For Update Query

Hi All,
I having block level 8000 records, I Scroll down from First record to last record it is takeing more time.
I Observed tkproof while scrolling two select statments are running..
1) pre-query block level
2) For update query
For update query -> How is is forming? Any Property or some else?
I am not able to find the second query..where it is forming..How to restrict the second query.
Query Array size - 10
Number of records buffered - 10
Number of records Displayed - 10
Query all records - No
Locking mode - Immediate
Key mode - Automatic
Version - Oracle 10g
Plz ........any

The for update -query is generaetd by forms when its locking the record. If you didn't change anything in the record "by hand", check if there is some code in the POST-QUERY-trigger which forces the record to be locked. if its the POST-QUERY you can issue the following command to avoid the lock at the end of the POST-QUERY:
SET_RECORD_PROPERTY(:SYSTEM.TRIGGER_BLOCK, :SYSTEM.TRIGGER_RECORD, STATUS, QUERY_STATUS);

For Update Query with Wait Clause from ORACLE Forms

Hi
We are using Oracle Forms 10g running with 10g database 10.2.0.1.0. We happend to see a query which is getting generated in AWR report like Select rowid, all_columns from TableName for Update of C1 Nowait. But no such query is really written in forms and we are aware that, Any query prefixed with rowid is definitely executing from Forms. But how the ForUpdate and Nowait clause is appended to the query.
We have checked the following properties in the database Block
*1) Locking Mode is set to Automatic*
*2) Update Changed Columns only is set to YES*
*3) Query all records is set to No (Though this particular property may not be relevant to the issue)*
What is the property or setting which might trigger such a query from ORACLE Forms with ForUpdate and Nowait clause.
Any ideas/suggestions on why such behaviour. Please have a healthy discussion on this. Thanks in advance.

Why have you started another thread on the same thing?
FOR UPDATE cursor is causing Blocking/ Dead Locking issues
Just use one thread to avoid confusion.
The fact that nobody has answered on the other thread for a couple of days could be to do with it being the weekend and most people are not at work.
Either be patient or, if it's more "urgent" than that, raise a SR/Tar with Oracle metalink.

FOR UPDATE query issue

SELECT table_name FROM all_tables WHERE dropped = 'NO' and owner = 'test'
FOR UPDATE;
ERROR at line 1:
ORA-02030: can only select from fixed tables/views
ORA-06512: at line 9
ORA-06512: at line 16
Can any body help me out what is wrong in that query.
Thanx

SELECT table_name FROM all_tables WHERE dropped = 'NO' and owner = 'test'
FOR UPDATE;What do you want to achieve from this?? Do you want to update the all_tables ?? :-)

you can't dynamically add a query to the data model in reports.
You should look into the XML based customization of Oracle Reports. This will enable you to define a report dynamically by creating a definition in XML.
Also another option is to have the report with a query in it and use lexical parameters in reports to pass the query definition or just the where part of it.
Look at the reports online help for both of these solutions.

Select for update query not working..

hi i am tying to get this bit of ncode to work so i can then go to the next part of demonstrating a deadlock between two transactions. however i cannot go any further has my initial code does not work at all. here it goes
//////////User A////////////////////////////////
DECLARE
v_salary squad.salary%TYPE := 300;
v_pos squad.position%TYPE := 'Forward';
BEGIN
UPDATE squad
SET salary = salary + v_salary
WHERE sname = 'Henry';
FOR UPDATE;
UPDATE squad
SET position = v_pos
WHERE sname = 'Fabregas';
COMMIT;
END;
//////////////////////User B/////////////
DECLARE
v_salary squad.salary%TYPE := 200;
v_pos squad.position%TYPE := 'Forward';
BEGIN
UPDATE squad
SET position = v_pos
WHERE sname = 'Fabregas';
FOR UPDATE;
UPDATE squad
SET salary = salary + v_salary
WHERE sname = 'Henry';
FOR UPDATE;
COMMIT;
END;
Basicly user a creats a lock and so does user b, user b enquires a lock from user a and vice versa i.e. a deadlock

