How can we commit for every 500 rows in pl/sql block.
begin
for i in 1 to 10000
loop
Insert into t1 values(i);
commit;
end loop;
end;
Here I am commiting after all the rows are inserted ,but i want to commit for every 500 rows are inserted .
I am using the SQL-Developer to access and manipulate a database. I am not very sure about the format of the database (I'm new to databases), but I had to setup the TNS-folder.
Anyway, I guess the problem is the same for any database.
I am having a table with the BOM (bill of material) positions of certain articles and I want to change the BOM quantities of some of the articles. What happens is that I can only change some of the rows. For other rows I get the message like (it is in German, so I try to translate it):
"data was commited in another/the same session already. row cannot be updated"
This error message looks like there is somebody else locked on the database and manipulating it, correct? Is that possible to see somewhere which processes/people are currently accessing to the database?
I saw that there is one process/another database, which is having the authorization to access to the database. But where can I check if this process is accessing to the database?
BTW: I used to do this process before, and it worked. I had been able to manipulate arbitrary entries on the database. I guess that the process or the person, mentioned above, hasn't been accessing to the database at that time.
I need to load 2 trillion data from an external table to Oracle Heap table. I am using Direct Path insert for that. how to commit after inserting n number of rows.

How to rollback after commit.
View 5 Replies View RelatedI have this stored procedure and sequences:
create sequence a_seq;
create sequence b_seq maxvalue 26 cycle;
create sequence c_seq maxvalue 1000 cycle;
create or replace
procedure inserta_en_B (numregistros in integer) as
ultimo_año_nuevo date := trunc (sysdate,'year');
dias_transcurridos number(3) := sysdate - ultimo_año_nuevo;
begin
[code]........
First i insert into b 400000 rows using:
execute inserta_en_b(400000));
commit;
But then i need to insert 100000 rows more using the stored procedure and without removing the 400000 rows stored before. I think i need to use the commit clause, but i dont know where.
Can we use commit in a function?
View 10 Replies View RelatedTell me restriction on commit means where this keyword is not used....like i somewhere read in trigger we can't used commit...instead of that we use pragma autonomous_transaction..
but my confusion arise when i see commit used in trigger in our database table....
is commit used in trigger , if not then what will be use...
Another one is commit used while creating procedure or function?
I have written a purge package that would delete records older than 10 years. Since the data is huge, the purging was taking 14 hours plus. To improve performance, I disabled constraints , deleted records and then reanabled them. This was quite quick but the only problem is rollback. Say for some reason if enabling constraints fails there is no way to rollback as enabling and disabling constraints does an implicit rollback.
View 1 Replies View RelatedI am using commit in a trigger as given :
create or replace
trigger comt after insert on tbl_city
declare
pragma autonomous_transaction;
begin
commit;
dbms_output.put_line('Value is committed');
end;
Now when I perform an insert in tbl_city---->trigger fires properly and gives output stream. But If I perform rollback now --->there are the data rollbacked in table.
why?I think after commit(which is in trigger associated at insert to table)there should no any rollback in table.
I have made a correlated update statement using rowid. Find my attachment. Its updating all columns which i wanted but issue is that its not updating in 1st commit.
Suppose 6 rows is to be updated, then in 1st commit its updating 1 record, then in 2nd commit its updating 2nd record and so on. And in Toad its showing 6 rows updated in 1st commit, then 5 rows updated in 2nd commit and 1 rows updated in last record. I want that all records to be updated in first commit only.
why commit is not allowed in trigger?
View 3 Replies View RelatedI am calling a child form from a parent form.It works perfectly if the parent form is adding records and while entering records when i press the button to call the child form, the whole things work perfectly according to plan.
The problem begins when i run execute query command in the parent form and then call child form then it does not "commit_form". So this is my problem that child form does not work perfectly when parent form is being called in execute_query procedure.
My working:
1) I read in the documentation that When parent form status is query_only then child will also have the same mode regardless of the parameter given in call_form.So i checked the :SYSTEM.FORM_STATUS of both the parents and child form,it shows "CHANGED" hence this point is covered. (dont know how come the parent form is in changed status but at least it is doing my work)
2) I further read and found that Commit_form procedure make the :SYSTEM.FORM_STATUS as QUERY. Here i am facing problem as in child form when i make changes and press commit form. Then before commit_form and after commit_form the :SYSTEM.FORM_STATUS results in "CHANGED".You can see this in the following code which i have written in save button.
message(:SYSTEM.CURRENT_FORM || ' a ' ||:SYSTEM.FORM_STATUS); pause;
commit_form;
message(:SYSTEM.CURRENT_FORM || ' b ' ||:SYSTEM.FORM_STATUS); pause;
IF Form_Success THEN
Commit;
IF :System.Form_Status <> 'QUERY' THEN
Message('Error prevented Commit');
RAISE Form_Trigger_Failure;
END IF;
else
message('FAIL');
END IF;
exit_form;
then at last exit_form module shows that" i have unsaved data in the form" save Yes-No-Cancel?
I hv a situation where a webservice interacts with the database.
Here the webservice will first make a request to database for some operation but i dont want the database to commit changes in first request itself. A response will be sent to webservice further a second request will be sent to database for committing the changes. So can that be done?
What would be the best way to Commit after every 10 000 records inserted from one table to the other using the following script :
DECLARE
l_max_repa_id x_received_p.repa_id%TYPE;
l_max_rept_id x_received_p_trans.rept_id%TYPE;
BEGIN
SELECT MAX (repa_id)
INTO l_max_repa_id

