Count DML operations

Hi Friends,
Can we count and analyze that how many DML operations/transactions been made in current session and on a particular table.
If yes then how ?
Thanks in advance...

Hi,
You can audit on table : http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_48a.htm#SQLRF01107

Two DML operations in one FORALL?

Hi all,
In 11g is it possible to make two dml operations in one Forall loop?
For example:
SQL> create table xx_test (col1 number, col2 number, col3 number);
Table created
SQL> create table xx_test1 (col1 number, col2 number, col3 number);
Table created
SQL> insert into xx_test values(1,2,3);
1 row inserted
SQL> insert into xx_test values(1,2,3);
1 row inserted
SQL> insert into xx_test values(4,5,6);
1 row inserted
SQL> insert into xx_test1 values(6,7,8);
1 row inserted
SQL> declare
2 cursor c is select col1, col2, col3 from xx_test;
3 type t is table of c%rowtype;
4 v t;
5 begin
6   open c;
7 loop
8 fetch c bulk collect into v limit 1000;
9   forall i in 1..v.count
10   update xx_test1
11 set col1 = v(i).col2;
12
13 insert into xx_test1(col1,col2,col3) values(v(i).col1,v(i).col2,v(i).col3);
14
15 exit when c%notfound;

Thanks in advance,

Stew, a bulk bind from an OCI client looks as follows:
OCIStmtPrepare()
OCIBindByName()/OCIBindByPos() (binding a host array)
while some-condition loop
fill host array
OCIStmtExecute() (specify the number of elements in array via the iters param)
end loopThe statement is executed once for each array element - according to the OCI guide. So in the case of sending a 100 elements, the statement will be executed (iterated) by Oracle, a 100 times. It however is not exactly clear on how the server-side deals with this execution.
The issue you raised with cursor execution counts, seems to be whether the statement is single statement, or single statement with nested statements.
I have written an OCI client doing the exact same tests as were done in PL/SQL using FORALL in this thread.
If the SQL statement executed is SQL, the cursor that is created is executed only "once" (not exactly true as multiple rows are inserted using a single row DML).
If the statement is PL/SQL, the cursor that is created, is executed "once". So pretty much the same behaviour. However, as this statement contains "nested" SQLs (the actual DML statements), these also need to be parsed and executed as cursors. In which case you see these as being executed a 100 times (once per element in for the bind array).
The issue is whether or not the FORALL DML statement is executed once (as it would appear from the executions column), or not?
It would seem that there is some funky happening (some kind of call optimisation perhaps?) when Oracle deals with an array bind - as the cursor seems to be executed once. But that in fact is not the case as that cursor only inserts a single row. And multiple rows are inserted.
E.g. simplistic example to see how many times the FORALL DML statement is executed:
SQL> create sequence emp_id_seq
2          start with 1
3          increment by 1
4          nocycle
5          nomaxvalue;
Sequence created.
SQL> --// add a PL/SQL user function wrapper for the sequence
SQL> create or replace function GetNextEmpID return number is
2          id      number;
3 begin
4          select emp_id_seq.NextVal into id from dual; --// explicit SQL statement
5          return( id );
6 end;

So there do seem to be some kind of optimisation on the Oracle side - however, it does not mean that the FORALL statement is not using bulk/array binding. It is. And that is what the FORALL statement is designed to do.

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)

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.

Oracle 8i array DML operations with LOB objects

Hi all,
I have a question about Oracle 8i array DML operations with LOB objects, both CLOB and BLOB. With the following statement in mind:
INSERT INTO TABLEX (COL1, COL2) VALUES (:1, :2)
where COL1 is a NUMBER and COL2 is a BLOB, I want to use OCIs array DML functionality to insert multiple records with a single statement execution. I have allocated an array of LOB locators, initialized them with OCIDescriptorAlloc(), and bound them to COL2 where mode is set to OCI_DATA_AT_EXEC and dty (IN) is set to SQLT_BLOB. It is after this where I am getting confused.
To send the LOB data, I have tried using the user-defined callback method, registering the callback function via OCIBindDynamic(). I initialize icbfps arguments as I would if I were dealing with RAW/LONG RAW data. When execution passes from the callback function, I encounter a memory exception within an Oracle dll. Where dvoid **indpp equals 0 and the object is of type RAW/LONG RAW, the function works fine. Is this not a valid methodology for CLOB/BLOB objects?
Next, I tried performing piecewise INSERTs using OCIStmtGetPieceInfo() and OCIStmtSetPieceInfo(). When using this method, I use OCILobWrite() along with a user-defined callback designed for LOBs to send LOB data to the database. Here everything works fine until I exit the user-defined LOB write callback function where an OCI_INVALID_HANDLE error is encountered. I understand that both OCILobWrite() and OCIStmtExecute() return OCI_NEED_DATA. And it does seem to me that the two statements work separately rather than in conjunction with each other. So I rather doubt this is the proper methodology.
As you can see, the correct method has evaded me. I have looked through the OCI LOB samples, but have not found any code that helps answer my question. Oracles OCI documentation has not been of much help either. So if anyone could offer some insight I would greatly appreciate it.

