Updating a row of a table using rowid

Hi folks,
I am trying to update some rows in a table using rowid of the corresponding rows.Sometimes this updates wrong rows. This is because ORACLE by itself makes some statistics on the particular table using "Analyze table..." statement and it changes the order of the rowids. But if I delete the statistics,the updation works fine. Is there any way to update the correct rows and also to keep the statistics created by ORACLE? P.s: I am using ORACLE thin Driver to connect to Oracle 8.1.6
Thanks,
Karthi.

First make it clear: analyze table command never changes ROWIDs. Actually, the ROWID of a row never changes untill it's deleted from its table. So make sure if you are using the correct ROWID.
Thnx

Question on Updating the rows of a table using a SELECT Statement

Hi,
I am trying to set all of the R_IDs in one table to the ID from another table using a join.
Here is the SQL I came up with. I don't this is correct though.
UPDATE TABLEA A
SET R_ID=(Select Id from TABLEB B
WHERE A.DEE=B.DEE AND
B.RNUM=1);
Does this make sense?

You can try the join view.
UPDATE ( SELECT table_a.id   AS a_id,
                table_b.id   AS b_id,
                table_a.col1 AS a_col1,
                table_b.col1 AS b_col1,
                table_a.col2 AS a_col2,
                table_b.col2 AS b_col2,
                table_a.col3 AS a_col3,
                table_b.col3 AS b_col3
           FROM table_a,
                table_b
          WHERE table_a.id = table_b.id)
   SET a_col1 = b_col1,
       a_col2 = b_col2,
       a_col3 = b_col3;
However it may result in
ORA-01779: cannot modify a column which maps to a non key-preserved tableThis is because the key-preserving property of a table does not depend on the actual data in the table. It is, rather, a property of its schema. For example, if in table_b there was at most one record for each id value, then table_a.id would be unique in the result of a join of table_a and table_b, but table_a would still not be a key-preserved table. By adding the unique/primary key on the id column of table_b we can assure that if table_b.id were part of the result set of the join view then it would be unique. This makes table_a key preserved.
Thus, in order to update a join view we must assure that the columns involved in the join view from the source table are unique. We do this by creating a unique or primary key on those columns.
However, if you do not mind taking responsibility for making sure that there is one-to-one cardinality between the source and destination rows, then you might try the correlated subquery
UPDATE table_a
   SET (col1, col2, col3 ) =
          ( SELECT col1, col2, col3
              FROM table_b
             WHERE table_b.id = table_a.id )
       WHERE EXISTS
           ( SELECT col1, col2, col3
               FROM table_b
               WHERE table_b.id = table_a.id )

How to Update Particular row in a table from OAF page

Hi Can anyone please help me on the following requirement:
In my oaf page i am displaying table values(supplier site details from base tables) with update and delete icons . When i click on update button a new page opens in which we used to update the values and click on apply button which again comes back to the original page.
So when i click on apply button on update page i have to first search for the site in the site table whether it exists or not, if not exists i have to create a new row and save the data, if site exists in the table i have to update the row of a table for that particular site. I have written code for this but unable to achive the requirement, it is not updating the existing row of the table. And i am doing all this on the Temp tables.
So now when i save, previous transaction is also updating along with the current transaction. That means when i m trying to save 2nd transaction values , 1st transactions values are getting updated with the 2nd transaction values(2 rows are getting updated)
Can anyone help me with the code used for updating the current row of the table. Please correct me if i m doing anyting wrong in code.
following is the current code i m using and which is failing :

Please answer following:
1. Are you using EO based VOs or ReadOnly VO?
2. What is your VO Query for the search and update?
3. Why have you based your logic on site_name; you should have used site_id?
4.Are you getting correct site name in handling createECdetailsEvent event in CO?
5. In case of update are you getting correct values on the Update Site Details?
6. On coming back from Update page to Supplier Site Search page, do you see old values of the site or the new values in the results table?
Please share the screenshot if possible.

Need help in SQL Query: Update a row in a table & insert the same row into another table

I want to update a row in a table say Table A and the updated row should be inserted into another table say Table B. I need to do it in a single SQL query and i don't want to do it in PL/SQL with triggers. And i tried with MERGE statement but its working with this scenario. (Note: I'm using Oracle Database 10g Enterprise Edition Release 10.2.0.1.0).
Thanks in Advance.

Using Sven's code as an example, you could save the updated row in a sql plus variable. (also untested):
SQL> var v_id number
update tableA
set colB='ABC'
where colC='XYZ'
returning id into :v_id;
insert into table A_History (ID, colA, colB, ColC)
select id, ColA, ColB, ColC
from tableA
where id = :v_id;

Update all rows in a table which has 8-10 million rows take for ever

Hi All,
Greetings!
I have to update 8million rows on a table. Basically have to reset the batch_id with the current batch number. it contains 8-10 million rows and i have tried with bulk update and then also it takes long time. below is the table structure
sales_stg (it has composite key of product,upc and market)
=======
product_id
upc
market_id
batch_id
process_status
I have to update batch_id,process_status to current batch_id (a number) and process_status as zero. I have to update all the rows with these values for batch_id = 0.
I tried bulk update an it takes more than 2hrs to do. (I limit the update to 1000).
Any help in this regard.
Naveen.

