How to update a table that has Million Records
Hi,
Lets consider the basic EMP table and lets assume that it has around 20 Million Records . we need to have an update statement.Normal UPdate statement may hang the system or it may take a lot of time.
The basic or Normal update statement goes like this and hope it may not work.
update emp set hiredate = sysdate where comm is null and hiredate is null;Basic statement may not work. sugestions Needed.

I heard Bulk collect will resolve these type of issues and i am really poor at Bulk Collect concepts.Exactly what type of issue are you concerned with? The business requirements here are pretty important-- what problem is the UPDATE causing, specifically, that you are trying to work around.
so looking for a solution to the problem using Bulk Collect .Without knowing the problem, it's very tough to suggest a solution. If you process data in batches using BULK COLLECT, your UPDATE statement will take longer to run and will consume more resources on the database. If the problem you are trying to solve is that your UPDATE is not fast enough, this is a poor approach.
On the other hand, if you process data in batches, and do interim commits, you can probably hold locks on individual rows for a shorter amount of time. That would only be a concern, though, if you have some other process that is trying to update the same rows that you are updating at the same time that you're updating them, which is pretty rare. And breaking your update into multiple transactions introduces a whole bunch of complexity. You now have to write a bunch of code to ensure that your process is restartable should the update fail mid-way through leaving some number of updates committed and some number rolled back. You have to have a very detailed understanding of the data and data consistency to ensure that breaking up the transaction isn't going to negatively impact any process, report, etc. To do it correctly is a pile of work and then it's something that is constantly at risk of creating problems in the future when requirements change.
In the vast majority of cases, you're better off issuing a simple SQL statement during a time when the system isn't particularly busy.

How to update a table that has around 1 Million Records
Hi,
Lets take the basic emp table for our Referenece and lets assume that it contains around 60000 Records and all the deptno in that table are Initially 10. Please provide an update statement which would update deptno column of EMP table((based on) order by EMPNO) in for every 120 records incrementing by 1.(DeptNo to be incremented by 1,like 10 ,11 , 12 etc).
First 120 Records deptno should be 10,
Next 120 Records deptno should be 11, and so on.
For Last 120 records deptno should be updated with 500.
Please advise.
Regards,Ok, I've done it on a smaller set, incrementing every 5 records...

How to update a table that has hundred thousand rows?
Hi all !
I detect that I did wrong with column SHAPE (in GRAG table ) ,namely at Gtype : 3003
(MDSYS.SDO_GEOMETRY(3003,50632625,'null',MDSYS.SDO_ELEM_INFO_ARRAY(1,5,1,1,2,1),MDSYS.SDO_ORDINATE_ARRAY(276.2339,-179.7433,0,276.2498,-179.7361, 0 ))
And I need to update value Gtype :3003 to 3002 .
My problem is I don't know how to implement it because GRAG table has 30000 rows . I cannot update every row manually .
Do you have any advice ?AFAIK oracle11g cannot simply update SDO_GEOMETRY.
so you have to create new SDO_GEOMETRY with all but one old values.
try to modify this (I wrote it once to circumvent the cannot modify SDO_GEOMETRY problem):
-- clones a geometry but with different values
-- we can "alter" the SRID
-- note: oracle 11g cannot modify geometries
function alter_geometry(p_geo sdo_geometry, p_srid number default null)
return sdo_geometry is
v_result sdo_geometry;
v_srid number;
begin
if p_srid is null then
v_srid := p_geo.SDO_SRID;
else
v_srid := p_srid;
end if;
v_result := sdo_geometry(p_geo.SDO_GTYPE,
v_srid,
p_geo.SDO_POINT,
p_geo.SDO_ELEM_INFO,
p_geo.SDO_ORDINATES);
return v_result;
end alter_geometry;
--then do an update like
--test before with an create table as select
update crack c set c.shape = alter_geometry(shape, ...) -

