MetaData for nested table type

in a nested table a column is of datatype "TYPE"
so how can i get metadata for this column..
if "OPTIONS" is a column of datatype "TYPE"
and it has 2 columns option_id and option_value
then when i'am trying to get
array.getBaseTypeName
m gettin TAB_TY_OPTION_DETAILS
like this only..
how can i get metadata for this datatype.
Thanks in advance.

Trigger how to get new and old value for nested table column?

Hi,
I have created a nested table based on the following details:
CREATE TYPE typ_item AS OBJECT --create object
(prodid NUMBER(5),
price NUMBER(7,2) )
CREATE TYPE typ_item_nst -- define nested table type
AS TABLE OF typ_item
CREATE TABLE pOrder ( -- create database table
ordid NUMBER(5),
supplier NUMBER(5),
requester NUMBER(4),
ordered DATE,
items typ_item_nst)
NESTED TABLE items STORE AS item_stor_tab
INSERT INTO pOrder
VALUES (800, 80, 8000, sysdate,
typ_item_nst (typ_item (88, 888)));
Now I would like to create a trigger on table pOrder for after insert or update or delete
and I would like to track the new and old value for the columns inside nested table.
Can anybody direct me how to do it?
I would like to know the sytax for it like:
declare
x number;
begin
x := :new.nestedtablecolumn;--how to get the new and old value from nested table columns
end;
Hope my question is clear.
Thanks,
Lavan

Hi,
Try like this:
CREATE OR REPLACE TRIGGER PORDER_I
BEFORE INSERT
ON PORDER
REFERENCING OLD AS old NEW AS new
FOR EACH ROW
DECLARE
items_new typ_item_nst;
ordid_NEW NUMBER;
BEGIN
FOR i IN :new.items.FIRST .. :new.items.LAST LOOP -- For first to last element
DBMS_OUTPUT.PUT_LINE(':new.items(' || I || ').prodid: ' || :new.items(I).prodid );
DBMS_OUTPUT.PUT_LINE(':new.items(' || I || ').price: ' || :new.items(I).price );
END LOOP;
END;Regards,

Java call stored procedure with nested table type parameter?

Hi experts!
I need to call stored procedure that contains nested table type parameter, but I don't know how to handle it.
The following is my pl/sql code:
create or replace package test_package as
type row_abc is record(
col1 varchar2(16),
col2 varchar2(16),
col3 varchar2(16 )
type matrix_abc is table of row_abc index by binary_integer;
PROCEDURE test_matrix(p_arg1 IN VARCHAR2,
p_arg2 IN VARCHAR2,
p_arg3 IN VARCHAR2,
p_out OUT matrix_abc
END test_package;
create or replace package body test_package as
PROCEDURE test_matrix(p_arg1 IN VARCHAR2,
p_arg2 IN VARCHAR2,
p_arg3 IN VARCHAR2,
p_out OUT matrix_abc
IS
v_sn NUMBER(8):=0 ;
BEGIN
LOOP
EXIT WHEN v_sn>5 ;
v_sn := v_sn + 1;
p_out(v_sn).col1 := 'col1_'||to_char(v_sn)|| p_arg1 ;
p_out(v_sn).col2 := 'col2_'||to_char(v_sn)||p_arg2 ;
p_out(v_sn).col3 := 'col3_'||to_char(v_sn)||p_arg3 ;
END LOOP ;
END ;
END test_package ;
My java code is following, it doesn't work:
Class.forName ("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection
("jdbc:oracle:thin:@10.16.102.176:1540:dev", "scott", "tiger");
con.setAutoCommit(false);
CallableStatement ps = null;
String sql = " begin test_package.test_matrix( ?, ? , ? , ? ); end ; ";
ps = con.prepareCall(sql);
ps.setString(1,"p1");
ps.setString(2,"p2");
ps.setString(3,"p3");
ps.registerOutParameter(4,OracleTypes.CURSOR);
ps.execute();
ResultSet rset = (ResultSet) ps.getObject(1);
error message :
PLS-00306: wrong number or types of arguments in call to 'TEST_MATRIX'
ORA-06550: line 1, column 8:

Louis,
If I'm not mistaken, record types are not allowed. However, you can use object types instead. However, they must be database types. In other words, something like:
create or replace type ROW_ABC as object (
col1 varchar2(16),
col2 varchar2(16),
col3 varchar2(16 )
create or replace type MATRIX_ABC as table of ROW_ABC
/Then you can use the "ARRAY" and "STRUCT" (SQL) types in your java code. If I remember correctly, I recently answered a similar question either in this forum, or at JavaRanch -- but I'm too lazy to look for it now. Do a search for the terms "ARRAY" and "STRUCT".
For your information, there are also code samples of how to do this on the OTN Web site.
Good Luck,
Avi.