Hi
You get the following error:
ORA-06550: line 8, column 7:
PLS-00103: Encountered the symbol "UPDATE" when expecting one of the following:
because the FOR UPDATE; is invalid in your statement.
Try this:
//////////User A////////////////////////////////
DECLARE
v_salary squad.salary%TYPE := 300;
v_pos squad.position%TYPE := 'Forward';
v_n number;
BEGIN
UPDATE squad
SET salary = salary + v_salary
WHERE sname = 'Henry';
select 1 into v_n from squad
WHERE sname = 'Fabregas'
for update;
UPDATE squad
SET position = v_pos
WHERE sname = 'Fabregas';
COMMIT;
END;
//////////////////////User B/////////////
DECLARE
v_salary squad.salary%TYPE := 200;
v_pos squad.position%TYPE := 'Forward';
v_n number;
BEGIN
UPDATE squad
SET position = v_pos
WHERE sname = 'Fabregas';
select 1 into v_n from squad
WHERE sname = 'Henry'
for update;
UPDATE squad
SET salary = salary + v_salary
WHERE sname = 'Henry';
COMMIT;
END;
To syncronize the blocks first in a SQLPlus call these two statements:
select 1 from squad WHERE sname = 'Fabregas' for update;
select 1 from squad WHERE sname = 'Henry' for update;
After this start the user A code in another SQLPlus, and start the user B code. After this call rollback or commit in the first sqlplus.

Syntax for Update Query?

Hi
I have the following query:
update martin_adhoc_pct
set adhoc.mbr_oed = mbr.orig_eff_date
where adhoc.subs_ssn = mbr.subs_ssn
and adhoc.mbr_type = mbr.mbr_type
I get an error saying that:
ORA-000904 "mbr"."mbr_type" invalid identifier..
I am using PL/SQL and pulled the table name and field directly from the Objects listing so the names are right. This is the first time I've attempted an UPDATE statement with SQL, so wondering what I'm doing wrong..
Thanks for any help..

Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production
I have created a table in our data warehouse that has a blank column (specified as datatype DATE) that I want to update with data from another data warehouse table (one that I didn't create). So for example:
ssn mbr type oed
123456789 aab needs to be filled in
987654321 dd1 needs to be filled in
etc..
The unique identifier is the sub id and mbr type, so that's why my code joined these fields between the tables. Where they are equal, fill in the associated oed. I need all rows filled in, not just one. Here is the created table code:
SELECT mbr00.mbr_type,
        mbr00.mbr00_subs_ssn,
        me607.subscriber_id,
        cast (null as date) mbr_oed
from odw.member_exp me607,
        odw.member_mas mbr00
where   me607.subscriber_id = mbr00.mbr00_ssn_ref_num
and     me607.elig_start_date < sysdate
and     me607.elig_end_date > sysdate
and     me607.rmc_code in ('123')
{code}
Thanks..

Better method for update query

Thanks in advance for any help you can offer on this...
I have two tables:
DETAIL_TABLE with columns: email_address, invalid_format_indicator, source, create_date
SUMM_TABLE with columns: run_date, source, email_address_cnt, invalid_email_address_cnt
Each week I run a job that truncates, then inserts new rows into the DETAIL_TABLE of email addresses that are likely invalid (invalid_format_indicator = 'Y'), and the source system ("source") that created them, as well as the date they were created in our system. Later in the process of that same job, I add new rows into SUMM_TABLE with counts.
So, for data:
DETAIL_TABLE:
email_address|invalid_format_indicator|source|create_date
joe.aol.com|Y|web|2011-03-01
mary@myurl|Y|web|2011-03-05
larry 2yahoo.com|Y|phone|2011-03-06
After the DETAIL_TABLE is refreshed, new rows (14 of them) are inserted into the SUMM_TABLE whereby it creates a new row for each source. What I then want to do is update the 'invalid_email_address_cnt' field by counting the number of rows in DETAIL_TABLE, grouping by source.
Right now, I'm running 14 update queries simultaneously--one for each source.
Data looks like this after the update is complete (bear in mind, it's being updated via 14 separate queries):
SUMM_TABLE
run_date|source|email_address_cnt|invalid_email_address_cnt
2011-03-06|web|25|5
2011-03-06|phone|3|1
2011-03-06|loader|20|4
2011-03-06|source14|5|2
It looks like this BEFORE the update:
run_date|source|email_address_cnt|invalid_email_address_cnt
2011-03-06|web||
2011-03-06|phone||
2011-03-06|loader||
2011-03-06|source14||
I'm currently running this update statement:
Update SUMM_TABLE S
set invalid_email_address_cnt =
(Select count(*)
from DETAIL_TABLE D
where D.source = 'web'
and D.invalid_format_indicator = 'Y')
where S.run_date = sysdate
and S.source = 'web';
I repeat this query 13 more times-- one for each source. Ick...
I'd like to consolidate it to one query. I prefer not using PL/SQL. The tool I'm using doesn't support PL/SQL (It's an open source ETL tool), so if I can do this via straight SQL (Oracle compliant) that would be ideal.
Any help would be greatly appreciated!

