Efficient way of updating data to database table
what is the efficient way of updating data to database table .
i have huge amount of data in my internal table , how to use update statement in this case .
1. database table having 20 fields ,
2. one is key field and suppose 20 th field i want to change .
3. I have data for only 2 fields , i.e for ( 1 st and last 20 th field ) .
i can't use update statement in loop , as it is not good practice(hits database several times ) .
do it effects all the 20 fields for particular record .
Hi,
Use UPDATE statement , check below description from SAP help.
UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
Effect
Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab.
The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.

How to update date in a table from another database
Hello,
I am trying to code a way to Update my Testing database from another database. In the coding below the database that has the updated data ends in Restore.
Use ClientDB_MASTER_Restore
Truncate Table ClientDB_MASTER_Testing.dbo.Activity_Tracking_AZ
GO
SELECT * INTO ClientDB_Master_Testing.dbo.Activity_Tracking_AZ
FROM Activity_Tracking_AZ
Go
I know with this Technique the table must be truncated if not deleted first. There is probably a better way to do this which I'm very open to. I'm also looking for coding that will roll back any changes made should an error occur.
As always, any help is greatly appreciated.
David92595USE ClientDB_MASTER_Testing
go
SET XACT_ABORT ON
BEGIN TRANSACTION
Truncate Table dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ ON
INSERT dbo.Activity_Tracking_AZ (col1, col2, ...)
SELECT col1, col2,
FROM ClientDB_MASTER_Restore.dbo.Activity_Tracking_AZ
-- SET IDENTITY_INSERT dbo.Activity_Tracking_AZ OFF
COMMIT TRANSACTION
If you find it boring to type the column lists, just find the table in Object Explorer, and drag the columns node to where you want the column list.
You need the SET IDENTITY_INSERT command if the table has an IDENTITY column.
By wrapping the code in a transaction, you are not left with an empty table if the INSERT fails. The command SET XACT_ABORT ON makes sure that the batch is aborted and rolled back in case of an error.

What r d ways u populte data to database tabale
what r d ways u populte data to database tabale
HI,
There are several ways you can insert values into a database table.
1. Database Browser -- Tcode SE16.
2. View -- Tcode SM30.
3. Programatically
a. Through BDC
b. Through File Transfer Technique
c. Through INSERT, UPDATE, MODIFY SYNTAX IN ABAP
d. Through data transfer techniques like LSMW, BAPI,
Function Module Calls, Tcode -- SXDA.
4. Further for SAP Standard tables, SAP Standard programs supply values.
Hope this should help you, reward points if convinced with the answer.

Hi
how to create a external content type for Read and Update data from two tables in sqlserver using sharepoint designer 2010
i created a bcs service using centraladministration site
i have two tables in sqlserver
1)Employee
-empno
-firstname
-lastname
2)EmpDepartment
-empno
-deptno
-location
i want to just create a list to display employee details from two tables
empid firstname deptno location
and same time update in two tables
adilWhen I try to create an external content type based on a view (AdventureWorks2012.vSalesPerson) - I can display the data in an external list. When I attempt to edit it, I get an error:
External List fails when attached to a SQL view
Sorry, something went wrong
Failed to update a list item for this external list based on the Entity (External Content Type) 'SalesForce' in EntityNamespace 'http://xxxxxxxx'. Details: The query against the database caused an error.
I can edit the view in SQL Manager, so it seems strange that it fails.
Any advice would be greatly GREATLY appreciated.

Is there a simple way to update data in a mobile phone?
I'm in a work on J2ME.This work is to make we Chinese easier to recite English word.If we can see these English words on our mobile screen every now and then,then it would be of great help to us.
The most tough point is that we have to update those words for we cannot put every words, say , in TOFEL ,into our RMS.We cannot simply transmit those words with a USB line for JVM do not support it and it costs a lot with woreless network.
So I make out another seemly demanding plan.I can translate words in a .txt(certainly in some format) to a .class which would have been genenrated from a .java containing RMS otherwise.And then we only have to generate this class from various word lists and make the whole project a .jar file.
What I want to ask is :
Is there a better way to update information(or database) in J2ME?
Can I generate .jar file without JRE in windows?For i don't want to force every green hand be bogged down in setting JRE.