After committing form i want to clear few item and retain few item and make the form ready for next record to be inserted along with retained item.
View 4 Replies View RelatedI have a problem with key-commit trigger. I have written some validations and computations criteria on the block level (lines level). Actually there are a number of loops involved in it.
Problem is that the computations are performed twice. (may be the validations would also be performed twice, which couldn't be felt ). Since i read somewhere that key-commit is fired on different events, which i infered to be firing only just before database commit.
I need to insert almost million rows in my database.I have already split the row in separate files so that task would be easier. Now, i am planning to put commit after every 1000 line so that undo generation would be less and no locking would take place if i inserting those lines from multiple sessions.
But how can i insert commit after every 1000 line??
I searched, found this one hit and according to mateoc15, you cannot commit within a procedure that is called from a trigger. He must be right, because mine is not committing either, nor are any errors given.
Trigger
Create or replace trigger owner_name.table1_trg2
after update on table1
for each row
call owner_name.procedure1;
procedure Code (psuedo):
Create or replace procedure1 as
begin
update table1 set col1 = 'whatever';
commit;
exception when others then
rollback;
Executing the procedure as owner_name on SQLPlus works fine, but when I update a column of the table via the PL/SQL package (on the web form), the column does not update, telling me that the procedure never fired from the trigger.
Query in format Query@DB_Link is sometimes dropping transactions. Move it to a package on target dababase "B" called from DATABASE "A" via package.procedure(varaibles);
Is that all I need to do to get the transaction to always go? I tried a commit in the package body, with repeated attempts if it fails. Btu when I use commit, the package doesn't work. (Compiles fine) Why would the commit fail?
My goal is to make that the transaction succeeds.Code for what I tried below. the COMMIT is commented out - if I uncomment it, the transaction fails. I have done this before calling an oracle SP from SQLServer and it worked
Comments:
The loop is to avoid an endless cycle..The concept is to perform the update, commit it, if the commit fails, rollback and try again.I'm not sure if I even need a loop, but I don't know if the unresolved transaction would get fixed by the remote DB, or dropped.

If in a PlSQL procedures there are many DML statements which are part of the same transaction. and there are many calls to other PLSQL blocks also.
what is the best practice to use commit either after each DML statement or to use it in the End of Block?
I am working with an oracle table that is populated by a trigger on another table.. So Table A is an audit of table B. The trigger also uses sysdate to populate a modification Date column on the Audit table.
I was using this modification Date column in a query interface to get changes that happened on the main table after a certain date/time.
The problem is that there is an application that uses transactions to write to table B and sometime this transaction may not be committed for over a minute so the modification Date is not a reliable way to query the table for changes after a certain time.
Is there a way to update the trigger/create a new one where the sysdate that gets written to the audit table is from when the transaction is committed, not when the transaction starts?
Is it possible to clear the form after a successful commit? In order to avoid the user from double posting of record by making double commit.

while i'm inserting a records into the table tablespace has got full and next statement which is commit is executed
so now i need to remove the data due to the last insert into the table.
Table size is very huge and i was unable to find the records any criteria.
i made this loop to commit the same item but depend on the count of suppliers to set the same item every time to different supplier . but the problem this code commit only the first sypplier but not any othere one ..
code : { key - commit - trigger }
declare
var_record_count number ;
VAR_p_request number;

We all know that commit will do the following.
1. Save the Txn Permanently to the database.
2. Release the table locks and
3. Erase the save points.
TABLE NAME:
==========
create table TEST_PREC (NO NUMBER(4,2));
DECLARE
BEGIN
INSERT INTO TEST_PREC VALUES (12.34);
DBMS_OUTPUT.PUT_LINE('the no of records before commit '||SQL%ROWCOUNT);
commit; /* What's happening inside commit */
[code]....
why the SQL%ROWCOUNT is set to zero after commit.
Does the commit, close the implicit cursor?
