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.
<target name="deploy.j2ee.ear" depends="check.skip.ear.deploy" unless="skip.deploy">
<antcall target="package.module.ear"/>
<oracle:redeploy
deployerUri="${deployer.uri}"
userId="${oc4j.admin.user}"
password="${oc4j.admin.password}"
file="${server.publish.dir}/${module.name}.ear"
deploymentName="${module.name}"
bindAllWebApps="${oc4j.bind.website}"/>

Problem in creating a nested table

Hi i am working on Oracle 10g and cleint is sqlplus.
Now while creating a nested table following error occured.
This is the script for your reference.:
CREATE OR REPLACE TYPE sec_pwd_hist_table
AS
TABLE OF sec_pwd_history_type
index by binary_integer
Warning: Type created with compilation errors.
SQL> show error
Errors for TYPE SEC_PWD_HIST_TABLE:
LINE/COL ERROR
0/0 PL/SQL: Compilation unit analysis terminated
3/1 PLS-00355: use of pl/sql table not allowed in this context
Please help on this issue
Regards,
Vikas Kumar

> but i want to know just one thing why its working when i am removing "INDEX BY binaty_integer"
Vikas, I trust I answered that question when I said? :
"Do not confuse the two. Do not attempt to use PL/SQL array struct definition syntax in the SQL engine for defining an ADT collection. Which is why I referred you to the manual to see how an ADT is defined in SQL."
In other words, you are trying to apply a PL/SQL concept and PL/SQL syntax to a definition of a data type in SQL.
SQL is not PL/SQL.
SQL ADTs are not PL/SQL arrays/tables.
It is not even a syntax issue - it is a basic concept issue. SQL does not support PL/SQL arrays/tables. Period.

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?
My table is
CREATE TABLE ENT
ID NUMBER(7) NOT NULL,
CREATE_DATE VARCHAR2(11 BYTE),
UPDATE_DATE VARCHAR2(11 BYTE),
DEPTS VARRAY_DEPT_SEQ
CREATE OR REPLACE
TYPE DEPT AS OBJECT
ID NUMBER(8),
ANCHOR VARCHAR2(20),
CREATE OR REPLACE
TYPE " VARRAY_DEPT_SEQ" as varray(930) of DEPT
CREATE OR REPLACE VIEW ENT_NESTED_VIEW
(ID, CREATE_DATE, UPDATE_DATE, DEPTS)
AS
select e.ID,cast(multiset(select r.id,r.anchor from ent z, table(z.depts) r where z.ID=e.ID )as varray_dept_seq)
FROM ENT e
Then when I created trigger;
CREATE OR REPLACE TRIGGER EMP.ENT_NESTED_TRI
INSTEAD OF INSERT
ON NESTED TABLE DEPTS OF EMP.ENT_NESTED_VIEW
REFERENCING NEW AS New OLD AS Old PARENT AS Parent
FOR EACH ROW
BEGIN
END ;
I met the problem: ORA-25010 Invalid nested table column name in nested table clause
Could you please tell me the reason
Thank you!
My insert SQL is:
insert into table(select depts from ent_nested_view where id=1856) values(varray_dept_seq(dept(255687,'AF58743')))

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.

Reg: Querying Nested table.

Hi,
I am facing a problem with querying the Nested table.
I have created a type
CREATE OR REPLACE TYPE TY_BOOKS OBJECT(           VC_BOOK_NAME VARCHAR2(64)          );
CREATE OR REPLACE TYPE NT_TY_BOOKS AS TABLE OF TY_BOOKS;
I have used this nested table in a table Student.
CREATE TABLE STUDENT
( SID NUMBER(10),
CL_NT_BOOKS NT_TY_BOOKS)
NESTED TABLE CL_NT_BOOKS STORE AS CL_NT_BOOKS_TAB;
The problem is one student can have more than one book. So if I need to select the students who have 'Science' books, i wrote this query.
SELECT S.SID,B.VC_BOOK_NAME FROM STUDENT S, TABLE(CL_NT_BOOKS) B WHERE B.VC_BOOK_NAME='Science';
suppose in the table
SID BOOK_NAME
1000          CL_NT_BOOKS('Science')
1001          CL_NT_BOOKS('Maths'),CL_NT_BOOKS('Science')
This query will return only those student-ids who have only "Science" book not those student-ids who have "Maths" & "Science" books.
RESULT
1000          Science
but not 1001....
Please can any one send me the select query which can select iteratively for books names which contains more than one value.

Hmm, mysterious. It works for me on my 9.2.0.6 dB...
SQL> CREATE OR REPLACE TYPE TY_BOOKS AS OBJECT( VC_BOOK_NAME VARCHAR2(64) );

SQL> CREATE OR REPLACE TYPE NT_TY_BOOKS AS TABLE OF TY_BOOKS;

      1001 Science
SQL> What I suggest is most likely to have happened is that you have added a space or some other non-printing cahracter into the book name when you inserted row 1001. If this is not the case then you'll have to do it again in SQL*Plus, cut teh output and paste it here, so we can see what's going on.

