DEQUEUE_MSGID column in a queue table

There are three msgid-related columns in a queue table:
MSGID, CORRID, DEQUEUE_MSGID
I know the meaning of the columns MSGID and CORRID. But what is the column DEQUEUE_MSGID for?

Adding ne w column to advnaced queue

hi everybody,
I wanted to add new column to advanced queue already in production, is it advisable? and if yes how can I do it?
thanks in advance

Hello
There is no way to add a column to a queue table. Eventhough you can perform an ALTER TABLE statement and add a column to a queue table it is never supported and could result in unexpected behaviors.
When you enqueue a message you have the option to use "user_property" for having the additional data if needed. Take a look at the below:
DBMS_AQ.ENQUEUE (
message_properties IN message_properties_t,
payload IN "<ADT_1>",
TYPE message_properties_t IS RECORD (
user_property SYS.ANYDATA DEFAULT NULL
Or you can even have your payload contain the additional column and you populate this during enqueue via a an AQ transformation. The application can track the message based on either the user_property or by referring to the additional column in the payload (USER_DATA column in queue table).
These are the supported methods. If you still need to have a column then you would need to maintain a seperate table with the message id as the key column and required additional column so that each message can be referred correctly.

Messages are in READY state in QUEUE TABLE but in AQ$ QUEUE TABLE messages are in PROCESSED State

HI All,
   We create a brand new oracle multi-consumer queue. We have en-queued the messages into the queue and are processed successfully.
   But when we checked the STATE Column of the messages in the queue table it was showing as "0". But it is showing as "PROCESSED" in the
   AQ$<QUEUE_TABLE> msg_state column.
We are unable to figure out why there is a mismatch. Can any one help us ?
Regards,
Hari P.

Hello,
the column value AQ$<QUEUE_TABLE>.MSG_STATE = 'PROCESSED' corresponds to column value <QUEUE_TABLE>.STATE = 2
(see definition of view AQ$<QUEUE_TABLE for the DECODE statement).
In your case you see a value of STATE = 0 instead of STATE = 2. Is this correct ? The value 0 corresponds to a state "READY" (the delay
is gone and the message is ready for dequeuing).
The AQ documentation says: "After the specified delay, the message is in the READY state and available for dequeuing."
Normally, you cannot see the processed data in your AQ because the enqueued data will be deleted after
successful dequeuing. You wrote that they were processed successfully.
Kind regards,
WoG

Select from a queue table with SYS.AQ$_JMS_MAP_MESSAGE type

We are using the SYS.AQ$_JMS_MAP_MESSAGE type for our queue so that we can access the queue using plsql as well as java (via jms). The queue table that gets created contains a column user_data that is of the above type. This type has two columns BYTES_RAW and BYTES_LOB which I assume contains the data. Is there a way in sql (or in plsql) to get access to the data. Also, we are retaining the messages after they have been consumed (from an audit standpoint) and might need access to the data.
Thank you
Navin

yes, i understand how to describe something...
my question is how to get a list of properties.
this data type has get functions that take the name of a property. now how do i know that property name to get it?

Queue Table = Queue Mapping

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

maybe the problem is storage clause, can you help me ?
null

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.

Dropping queue table

hi
I am tryin to drop a schema devj2ee with the following command:

DLS_AQ_QUEUE TABLE
I hope you have any further tricks to try on this.

Error while dropping/creating new queue table

Hi,
I am trying to modify an existing AQ setup. In the process, I had to remove a queue and redirect all its subscriptions to another queue.
I get an oracle "sequence does not exist" while trying to drop the queue table. The sequence of operations that I am carrying out is:
disable propagation schedule
unschedule propagation
stop queue
drop queue
drop queue table
The error occurs when the drop statement is executed.
I tried restoring the existing configuration, but got the same error message while trying to add a subscription.
Could you help me with this problem? What am I missing here?
Thanks,
Anupama

In what version of Oracle?
I see a couple of problems assuming you are working with a currently supported version:
1. Never grant CONNECT to anyone: Ever. Grant CREATE SESSION.
2. GRANT CREATE TABLE to AQ;
Go to Morgan's Library at www.psoug.org and look at AQ Demo 1. You should have no problem cutting and pasting your way to where you are trying to go.

