DML operations on table

Hi,
I need to find which all procedures/function/package performs particular operation on a table.
Like, if table is SCOTT.EMP, need to find which all objects insert data into it / or delete from it / or updates it.
Is there any views available for this? or what can be done to get this details.
Thanks!

Thanks jgarry, u understood correct.
We don't want to do logging or auditing, we just need to find which all objects do insert to particular tables.(this is needed for some performance and benchmark activities) Usually a query to user_source could help to find, but it may not work if there are newline or extra spaces in SQL statement in object.
Not all DML statements that operate against the DB reside within the DB.
SQL can reside in OS files external to the DB.
I know only 3 way to ensure all DML is "captured"
1) REDO log files
2) SQL_TRACE files; assuming every session is traced.
3) AUDIT

"cannot perform a DML operation inside a query" error when using table func

Query performance on same table with many DML operations

Hi all,
I am having one table with 100 rows of data. After that, i inserted, deleted, modified data so many times.
The select statement after DML operations is taking so much of time compare with before DML operations (There is no much difference in data).
If i created same table again newly with same data and fire the same select statement, it is taking less time.
My question is, is there any command like compress or re-indexing or something like that to improve the performance without creating new table again.
Thanks in advance,
Pal

Try searching "rebuilding indexes" on http://asktom.oracle.com. You will get lots of hits and many lively discussions. Certainly Tom's opinion is that re-build are very rarley required.
As far as I know, Oracle has always re-used deleted rows in indexes as long as the new row belongs in that place in the index. The only situation I am aware of where deleted rows do not get re-used is where you have a monotonically increasing key (e.g one generated by a seqence), and most, but not all, of the older rows are deleted over time.
For example if you had a table like this where seq_no is populated by a sequence and indexed
seq_no         NUMBER
processed_flag VARCHAR2(1)
trans_date     DATEand then did deletes like:
DELETE FROM t
WHERE processed_flag = 'Y' and
      trans_date <= ADD_MONTHS(sysdate, -24);that deleted the 99% of the rows in the time period that were processed, leaving only a few. Then, the index leaf blocks would be very sparsely populated (i.e. lots of deleted rows in them), but since the current seq_no values are much larger than those old ones remaining, the space could not be re-used. Any leaf block that had all of its rows deleted would be reused in another part of the index.

How to know which DML operation is taking place on a table within a procedu

Hii all,

TNS for Solaris: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - ProductionHow to find what DML Operation is taking place on a particular table within a procedure??
For suppose I've the below procedure
create table r_dummy
name varchar2(4000),
emp_id number
Create or replace procedure r_dummy_proc
p_name          in     varchar2,

               dbms_output.put_line('Successfully updated employee name');
          end if;
End;Here from the code I can identify that an update operation is taking place on table 'R_DUMMY'
But how to find that without actually viewing the code?? I've hundreds of procedures in my DB and would like to find what DML is taking place on which table and in which procedure.
Please help with some suggestions.

DML operations improves perfomance on a Partioned Table?

Hi
We have a simple table (non-partitioned) and we do normal DML operations on it. If we convert that table into 5 partitions then does DML performance improves on it by 5times? To be very specific will READ and WRITES on table will improve? if YES than to which extent. *(considering Table size in TB)*. DB is 11g R2.

CKLP,
I populated a table in my test environment called test with 10 columns and 7 million records.
its structure is
col1..col5 are of data type number and are locally indexed
col6..col 9 are of data type number (not indexed)
col 10 is of data type Date
table is partitioned on col10 by Range. (7 partition for a week (1 partition/day), 1million records in a partition)
when i inserted 7 million records (i.e one million record/partition). Avg insertion time/partition was 7.5 min. (I inserted records individually in a partition)
Then I created another table test2 with same no. of columns Indexed and equal amount of records. But increased the no. of partitions. 4 partitions/day 28 partitions for week
When I inserted 7 million records (one million records/ 4 partitions), Avg insertion Time was 7.1 min. (I inserted records individually in these 4 partition at a single time)
Insert into test values(...) format was used. and now i know Parallelism can't be used on this format.
So the point to discuss here is "why did not I achieve a better Insertion Time when i divided a daily partition to 4 partition per day". OR " How can i improve insertion time in such scenarios"