The fastest way will probably be to not use a select loop but a direct update like in William's example. The main downside is if you do too many rows you risk filling up your rollback/undo; to keep things as simple as possible I wouldn't do batching except for this. Also, we did some insert timings a few years ago on 9iR1 and found that the performance curve on frequent commits started to level off after 4K rows (fewer commits were still better) so you could see how performance improves by performing fewer commits if that's an issue.
The other thing you could consider if you have the license is using the parallel query option.

Best way to update individual rows of a Table?

I've taken a look at some examples, though haven't gotten any clarification on this. I am looking to have something close to a listbox or table to where I can update just a single column of row values at a 1 time per second pace. I am looking to display our data-acquisition values in a table or listbox. The single listbox seemed to work good for this, but I was unable to use row headers to list the channel names next to the channel values. I was thinking about connecting the cursor values of two list-boxes to do this, but didn't find any info on this for the single list-box.
I have a few questions:
1) I have a 1D array to where I want to use that array of data to constantly update the first column (with a multitude of rows) of a table. I am looking for the best route so as not to take up too much processing time in doing this.
What is the best way to update individual rows of a table? Invoke Node "Set Cell Value" ... or is there another method?
2) Why is it that after every other iteration the row values are erased?
Also, for adding additional strings to the original arrray ... is it best to use the "Array Subset" and then the "Build Array" function, or the "Array Subset" and "Insert Into Array" function?
See the attached example.
Thanks.
Solved!

Classic race condition. dump the for loop and p-node and just wire the 2D array to the table terminal.!
I'm not seeing the race condition. What I am seeing is the table emptying after the last element was written to it on every other run. I saw watched this with highlight execution on.
But I'm in full agreement with just writing to the terminal. It is a 1D array, so you will need to use a build array and transpose 2D array in order for it to write properly.

URGENT:Update multiple rows of a table as a transaction

Hi,
I am trying to update mutliple rows in one table as a transaction, but only update on the last row is commited to database. Updates on the previous rows is not committed.
I must be missing some thing which is obvious. Has any got a clueeeeeeeeeee?
code:
for (int i = 0; i < selectedFaultNumbers.length; i++) {
String nationalFaultNumber = selectedFaultNumbers;
String fault = nationalFaultNumber.substring(0,13);
national_faultsRowSet2.setCommand("SELECT national_faults.national_fault_number, national_faults.status_id, national_faults.master_fault_number FROM national_faults WHERE national_faults.national_fault_number= '"+fault+"'");
national_faultsRowSet2.execute();
if (national_faultsRowSet2.next()) {
national_faultsRowSet2.updateInt("status_id", FAULT_STATUS_ASSOCIATED);
national_faultsRowSet2.updateString("master_fault_number",nationalfltno);
national_faultsRowSet2.updateRow();
national_faultsRowSet2.execute();
Any help wil be GREATLY appreciated.
Cheers

Hi Giri,
Thanks for getting back to me.
If I understood correct, sample example updates a rowset which is bound to datatable and changes are committed to database using datatablemodel.
In my case rowset is not bound to a datatable and user is not updating the rowset.
PageBean has to update few rows in a table when a new row is inserted in to that table.
Please correct me if I got it wrong. Is there any other solution ???
Thanks very much

Updating multiple rows in a table in ADF

Hi
How do we update multiple rows in a table.
Onclicking a update button the changed rows must be updated.

Hi Prince,
currently I am selecting one row from the table and rendering a region at the top of the table and capturing the user entered data with the following code:
ViewObjectVOImpl vo = getViewObjectVO1();
Row CurrentRow = vo.getCurrentRow();
//After this I perform the checks like user entered value is not null or check input as per business logic.
if(CurrentRow.getAttribute("attributeName") ==null){
//Add what message you want to display
//Add other business logic.
After making all the checks, i commit it.
getOADBTransaction().commit();
Now in my new page I am capturing the user input in the table itself like an excel sheet. Suppose there are ten rows in my advanced table on my page, and each row has one editable field. I have one save button at the bottom of the table.
Now on clicking the save button I have to capture the user input, check whether there is any null value and if all the entered data is correct then only I should commit it.
Can you please let me know how we can accomplish that.
Regards
Hawker

Inserting multiples rows into a table using function or procedure..

