ORA-00902 on trying to Select a Nested Table

I have created a Table having Nested Table as below:
create type INT_ARRAY as table of INTEGER;
create table test1 (
id number not null,
name varchar2(500),
prot_NT int_array,
constraint test1_pk primary key(id))
STORAGE (INITIAL 512K
NEXT 512K
MINEXTENTS 1
MAXEXTENTS UNLIMITED
PCTINCREASE 0)
nested table prot_NT store as prot_NT_TAB ;
And I am doing following select using an executeQuery on a PreparedStatement (I am not using any oracle extensions. I am using JDK1.2.2 on Solaris with Weblogic 5.1 appServer. jdbc driver is oracle.jdbc.driver.OracleDriver version 8.1.6.0.0):
Select id, name, prot_nt from test1
Some times this executeQuery works fine. But some times I get SQLException with "ORA-00902: invalid datatype". Same tables and same query behaves differently at different times.
Is there any problem with this usage?? Is there any known problem? I am trying to get Nested Table to a int[]. What is recommended procedure for doing this? Please help me out! Thanks in advance!

By this point you've probably either solved the problem, or just dropped the database, but for anyone else interested, here's something you can do.
You can drop the queue table by setting event 10851 with the following steps:
1. Log into SQL*Plus or Server Manager as a user with DBA privileges.
2. Issue command: alter session set events '10851 trace name context forever, level 2'; Statement Processed.
3. Drop table <queue_table>; Statement Processed.
Solution Explanation: =====================
Event 10851 disables error 24005 when attempting to manually drop a queue table. It should be noted that this is the "Hard Way" of dropping queue tables, and should only be practiced after all formal procedures, i.e., using the "DBMS_AQADM.DROP_QUEUE_TABLE" procedure, has failed to drop the table.

Correct, object references (REFs) can only refer to row objects, not nested column objects.Well, I'm not trying to reference a column object.
Technically speaking, the target table (CHART$ENTRY_POINT_SET) is an object table (albeit a nested table), isn't it?

[solved] trying to select on a table type

Hello I am trying to shift data from one schema to another, but while I am shifting it I also want to perform a consolidation on it.
My SQL looks like
declare
cursor basedata_cur is
select cost_centre_id, mm.new_expid expense_type_id, period_id, year_,
data_type_id, measure_id,sum(value) value from basedata_normprd BDN

type basedata_rec_type is table of basedata_cur%ROWTYPE index by PLS_INTEGER;
basedata_rec basedata_rec_type;
loop_cntr INTEGER;

end;
Can I replace the for loop. looping over the table collection and instead replace with a select to dump the data all in one single shot.
I'm doing it this way because the database is a bit short of space and I don't want to bust the redo/undo and archiver space on the database.
I tried
Select cost_centre_id, expense_type_id, period_id, year_,
data_type_id, measure_id, value from table(basedata_rec);
but I get an error about accessing rows from a nested table.
Can anyone suggest a solution. or maybe a better way to do this.

Select from nested table

Hi,
I create following types and table:
CREATE OR REPLACE TYPE obj_query AS OBJECT
(emp_id NUMBER(6)
,emp_first VARCHAR2(20)
,emp_last VARCHAR2(25));
CREATE OR REPLACE TYPE tab_query AS TABLE OF obj_query;
CREATE TABLE queryEmp
(id_row NUMBER
,beginTrans VARCHAR2(15)
,queryA VARCHAR2(100)
,resultEmp tab_query)
NESTED TABLE resultEmp
STORE AS nested_queryEmp;
I would like the output of the table queryEmp like this:
id_row beginTrans queryA emp_id emp_first emp_last
1 15:00 Select1 100 Joe King
101 John Queen
2 15:10 Select2 100 Leo King
101 Mett Queen
But Can I get this result with only SQL SELECT statement from this table?
I don't want to use PL/SQL, only SELECT in SQL*Plus.
Thank you
I'm sorry but output looks so bad.
So, I want to get the one row of id_row, beginTrans, queryA and all rows of nested table dmlStats to this "main" row and so on.
But not in PL/SQL
I hope, you understand me.
Thanks

HOw to improve insert/update/select for nested table.

Hi All,
I think this is my second thread for nested table.
i just want to know what are the different ways available to improve the insert/update/select operation on Nested table.
Thanks in advance.

By not using a nested table for data storage in the first place...
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:8135488196597
Perhaps Parallel Query/DML might give some relief.

Value select from nested table

CREATE TYPE test AS OBJECT (
test1 varchar2(10),
test2 varchar2(10));
create or replace type test2 as table of test;
two record are there within object type.then how i will select value from nested table.

How many times are you going to ask this question before you either look at the response I have given to Re: how i will display type like (nestedtable or varrays or pl/sql table).?
You have posted often enough to this forum to know the ettiquette by now.