Date Field Displaying and DML Operations

Hi all,
I have an issue with displaying and updating date columns that I'm hoping someone can assist me with.
I'm using APEX 3.0.1.
I have a Form page with a number of fields sourced from one database table that are being populated by an Automatic Row Fetch On Load - After Header.
The Item P6_MONTHFOR is stored as a Date datatype in the table and displayed on the form using the Date Picker (use Item Format Mask). I have a Format Mask set as 'MON-RR'. I want to ensure that the last day of the month is saved back to the database table so have been trying various calculation techniques to try and achieve this but am experiencing a variety of SQL errors!
I have tried using LAST_DAY(:P6_MONTHFOR) in the Post Calculation Computation, or as a separate Computation After Submit.
I have also tried having P6_MONTHFOR as a hidden column and using display Items and then trying Item calculations to then update the value of P6_MONTHFOR column prior to DML operations but to no avail.
The only DML operations allowed on these rows are DELETE and UPDATE and I'm using an Automatic Row Processing (DML) On Submit - After Computations and Validations process to control these operations.
Any help or suggestions greatly appreciated :-)
Kind Regards,
Gary.

the function LAST_DAY is a date function, expecting a date as input. Since it is all web, the values of items are as string/varchar2. In order to use date-function, you have to first make it a date with to_date() with the format-mask (DD-MON-RR).
In my opinion Dates are still tricky, it would be great if ApEx would have a DV() function, next to the V() and NV() functions, It is in ApExLib (of Patrick Wolf)

DML on multiple tables in one Page

Hi,
Requirement is there are 6 tables.
Depends on the input parameter we need to perform DML operations on the tables.
Is there any way to build VO(Based on EO) dynamically linked to a table and performs DML.
If this is possible we pass table name as parameter, and perform DML on that Table.
Thanks
JP

Hi,
You can create a PL/SQL procedure for performing DML operating and your logic inside that.
Later you can use CallableStatement to execute that procedure.

Log Miner is finding DDL for "new" tables, but also DML for "older" tables.

oracle 10.2.0.5.0 Standard Edition
(at some point in the past it was "downgraded" from enterprise edition).
It's making me crazy, i create a table then insert/update rows. Log miner only shows me the create.
However, if i do insert/update on an "older" table, i see the DML. The tables are in the same tablespace, both logging, and the database is forcing logging.
I'm out of ideas, and input would be appreciated.
thanks!

apparently this is an issue with the database configuration and not log miner. I ran the same test against the prodcution database and got both the DDL and DML. I used exactly the same test script including the logminer "setup" , obviously changing the name of the log files and the name of a directory.

ORA-14551: cannot perform a DML operation inside a query

I have a Java method which is deployed as a Oracle function.
This Java method parses a huge XML & populates this data
into a set of database tables.
I have to call this Oracle function in a unix shell script using sqlplus.
Value returned by this function will be used by the shell script to decide
what to do next.
I am calling the Oracle Java function as follows in the shell script:
echo "SELECT XML_TABLES.RUN_XML_LOADER('$P1','$P2','$P3','$P4') FROM DUAL;\n" | sqlplus $DB_USER > $LOG
This gives error - "ORA-14551: cannot perform a DML operation inside a query".
If I have to add a AUTONOMOUS_TRANSACTION pragma to this Java function,
where to I add it considering, that the definition of the function is in a Java class.
Can we do it in call spec?
create or replace package XML_TABLES is
function RUN_XML_LOADER(xmlFile IN VARCHAR2,
xmlType IN VARCHAR2,
outputDir IN VARCHAR2,
logFileDir IN VARCHAR2) RETURN VARCHAR2 AS
LANGUAGE JAVA NAME 'XmlLoader.run
(java.lang.String, java.lang.String, java.lang.String, java.lang.String)
return java.lang.String';
end XML_TABLES;
If not is there any other way to acheive this?
Thanks in advance.
Sunitha.

If I have to add a AUTONOMOUS_TRANSACTION pragma to this Java function,You'd have to write a PL/SQL function that calls the JSP. But I would caution you about using that pragma. It does introduce tremendous complexity into processing.
As I see it you only need a function to return the result code so why not use a procedure with an OUT parameter?

Of course Yoann's suggestion of using an anonymous block would work too.

