Row by row update

<<stop posting your interview questions>>
Hi
The below select statement is taking too much time in Production system,
is there any way to optimize the above code ?
"select * from VVBAP
into g_wa_vvbap
where vbeln in g_vbeln.
g_wa_vvbap-zmeng = g_wa_vvbap-zmeng + 5.
update vvbap from g_wa_vvbap.
Endselect."

Hi Thomas,
Reading this was a real treat
The code is below, not above. For you, that is. For me, it is above, not below. Hope you understand.
My experience ..
I searched for the answer so that i may be the early bird to post the answer,on this thread..and win some good points on this thread...
O Lock
I felt bad that day that in spite of my efforts, Sandeep gave 10 points to Subin.
Now i see it all
Am feeling a looooooooooottttttttt better now.

How can i use multiple row subquery in update statement

Hai All
I using group function in my update statement.. and i need to update more rows so i need to use multiple row
subquery pls tell me how to use multiple row subquery in update statement
For example
while i am using this like this i got an error
update dail_att set outtime in (select max(r2.ptime) from temp_att where empcode=r2.enpno and
barcode=r2.cardn and attend_date=r2.pdate group by enpno,pdate,cardn);
Pls tell me how to use with example
Thanks & regards

Hai Man
Thanks for ur response Let me clear what i need
First step Fetch the records as text file and stores into table T1
and the next step is i have seperated the text using substring and stores in different columns of a table
There are two shifts 0815 to 1645 and 1200 and 2000
Here I rep IN and O rep OUT

end if;
end loop;
exception
     when no_data_found then
     if r2.inout ='I' then
               insert into dail_att(barcode,empcode,intime,attend_date)(select r2.cardn,r2.enpno,min(r2.ptime),r2.pdate from temp_att group by r2.cardn,r2.enpno,r2.pdate );
     end if;

commit;
     end;
Pls tell me what correction i need to do i the update statement i have used a subquery with group function but when i used it will return only one row but my need is to return many rows and i need to use multiple row subquery
and how can i use it in the update statement

How can I use multiple row insert or update into DB in JSP?

Hi all,
pls help for my question.
"How can I use multiple rows insert or update into DB in JSP?"
I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
With thanks,

That isn't true. Different SQL databases have
different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
and there are also a lot of different ways of talking to
SQL databases that are possible in JSP, from using
plain old java.sql.* in scriptlets to using the
jstlsql taglib. I've done maintenance on both, and
they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
Well, sure. As long as you only want to update rows
with the same value in column 2. I had the impression
he wanted to update a whole table. If he only meant
update all rows with the same value in a given column
with the same value, that's trivial. All updates do
that. But as far as I know there's know way to update
more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
Unless you're using MySQL, for instance. I only have
experience with MySQL and M$ SQL Server, so I don't
know what PostgreSQL, Oracle, Sybase, DB2 and all the
rest are capable of, but I know for sure that MySQL
can insert multiple rows while SQL Server can't (or at
least I've never seen the syntax for doing it if it
does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
Don't assume that all SQL databases are the same.
They're not, and it can really screw you up badly if
you assume you can deploy a project you've developed
with one database in an environment where you have to
use a different one. Even different versions of the
same database can have huge differences. I recommend
you get a copy of the O'Reilly book, SQL in a
Nutshell. It covers the most common DBMSes and does a
good job of pointing out the differences.Yes, I understand that.
It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.

To find out the last row that is updated in a View Object

Hi OAF Gurus,
I have requirement like,
I have to find out the last row that is updated on a particular View Object and I have send a mail to the users about the change.
JegSAMassMobVOImpl vo = getJegSAMassMobVO1();
JegSAMassMobVO is the View Object Name and it displays certain rows that has already been added to the VO in the Page.
Now the issue is when a user updates a particular row,I have to find which row gets updated and have to send a email to that particular employee about the change.
Just want to know,how to find out the last updated row in a particular VO.
Any Help would be appreciated as this a immediate requirement.
Regards,
Magesh.M.K.
Edited by: user1393742 on May 4, 2011 1:06 AM

Hi Magesh
It shoud be a Advanced table ,so when user will update the row ,the specific row will fire the PPR and on that event u can capture the row using row reference ,this is the sample code below
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean); OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
String event = pageContext.getParameter("event");
if ("<ItemPPREventName>").equals(event))
// Get the identifier of the PPR event source row
String rowReference =
pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
Serializable[] parameters = { rowReference };
// Pass the rowReference to a "handler" method in the application module.
262
am.invokeMethod("<handleSomeEvent>", parameters);
In your application module's "handler" method, add the following code to access the source row:
OARow row = (OARow)findRowByRef(rowReference);
if (row != null)
Thanks

How to count the number of Rows to be Updated before Update takes place..

Hi all,
I have a requirement, where i have to count the number of rows to be updated before updating it. SQL%ROWCOUNT gives the no. of rows updated ( after update takes place). How do i get to know the count of no. of rows to be updated/inserted/ deleted. I was looking for a simple solution, as above SQL%Rowcount. But i couldn't find any. I can use a Function and Return the value which will give me number of rows to be updated, But is there any Simple Logic other than this.. or any count function. Your Help is Appreciated. Thanks!

If you really want to do this (I have no clue why you would need it), then you can piggy back on any existing pessimistic locking you may already have in place.
However, it would require two loops through the records of which you want to know the count before you update, and a second pass to update them.
I would really re-think the need for this, though.

How to count updated rows after an UPDATE?

