>> Hi, I want to copy same records [sic] TEN times. How I can do from query. <<
One the
many ways a row is not like a record is that a row has to have a key. The
goal of all databases is to remove redundancy. You want to create redundancy and destroy any possible key! WHY? You also do not know that a query cannot create new rows; that would require an INSERT INTO statement.
What are you trying to do?

Help with querying a 200 million record table

Hi ,
I need to query a 200 million record table which is partitioned by monthly activity.
But my problem is I need to see how many activities occured on one account in a time frame.
If there are 200 partitions, I need to go into all the partitions, get the activities of the account in the partition and at the end give the number of activities.
Fortunately, only activity is expected for an account in the partition which may be present or absent.
if this table had 100 records, i would use this..
select account_no, count(*)
from Acct_actvy
group by account_no;

Must stress that it is critical that you not write code (SQL or PL/SQL) that uses hardcoded partition names to find data.
That approach is very risk, prone to runtime errors, difficult to maintain and does not scale. It is not worth it.
From the developer's side, there should be total ignorance to the fact that a table is partitioned. A developer must treat a partition table no different than any other table.
To give you an idea.. this a copy-and-paste from a SQL*Plus session doing what you want to do. Against a partitioned table at least 3x bigger than yours. It covers about a 12 month period. There's a partition per day - and empty daily partitions for the next 2 years. The SQL aggregation is monthly. I selected a random network address to illustrate.

The reason for the performance is simple. A correctly designed and implemented partitioning scheme that caters for most of the queries against the table. Correctly designed and implemented indexes - especially local bitmap indexes. Without any hacks like partition names and the like...

Copy Condition record

Hi,

change customer code but that field is in Grey I m not able to change customer code for the same materials.

akshay

Hi
Just make previous record invalid
Just go to VK12 and give the validity date of today.
From                 01.12.2008
Valid to             31.12.9999 (21.07.2009)
So from today onwards this condition type will be invalid
Just create the new condition record in VK11 for your different customer.
Now just create new record sales org/ Customer/ Material
      1000 / 594944 /   M10
New condition record valid.

Hello Suhale,
On retrospection, I found the query in my above response STILL HAS ONE ISSUE. When we are making a left outer join on vbkdposnr = vbapposnr we are only fetching vbkdinco1 and vbkdinco2 values where item level entries exist in VBKD which match with vbkdposnr = vbapposnr.
Actually we should bring inco1 and inco2 from vbkd when a matching entry exists in vbkd where vbkdposnr = vbapposnr and if there is no entry matching vbkdposnr = vbapposnr, then we should fetch inc01 and inco2 from VBKD where posnr = '000000' (i.e., from header).
This is how SAP behaves when you open an item in VA03 and look at inco1 and inco2. They come from the item if an entry corresponding to that item exists in VBKD otherwise they come from VBKD header record (where vbkd~posnr = '000000')
We can't use VBKD in the joins and still be able to do the above. So we need to fetch inco1, inco2 from VBKD separately like below.

When we click on the copy botton record with same name should not be saved

Hi,
Copy button will copy the record with the same name and will save it.our requirement is when we click on the copy botton ,record with same name should not be saved
we are performing this task in custom object 12 and exposed Opportunity Name in the layout.
Records with same Opportunity Name should not save ..when we copy the record
Can we perform any field validation on Opportunity Name field?
Please help
please email me @ [email protected]
Thanks
Srinivas Merugu

Opportunities that are assoicated to the same account cannot have the same name. You cannot make this unique for your whole instance. The only way that you could do this would be to create a webservice application that checks this before you save the record.
What about defaulting the name each time this could make the record unique?

Query to get the records with same last name

Select query for every 1000 records

Hi all ,
Please help me in the issue . I am using select query Select * from table up to 1000 rows for acheving the records but i want this process to retrigger once the process of 1000 records is compleded again it needs to fetch the next 1000 records and process the same . I am changing the status of the processed records once it is processed . Can can one tell me how to retrigger the select query once the 1000 records are processes.
Thanks in advance,

Hi Eric,
After selecting the 1000 records, find the key value of the last record. Build up the range as GT. Again use the select query.
For example,
Select * into table lt_data from ztab
where key in r_key
up to 1000 rows.