How to write a cursor to check every row of a table which has millions of rows
Hello every one.
I need help. please... Below is the script (sample data), You can run directly on sql server management studio.
Here we need to update PPTA_Status column in Donation table. There WILL BE 3 statuses, A1, A2 and Q.
Here we need to update PPTA_status of January month donations only. We need to write a cursor. Here as this is a sample data we have only some donations (rows), but in the real table we have millions of rows. Need to check every row.
If i run the cursor for January, cursor should take every row, row by row all the rows of January.
we have donations in don_sample table, i need to check the test_results in the result_sample table for that donations and needs to update PPTA_status COLUMN.
We need to check all the donations of January month one by one. For every donation, we need to check for the 2 previous donations. For the previous donations, we need to in the following way. check
If we want to find previous donations of a donation, first look for the donor of that donation, then we can find previous donations of that donor. Like this we need to check for 2 previous donations.
If there are 2 previous donations and if they have test results, we need to update PPTA_STATUS column of this donatioh as 'Q'.
If 2 previous donation_numbers has test_code column in result_sample table as (9,10,11) values, then it means those donations has result.
BWX72 donor in the sample data I gave is example of above scenario
For the donation we are checking, if it has only 1 previous donation and it has a result in result_sample table, then set this donation Status as A2, after checking the result of this donation also.
ZBW24 donor in the sample data I gave is example of above scenario
For the donation we are checking, if it has only 1 previous donation and it DO NOT have a result in result_sample table, then set this donation Status as A1. after checking the result of this donation also.
PGH56 donor in the sample data I gave is example of above scenario
like this we need to check all the donations in don_sample table, it has millions of rows per every month.
we need to join don_sample and result_sample by donation_number. And we need to check for test_code column for result.

order by donor_numberYou didn't mention the version of SQL Server. It's important, because SQL Server 2012 makes the job much easier (and will also run much faster, by dodging a self join). (As Kalman said, the OVER clause contributes to this answer).
Both approaches below avoid needing the cursor at all. (There was part of your explanation I didn't understand fully, but I think these suggestions work regardless)
Here's a SQL 2012 answer, using LAG() to lookup the previous 1 and 2 donation codes by Donor: (EDIT: I overlooked a couple things in this post: please refer to my follow-up post for the final/fixed answer. I'm leaving this post with my overlooked

How to update one table from another
I am creating scripts in Oracle 10g. I have a table that has data corruption on three date fields.
I created a table with the following sql of all the affected rows:
CREATE TABLE LSU_INTER_FIX_DATE AS
select request_id,received_date,planned_start_date, actual_start_date
from lsu_inter2_requests_t
where received_date < to_date('01-JAN-1900')
OR planned_start_date < to_date('01-JAN-1900')
OR actual_start_date < to_date('01-JAN-1900')
I then repaired all of the rows with three data fixes
UPDATE LSU_INTER_FIX_DATE
SET received_date = TO_CHAR(received_date,'YY-MON') ||'-'||(TO_CHAR(received_date,'RRRR') + 2000)
where received_date < to_date('01-JAN-1900')
UPDATE LSU_INTER_FIX_DATE
SET planned_start_date = TO_CHAR(planned_start_date,'YY-MON') ||'-'||(TO_CHAR(planned_start_date,'RRRR') + 2000)
where planned_start_date < to_date('01-JAN-1900')
UPDATE LSU_INTER_FIX_DATE
SET actual_start_date = TO_CHAR(actual_start_date,'YY-MON') ||'-'||(TO_CHAR(actual_start_date,'RRRR') + 2000)
where actual_start_date < to_date('01-JAN-1900')
I now want to update the original base table with the corrected data so I wrote the following SQL UPDATE command:
UPDATE lsu_inter2_requests_t aaa
SET aaa.received_date = bbb.received_date
FROM LSU_INTER_FIX_DATE bbb WHERE aaa.request_id = bbb.request_id
When I run this sql Oracle returns the error “ORA-00933 SQL command not properly ended.” How do I update multiple rows in one table from another table that share the same primary key?Comet wrote:

When you want to produce a DATE datatype when starting with a string,
you must use TO_DATE() on the SET line!
(TO_CHAR(received_date,'RRRR') + 2000)since when do you do add characters (from TO_CHAR) with a constant number (2000)?
You should NEVER EVER rely on implicit datatype conversion

