SQL & PL/SQL :: Possible To Commit Changes In Certain Rows Of Certain Tables
Jun 29, 2011
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.
I have the task that I have to determine the number of parts that need to be produced based on the number of products sold for the day (each product consists of many parts).
I am using SQL 11g Express.
The report would look something like this:
{OrderDate PartID PartDesc NumOfParts(Total for that day) 10-24-2011 2001 12" X 12" Solid Shelf 108 10-24-2011 2003 12" X 24" Solid Shelf 32 10-24-2011 3001 96" Side Panel 50
[code].......
My issue is, I can't get the equation right to produce the total number of parts. I think I need to multiply ProductPart.NumOfParts by SUM(CustOrder.Qty) Group by CustOrder.SKU.
Below I have what the calculations should look like
i work on oracle 8i with around 950 tables in my database. when i export or import it gives me the no of rows exported / imported from each table. is it possible to take a print out of the no of rows in each table through a single query .
select count(*) from each table takes a long time , since there are 950 tables.
We have two tables, TableA and TableB that contain list of accounts and balances.The requirement is to compare the balances of accounts in both the tables, and if there is a difference, then record that difference with account number in another table.
Both TableA and TableB contain more than 10 million rows.What is the best way to do this task in PL/SQL? A join on TableA and TableB to know the differences has become very slow due to large volume.
Here the SUB1 and SUB2 are "tables" and are similar in their structure. The "Main_Table" will be update dynamically and the no of rows in this table will vary.
Now my question , i need to create a view which will have all the rows from these tables ,in the current case it is something like
create or replace view sample as select * from SUB1 union all select * from SUB2
How can this be achived. I tried as shown below:
spool file_to_exe.sql select 'select * from ' || AA ||' union all ' from Main_table; spool off
i will end up in a union all "extra" , if i do like this.
DECLARE L_DE_TGUP_ID BBP_ALLOC.DATA_ELEMENT.DATA_ELEMENT_ID%TYPE; L_ZERO_EXP EXCEPTION; L_DATA NUMBER; BEGIN SELECT DATA_ELEMENT_ID INTO L_DE_TGUP_ID FROM BBP_ALLOC.DATA_ELEMENT WHERE DATA_ELEMENT_CD = 'TGUP'; SELECT DECODE(UPPER('0.0028'),'',0,'0',0,'NULL',0) INTO L_DATA FROM DUAL; [code]......
Here the relationship between the source and target tables is one to one. but still i am getting "unable to get the stable set of rows from the source tables" error. Source query retrieves only 2 rows which are distinct. but still getting this error.
A block shouldn't have rows from multiple tables... Is that true? I read in one of the OTN thread (i don't exactly remember the thread name) that a block can have data from multiple tables. If it doesn't have, what's the table directory in block signifies?
create a procedure or cursor to allocate extents to all tables with zero rows for all the user in the database.I have used the below query to check table with zero rows and no extents allocated.
select onwer,table_name,initial_extent from dba_tables where initial_extent is null order by owner; I generated the query to allocate extents by using concatenation in the above query. select 'ALTER TABLE '||table_name|| ' ALLOCATE EXTENT; ' from dba_tables where initial_extent is null order by owner;
now I want the extent allocation for such table auutomatically for aal the tables with zero rows.
I am trying to insert rows in two tables using sql loader.
I have two tables in database as
SQL> desc name Name Null? Type ---------------------- -------- ------------ ID NUMBER NAME VARCHAR2(20) BD DATE
SQL> desc name3 Name Null? Type --------------------- ----------- ------------- ID NUMBER NAME VARCHAR2(20) BD DATE
I created controlfiles as
[oracle@DBTEST sqldri]$ cat datafile.ctl options (direct=true) load data INFILE * into table name truncate when id='1'
[code]....
when i run sql loader as
[oracle@DBTEST sqldri]$ sqlldr hr/hr control=/u01/sqldri/datafile.ctl SQL*Loader: Release 10.2.0.1.0 - Production on Tue Aug 7 23:30:07 2012 Copyright (c) 1982, 2005, Oracle. All rights reserved. Load completed - logical record count 2.
no rows is inserted..the log file contain entries as
[oracle@DBTEST sqldri]$ cat datafile.log SQL*Loader: Release 10.2.0.1.0 - Production on Tue Aug 7 23:30:07 2012 Copyright (c) 1982, 2005, Oracle. All rights reserved. Control File: /u01/sqldri/datafile.ctl Data File: /u01/sqldri/datafile.ctl Bad File: /u01/sqldri/datafile.bad
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.
Tell 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.
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.
I 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 [code].........