Niyaz

I want to wirte the query to display the records like

Means If same item exists with different rates in same invoice they should display like above
How possible with SQL only
Thanks
Hassan

Hi all,
I am replying this for your information. I used analytical functions and create an in line view. the query gave me the required results. This would help a lot of you. And if there is an error in my query i also would like to correct that.
select a.invoice_id, a.titem_id,
sum(decode(a.seq_no,1,rate_charged,0)) rate1, sum(decode(a.seq_no,1,amount,0)) amount1,
sum(decode(a.seq_no,2,rate_charged,0)) rate2, sum(decode(a.seq_no,2,amount,0)) amount2,
sum(decode(a.seq_no,3,rate_charged,0)) rate3, sum(decode(a.seq_no,3,amount,0)) amount3 ,
sum(decode(a.seq_no,4,rate_charged,0)) rate4, sum(decode(a.seq_no,4,amount,0)) amount4,
sum(decode(a.seq_no,5,rate_charged,0)) rate5, sum(decode(a.seq_no,5,amount,0)) amount5
from (
select invoice_id, ii.titem_id,ii.rate_charged,amount,
row_number() over(partition by equse_gkey order by ii.trate_rate ) seq_no
from invoice_detail ii
where ii.invoice_id in (947753)
and ii.titem_id in (select Id from rates where tserv_id='BIS-20')) a

Help with query to do with aggregating for MIN(DATE)

Say i have the following table of data:
Table: TEST
ID     TDATE     CLIENT     VAL
1A     1/10/2005     client1     10
2A     2/10/2005     client1     30
3A     3/11/2005     client2     22
4A     5/10/2005     client2     43
5A     5/10/2005     client2     3
6A     6/10/2005     client3     5
7A     7/10/2005     client3     76
I want to create a query that will retrieve a distinct list of the CLIENT column (ie. in the above table I want only 3 records retrieved in the query as there are only 3 clients) and the corresponding ID and VAL for the client record with the MIN(DATE). In the case where 2 dates are the same, I dont care which record is selected as long as the ID and VAL columns belong to the same record.
For example in the above data I would expect the following returned in the query:
ID     CLIENT     VAL
1A     client1     10
4A     client2     43 <- this record could also be 5A, client2, 3
6A     client3     5
Please help.

Hi Joshua,
You didn't post your Oracle version but I hope it supports analytic functions.
Try as follows:

4         val
5    from (select t.*,

7                   (partition by client order by tdate) rn
8            from test t)
9   where rn = 1;
ID         TDATE      CLIENT                                VAL
1A         01/10/2005 client1                                10

Hi,
This query should be fine:

How to find out query for the deleted record.

Hi Guys,
We are using Oracle9i release 1. We are about 5 employees who are working on the same application. All Employee are connected to the same Schema (User)
User: Employee/web
Now one of the user have deleted like 200,000 records from a table. We just want to trace out the query by which these records were deleted.
From which file i can get the log of executed queries so that i can recover the data.
Just want to know the query executed for this deletion of records?
we are using windows server.
Regards,
Imran Baig

If you do not need an exact query, but only the way you can reconstruct the data, LogMiner can be solution for you. Below I have put a simple example you can review it if you want.
[email protected]> create table t201 as select object_id , object_name from all_objects where rownum < 10;
Table created.
[email protected]> select * from t201;