I believe you just want a correlated update
Update SUMM_TABLE S
   set invalid_email_address_cnt =
      (Select count(*)
        from DETAIL_TABLE D
       where D.source = s.source
         and D.invalid_format_indicator = 'Y')
where S.run_date = sysdate;I'm not sure, though, about the WHERE clause. Surely you mean TRUNC(sysdate) or you're using a local variable that you used to insert the row into the summary table. Otherwise, if you get unlucky and the clock ticks while your procedure is running, the update may not affect any rows.

Problem for running Update query with Chinese

Hi all,
I am running a web application in Lotus Domino.
I have a Lotus Script Agent which need to update Oracle 8i Database with Chinese Character throught ODBC but i find that all characters become some strange characters.
I got the problem only for update query.
I have no problem for select query for getting the chinese data.
Also, I got no problem to run the update query with chinese characters in Sqlplus.
I also try to run the same update query which the ODBC connection is pointing to an MS Access Database. It works too.
So the only things i leave is the Oracle ODBC driver.
Anythings I should do for the Oracle ODBC server?
Thanks very much.

Hi, I checked the registry of Oracle and
in the NLS_LANG field, the values is AMERICAN_AMERICA.UTF8. In the server side, I set the same.
It should be okay, as i can retrieve the chinese content in the Oracle. Just that when i try to run a query contain chinese, such as,
"insert into TableA values ('��')". i will got some strange character inserted in the databasae.
Could you tell me what should i do?
Thanks a lot a lot.

Hi Chinna,
Check like this below.
The following SQL statement selects the product name, and price for today from the "Products" table:
SELECT ProductName, Price, Now() AS PerDate
FROM Products;
Similarly,
UPDATE ProductName, Price, Now() AS PerDate
FROM Products;

Update query in jdo

I am looking for update query in KODO 4.0. How can I use named query to update "all Companies with number fo employers less then 10" ?
I seen kodo.query.Query::updateAll method but not able to get an instance of it, because it seems to be reserved for jpa interfaces only...
any idea ?

Hi have found the way to issue update query:
String queryString =
               "update buying.changetrackingexportentry " +
               " set id_confirmedstate = " + state.getId() +
               " where id_confirmedstate = " + state.getId()
               +
               " and id_changeexportregistration in" +
               " (select id from buying.changeexportregistration where id_externalprocess=" + exportId + ")"
Query query = (Query)getJdoTemplate().execute(new QueryCallback(queryString));
((kodo.jdo.QueryImpl)query).updatePersistentAll(params);

Select for update timing out

Hi there
when I do a simple select statement like
select * from table
I recieve all the records without a problem
when I add 'for update' like
select * from table for update
this seems to take a long time (I don't actually get a result)
Is there something I'm doing wrong or have I incorrectly set up my oracle server?

As you are saying that your normal query is running fine but if you are using query with for update of it takes more time than previous.
But it is normal behaviour of the oracle itself, when you use for update of, oracle put lock on selected row and then dont allow other users to access it unless and untill first user finish the desired task on selected row. It creates delay in response of your for update query.

Unlock SELECT FOR UPDATE

I have to do a "SELECT FOR UPDATE" query to modify a CLOB column.
The problem is that i want to release this lock BEFORE i commit or rollback de transaction.
How can i do it?
Thanks

Also, i want to release the lock to prevent a deadlock with another transaction, but without doing a commit, so i can rollback it if any error is produced after. You must remember that releasing the lock means that you are not interested in that part of the transaction (or the entire transaction). You cannot have the option of releasing the lock and preserving the transaction so as to allow others to do whatever with that data. This will violate transaction integrity.
Partial rollback seems to be what you need. If the driver is the problem, you could always package your logic into a procedure (prefarably in a package) and call that procedure from your driver (hoping the driver allows calling of stored procedures).

Performance of update query for single column vs multiple column

Hi All,
I could not find any answer for this, does it ever matter in terms of performance updating single column versus multiple column in a single update query.
For eg. table consisting of 15 columns, what would be the difference in performance when one column is update in the single query against another update query where 15 columns are updated.
Please do keep in mind my table columns in actually could be around 150+.
Thanks for any information provided.

If updated columns aren´t on where clause , then the only impact of 15 columns will be a increase on redo generation, and a possible chainning row.
So since the redo is one of the things that have a large impact, the answer is yes.
The performance will be slower.