How to update database table !!!
hi all,
Please advice how to update database table with certain cndition needs to be checked.
Please consider below scenario.
have used enqueu and dequeue function to lock entries and also i have used BAPI so considering that return parameter . i want to update table
/tdk/st0027.
1. I want to update database table
2. there are certain condition needs to be checked like ,
loop at it_final into wa_final.
th_return-type = 'S'.
if th_final-vbeln = /tdk/st0027-vbeln and
th_final-posnr = /tdk/st0027-posnr and
th_final-etenr = /tdk/st0027-sdslno.
above condition which i need to check .and need to append below system fields need to be appended in table.
th_final-prstsind = '20'.
th_final-chgdate = g_date.
th_final-chgtime = g_uzeit.
th_final-chgprog = g_cprog.
th_final-chguser = g_uname.
append th_final to td_final.
update /tdk/st0027 FROM th_final.
endif.
endloop.
but i am getting error saying that "The type od database table and work area (TH_FINAL) are not unicode convertible"?
I am not able to understandwhat would be the solution for this ?
Thanks and regards,
Prasad K. NAralkarThe error occurs in the UPDATE statement included in the code. In this statement it is seen that there is a mismatch of structure defined for the DDIC table /tdk/st0027 and that of your work area th_final.
try to create a structure w.r.t the DDIC table.
Eg: DATA: wa_temp TYPE /tdk/st0027.
MOVE-CORRESPONDING th_final TO wa_temp.
Then try to UPDATE using the temporary work area i.e wa_temp which has structure similar to that of the database table. -
Update performance on a 38 million records table
Hi all,
I´m trying to create a script to update a table that have around 38 million records. That table isn´t partitioned and I just have to update one CHAR(1 byte) field and set it to 'N'.
The Database is 10g r2 running on a Unix TRU64.
The script I create have a LOOP on a CURSOR that Bulk 200.000 records by pass and do a FORALL to update the table by ROWID.
The problem is, on the performances tests that method took about 20 minutes to update 1 million rows and should take about 13 hours to update all table.
My question is: Is that any way to improve the performance?
The Script:
DECLARE
CURSOR C1
IS
SELECT ROWID
FROM RTG.TCLIENTE_RTG;
type rowidtab is table of rowid;
d_rowid rowidtab;
v_char char(1) := 'N';
BEGIN
OPEN C1;
LOOP
FETCH C1
BULK COLLECT INTO d_rowid LIMIT 200000;
FORALL i IN d_rowid.FIRST..d_rowid.LAST
UPDATE RTG.TCLIENTE_RTG
SET CLI_VALID_IND = v_char
WHERE ROWID = d_rowid(i);
COMMIT;
EXIT WHEN C1%NOTFOUND;
END LOOP;
CLOSE C1;
END;
Kind Regards,
FabioI'm just curious... Is this a new varchar2(1) column that has been added to that table? If so will the value for this column remain 'N' for the future for the majority of the rows in that table?
Has this column specifically been introduced to support one of the business functions in your application / will it not be used everywhere where the table is currently in use?
If your answers to above questions contain many yes'ses, then why did you choose to add a column for this that needs to be initialized to 'N' for all existing rows?
Why not add a new single-column table for this requirement: the single column being the pk-column(s) of the existing table. And the meaning being if a pk is present in this new table, then the "CLI_VALID_IND" for this client is 'yes'. And if a pk is not present, then the "CLI_VALID_IND" for this client is 'no'.
That way you only have to add the new table. And do nothing more. Of course your SQL statements in support for the business logic of this new business function will have to use, and maybe join, this new table. But is that really a huge disadvantage? -
How to update the table available in BADI method
Hi Friends,
I have to implement one badi ME_REQ_POSTED for purchase requistion, in this badi I have to read first line item and do
some check...if that check is true i need to update subsequent line item (line 20, 30, 40 or so) with purchase group and MRP controller.
In this BADI i have method POSTED, in this method parameter IM_EBAN is a table which i need to modify with my different
values for purchase group and MRP controller.
Kindly let me know how to update this table, so the changes can be reflected in purchase requistion.
Since when I tried to directly modify the table in a loop, system throw one error stating IM_EBAN can not be modified.
kindly help.
pradeephi
I have implemented this exit but it does not stop at it while saving Purchase requistion. But my previous BADI stops at it when saving.
Kindly guide. -

