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?

Unable To Select From SQL Server table with more than 42 columns
I have set up a link between a Microsoft SQL Server 2003 database and an Oracle 9i database using Heterogeneous Services (HSODBC). It's working well with most of the schema I'm selecting from except for 3 tables. I don't know why. The common denominator between all the tables is that they all have at least 42 columns each, two have 42 columns, one has 56, and the other one, 66. Two of the tables are empty, one has almost 100k records, one has has 170k records. So I don't think the size of the table matters.
Is there a limitation on the number of table columns you can select from through a dblink? Even the following statement errors out:
select 1
from "Table_With_42_Cols"@sqlserver_db
The error message I get is:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message [Generic Connectivity Using ODBC]
ORA-02063: preceding 2 lines from sqlserver_db
Any assistance would be greatly appreciated. Thanks!Not a very efficient and space friendly design to do name-value pairs like that.
Other methods to consider is splitting those 1500 parameters up into groupings of similar parameters, and then have a table per group.
Another option would be to use "vertical table partitioning" (as oppose to the more standard horizontal partitionining provided by the Oracle partition option) - this can be achieved (kind of) in Oracle using clusters.
Sooner or later this name-value design is going to bite you hard. It has 1500 rows where there should be only 1 row. It is not scalable.. and as you're discovering, it is unnatural to use. I would rather change that table and design sooner than later. -
How to create a table from an existing table with new column
Hi !
Please help me.
I want to create a table from an existing table with data and add two new column to the new table.
What will be the syntax?craete table new_table as select a.*, 'somevalue' new_col1, 'somevalue'
new_col2 from old_table a;Also there is a pitfall - newly created table will accept column type and precision from the select statement, so further you can be needed to modify columns
if you want to have VARCHAR2 instead of CHAR for example:
SQL> create table new_dept as select dept.*, 'New data' new_col from dept;
Table created.
SQL> desc new_dept
Name Null? Type
DEPTNO NUMBER(2)
DNAME VARCHAR2(14)
LOC VARCHAR2(13)
NEW_COL CHAR(8)
SQL> alter table new_dept modify (new_col varchar2(8));
Table altered.
SQL> desc new_dept
Name Null? Type
DEPTNO NUMBER(2)
DNAME VARCHAR2(14)
LOC VARCHAR2(13)
NEW_COL VARCHAR2(8)Rgds.
Didn't see michael's post - it reflects the fix for this problem using CAST.

How to assign tasks in Approval Workflow to a set of users selected from a Lookup table
Hi all,
I am new to Project Server and I am using Project Server 2013 On premises deployement. Please help me on how to achieve the below scenario:
I have a requirement where, the initial PDP will have 2 fields (Reviewers and Approvers), wherein the engineer himself will select who the reviewer and approver from the Lookup tables.
Now I have to start task process with these selected people for approval.
Say for example , engineer has selected Alice and Bob as 2 reviewers, then
In the workflow I have :
Start Task process with
Project Data: Reviewers (which is giving error as
[System.ArgumentException: AssignedTo at Microsoft.Activities.Hosting.Runtime.Subroutine.SubroutineChild.Execute(CodeActivityContext context) at System.Activities.CodeActivity.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager
bookmarkManager) at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation) ]
Then I tried logging the value of Project Data: Reviewers, It logged the value as Alice, Bob (which looks pretty good),
Then I tried assigning only 1 person as Reviewer, then also I get the same error.
So can anybody please tell me where I went wrong. Is it not possible to fetch the data from the values selected as Project Data from the Lookup tables ? If not then what is the workaround I can use to achieve this ?
Thanks,
ShankyHi Paul,
Yes I am using SP designer for Workflows. And yes, You were right, there was a mismatch in the names of AD account and the Lookup table, now with 1 person selected from the lookup table it is assigning the task properly. However with multiple selection,
it is failing.
As Robert mentioned, the fetched value is a text as "Alice, Bob", which makes 2 usernames as a single text. So when I try to assign a task to this group, which returns value as "Alice, Bob", workflow fails to find such AD user, as it
is an invalid value.
So is there any way I can seperate this out to form 2 different username ? I checked for string extraction function in th Workflow, but nothing helped me for this scenario.
Any input will be helpful.
Thanks,

Hi Guys,
I was just hoping to get your opinion on something.
I have a procedure in Production that is taking longer and longer to finish and sticks on one certain section of code.
The code is an INSERT into the main dimension table.
This same procedure runs fine on TEST and the section of code completes an awful lot quicker.
The traffic on Production is a lot heavier and there have been applications developed by people other than myself which SELECT from this dimension table. I'm assuming, based on the fact the code in Test and Production are identical, that this increased traffic could be eating up the bandwith and slowing the jobs.
So, I was thinking - if I create Views and let the other applications hit the views as opposed to the main table, will this help speed it up. I did this before on a Teradata platform using a 'dirty read' which worked quite well but Oracle doesn't seem to offer this option.
What do you guys think? Could this work or do I need to take a different approach.
Thank You.GerardMcL wrote:
I meant ordinary views.
I was wondering if there was a way of putting some locking code in or asking for a dirty read that would speed up the SELECT from the table?There is no such thing as a dirty read with Oracle -- Teradata, SQL Server, Sybase, IBM, etc., have different locking architectures where reads can block write and writes can block reads, and that is not an issue with Oracle.
If there's a query performance problem, which is what that will be if the SELECTs are slow, then if you could follow the following links, that will help diagnosis immensely:
[How to Post A Tuning Request|http://forums.oracle.com/forums/thread.jspa?threadID=863295&tstart=0]
And:
[When your Query takes too long|http://forums.oracle.com/forums/thread.jspa?messageID=1812597#1812597]
There is such as thing as stale reads, against Materialized Views, which are views that actually materialize and store the results of a query, and which then can subsequently be queried. -
SELECTing from a large table vs small table
I posted a question few months back about teh comparison between INSERTing to a large table vs small table ( fewer number of rows ), in terms of time taken.
The general consensus seemed to be that it would be teh same, except for teh time taken to update the index ( which will be negligible ).
1. But now, following teh same logic, I m confused why SELECTINg from a large table should be more time taking ("expensive" ) than SELECTing from a small table.
( SELECTing using an index )
My understanding of how Oracle works internally is this :
It will first locate the ROWID from teh B-Tree that stores the index.
( This operation is O(log N ) based on B-Tree )
ROWID essentially contains teh file pointer offset of teh location of the data in teh disk.
And Oracle simply reads teh data from teh location it deduced from ROWID.
But then the only variable I see is searching teh B-Tree, which should take O(log N ) time for comparison ( N - number of rows )
Am I correct above.
2. Also I read that tables are partitioned for performance reasons. I read about various partiotion mechanisms. But cannot figure out how it can result in performance improvement.