Update a row in af:table in different pagesandselection isby using checkbox

Hi all,
I am very new to adf. I have requirement where af:table should have a check box and on selection of checkbox and clicking on update button it should redirect to a new page which contains the af:form of the selected row and the user should be able to update the values. with out check box i was able to do by setting the setcurrentrowwithkeyvalue to the button.
how can i set setcurrentrowwithkeyvalue.
i am using two .jsff pages and a taskflow for those two pages.
i am using jdev11.1.1.5.0
Thanks In advance
Edited by: 926968 on Apr 16, 2012 6:10 AM

af:BooleanCheckbox has a valueChangeListener which can be called in a managedBean bound to your taskflow.Inside this method write code to set the current row of the table and then navigate to the new page.
Basically use something like this ->
In the jspx
<af:selectBooleanCheckbox label="Label:"
                          textAndAccessKey="checkbox"
                          accessKey="2"
                          *valueChangeListener="#{pageFlowScope.myBean.onClickOfCheckbox}"*
                          id="sb1"/>
In the bean
public void onClickOfCheckBox(ValueChangeEvent vc) {
    //code to set the currentRowof the iterator - you can refer this http://neeraj-soa-tips.blogspot.com/2010/01/setting-current-row-of-view-object-with.html

Hi, Damby,
That sounds like what the UPDATE statement does, exactly. Just use an UPDATE statement to change any number of columns in existing rows. You don't need a procedure, but, if you're using a procedure for some other reason, you can do the UPDATE in the procedure. UPDATE works the same in SQL or PL/SQL.
Sometimes MERGE is more convenient than UPDATE. Like UPDATE, it can change any number of columns, either in SQL or PL/SQL.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
In the case of a DML operation (such as UPDATE) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.

How to update multiple rows in one query using php

i am new to this can any one help me how to update multiple rows at a time i am doing an school attendance page

Often the situation is such that you have multiple courses across a range of dates.So students may take more than one course, and you need to track attendance for each course date. The following graphic demonstrates this:
In such a situation, you need four database tables as follows:
students (student_id, student_name, etc.)
courses (course_id, course_name, etc.)
students_courses (student_id, course_id)
attendance (student_id, course_id, dater)
A fifth table may also be needed to define the dates of courses, but you may also be able to build this array programmatically by using PHP's robust date functions, which can give you, for instance, all the Tuesdays and Thursdays between a start date and end date.
The students_courses table simply keeps track of which students are taking which courses, so it has just two columns for the primary keys of both of the main tables. The attendance table is similar, but it also includes a date field. The following view of the attendance table demonstrates this:
So if David's solution does cover your needs, consider yourself lucky, because this could quickly grow from a beginner-appropriate project to a moderately advanced one.

Migration of million rows from remote table using merge

I need to migrate (using merge) almost 15 million rows from a remote database table having unique index (DAY, Key) with the following data setup.
DAY1 -- Key1 -- NKey11
DAY1 -- Key2 -- NKey12
DAY2 -- Key1 -- NKey21
DAY2 -- Key2 -- NKey22
DAY3 -- Key1 -- NKey31
DAY3 -- Key2 -- NKey32
In my database, I have to merge all these 15 million rows into a table having unique index (Key); no DAY in destination table.
First, it would be executed for DAY1 and the merge command will insert following two rows. For DAY2, it would update two rows with the NKey2 (for each Key) values and so on.
Key1 -- NKey11
Key2 -- NKey12
I am looking for the best possible approach. Please note that I cannot make any change at remote database.
Right now, I am using the following one which is taking huge time for DAY2 and so on (mainly update).
MERGE INTO destination D
USING (SELECT /*+ DRIVING_SITE(A) */ DAY, Key, NKey
               FROM source@dblink A WHERE DAY = v_day) S
ON (D.Key = S.Key)
WHEN MATCHED THEN
   UPDATE SET D.NKey = S.NKey
WHEN NOT MATCHED THEN
   INSERT (D.Key, D.NKey) VALUES (S.Key, S.NKey)

   UPDATE SET D.NKey = S.NKey
WHEN NOT MATCHED THEN
   INSERT (D.Key, D.NKey) VALUES (S.Key, S.NKey)
LOG ERRORS INTO err$_destination REJECT LIMIT UNLIMITED;The first remark I have to emphasize here is that the hint /*+ DRIVING_SITE(A) */ is silently ignored because in case of insert/update/delete/merge the driving site is always the site where the insert/update/delete is done.
http://jonathanlewis.wordpress.com/2008/12/05/distributed-dml/#more-809
Right now, I am using the following one which is taking huge time for DAY2 and so on (mainly update).The second remark is that you've realised that your MERGE is taking time but you didn't trace it to see where time is being spent. For that you can either use the 10046 trace event or at a first step get the execution plan followed by your MERGE statement.
LOG ERRORS INTO err$_destination REJECT LIMIT UNLIMITED;The third remark is related to the DML error logging : be aware that unique keys will empeach the DML error loggig to work correctly.