DML operations not getting logged

Hi,
I am wanting to collect the stats on the tables on my DB for which I want the DML activities to be populated in the USER_TAB_MODIFICATIONS table. The monitoring on all the tables in the schema has been set to ON. But i still see no records inside the USER_TAB or DBA_TAB_MODIFICATIONS table.
I can always try executing the dbms_stats.flush_database_monitoring_info for getting this table populated. But I wanted to first know why is this table not getting populated thru the DB processes? And incase any DB level setting is preventing it from getting inserted in the USER_TAB_MODIFICATIONS table, I am not sure if executing the dbms_stats.flush_database_monitoring_info would help me.
Kindly advice.
Thanks in advance.

I am not able to guess the reason behind this. Kindly help.

DML Operations in Stored Function

Hi,
I have used Update Statement in a function. Which is giving an errror (ORA-14551: cannot perform a DML operation inside a query).
Can I use DML operations in a stored function ?
(I need help on locking master/transaction tables, i.e if a one user locks a master another user should not get modify access to the master/transactions).
Thanks
Ramesh Ganji

Someone who obviously din't read my previous post in this thread. You should pay attention, programming is all about the details.
ORA-14551: cannot perform a DML operation inside a query).Then it obviously does more than just "returns a Table Type object". Why are you doing DML in a function?
PLS-00653: aggregate/table functions are not allowed in PL/SQL scopeWe can only call pipelined functions from SQL queries. So you'll have to ditch the DML or make it an autonomous transaction. Be very careful if you adopt the latter approach.

Why we cannot perform DML operations against complex views directly.

hi
can any tell me why we cannot perform DML operations against complex views directly.

Hi,
It is not easy to perform DML operations on complex views which involve more than one table as said by vissu. The reason being you may not know which columns to be updated/inserted/deleted on the base tables of the views. If it is a simple view containing a single table it is as simple as performing actions on the table.

Ref:Logging the DML operations on a schema

Hello,
I want to log the DML operations on our Master Schema(This schema is accessed by 4-6 applications apart from there own application schemas). I want to log the DML operations done by x.application. Is there any easy way to do it. One solutions is writting the triggers on each table of Master schema and inserting the transactions into audit_schema(it is replica of master schema). Is there any other way to do it. Any solution for this issue is appreciated. Thanks in advance.

DML operations on a Replicated Object when it is in QUIZED State.

Hi,
How do we do DML operations on a Replicated object(Multi-Master Replication) when the object is in QUIZED State.
As such my intenttion is to bring the Replication in a QUIZED State and then do some DML then bring up the Replicator and allow it to sync the Database.

Hi Anita,
Thank you so much for patiently explaining me about issues on Replication.
Now, let me explain my objective. We are about to implement Oracle 8.1.6 Multi Master Replication. As a Fall back mechanism management is so concerned that "if anything goes wrong in Replication, how do we prevent the "stopshow" from carrying out the normal transaction till the issues gets settled.
To achieve this objective, we are doing some investigation on this issue. As i am quite new to Oracle Replication I thought there is no way that i could do this in a very short "window" period.
I tried to stop the Replication using the suggested method it worked well. Meaning i am able to do the DML transaction. Now the problem is when we decide to bring up the system back to Replication. How do we go doing that. As i thought that the DBMS package that resumes the replication would do the "sync" on both sides of the Replication. But it is not happening.
I referred to the Oracle documentation on Replication and was quite eager to use the package DBMS_RECTIFIER_DIFF.DIFFERENCES and DBMS_RECTIFIER_DIFF.RECTIFY procedures.
But i am yet to test this. If this works out for a specific table. Then my plan is to deploy a mechanism where in b4 i start the replication i would execute these packages for all the replicated tables.
Hope you now understand what i intend to do and Pls advise me if i am on the right track on reaching my goal.
Thanx in advance.
Senthil.

How to Track DDL and DML Operations happening in Backend into Log Files....

Hi I have one requirement for Tracking the DDL And DML Operation happening in Backend once the user Inserts or Updates any Table.How to Implement the same can anyone proviode the code for the same.
Ex: I have multiple tables in my database if any user fires the DDL or DML it should make entry in the Log file as
Name of the Table Operation Timestamp
X Insert DD-MM-YYYY HH24:MM:SS
Y Update DD-MM-YYYY HH24:MM:SS
Z Delete DD-MM-YYYY HH24:MM:SS
L Select DD-MM-YYYY HH24:MM:SS
Is it Possible to Develop it through Procedure,Function or Package,please give me Idea,,,,,

Please do not post same question in multiple forum. How to Track DDL and DML Operations happening in Backend into Log Files....
What's wrong with the answers posted in the above forum ? Do you go through the "AUDIT" option as suggested in the above post by various members ?