Is there a way to count updated rows after an update?
Let's say I have an update like
UPDATE table_a
set field_1 = 'new_field'
WHERE field_2 ='some_value' ;
And now I would like to insert an info record into logging table like
INSERT INTO logging_tbl (step, description, changed_rows) VALUES('UPDATE', 'update of table_a', ?);
update is in sqlplus script.
Thanks.

Use SQL%ROWCOUNT.
DECLARE
v_num NUMBER := 0;
BEGIN
UPDATE table_a
set field_1 = 'new_field'
WHERE field_2 ='some_value' ;
v_num := SQL%ROWCOUNT;
INSERT INTO logging_tbl (step, description, changed_rows)
VALUES('UPDATE', 'update of table_a', v_num);
END;

Count of updated rows after an UPDATE command

Hi, is there any way to know how many rows have been updated after an UPDATE statement in a PL/SQL program (i know it is possible in Pro*C. Thanks.

Hi,
it will be stored in sql%rowcount
after your update statement try to assign this to a variable
Update table set ....
v_count := sql%rowcount;
check the value of the variable v_count
Thanks

Mutating error : row level BEFORE UPDATE trigger

Hi,
I had an issue on mutating terror(was trying to write a row level BEFORE update trigger), however i got it resolved after refering tom kytes web site. I thought i would share it with everyone, might be helpful for a few... Thanks!
I will be more than happy to learn on further better ways of resolving this issue.

How to Know, No. of Rows has been Update, throught Triggers

Hi all,
I am having problem in after update trigger. I want to know How many rows has been updated by a sql statement, for that I have written on (AFTER UPDATE TRIGGER ON EMP). But it is not giving any result. I am executing Update statement from
Sqlplus (UPDATE EMP SET SAL=23 WHERE EMPNO=7369;) We cant use Commit, and dbms_output.put_line in trigger. thats why I have used exception.

Hi Sachindra
What SQL*Plus version you are using?
Some versions that come with forms6i they dont write the number of rows updated, they just write operation 44 succeeded or something like that.
But if you use the SQL*Plus database client (sqlplusw.exe or sqlplus.exe) which those 2 get installed with the db you will be able to see the number of rows update/deleted/inserted

Merging multiple rows in to a single row (when rows meet merging criteria)

Hi
I have a scenario to merge multiple rows in to a single rows when the data in those rows fall in merge criteria .Below is how my data is
Now the merging logic for the above rows is , we need to combine multiple rows in to a single row when the data in those rows permits us to do in that way. Simply saying , its like sandwich where we combine multiple things to a single piece.The output for
the above rows should be
Here we combined Row 1 ,2, 3 in to a single row as the data in those rows permits to merge in to single row. But the row 4 cannot be combined to any of those rows because the data in those rows doesn't permits us do a merge ( As the value of the column
JobSource for the row 4 is different from the other rows ) .
My original data has 56 columns , but for readability i kept only 9 columns.
can you please throw some idea on how to achieve this scenario. I know we need to use CTE for achieving this, but i am not able succeed in doing an iteration on multiple rows.
Appreciate your response .

Thanks for your reply .
Rule for merging is simple . First of all there is no unique row identifier for each row , the fact table is not having an identity column in the database . I called row 1 , row 2 etc in my post above only to make better explanation of my scenario.
The rule for merge is below.
1) we can combine only when the data in a column for one row is null & the data in same column for the other row is not null . It should also satisfy the condition where the data in other columns should conflict each other.
2) Data for all columns for the merging rows should not be conflicting (i.e. we should not merge the rows when the data in a column is not equal to the same column in the other row
,considering not null value)
Steps in merging the above source data :
1) Consider the case of row 1 and row 2 in the source, we can combine these rows as the data is satisfying the rule 1 for columns (Jobsource,Flight, Package,Update,Iscancelled
,Result, Severity) and columns (JobID and RuleName ) fall under rule 2. we merge these two rows in to a single row and keep in that in the table.
2) Then the resulting row is again merged with the second row which is present above by applying the rule 1 and rule 2 . Below would be output of merge operation.
Now there would be only two rows in the output . But these rows cannot be merged as the data doesn't satisfy the merge rules 2 . As Jobsource for the row 1 in the above output is "PresubmissionSource" which is not equal
to "PostSubmission" jobSource which is in row 2. So these two rows are left unmerged .So the above two rows would be the output of merge operation on my source data.
This process has to be repeated for all the rows in the table. As of now my table as 92 Million rows with 56 columns which need to be considered for merging rows. I replicated my scenario in 9 columns and 4 rows to understand better.

How to Comapare Row by Row in ODI Interface

Hi all
i want to Compare Record by Record from my Source Table.
Can any one Explain Logic How can i do through ODI Interface?

If you want row by row processing (rather than set based) then look at using Knowledge Modules that implicitly use a cursor via the agent to load the staging table (e.g LKM SQL to SQL) or a KM that explicitly uses a cursor to load the target table (e.g IKM Incremental updata row by row).
It wont be as fast as set based though!
What do you want to do with each row? Can you load them all into the staging area and then process row by row?

How to copy data between two tables row by row

Hi All,
I have three tables TableA and TableB and TableC
I wanted to write a stored procedure to copy data row by row from TableA to TableB and then update TableC by replacing any record that has the old id (before copying) to the new id after copying the data.
here is the steps
iterate throw all the rows in tableA ( probably with a foreach)
in each iteration we will do the following:
Get current ID (identity) for each record in TableA ( will call it @oldID)
Insert the row in TableB
Get the new ID for the row from TableB will call it (@NewID)
find rows in tableC that has the (@oldID)
replace all ids in tableC with @oldID to @NewID
Thanks in advance

0
TableA and TableB are identical they should have the same columns
TableC columns will be ( ID, TableA_ID , Notes)