Before 9i, you will have to first insert empty locators using EMPTY_CLOB() inlined in the SQL and using RETURNING clause to return the locator. Then use OCILobWrite to write to the locators in a streamed fashion.
From 9i, you can actually bind a long buffer to each lob position without first inserting an empty locator, retrieving it and then writing to it.

How to find last DML operation in oracle ADF

how to find last DML operation in oracle ADF
Please help me
Thanks
Damby

In the base EntityIml class, just override doDML() method as I said.
(see http://docs.oracle.com/cd/E16162_01/web.1112/e16182/appendix_mostcommon.htm
"Methods for Creating Your Own Layer of Framework Base Classes")
So, put a some flag in the session.
You should not call doDML() method in backing bean, it will be called by framework.
In the backing bean, you only have to get that information from the session, as follows:
String last_dml_op = (String)ADFContext.getCurrent().getSessionScope().get("last_dml_op");And voila...

How to write DML operation in a function

Hi
Its very urgent for me.
I am writing DML operation directly in a function and is being called from select statement, it is getting error as "DML Operations cannot be performed inside a query".
How to write a DML operation inside a function.
My objective is to call that function from select statement.
Please help me out.
Thankd

No no no. You're committing after each row! soany
other session running the same query will see the
changes you're making. Your session will equallysee
changes caused by running this query in those
sessions.Other session, yes, but current session will only see
the changes once it has completed the current
statement. Otherwise my "rn" column would not have
gone up sequentially in the above example. it would
have gone
1st row rn = 1 (all rows get updated by 1:-
2,3,4,5,6,7,8,9,10,11)
2nd row rn = 3 (all rows get update by 1:-
3,4,5,6,7,8,9,10,11,12)
3rd row rn = 5 (all rows get update by 1:-
4,5,6,7,8,9,10,11,12,13)
4th row rn = 7 (all rows get update by 1:-
5,6,7,8,9,10,11,12,13,14)
5th row rn = 9 (all rows get update by 1:-
6,7,8,9,10,11,12,13,14,15)
6th row rn = 11 (all rows get update by 1:-
7,8,9,10,11,12,13,14,15,16)
7th row rn = 13 (all rows get update by 1:-
8,9,10,11,12,13,14,15,16,17)
8th row rn = 15 (all rows get update by 1:-
9,10,11,12,13,14,15,16,17,18)
9th row rn = 17 (all rows get update by 1:-
10,11,12,13,14,15,16,17,18,19)
10th row rn = 19 (all rows get update by 1:-
11,12,13,14,15,16,17,18,19,20)
So the fact the commit happens each time the rows get
updated, isn't effecting the currently running select
statement.
No, actually you DO see the other session changes. This is because it is AUTONOMOUS transaction, and this a function.
Test by adding:
create or replace function incvals return number as
pragma autonomous_transaction;
v_val number;
begin
update t set rn = rn + 1;
select max(rn) into v_val from t;
dbms_lock.sleep(1); --add this line
commit;
return v_val;
end;
And test in two sessions.
You will NOT get sequential ascending.
>
Think about the effect of two parallel sessionsboth
running this query at the same time, and ask isthis
sensible?Gawd, no, of course not. Like I said, I'd never use
this sort of thing myself. I'm just wondering what
on earth the OP is trying to achieve.
:)Glad to hear it.

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.

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.

Hi,
Yeah, I know there is a time lapse (approx 3 hrs) between the DML operations on the table and the time when they are logged in the DB. We waited for around a day to get these value populated in the DBA_TAB_MODIFICATIONS. But we are still not able to see any values in this table.
I am not able to guess the reason behind this. Kindly help.
Shall I try executing the flush_db_monitoring info to get these values?refer Thread: user_tab_modifications only updated by gather_stats_job?

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

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.

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"

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.