SQL Select into Nested Table

Hi,
I would like to be able to store results of a query in the database. So far, I believe the best method is to store it as a nested table so that I may refer to it by criteria (e.g. date, name, etc.). I am somewhat new to Oracle and I'm not sure how to do this.
The query will always return the same columns, so that should make it easier for me. Also, I need to be able to query the data that is stored into an APEX report region.
Can someone tell me if this is the best method to do this? Also, is there a tutorial anywhere that explains how to do what I want?
Thanks in advance,
-David

I'm not sure how to do this.Given that you're new to Oracle how did you decide the best approach was a nested table? As most people who know anything at all about Oracle would take the opposite view (as Dan has done).
Let's drill down into your requirements some more. How long do what to retain the results for? Do you want to retain the results of many queries? If so, will these queries be the same shape (same number and type of columns) or will they be different? Do you want one user to be able to see the results of another user's queries? Do you want to associate metadata with these result sets?
In fact, why do you want to be able to store these result sets at all? Oracle is actually pretty good at caching data, especially in 11g. So you may be re-inventing a wheel and designing it wonky at that.

Error while create trigger on for nested table

I want to insert a record into a nested table.For this, I created a view for the table, which includes the nested table.It told me ORA-25015 cannot perform DML on this nested table view column.So I created a trigger for the nested table.However, it told me that ORA-25010 Invalid nested table column name in nested table clause.I think my nested table is valid, i don't konw why did it appear this kind of problem?

Hi,TongucY
Compared with the "Referencing Clause with Nested Tables" part of this reference -
http://psoug.org/reference/instead_of_trigger.html, I found the answer of this
quesion. That is "CREATE OR REPLACE TYPE " VARRAY_DEPT_SEQ" as[b] varray(930) of
DEPT". It turns to be a varying array, not a nested table. It should be "CREATE OR
REPLACE TYPE " VARRAY_DEPT_SEQ" as table of DEPT". That is OK. Thank you very
much!
While there is an another question, if I create a varying array like" CREATE OR
REPLACE TYPE " VARRAY_DEPT_SEQ" as[b] varray(930) of DEPT " and I want to insert
a record into the varying array, which the record has been existed.The method that
create a view and a trigger seems not to be effective.
For instance,
There is a record in the table
ID:1020
CREATE_DATE:2005-10-20
UPDATE_DATE:2007-2-11
DETPS: ((10225,AMY))
I want to ask this record to be
ID:1020
CREATE_DATE:2005-10-20
UPDATE_DATE:2007-2-11
DETPS: ((10225,AMY),(10558,TOM))
How should I do?
Could you please help me?
Best regards.

Elements order in Nested Tables

In PL/SQL when I am adding element to a nested table of objects one by one(in order), and then trying to insert that nested table type to a physical table , the order of element changes. how can I prevent this behavior?

Your example is incomplete and has errors. Oracle does not guarantee the order of anything unless you use an order by clause. So, if you expect the following to produce rows in some order:
Open cur1 for select * from another_table;
then you need to add an order by clause, such as:
Open cur1 for select * from another_table order by id;
The following does minimal correction, completion, and provides sample data to demonstrate:

Thank's

I've created a simple example :
1.Create types and table.
2.Fill table with sample data
3.Run queryCtx := DBMS_XMLQuery.newContext('select * from TestTable'); to generate XML
4.delete testtable
5.Run rows := DBMS_XMLSave.insertXML(insCtx,xmlDoc); with the generated xml.
6.The table testtable will have 2 rows with the same 1 row collection xlist !!!
CREATE OR REPLACE TYPE Test_Type
AS OBJECT (
x number
create or replace type Test_List_Type as table of Test_Type
create table TestTable (
XX number,
XLIst Test_List_Type
nested table XLIst store as TestTable_XLIst_NEST
insert into
testtable
(xx,xlist)
values
(1,Test_List_Type (test_type(10)))
insert into
testtable
(xx,xlist)
values
(1,Test_List_Type (test_type(10)))
insert into
testtable
(xx,xlist)
values
(2,Test_List_Type (test_type(20),test_type(21),test_type(22),test_type(23)))
script to insert xml
declare
insCtx DBMS_XMLSave.ctxType;
rows number;
xmldoc clob;
-- xxslt clob;
begin
select cclob into xmldoc from cc.ka_clob; -- (I've stored xml in this table)
insCtx := DBMS_XMLSave.newContext('testtable'); -- get the context handle
DBMS_XMLSave.Setignorecase(insctx,1);
rows := DBMS_XMLSave.insertXML(insCtx,xmlDoc); -- this inserts the document
DBMS_XMLSave.closeContext(insCtx); -- this closes the handle
commit;
end;

Export using TOAD for a nested table?

I am trying to export a nested table via TOAD, however, the fields which are part of nested data (dataset) does not export.
Any suggestions on an alternative solution?
Thanks.