Trigger with Nested Table

How do I reference a column in a nested table in a trigger. I am issuing an update statement:
UPDATE TABLE (SELECT inv_level
FROM inventory_level
WHERE machine_id = '1111'
SET inventory_level = '15'
WHERE column_id = '2'
I want to create a trigger that execute before the insert. I want to insert the machine_id, the column_id, inventory_level into a change history table. The issue is he column_id and inventory_level fields are in the nested table. I tried to reference them as :NEW.column_id, but that didn't work.

I too have had problems working with triggers & nested tables. This may help
Imagine the scenario of a table that holds customer data that needs a specific record per user of the database to indicate if they can contact that customer.
To solve this I created the following
create type contact_type as object
(username varchar2(30),
can_mail number,
can_phone number);
create type contact_nt_type as table
of contact_type;
--table cust
create table cust_table(
custid number,
custname varchar2(50),
contact_nt contact_nt_type)
nested table contact_nt store as contact_nt_tab;
-- populate tables
insert into cust_table
values(1001,'Customer1',
contact_nt_type(
contact_type('SCOTT',1,0),
contact_type('TIMS',0,1)));
insert into cust_table
values(1002,'Customer2',
contact_nt_type(
contact_type('SCOTT',0,0),
contact_type('TIMS',0,0)));
-- view cust_vu
create or replace view cust_vu
as
select ct.custid, ct.custname, nt.can_mail, nt.can_phone
from cust_table ct, table(ct.contact_nt) nt
where nt.username = user;
Now, if scott looks at the customer through the view he sees one set of contact details and if I look I see another. But if we try to update the view we get
ORA-01733: virtual column not allowed here
To solve this create an "instead of" trigger
create or replace trigger cust_vu_update
instead of update on cust_vu
for each row
begin
-- update the parent table
update cust_table
set custname = :new.custname
where custid = :old.custid;
-- update the nested table
update table(
select contact_nt
from cust_table
where custid = :old.custid)
set can_mail = :new.can_mail,
can_phone = :new.can_phone
where username = user;
end;
The documentation has a whole section on triggers & nested tables which, for me, did not solve any of my issues. Following the Create trigger syntax, specifically the dml_event_clause, caused me 0600 errors and my session was terminated!
There may be better solutions but this one works for me.

Problem when expanding Tree - Tree with nested table column

Hi, i have created the tree using the Tree with nested table column.
I have created a node called TREE_ROOT in the context.
This node has few attributes which includes children_loaded, is_leaf, is_expanded.
I have created the recursive node TREE_SUB for the above node TREE_ROOT.
In the view, i have created the table with the master column. The above attributes have been mapped accordingly. I have created the action handler for load_children.
In this action handler method, i receive the context_element correctly. In this method, i determine the children of the selected element and the resulting children are attached to this context_element.
But the problem is: when i add elements to context_elements in the method load_children, these
elements get added to the node TREE_ROOT as well.
Please help.
thanks and best regards,
Pramod

Problem with Nested Table

I am trying to make a nested table receive an arbitrary number of values (from a shuttle) through a loop, and then insert the table into a table of nested table in my database. The problem I am having is that when I try to insert more than one value into the nested table, it will only insert the last item in the loop into the database. Thanks in advance.
This is the code I used to create my objects:
create or replace type OUTPUT_TY as object( ATTRIBUTE_ID Number(8) )
create or replace type OUTPUTS_NT as table of OUTPUT_TY
This is my actual code in ApEx:
declare
temp_NT OUTPUTS_NT;
temp_TY OUTPUT_TY;
temp Number(10);
l_vc_arr2 htmldb_application_global.vc_arr2;
begin
temp_nt := outputs_nt();
l_vc_arr2 := HTMLDB_UTIL.string_to_table (:P2_SHUTTLE, ':');
FOR i IN 1 .. l_vc_arr2.COUNT
LOOP
temp_ty := output_ty(l_vc_arr2(i)) ;
temp_NT:= outputs_nt(temp_ty);
END LOOP;
INSERT INTO OUTPUT_TEST values (temp_NT);
commit;
end;

> temp_NT:= outputs_nt (temp_ty);You are not extending the nested table / collection, you are simply assigning an entirely new collection to it for each element of l_vc_arr2.
Try something like...
FOR i IN 1 .. l_vc_arr2.COUNT LOOP
   temp_ty := output_ty (l_vc_arr2 (i));
   temp_nt.EXTEND;
   temp_nt (temp_nt.LAST) := temp_ty;
END LOOP;Or perhaps more succintly...
FOR i IN 1 .. l_vc_arr2.COUNT LOOP
   temp_nt.EXTEND;
   temp_nt (temp_nt.LAST) := output_ty (l_vc_arr2 (i));
END LOOP;

Public Synonyms for Nested Tables - Insertion Problem

Hi,
we are facing a problem during implementation. Our DB set up

In the schema, OWNR we have to create all the tables,

Hi
I am not sure but maybe you need to use this command:

SITA_ADDRESSES_TY() instead SITA_ADDRESSES_NT

Thank you for your reply.
I have tried
select value(t) from table t;
but it is still not working. I got almost the same answer as before.
Anyway thank you very much again.

