Queue Table on Nested Objects
Queue Table with Nested Objects
I need to create a queue table based on nested object
These are my declarations
TYPE TESTATATYPE AS OBJECT (
CODICE VARCHAR2(5),
DESCRIZIONE VARCHAR2(30)
TYPE DETTAGLIOTYPE AS OBJECT (
CODICE VARCHAR2(5),
DESCRIZIONE VARCHAR2(30),
VALORE NUMBER
TYPE DETTAGLITYPE IS TABLE OF DETTAGLIOTYPE
TYPE MESSAGGIOTYPE AS OBJECT (
TESTATA TESTATATYPE,
DETTAGLI DETTAGLITYPE
Now i'm trying to create queue table
DBMS_AQADM.CREATE_QUEUE_TABLE(queue_table => 'MsgQTab',
queue_payload_type => 'MessaggioType',
storage_clause => 'NESTED TABLE
dettagli STORE AS dettagli_tab_Q',
sort_list => 'priority,enq_time'
but I get
ORA-00904: invalid column name
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 2012
ORA-06512: at "SYS.DBMS_AQADM", line 55
ORA-06512: at line 3
maybe the problem is storage clause, can you help me ?

Andrea,
You cannot currently use a nested table even as an embedded object within a message payload.
However, you can create an object type that contains one or more VARRAYs, and create a queue table that is founded on this object type. I guess this might be the problem you are facing.

As i understand it, having a queue table of same object type as the queue gives benefit of message peeking, better auditing & debugging capabilities. Does this mean if i modify the object type to add/drop a column, i need to drop/recreate the queue table ?
Other approach could be to use RAW or XMLTYPE as payload. Here many queues could map to one queue table.
What are key design criterion or pros/cons in choosing one of these approaches ? Any guidelines or best practices in this regard ?As i understand it, having a queue table of same object type as the queue gives benefit of message peeking, better auditing & debugging capabilities. Does this mean if i modify the object type to add/drop a column, i need to drop/recreate the queue table ?Yes, this would mean you have to drop/recreate the queue
Other approach could be to use RAW or XMLTYPE as payload. Here many queues could map to one queue table. RAW queues - you cannot specify rules/conditions on the message content
XMLTYpe queues - this will solve the problems you listed above. However, in 9.0 - you have to create an ADT with an embedded XMLType to use these.
In 9.2 - you can create the queue table with SYS.XMLTYPE payload -

Edit message payload object without remove queue table
Hi, need ur help again,
Known that if we want to modify a message payload attribute (add,edit or delete), we will fail to do so if the message payload is used by existing AQ's queue table.

never mind, I put "/" at the end of the create statement that makes executing create table twice....Yep. If I'm writing a script, I tend to just stick with "/" for all my statements, including the SQL as well as the DDL, otherwise it can be confusing whether a ";" is needed or not or whether it will try and execute it twice like you found.
"/" works for all. -
Inserting into a doubly nested table through an object view
Can anyone give me an example of an INSTEAD OF trigger that will mediate an INSERT into a doubly nested table of an Object View? Is there syntax that will allow it?
Here's some code to demonstrate. Note that relational tables, not an object table, are used to store object instances:
create or replace type TInnerNestedTable
is table of varchar2(20)
create or replace type TOuterNestedTable
is table of TInnerNestedTable
create or replace type TMyObject
is object
id varchar2(20)
, tab TOuterNestedTable
create
table T_MY_OBJECT
id varchar2(20) not null
, primary key (id)
create
table T_MY_OBJECT_TAB_OUTER
id varchar2(20) not null
, outerIndex integer not null
, primary key (id, outerIndex)
, foreign key (id) references T_MY_OBJECT on delete cascade
create
table T_MY_OBJECT_TAB_INNER
id varchar2(20) not null
, outerIndex integer not null
, innerIndex integer not null
, innerValue varchar2(20)
, primary key (id, outerIndex, innerIndex)
, foreign key (id, outerIndex) references T_MY_OBJECT_TAB_OUTER on delete cascade
create or replace view V_MY_OBJECT
of TMyObject
with object identifier (id)
as
select t.id
, cast(multiset(
select cast(multiset(

where o.id = t.id

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? -

Hai,
Please any one explain me.In RMS publish a message through RIB means we check the queues of message in particular message family queue table
Example:
if "Store" Message family publish a message means we check the queue in "STORE_MFQUEUE"
likewise
In subscriber side ,if "Inventory adjustment" message family subscribe a message means where we have to check the queue.
Please share the views.Andrea,
You cannot currently use a nested table even as an embedded object within a message payload.
However, you can create an object type that contains one or more VARRAYs, and create a queue table that is founded on this object type. I guess this might be the problem you are facing. -
Null value in Nested table of nested table for xml guru Steve Muench
The procedure I am using takes xml document with nested levels and insert into single table using DBMS_XMLSave.insertXML.
I am able to insert into table without any error message but when I am selecting row from table, it is showing null values in all the column of nested table's inner nested table.
When I am removing nested table's nested table by replacing with object type, it is showing data of object type for the first occurance and ignoring the rest nested occurance.
Help is greatly appreciated.