Its very urgent:how to insert data into database tables
Hi All,
I am very new to oaf.
I have one requirement data insert into database tables.
here createPG having data that data insert into one custom table.
but i dont know how to insert data into database tables.
i wrote the code in am,co as follows.
in am i wrote the code:
public void NewoperationManagerLogic()
ManagerCustomTableVOImpl vo1=getManagerCustomTableVO1();
OADBTransaction oadbt=getOADBTransaction();
if(!vo1.isPreparedForExecution())
vo1.executeQuery();
Row row=vo1.createRow();
vo1.insertRow(row);
in createPG processrequest co:
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
ManagerInformationAMImpl am=(ManagerInformationAMImpl)pageContext.getApplicationModule(webBean);
am.NewoperationManagerLogic();
process form request:
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
if(pageContext.getParameter("Submit")!=null)
ManagerInformationAMImpl am=(ManagerInformationAMImpl)pageContext.getApplicationModule(webBean);
am.getOADBTransaction().commit();
please help with an example(sample code).
its very urgent.
thanks in advance
Seshu
Edited by: its urgent on Dec 25, 2011 9:31 PMHi ,
1.)You must have to create a EO based on custom table and then VO based on this EO eventually to save the values in DB
2.) the row.setNewRowState(Row.STATUS_INITIALIZED); is used to set the the status of row as inialized ,this is must required.
3.) When u will create the VO based on EO the viewattributes will be created in VO which will be assigned to the fields to take care the db handling .
You must go thtough the lab excercise shipped with you Jdeveloper ,there is a example of Create Employee page ,that will solve your number of doubts.
Thanks

How to insert data in database table
Hi experts,
How to insert data into database table using internal table from function module.Hi,
As per my understanding are you looking for the complete API feature of data insertion into the database using the Locking Mechanism? If yes, then you need to create a Lock Object using the Primary keys of the Primary Table and Secondary Tables. You need to call the lock object first and then you need to make the entry into the table. This principle is based on 'All or None Concept'.
For the insert Statement Key word you can have a look at the following link:
http://help.sap.com/abapdocu/en/ABAPINSERT_SOURCE.htm
Hope this helps.
Thanks,

Moderator Message: Put some effort into not only solving your issue but also into framing a proper question. Thread locked
Edited by: kishan P on Sep 3, 2010 10:29 PMHI Jaipai,
You have to find standard function modules / BAPI / class to update data from that table.
If you have to change the table's structure, use enhancement to do that.

How to create a thread safe and concurrent form that updates data to database.
Hi ,
I am creating an application which will store information from 4 or 5 text boxes in the database.
At the same instance of time atleast 300 users will be trying to update to the database.
That is trying to execute the same code.
I am worried if there will be any issue of object lockign or my page giving some error or performance issue.
How can I solve this issue.
Regards
VinodSQL Server manages simultaneous access to data itself, when it comes to executing a single query. It locks/unlocks tables/records automatically. So, if you are using a single UPDATE, INSERT or DELETE command, usually you won't need anything to take care
of synchronization, but a problem named "Concurrency issue" which I explained a little ahead.
However, if you are updating more than one table, you must use transactions, so that your changes are applied atomically. This can be done both in database level in T-SQL and also in application level in C#, VB, etc.
In T-SQL you want to use BEGIN TRAN, COMMIT TRAN, ROLLBACK TRAN commands and in C# you want to use TransactionScope.
You should pay attention that, transactions indeed have a hit on the performance of your database. But using them is indispensable. To prevent performance degradation, you have to tune your database and queries which itself is another big topic.
One thing that is more important is a problem known as concurrency issue.
If more than one user tries to update a single record, each one might overwrite the update of another user without being even notified of this. Suppose user A and B both try to update a record. They are not aware of each other working with the application.
They open a record in edit mode in the application. Edit it and then click the "Save" button. When the application saves the record with the data provided by each user, one data will be lost definitely. Because it will be overwritten with the data
another user has provided and his Save command, executes later than the first user.
There are multiple ways to avoid concurrency issue. One of them is using Timestamp (old method) and RowVersion (newer method) column in a table. They can help you detect a change in a record since its last time read. But they are unable to detect what column
or columns are changed.
You can get better answers for this if you ask a solution for concurrency issue in a SQL Server forum.