How to use nested table types with XDK

Im using Oracles XDK (xml development kit) to create xml-documents from data in database.4
Problem: I need to use nested tables but when trying to create nested table types I get error: A Table type may not contain a nested table type or VARRAY.
Hope I make myself clear! Are there any solutions or workarounds to this problem?
Help appreciated, thanks!

Jesper,
I asked similar question last year (search for Tapsell, you will see my posting). Under 8.1.7 the "nesting" seems restricted to one level down. Thus you cannot create a type using another object that itself includes a nested table. Under Oracle 9, against which most current examples seem based, this limitation is removed making things easier. Under 8.1.7 the workaround I have used is to use the CAST syntax. This is not as neat, but it works.

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...

Perhaps Parallel Query/DML might give some relief.

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.

Need help for record/table type

Hi, All,
I have a table below and I need to use a procedure/function to return a list of values out and use anther procedure (array with multiple values in) to update the database. Could someone please give some examples?
Here are my questions:
1.     I need to create a user_defined_type to hold the list of info (array like, with more fields). Does the table type with %rowtype do that? If not, Could you please give an example?
2.     if I do
SELECT * INTO V_test(1) FROM PREO_profile
where user_id = '1';
can the 3 records of user_id 1 all be selected in the V_test table? If not, could you please tell me what to do?
Thanks a lot.
PREO_profile:
User_id     N_id          M_id
1      11 111
1      22 222
1      33 333
2      11 111
2      22 222
2      33 333
CREATE OR REPLACE PROCEDURE test_updatePro
(user_id in varchar2,
profile_info out T_Test)AS
Type T_Test is table of PREO_profile%rowtype
index by binary_integer;
V_test T_Test;
BEGIN
     SELECT * INTO V_test(1) FROM PREO_profile
     where user_id = '1';
END;

Here is one approach. This works in 9iR2. It's worth noting this functionality is evolving quite fast. Consequently, stuff that works in 9.2 may well not work in 9.0.1 and can probably be done much neater in 10g.
Let's start by creating some tables....

Table created.
SQL> INSERT INTO preo VALUES (1, 11, 111);
1 row created.
SQL> INSERT INTO preo VALUES (1, 22, 222);

1 row created.
SQL> CREATE TABLE neo_preo AS SELECT * FROM preo WHERE 1=0;

Building an object of nested table types

Hi,
Looking for suggestions for the following.
I have a procedure with 4 table types.
They are in a hierarchical order so that 4 is the child of 3, 3 is the child of 2 and 2 is the child of 1.
One of the columns of table 1 is a table type holding all the child records from table 2,
One of the columns of table 2 is a table type holding all the child records from table 3,
One of the columns of table 3 is a table type holding all the child records from table 4,
I have 4 cursors that pull out all of the data to populate each of my 4 table types.
I am trying to figure out how to nest my fetches to populate all of my table types to create a single object that hold all of my data.
It’s a table of a table of a table of a table.
Column 3 of table 1 holds table 2
Column 3 of table 2 holds table 3
Column 3 of table 3 holds table 4
I’ve tried creating my procedure like this (pseudo code)
declare
tab_1 tab_1_type;
tab_2 tab_2_type;
tab_3 tab_3_type;
tab_4 tab_4_type;
cursor get_tab_1 is
select col1, col2, tab_2 – added the table type for the child records
from data_table_1
cursor get_tab_2(tab_1_pk in number) is
select col1, col2, tab_3 – added the table type for the child records
from data_table_2
where tab_2_fk = tab_1_pk
cursor get_tab_3(tab_2_pk in number) is
select col1, col2, tab_4 – added the table type for the child records
from data_table_3
where tab_3_fk = tab_2_pk
cursor get_tab_4(tab_3_pk in number) is
select col1, col2, col3
from data_table_4
where tab_4_fk = tab_3_pk
begin
open get_tab_1;
loop
open get_tab_2
loop
open get_tab_3
loop
open get_tab_4(tab_3_pk);
bulk collect get_tab_4 into tab_4;
close get_tab_4;
fetch get_tab_3 into tab_3;
tab_4:= null;
exit when get_tab_3 %notfound;
end loop;
close get_tab_3;
fetch get_tab_2 into tab_2;
tab_3:= null;
exit when get_tab_2 %notfound;
end loop;
close get_tab_2;
fetch get_tab_1 into tab_1;
tab_3:= null;
exit when get_tab_1 %notfound;
end loop;
close get_tab_1;
l_return := tab_1;
end;
The above won’t work because once the cursor is opened the child tables will be assigned values of null before they have had a chance to populate from the nested fetches.
It’s almost as if I need to execute the fetch and update the extra columns afterwards somehow, something like:
fetch get_tab_3 into tab_3;
tab_3.col3 := tab_4;
tab_4 := null;
end loop;
close get_tab_3;
can I do that?
Also the above seems very cumbersome. If there is a more elegant way of building up this object I’d like to hear it.
Cheers