Can somebody please helpIt's not going to be that simple. Before your first step (locate ROWID from index), it will first evaluate various access plans - potentially thousands of them - and choose the one that it thinks will be best. This evaluation will be based on the number of rows it anticipates having to retrieve, whether or not all of the requested data can be retrived from the index alone (without even going to the data segment), etc. etc etc. For each consideration it makes, you start with "all else being equal". Then figure there will be dozens, if not hundreds or thousands of these "all else being equal". Then once the plan is selected and the rubber meets the road, we have to contend with the fact "all else is hardly ever equal". -

Get the Common from Two Internal Tables with same structure
Hi ,
I need to get the Common data from Two Internal Tables with same structure with using the looping method.
For e.g.

ITAB1 has values A,B,C,D,E,F
ITAB2 has values A,H,B,Y,O
Output at runtime should be : A,BHi mohit,
1. If u want to compare all fields,

then we can do like this.
2.
report abc.
data : a like t001 occurs 0 with header line.
data : b like t001 occurs 0 with header line.
loop at a.
LOOP AT B.
IF A = B.

Select count from large fact tables with bitmap indexes on them
Hi..
I have several large fact tables with bitmap indexes on them, and when I do a select count from these tables, I get a different result than when I do a select count, column one from the table, group by column one. I don't have any null values in these columns. Is there a patch or a one-off that can rectify this.
ThxYou may have corruption in the index if the queries ...
Select /*+ full(t) */ count(*) from my_table t
... and ...
Select /*+ index_combine(t my_index) */ count(*) from my_table t;
... give different results.
Look at metalink for patches, and in the meantime drop-and-recreate the indexes or make them unusable then rebuild them. -
Dynamic Select Query including Dynamic Tables with For all Entries
Hello everyone,
I need to create a select query which involves using of Dynamic Tables.
Suppose I have a dynamic table <d1> which consist of let say 10 records.
Now i need to make a select query putting data into another dynamic table <d2>
CONCATENATE keyfield '=' '<d1>' INTO g_condition SEPARATED BY space.
CONCATENATE g_condition '-' keyfield INTO g_condition.
SELECT * FROM (wa_all_tables-name) INTO CORRESPONDING FIELDS OF TABLE <d1>

Please help me on this....Short text
A condition specified at runtime has an unexpected format.
What happened?
Error in the ABAP Application Program
The current ABAP program "ZNG_CUSTOMWRITE" had to be terminated because it has
come across a statement that unfortunately cannot be executed.
Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_DYNAMIC_OSQL_SEMANTICS', was

Giving Error When Selecting From a Custom Table
There is a custom report 'Z*' which archives data.
In this report, while selecting data(needs to be archived) from a custom table 'Z*_T', giving runtime error in Production Server.
The select statement is written below :
*data izX like z_t occurs 1000 with header line._
*select * from z*t into table i_zX.*_
How can I change the select statement so that it will work properly?Sas..
From your example code it appears you are trying to use a wild card for both your dbtable and the internal table.
To do this, you will lilkely need to use a Field Symbol for the target internal table and your FROM will need to be a varible
FROM (dbtabname)
The ABAP Helps gives this example for the Select Table
DATA TABNAME(10).
DATA: BEGIN OF WA,
ID LIKE SCUSTOM-ID,
NAME LIKE SCUSTOM-NAME,
REST(134),
END OF WA.
TABNAME = 'SCUSTOM'.
SELECT * INTO WA FROM (TABNAME).
WRITE: / WA-ID, WA-NAME.

Select query on a table with 13 million of rows
Hi guys,
I have been trying to perform a select query on a table which has 13 millions of entries however it took around 58 min to complete.
The table has 8 columns with 4 Primary keys looks like below:
(PK) SegmentID > INT
(PK) IPAddress > VARCHAR (45)
MAC Address > VARCHAR (45)
(PK) Application Name > VARCHAR (45)
Total Bytes > INT
Dates > VARCHAR (45)
Times > VARCHAR (45)
(PK) DateTime > DATETIME
The sql query format is :
select ipaddress, macaddress, sum(totalbytes), applicationname , dates,
times from appstat where segmentid = 1 and datetime between '2011-01-03
15:00:00.0' and '2011-01-04 15:00:00.0' group by ipaddress,
applicationname order by applicationname, sum(totalbytes) desc
Is there a way I can improve this query to be faster (through my.conf or any other method)?
Any feedback is welcomed.
Thank you.