Find duplication values from multiple columns in a big table

Hi All,
I am working on a 11gR2 database in linux. i want to display record that have duplicate values in 2 columns.
1. Table Structure :-
CREATE TABLE A
ID NUMBER(10),
F_NAME VARCHAR2(100 BYTE),
L_NAME VARCHAR2(100 BYTE)
2. Sample Data:-
Insert into A
(ID, F_NAME, L_NAME) Values (1,'TONY' ,'SUMIT');
Insert into A
(ID, F_NAME, L_NAME) Values (2,'SUMIT' ,'KEITH');
Insert into A
(ID, F_NAME, L_NAME) Values (3,'NORA','SMITH');
Insert into A
(ID, F_NAME, L_NAME) Values (4,'APRIL','TONY');
Insert into A
(ID, F_NAME, L_NAME) Values (5,'ROSS','TAM');
ID F_NAME L_NAME
1 TONY SUMIT
2 SUMIT KEITH
3 NORA SMITH
4 APRIL TONY
5 ROSS TAM
4. My requirement is i need display IDs that it's F_NAME or L_NAME has duplication in F_NAME or L_NAME columns.
The result should be
ID
1 reason: F_NAME (TONY) equals to L_NAME of record 4, L_NAME (SUMIT) equals to F_NAME of record 2
2 reason: F_NAME (SUMIT) equals to L_NAME of record 1
4 reason: L_NAME (TONY) equals to F_NAME of record 1
record 3, 5 aren't in the result because there is no duplication in F_NAME or L_NAME columns for NORA,SMITH, ROSS, TAM
The table contains 10 million records, i really need to consider the performance.
kindly suggest me the solution

Note: Forum members please suggest better approach to this -- below.. convert into SQL :)
I know I will be opposed by many people in this forum for posting such in-efficient solution.
But trying to learn along with you.. its an interesting problem which must deal with all rows vs all rows to get all combinations.
But I am still thinking how to write it in SQL, probably will learn from this post after we receive some good SQL solution for the code what I am currently doing now.
step 1: created a table B similar to table A and added a column reason

Problem with Queue Table while dropping schema

Hi,
I want to DROP a schema, but it gives the following error while trying to drop it:
ORA-00604: error occurred at recursive SQL level 1
ORA-24005: must use DBMS_AQADM.DROP_QUEUE_TABLE to drop queue tables
From TOAD, I found that no queue or queue_table exists in the database presently.
I'm using 10.2.0.2 RAC database.
Can anyone help me to drop the schema?
Thanks in advance..
Regards,
Anjan

How to rename a column name in a table? Thanks first!

I tried to drop a column age from table student by writing the
following in the sql plus environment as :
SQL> alter table student drop column age ;
but I found the following error
ORA-00905: 缺少关键字 (Lack of Key word)
I have oracle enterprise edition 8.0.5 installed at windows 2000
thank you
And I want to know how to rename a column name in a table?
thanks

In Oracle 8i, your syntax would have worked. However, if I
recall correctly, in Oracle 8.0, you can't rename or drop a
column directly. One way to get around that problem is to
create another table based on a select statement from your
original table, providing the new column name as an alias if you
want to change the column name, or omitting that column from the
select statement if you just want to drop it. Then drop the
original table. Then re-create the original table based on a
select statement from the other table. Then you can drop the
other table. Here is an example:
CREATE TABLE temporary_table_name
AS
SELECT age AS new_column_name,
       other_columns
FROM   student
DROP TABLE student
CREATE TABLE student
AS
SELECT *
FROM   temporary_table_name
DROP TABLE temporary_table_name
Something that you need to consider before doing this is
dependencies. You need to make a list of all your dependecies
before you do this, so that you can re-create them afterwards.
If there are a lot of them, it might be worthwhile to do
something else, like creating a view with an alias for the
column or just providing an alias in a select. It depends on
what you need the different column name for.

How to select even the column names of a table?

Hello All,
Is there a way to select even the column names of a table in the select statement?
My select from a table (say X) is in a SQL* Plus script that gets invoked by application tier and displays data in the application tier window. User's can then copy the data into a spreadsheet and do their processing. However, I need to give them the column names too along with the data.
Thanks,
Chiru

If there is a middle tier that is selecting and
displaying the data, and that's what the users are
copying from, the middle tier would have to address
its presentation of the data to allow users to
include column names. If this is a common task, the
application should probably be modified to give users
the option of downloading the data in a spreadsheet
directly rather than forcing them to copy and paste
data.Thanks for the reply.
The users don't have to copy paste. The application tier has an options in the "Tools" menu item which allows them to copy the entire output to a file (in my case a txt file which is a pipe delimited). Then they have to do text to columns to get the data into each column of the spreadsheet. I could have directly called the stored procedures from the application tier and created ".csv" files and FTP'd them to the user's folders. However, I am having to go this round about because, I am not getting enough support from the LAN team in FTP'ing etc.
OK I'll think of another workaround.
Thanks,
Chiru

You have to put table name in Capital letters
Like
SELECT COUNT(1)
FROM user_tab_columns
WHERE table_name = 'EMP';
or
SELECT COUNT(1)
FROM user_tab_columns
WHERE table_name = UPPER('Emp');Regards