Public Synonyms for Nested Tables - Insertion Problem

Hi,
we are facing a problem during implementation. Our DB set up
is , we will be having two schema named OWNR and COPY.
In the schema, OWNR we have to create all the tables,
types,procedures, packages and obj.....This schema will have
both DDL and DML privileges.
In the schema, COPY we are not supposed to create any tables,
objects. We have to create public synonyms for all the tables,
types, procedures... in OWNR and grant ALL privilege to the
schema COPY.The schema, COPY will have only DML privileges.
The problem is we have some nested tables in our application.
When I try to insert into the synonym which is created for the
nested table, it is not allowing me to insert..The whole
implementation is stucked..Please help.The scripts are given
below.......
We have a type name SITA_ADDRESS_TY which is used by the nested
table SITA_ADDRESSES_NT.Script used for creating the Type,Nested
table,Table, Public Synonym and granting all privilege to these
types and tables are
CREATE OR REPLACE TYPE SITA_ADDRESS_TY AS OBJECT (

OWNR.SITA_ADDRESSES_NT
Why is it so??. Even though I have a synonym for
SITA_ADDRESSES_NT, it is not referencing the synonym but instead
refer the OWNR.SITA_ADDRESSES_NT
Because of this when I try to insert into ums_sita_address(in
schema COPY), it is giving the following error,
SQL> insert into ums_sita_address values
('EK','EK','DXB',SITA_ADDRESSES_NT());
insert into ums_sita_address values
('EK','EK','DXB',SITA_ADDRESSES_NT())
ERROR at line 1:
ORA-00932: inconsistent datatypes
But when the same connect to OWNR and try to insert with the
same stmt, it is inserting...
Our middle tier can connect only to COPY schema alone..Is there
anything to be done in the DBA side to achieve this??.
Please help from your valuabe experience...Or can you ask your
collegues if they have got a soln to this probs..Our
implementation team is stucked with this...
Thanks
Priya

Hi
I am not sure but maybe you need to use this command:
SQL> insert into ums_sita_address values
('EK','EK','DXB',SITA_ADDRESSES_TY());
SITA_ADDRESSES_TY() instead SITA_ADDRESSES_NT

Why is it so??. Even though I have a synonym for
SITA_ADDRESSES_NT, it is not referencing the synonym but instead
refer the OWNR.SITA_ADDRESSES_NT
Because of this when I try to insert into ums_sita_address(in
schema COPY), it is giving the following error,
SQL> insert into ums_sita_address values
('EK','EK','DXB',SITA_ADDRESSES_NT());
insert into ums_sita_address values
('EK','EK','DXB',SITA_ADDRESSES_NT())
ERROR at line 1:
ORA-00932: inconsistent datatypes
But when the same connect to OWNR and try to insert with the
same stmt, it is inserting...
Our middle tier can connect only to COPY schema alone..Is there
anything to be done in the DBA side to achieve this??.
Please help from your valuabe experience...Or can you ask your
collegues if they have got a soln to this probs..We are stucked
with this...
Thanks
Priya

Hi
I am not sure but maybe you need to use this command:
SQL> insert into ums_sita_address values
('EK','EK','DXB',SITA_ADDRESSES_TY());
SITA_ADDRESSES_TY() instead SITA_ADDRESSES_NT

Nested table type in object view on 8.1.7

Object views seem to be the ideal way to deliver XML datagrams from database queries with nested data.
I need to create a datagram that contains nested data within another nested set of data eg. a family has many people, each person may have many hobbies.
The following code taken from Oracle documentation would create the Types I need, but this does not work on 8.1.7 (gets PLS-00534 error). Can someone advise if nested tables within a table type is a new Oracle 9 feature?
CREATE TYPE project_t AS OBJECT
( projname VARHCAR2(20)
, mgr VARHCAR2(20));
CREATE TYPE nt_project_t AS TABLE OF project_t;
CREATE TYPE emp_t AS OBJECT
( ename VARCHAR2(20)
, salary NUMBER
, deptname VARHCAR2(20)
, projects nt_project_t);
CREATE TYPE nt_emp_t AS TABLE OF emp_t;
CREATE TYPE dept_t AS OBJECT
( deptno NUMBER
, deptname VARHCAR2(20)
, emps nt_emp_t);
Thks, Matt. (asked same question in XML forum but maybe more appropriate here).