Import tables with nested table : ORA-00600
In Oracle 9.2
Create object, type as table, and table with nested table (store as syms_ntab) are successfully.
Also its export.
In process of import on another server (also 9.2, 'fromuser=one touser=two') shows errors:

But for all that table is created and error occur on phase inserting strings.
What is this?
In Oracle 8.0.5 i perform similar operation without error.From Oracle error messages and codes manual:
ORA-00600 internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string]
Cause: This is the generic internal error number for Oracle program exceptions. It indicates that a process has encountered a low-level, unexpected condition. Causes of this message include:
* timeouts
* file corruption
* failed data checks in memory
* hardware, memory, or I/O errors
* incorrectly restored files
The first argument is the internal message number. Other arguments are various numbers, names, and character strings. The numbers may change meanings between different versions of Oracle.
Action: Report this error to Oracle Support Services after gathering the following information:
* events that led up to the error
* the operations that were attempted that led to the error
* the conditions of the operating system and databases at the time of the error
* any unusual circumstances that occurred before receiving the ORA-00600 message
* contents of any trace files generated by the error

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.>

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?

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.

IF I change column types from nested table to varray type, will it help?

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.

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)?

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 -
TYPE OR TABLE DEPENDENCY OF OBJECT TYPE (ORA-2303)

==================================================
TYPE OR TABLE DEPENDENCY OF OBJECT TYPE (ORA-2303)
==================================================
PURPOSE
Type이나 table의 dependency가 있는 type을 drop하거나 replace하고자
하면 ORA-02303 error가 난다. 이 error의 원인을 알아보도록 한다.
Explanation
Object의 attribute나 method를 수정하기 위해서는 object type을 drop하고 재생성
해야 한다. Type이나 table의 dependency가 있는 type을 drop하거나 replace하고자
하면 ORA-02303 error가 난다. Object type은 type (nested table 또는 VARRAY)
또는 object table로써 구체적으로 표현된다. 만약 data의 보존이 필요하다면
temporary table에 manual하게 옮겨놓아야 한다.
SQL Reference guide에 의하면 DROP TYPE FORCE 옵션은 recommend하지 않는다.
왜냐하면 이 옵션을 쓰게 되면 복구가 불가능하고 dependency가 있던 table들은
access하지 못하는 결과를 초래한다.
Example
아래의 query 1, 2, 3은 dependency을 확인하는 query문이다.
1. Find nested tables
select owner, parent_table_name, parent_table_column
from dba_nested_tables
where (table_type_owner, table_type_name) in
(select owner, type_name
from dba_coll_types
where elem_type_owner = '<typeOwner>'
and elem_type_name = '<typeName>');
2. Find VARRAYs
select owner, parent_table_name, parent_table_column
from dba_varrays
where (type_owner, type_name) in
(select owner, type_name
from dba_coll_types
where elem_type_owner = '<typeOwner>'
and elem_type_name = '<typeName');
3. Find object tables
select owner, table_name
from dba_object_tables
where table_type_owner = '<typeOwner>'
and table_type = '<typeName>'
and nested = 'NO';

<Note:69661.1>Hi Carsten,
Thanks for the sharp hint. It works.
However, when I create a table using the schema, it gives me this error:
varray DOC."LISTOFASSIGNEDNUMBER"."ASSIGNEDNUMBER"
ERROR at line 14:
ORA-02337: not an object type column
Here is the script:
CREATE TABLE CUSTOMMANIFEST (
ID NUMBER PRIMARY KEY,
DOC sys.XMLTYPE
xmltype column doc
XMLSCHEMA "http://www.abc.com/cm.xsd"
element "CustomManifest"
varray DOC."LISTOFMANIFESTPORTINFO"."MANIFESTPORTINFO"
store as table MANIFESTPORTINFO_TABLE
(primary key (NESTED_TABLE_ID, ARRAY_INDEX))
organization index overflow
varray DOC."LISTOFASSIGNEDNUMBER"."ASSIGNEDNUMBER"
store as table ASSIGNEDNUMBER_TABLE
(primary key (NESTED_TABLE_ID, ARRAY_INDEX))
organization index overflow
LISTOFASSIGNEDNUMBER itself is complexType and not sure where is the error....
You may note there are more than two hierachy/levels...
Thanks.