How to update Spry-table and present the updated table in a div element?
Hello!
I am using a very interesting AJAX-framework called Spry when designing a web page. Here the web page is: Link.
I need some help.
Every time a new project or shift is added, the changes are written to an xml-file. When the page is reloaded, Spry reads data from xml-files.
This is caused by this code:
dsProjects = new Spry.Data.XMLDataSet("timetable/projects.xml", "projects/project");
dsShifts = new Spry.Data.XMLDataSet("timetable/{dsProjects::url}", "project/shift"); //look inside projects.xml and //extrac xml-file. url
dsName = new Spry.Data.XMLDataSet("timetable/{dsProjects::url}", "project");
I call this function that I have written: loadProjectsIntoDivElement ().
This function does the following: [See attached code.]
It iterates through the Spry-datastructure and puts the data in a table inside of the div-element called 'projectsList'.
Now, when I add a new project, I want it to be inserted into the Spry-datastructure and then cause the new data to be written into the div element called 'Specials_DIV'.
I have found out how to update a Spry-datastructure (e.g. dsProjects above), but I don't know how to update the table containing the data without refreshing the page. This should be done using Spry.
Some code:
1:
2:
3:
function loadProjectsIntoDivElement () {
$('#projectsList').html('');
$('#projectsList').append('<table id="Specials_Table"><tr><th spry:sort="id">ID</th><th spry:sort="NAME">Name </th><th spry:sort="hoursestimated">Nr. of hours estimated</th><th spry:sort="hoursworked">Nr. of hours worked</th><th spry:sort="costperhour">Cost per hour.</th></tr>{function::init_hours}<tr spry:repeat="dsProjects" onclick="chooseProject({ds_RowID})"><td>{id}</td><td>{NAME}</td><td>{hoursestimated}</td><td>{hoursworked}</td><td>{costperhour}</td></tr></table><br/>{function::get_hours}<br/>');
I have tried to accomplish this in various ways but I don't succeed.
I want to do it without refreshing the page.
Update: I found some code here that I will try: Link
Thanks in advance!
Anders Branderud
My blogHello!
Thanks!
I don't succeed with the implementation in any browser.
I have found a way to it, but I would like a way that updates the data quicker and without reloading all of the page. After all, I am only adding one row on the end of the data structure, so there should be no need to read in all data again.
Now I do it like this:
When a project is added, do this:
1. Store a new row in the project file through a php script.
2. When the post-call to the php-file returns, do refresh of the whole page.
Then the newest version of the xml file will be read in.
However, I don't want to read the data from a xml file each time that a new project is created.
I know how to add the new data to a Spry-datastructure [in my code 'dsProjects'], but I don't know how to display the updated data without reloading the whole page.
I have tried some various ways to do it, but haven't succeded.
Thanks!

How to update a table containing BLOB?
Hi,
I'm trying to update two columns in a table.
one is NUMBER and the other is BLOB
Is there a way to do so in OCCI in a single operation ?
the table looks like this:
CREATE TABLE ACCUMULATORS
(TARGET_SUBS NUMBER(9),
ITERATOR NUMBER(9),
NUMERATOR NUMBER(9),
LARGE_DATA BLOB,
PRIMARY KEY(TARGET_SUBS,ITERATOR));
and the query is something like:
UPDATE ACCUMULATORS SET NUMERATOR = :x1 , LARGE_DATA = :x2 WHERE (TARGET_SUBS = :x3) AND (ITERATOR = :x4);

How to update the table value in the valuechange event?
I have an input field in the datatable with the valueChangeListener
<rich:dataTable id="cart" value="#{cart.cartList}" var="item">
<h:inputText value="#{item.cost}" id="qty" valueChangeListener="#{items.updateCost}" onchange="submit()">
<h:outputText value="#{item.errorMsg}"> </h:outputText>
in the backing bean
Item item = (Item) model.getRowData();
// do some update, if the cost too larger, change to max_cost
item.setCost(max_cost);
item.setErrorMsg("Error Msg");
After calling the valuechange method, the screen output doesn't update the cost.
How to update the table value in the valuechange event?As you're misusing the valueChangeListener to set another input field, you need to skip the update model values phase. Otherwise the value set in the valueChangeListener will be overridden by the submitted value. You can do this by calling the FacesContext#renderResponse() inside the valueChangeListener method. This will shift the current phase immediately to the render response phase, hereby skipping the update model values and invoke application phases.

How do I find music that has been uploaded to iTunes from a purchased CD and iTunes is “unable to find the original file?” I no longer have the CD. I have tried all the usual methods of looking in my iTunes library and through Find. No Luck.
Backup drive?
Subscribe to iTunes Match?
If neither of the above and you don't have the CD and can't find your tracks on the computer then they you're stuck. A file recovery utility will cost $100, plus another $100 for an external drive to which to resue the files, and may not even work. You can buy a lot of CDs for $200.