Return to same record on previous page after using form

Hi,
I have an application that contains a table with tasks and subtasks (which are linked to a task), and for every task, there is a 'add subtask' link, which links to a form where I can create new subtasks for that task.
My problem is that when I have created a new subtask, and return to the previous page (with the overview of tasks and their subtasks) automatically by clicking the 'create'-button, that the report starts again at line 1. I would like it to go back to the same task for which I just added a subtask.
In my search for the answer, I came across these two discussions on this forum:
Re: navigate to previous record
after edit, return to the table where the record is at the same position
I tried to implement the solution they came up with in those discussions, but it didn't work for me.
The reason of this might be:
- It are old discussions, maybe some things have changed
- I use a standard report with custom template, they do not
- My link is on a field that has the same value for all records, being just a text item 'Add subtask', in the other discussions they made the link on an actual DB-field, in my case this would be for example task_id.
When I try to implement the solution on the second forum exactly (well, not exactly, I did of course adapt this to my situation), there is one step which doesn't work for me. It's the very last step:
"With these values: #LINK_&P2_EMPNO."
When I put the # in there, the button deletes all the information about the link when I click 'Apply changes'. When I don't use the # (just LINK_&P2_EMPNO.) he doesn't delete the information, but the link to the same record doesn't work.
This is how I implemented it:
Source page (overview of tasks and subtasks):
Link attributes: LINK_#TASK_ID#
Target: Page in this application Page: 4 (form)
Item 1: Name: P4_TASK_ID, Value: #TASK_ID#
Item 2 (not important for returning to the source page): Name: P4_YEAR, Value: #YEAR#
Item 3 (not important for returning to the source page): Name: P4_TEAM, Value: #TEAM#
Target (form):
Action when button clicked: Redirect to page in this application
Page: 3 (source page)
With these values: LINK_&P4_TASK_ID.
It doesn't return to the correct record, but the task_id is included in the link as follows (when I tried to create a new subtask for task 02.01.08 and returned to the source page) f?p=37080:3:5503066190863::NO:::LINK_02.01.08 which is almost the same as they say in the discussion: f?p=&APP_ID.:1:&SESSION.::&DEBUG.:2::#LINK_&P2_EMPNO. (missing the '#'-sign and 1 less ':' before the link-item though).
Why isn't it working for me? How can I solve the problem?
Could I get some help with this please? It would be a very useful functionality in my application as there are a lot of records.
Thank you.
Kind regards,
NDG

Suggestion for not picking up the same record

Hi All,
I have a plsql procedure that picks up the records from the same table from multiple threads. Different threads should not pick up the same record.
Current Logic:
I am locking the row that has been picked up the current thread and the next thread should pick up the next row but unfortunately i have a problem here, The inner query will pick up the same record until the status of that particular row is changed since I am picking them up in a FIFO order.
I am not able to add the lock row in the inner query since oracle does not support it. Is there any other way to do it simpler?
XXRM_ARM_HEADER
header_id
service_id
XXRM_ARM_LINES
line_id
header_id
status
Query
SELECT dl.header_id, dl.line_id
FROM xxrm_arm_header dh, xxrm_arm_lines dl
WHERE dh.header_id = dl.header_id
AND dh.service_id = 4
AND dl.status = 'REQUEST_RECEIVED'
AND dl.line_id = (SELECT LINE_ID
FROM ( SELECT dl.line_id
FROM xxrm_arm_lines dl,
xxrm_arm_header dh
WHERE dh.header_id = dl.header_id
AND dl.status = 'REQUEST_RECEIVED'
AND dh.service_id = 4
ORDER BY dl.line_id ASC)
WHERE ROWNUM = 1)
FOR UPDATE OF dl.status NOWAIT SKIP LOCKED

forgive me if I am naive, but why wouldn't each thread updating its selected rows with a nowait and if exception pick the next range mechanism work?It is not that simple. You can get race conditions between threads as they process the same rows in the same order attempting to "beat" one another by being the first to lock it. The more threads there are, the potentially worse this situation.
There's also the issue of performance. The thread concept (aka parallel processing) in this respect has a single primary aim. Increase performance and scalability. But does it?
How is I/O reduced when 50% or more of the reads done by the thread (to find a row to process) is wasted I/O as rows being read have already been locked by other processes/threads?
The fact remains that if you give the same set of rows to a bunch of threads (e.g. DBMS_JOB processes) for processing, they will contend for the same rows. There will be overheads. There will be wasted I/O.
So what I am suggesting is each thread; -
1. Look for rows unprocessed, I usually use atribute field in e-Business suite for this purpose
2. Attempt to update them with nowait, to INPROCESS
3. If 2 fails, try the next range - repeat until 2 is possible or end of rangeAnd step 3 is the one that will waste I/O and waste time - as the time it spend looking for a row to process could have been spend on actually processing a row.
4. You could also improve this by specialising each thread to have its own preferences, if there exists a mechanism that would mean fair distribution between the threads..Yes, and this is a key factor to removing contention between threads, reducing their I/O overheads and reducing their time being spend on finding unprocessed rows to lock and process.
Then there's Oracle technical issues. On 11gr2 for example, despite using skip locked or nowait (that cannot be used together in a single clause like in 10g), I'm seeing deadlocks when threads contend for the same rows. Same code works fine in 10g without deadlocks. So the approach one chooses need careful testing on that specific Oracle version to ensure it behaves as expected and meets the performance requirements.
Bottom line is that parallel processing is not as straight forward as simply slapping a nowait clause onto a select statement in order to skip locked rows.