Matthew,
Value-based multi-level collections, such as the one you have here, were not supported in 8.1.7. You have two choices:
1. Upgrade to 9i to take advantage of value-based multi-level collections (see http://download-west.oracle.com/otndoc/oracle9i/901_doc/appdev.901/a88878/adobjbas.htm#462243), type inheritance, type evolution and other new features.
2. Use REFs in 8.1.7 to build a reference-based multi-level collections (see http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/appdev.817/a76976/adobjdes.htm#446229).

ROWNUM equivalent for Nested Tables?

Is there an equivalent to the ROWNUM pseudocolumn for a nested table such that something like this...
WITH driver_data AS
(SELECT 1 AS id, sys.dbms_debug_vc2coll('a','b','c') AS val FROM dual
UNION ALL
SELECT 2 AS id, sys.dbms_debug_vc2coll('x','y','z') AS val FROM dual)
SELECT t1.id,
--t2.rownum as pos,
t2.column_value AS val
FROM driver_data t1,
     TABLE(t1.val) t2 ;
ID     VAL
1     a
1     b
1     c
2     x
2     y
2     z...would return something like this...
ID     VAL POS
1     a      1
1     b      2
1     c      3
2     x      1
2     y      2
2     z      3

Help needed for nested table

Hi ,
I have a function which returns nested table as result .The nested table can sometimes be null.So when i reference the first and last value for a loop, when table is null , then i am getting numeric value error .So i added a check on the nested table as below
if n_table is empty then
exit;
end if;
for i in n_table.first ..n_table.last
loop
select count(1) into_count
from x where rate=n_table(i);
end loop;
Now iam getting a message as" DANGLING NOT NULL OF".Though it gets compiled .iam getting everytime when i first compile it .Please let me know what should i add to prevent this

Null and empty are two different things. Also please post the complete error message.
Notice the difference between
DECLARE
    v_tab INTEGER_TT;
BEGIN
    IF v_tab IS NOT NULL THEN
        FOR i IN v_tab.FIRST..v_tab.LAST LOOP
            DBMS_OUTPUT.PUT_LINE('Loop iteration ' || i);
        END LOOP;
    END IF;
END;and
DECLARE
    v_tab INTEGER_TT := INTEGER_TT();
BEGIN
    IF v_tab IS NOT EMPTY THEN
        FOR i IN v_tab.FIRST..v_tab.LAST LOOP
            DBMS_OUTPUT.PUT_LINE('Loop iteration ' || i);
        END LOOP;
    END IF;
END;

XML Type - ExtractValue for Nested Tables

Hi all,
PROCEDURE TESTING
IS
v_xml CLOB := '<EMPLOYEE><RECORD><EMPID>12</EMPID><EMPNAME>ROCK</EMPNAME></RECORD><RECORD><EMPID>13</EMPID>13<EMPNAME>PETER</EMPNAME></RECORD><RECORD><EMPID>14</EMPID><EMPNAME>JOHN</EMPNAME></RECORD></EMPLOYEE>';
BEGIN
FOR i IN
(SELECT EXTRACTVALUE (indv_xml, 'RECORD/EMPID') eid,EXTRACTVALUE (indv_xml, 'RECORD/EMPNAME') ename
FROM (SELECT VALUE (v) indv_xml
FROM (SELECT XMLTYPE (v_xml) main_xml
FROM DUAL),
TABLE
(XMLSEQUENCE
(EXTRACT
(main_xml,
'EMPLOYEE/RECORD'
) v))
LOOP
insert into employee values(eid,ename);
END LOOP;
END;
Now i have the xml like this:-
'<EMPLOYEE>
<EMPTYPE>
<TYPEID>121</TYPEID>
<ROW><EMPID>12</EMPID><EMPNAME>ROCK</EMPNAME></ROW>
<ROW><EMPID>13</EMPID>13<EMPNAME>PETER</EMPNAME></ROW>
</EMPTYPE>
<EMPTYPE>
<TYPEID>122</TYPEID>
<ROW><EMPID>14</EMPID><EMPNAME>JOHN</EMPNAME></ROW>
</EMPTYPE>
</EMPLOYEE>'
In this case, I have populate into two tables first EMP_TYPE (typeid - PK) and EMPLOYEE(EID,ENAME,TYPEID -FK)...
Pls provide me some sample code.
Thanks
