporary segments used by Oracle's internal processes and Oracle global temporary tables.
Or did I misunderstand?
We have used Oracle's global temporary tables as quick staging array while data is being integrated into finance apps. Testing showed the process performed faster with this design.
Both temporary segments and Oracle's global temporary tables are stored in the TEMP tablespace. -
Simple question aboout PL/SQL nested tables
Hello, my question is about nested tables. Suppose I have a nested table:
TYPE int_array IS TABLE OF INT;
v_int_array int_array;
Is there a built in function to allow me to search v_int_array for a specific integer value?
GeorgeUse MEMBER OF operator:
declare
TYPE int_array IS TABLE OF INT;
v_int_array int_array := int_array(1,2,3,4,5);
begin
if 1 member of v_int_array
then
dbms_output.put_line('Found it!');
end if;

Oracle object, nested table on a subtype
Hello,
Is it possible to have a nested table on a subtype? If it is, can someone help me?
Here is what I need help for:
I have a supertype WORK, that have:
multivalued attribute ADDRESS
a attribute NAME, also the primary key
The subtype is called EMPLOYEE, that have:
multivalued attribute SPECIALTY
a attribute NAME
a attribute SSN
So far have I got:
//* The supertype *//
create or replace type ADRESS_TP as object(
ADRESS varchar2(50));
create or replace type ADRESSTP as table of ADRESS_TP;
create or replace WORK_TP as object(
NAME varchar2(30),
ADRESS ADRESSTP)
NOT FINAL;
create table WORK_TBL of WORK_TP(
Primary key(NAME))
nested table ADRESS store as NT_ADR(
(Primary key(nested_table_id, ADRESS))
organization index compress);
//* The subtype *//
create or replace type SPECIALTY_TP as object(
ADRESS varchar2(50));
create or replace type SPECIALTYTP as table of SPECIALTY_TP;
create or replace EMPLOYEE_TP under work_tp(
NAME varchar2(30),
SSN number)
FINAL;
The multivalued attribute SPECIALTYTP has to be declared in WORK_TBL have I been told, but how can I do that?
I'm using oracle 9iI'm not really sure what your problem is. In future please be specific about what it is you are trying to do and what it is that is not working. If it's an error please give us the error message and number. It's not the behaviour you are expecting please describe what it does. If it's that you simply don't understand please say what you don't understand.
I go on like this because the code you have posted is somewhat confusing. The Oracle object-oriented implementation is not quite complete so that makes it hard for people who know OO but don't know Oracle. Whereas most of us who know Oracle aren't expert in OO. Also, I think you should be slightly more inventive in your names: there's so many things called ADRESS it's easy to get them tangled up.
Anyway, here's my guess at what I think your problem is....

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.

Problems with Whitespace using nested tables from eclipse dtp oracle plugin
Hi,
sending from eclipse to oracle xe fails if whitespace is used:
Example1: Nested table in nested table
adress_table_typ has another nested table in it
that works
CREATE TABLE x (
i INTEGER PRIMARY KEY,
adressen adress_table_typ
) NESTED TABLE adressen STORE AS adressen_nt (NESTED TABLE tels STORE AS tels_nt);
inserting a newline fails
CREATE TABLE x (
i INTEGER PRIMARY KEY,
adressen adress_table_typ
) NESTED TABLE adressen STORE AS adressen_nt
(NESTED TABLE tels STORE AS tels_nt);
Example2:
Two nested tables
CREATE TABLE x (
i INT PRIMARY KEY,
l_table_typ,
m_table_typ
) NESTED TABLE laptops STORE AS laptop_nt NESTED TABLE interessen STORE AS interessen_nt;
and then an insert
INSERT INTO x VALUES (123456,
l_typ(laptop_typ('123', 'netop'),
laptop_typ('234', 'thinkpad'),
laptop_typ('345', 'iBook')),
m_typ('a', 'b', 'c')
which fails. Note that the INSERT works when copy&pasted to sqlplus. It also works if there is
just one nested table.
Am I doing somethig wrong or is this a bug in the eclipse data tools plugin?
Regards
- Peter
PS; It is rather difficult to insert whitespace in that forum editor. Any possibility to have ascii?
For a "whitespace" question rather important...A bit of an update on the original post. I was playing around with the plug-in xml file (e.g. eclipse\plugins\org.eclipse.jst.server.generic.oc4j_1.5.100.v20070608\buildfiles\oracle.10.1.3.xml). I changed the following from "deploy" to "redeploy" and it seems to be working once the applicatoin is initial deployed. Of course, I have to change it back to "deploy" if it is the first time the application is being deployed. However; I would still would like to resolve this if there is something out there that fixes this problem. Or if everything points to an enviornment problem, I can continue to play with it.

Nested Table having more than 1 column comparison using ORACLE MULTISET
Dear ALL,
I am using ORACLE 10gR2 Database.
I am currently trying to compare two sets of data that I get from two queries in PL/SQL. I want to use Oracle MULTISET UNION, MULTISET INTERSECT, MULTISET EXCEP for those operations.
But When I am executing the below given code I am getting the error.

IS THERE ANY WAY ORACLE IS PROVIDING A FUNCTIONALITY WHERE WE CAN HAVE A NESTED TABLE WITH MULTIPLE COLUMNS AND THAT CAN BE USED IN PL/SQL AND USE BULK OPERATION TO POPULATE THE NESTED TABLE WITH MULTIPLE COLUMNS AND USE THE SAME IN MULTISET EXCEPT, MULTISET EXCEPT ETC.
Appreciate your help on this.
Thanks,
Madhu K.Madhu,
I am totally amazed. I didn't think any of the MULTISET operations would work with NTs of records. Lucky you!
As for the EXCEPT, well, clearly it is a restriction or bug in PL/SQL.
You may want to report it to Oracle Support.

FYI: If I comment the MULTISET EXCEPT conditin then I am getting the output for MULTISET UNION.
IS THERE ANY WAY ORACLE IS PROVIDING A FUNCTIONALITY WHERE WE CAN HAVE A NESTED TABLE WITH MULTIPLE COLUMNS AND THAT CAN BE USED IN PL/SQL AND USE BULK OPERATION TO POPULATE THE NESTED TABLE WITH MULTIPLE COLUMNS AND USE THE SAME IN MULTISET EXCEPT, MULTISET EXCEPT ETC.
Appreciate your help on this.
