Processing changes in Syabse database table

Can someone help me understand best way to process changes on a database table using XI?
I'm crrently doing this using webmethods where webmethods generates a xml document whenever a row is inserted in a database using adapter notification mechanism. Then I can process this document by calling webservice.

Thx Naveen,
e.g. I insert a customer record in Sybase system, I would like that XI interface would insert same customer in SAP or another Database system and this should happen as a result in insert in Sybase table.
Other way I can already achive this is by having XI look in a sybase table periodicaly and see if there are new rows of data added to the table since it last looked and then process those rows accordingly. I don't want to use this approach since it keeps looking at certain intervals and most of the time there won't be anything for it to process. Also when there is something to process, it will not be processed instanteneously but only when XI looks at the table next time around.
This is whole debate about pushing data v/s polling for changes. I would like to push the info at the time data is inserted in sybase table instead of having to poll for it.
appreciate your response.

Help with creating a sql file that will capture any database table changes.

We are in the process of creating DROP/Create tables, and using exp/imp data into the tables (the data is in flat files).
Our client is bit curious to work with. They do the alterations to their database (change the layout, change the datatype, drops tables) without our knowing. This has created a hell lot of issues with us.
Is there a way that we can create a sql script which can capture any table changes on the database, so that when the client trys to execute imp batch file, the sql file should first check to see if any changes are made. If made, then it should stop execution and give an error message.
Any help/suggestions would be highly appreciable.
Thanks,

Just to clarify...
1. DDL commands are like CREATE, DROP, ALTER. (These are different than DML commands - INSERT, UPDATE, DELETE).
2. The DDL trigger is created at the database level, not on each table. You only need one DDL trigger.
3. You can choose the DDL commands for which you want the trigger to fire (probably, you'll want CREATE, DROP, ALTER, at a minimum).
4. The DDL trigger only fires when one of these DDL commands is run.
Whether you have 50 tables or 50,000 tables is not significant to performance in this context.
What's signficant is how often you'll be executing the DDL commands on which the trigger is set to fire and whether the DDL commands execute in acceptable time with the trigger in place.

Change of structure of database table

A custom database table has been created and is already in use by 10 programs. Now a new requirement has come to add a field i.e. a check box to the database table to be used by one of the 10 programs. Can we change the structure of the database table after activating it and when the table is in use? Please provide me inputs on this.
Thanks and regards
Radhika

Yes. U can change it. But I suggest u to do it through the process of 'Append Structure'.
If u have any probelm after changing follow this process.

How to change a field of type CHAR of a database table to DATS

Dear ABAP experts,
I have a database table: ZLT_aztnew with fields M1, M2, K1, K2, A1, A2, P1, P2, S2, D1, D2, STD, BES. All these fields are of type 'Character'. except D2 which is of type DATS. The field D1 is date and is in format DD.MM.YYYY.
I want to convert this field D1 to type DATS so that I can use a date range through 'selection option' to select other data of other fields (M1, M2, K1, K2, A1, A2, P1, P2, S2, D1, STD, BES.) related to field D1 from the database table Zlt_aztnew.
How should I introduce this change (CONVERSION OF D1 CHAR to DATS in the .AZT file upload code itself.
Problem: If I define D1 as Type DATS in database table ZLT_AZTNEW then the UPLOAD fails.
The AZT file upload code is:

Open Hub - Change from File to Database table

Hello Experts;
I want to change the Open Hub Service that we create from File to Database table.
We are using the Delta Update. However, after I change the Open Hub, Activate the transformation and DTP, when I run it, I don't have any value in the table.
If I run a new delta into my cube, in the table I only get the data from delta.
Can anyone knows how to upload all the requests that I have in my cube for the first time I run the delta DTP?
Thanks and regards;
Ricardo

Create a new Full DTP and execute, so that you can dump all of the current contents of the InfoCube into the table and push/pull that table to the target prior to the next delta retraction.

Tracking changes in database tables

Hi,
I have a couple of database tables on which more than 20 people work each day, throughout the day. I have the requirement of tracking each and every change made on any row of the table.
For example, If a user accesses a specific row, and updates, or deletes it, i need to keep a track of the userid of the user who did it.
Is that possible?

Hi Bharat,
If they are Z tables i.e custom tables then you can incorporate two more fields userid and time. Now goto Table maintanence generator through SE11.Then select Environment->Modification->events. Now in the next screen select F4 for first field to select the event i.e when your code has to be executed.Then give a new form name and click on editor icon. write your code here. When ever a user changes any record his name will be included in user id and sy-uzeit in time field. This way you can track who has changed the record. Other option is activating table changes recording by selecting "LogChanges " check box in technical settings of table.and profile parameter rec/client should also be switched on. Then you can see your table changes in SCU3 transaction. Hope this helps.

Track of table changes in a database

how to keep track of table changes in a database.
Some records have been deleleted, is there away of seeing that change.

basically, if you havn't already set up a mechanism to track these sorts of changes, they are already lost.
there are a number of things you can do. one method that we use is a trigger on the table to insert a record into an audit table for every row that gets changed or deleted.
oracle has some other built in auditing tools that I'm not familiar with though.

Change the data in fieldcat and update the database table in alv oops

Hi,
my requirement is i have displayed a fieldcat in change mode and when i change the data and click on save it has to be updated the database table..
this has to be done using alv oops...

Hi,
This code will reflect all the changes into the internal table that is being displayed.
* to reflect the data changed into internal table
      DATA : ref_grid TYPE REF TO cl_gui_alv_grid. "new

            e_grid = ref_grid.
      ENDIF.
      IF NOT ref_grid IS INITIAL.
        CALL METHOD ref_grid->check_changed_data.
      ENDIF.
Now after this code is executed the internal table is modified as per the changes done in alv output.
Now you can use this internal table to update the database table.
Hope this helps you.

Will any change in tempdb database affect the user defined tables?

Will any change in tempdb database affect the user defined tables?
Suppose I have deleted a table from system database tempdb, will it effect the user defined tables?
Anujit Karmakar Sr. Software Engineer

The short answer is no; deleting a table from tempdb will not affect user databases.
Of course I could make up some connection between the two that you haven't described. For example, if a stored procedure created a temporary table, and was busy using it when you deleted it, the deletion could cause unexpected behavior in the user database,
which could affect some table data.
Also, some system actions in user databases can store data in tempdb temporarily. But you aren't likely to be talking about system usages of tempdb.