Try this:
select value(t) from table t;

Nested Table Problem

Hello,
I am using Oracle10g and TopLink 10.1. I would like to implement a table descriptor which has nested tables.
When I try to read "root" table, I get error messages described below.
Could anybody tell me what's wrong?
Thanks,

Thank you for your reply. Maybe my explanation was confusing.
>Parent should map to the PARENT table,
Child should map the CHILD
and ChildMaster should map to the CHILD_MASTER table.
Exactly. What I want to do is "Parent has Child" using OneToMay, "Child has ChildMaster" using Multitable. I guess it's still unclear...
Anyway, I appreciate your advice.

Problem in truncate/drop partitions in a table having nested table columns.

Hi,
I have a table that has 2 columns of type nested table. Now in the purge process, when I try to truncate or drop a partition from this table, I get error that I can't do this (because table has nested tables). Can anybody help me telling how I will be able to truncate/drop partition from this table? IF I change column types from nested table to varray type, will it help?
Also, is there any short method of moving existing data from a nested table column to a varray column (having same fields as nested table)?
Thanks in advance.

Unfortunately you can't do those operations when a table has a nested table column. No truncate, no drop, no exchange partition at the partition level.
A nested table column is stored as a separate table and acts like a 'child' table with foreign keys to the 'parent' table. It is these 'foreign keys' that prevent the truncation (just like normal foreign keys prevent truncating partions and must be disabled first) but there is no mechanism to 'disable' them.
Just one excellent example (there are many others) of why you should NOT use object columns at all.
>

Yes but I STRONGLY suggest you take this opportunity to change your data model to a standard relational one and put the 'child' (nested table) data into its own table with a foreign key to the parent. You can create a view on the two tables that can make data appear as if you have a nested table type if you want.
Assuming that you are going to ignore the above advice just create a new VARRAY type and a table with that type as a column. Remember VARRAYs are defined with a maximum size. So the number of nested table records needs to be within the capacity of the VARRAY type for the data to fit.

Sure - just CAST the nested table to the VARRAY type. Here is code for a VARRAY type and a new table that shows how to do it.
-- new array type
CREATE OR REPLACE TYPE ARRAY_T AS VARRAY(10) OF VARCHAR2(64)
-- new table using new array type - NOTE there is no nested table storage clause - arrays stored inline
CREATE TABLE partitioned_table_array
     ( ID_ INT,
      arra_col ARRAY_T )
     PARTITION BY RANGE (ID_)
     ( PARTITION p1 VALUES LESS THAN (40)
     , PARTITION p2 VALUES LESS THAN(80)
     , PARTITION p3 VALUES LESS THAN(100)
-- insert the data from the original table converting the nested table data to the varray type
INSERT INTO PARTITIONED_TABLE_ARRAY
SELECT ID_, CAST(NESTED_COL AS ARRAY_T) FROM PARTITIONED_TABLENaturally since there is no more nested table storage you can truncate or drop partitions in the above table
alter table partitioned_table_array truncate partition p1
alter table partitioned_table_array drop partition p1

Create a view problem on nested tables

I have a table which has a column of nested table:
create table Person (
id NUMBER(10), --primary key
attr1 varchar2(10),
attr2 varchar2(10),
kids KIDS_NT --KIDS_NT is a nested table of object
--which has two columns: name, age.
) nested table store as kids_nt_tab;
Now I like to create a view which has the id (key), concatenation of attr1 and attr2 with a ".", and count of how many kids this persion has):
create view Person_V as (
select id, attr1||'.'||attr2 as attr12,
count(*) from A a, table(a.kids)
group by id)
This won't work since it says attr1.attr2 is not a GROUP BY expression. If I don't specify a group by statement, it will say "not a single group group function).
One solution that I think it will work but quite ugly is to create a view of id and attr1.attr2, andother for id and kids count, then a final view to join them.
Does anyone have a better solution? Thanks in advance!
Alice

One way could be:
SQL> create or replace type kids as object (
2         name varchar2(10),
3         age number) ;
4 /
Type created.
SQL>
SQL> create or replace type kids_nt as table of kids ;
2 /
Type created.
SQL>
SQL> create table Person (
2      id NUMBER(10) primary key,
3      attr1 varchar2(10),
4      attr2 varchar2(10),
5      kids KIDS_NT
6 ) nested table kids store as kids_nt_tab;
Table created.
SQL>
SQL> insert into Person values (1, 'attr1', 'attr2', kids_nt(kids('kid1', 10), kids('kid2', 8))) ;
1 row created.
SQL> insert into Person values (2, 'attr1', 'attr2', kids_nt(kids('kid1', 6), kids('kid2', 13))) ;
1 row created.
SQL>
SQL> select id, attr1||' '||attr2, (select count(*) cnt from table(p.kids)) cnt
2 from Person p
3 /
        ID ATTR1||''||ATTR2             CNT
         1 attr1 attr2                    2
         2 attr1 attr2                    2
2 rows selected.
