How to delete some date in target table at a mapping?

How to delete some date in target table at a mapping?
I extract date from source tabel into target table,
but before extract date I want to delete some date from target?
how to do?

Just to change a bit of terminology in the reply, within the mapping, click on operator properties and choose TRUNCATE/INSERT.
Note that truncate is dependent on constraints, so you probably must disable those before doing this. You can of course do DELETE/INSERT...

How to delete some data from GLPCA table

Dear Friends,
We have extracted some data in GLPCA table via the ECPA component. We
want to delete these records ( Doc type and Posting date is known).
However we do not want other data already existing the GLPCA to be
deleted. Is there some Std SAP Trx for deletion of partial/select data
from EIS tables.
Please explain us clearaly how we can delete these records.
Your quick reply for this issue is highly appreciated.
Thanks & Regards,
Naveen Kumar.

Hello,
Please check the use of the report ZDELETE_PCA_DATA_BUKRS (mentioned in the SAP note 1174360), to delete totals from GLPCT.
I am not sure of any deletion reports for GLPCA table.
If you open the Source code of this program, you can see the following information :
"This report provides a possibility to delete actual and plan
*& postings on company code level as an alternative for transaction
*& 0KE1."
I do not have much information on this report as, personally I haven't used this anytime. Please run in 'Test Run' mode first and look for the results.
I hope this helps.
Thanks and regards,
Suresh Jayanthi.

How to delete the data from partition table

Hi all,
Am very new to partition concepts in oracle..
here my question is how to delete the data from partition table.
is the below query will work ?
delete from table1 partition (P_2008_1212)
we have define range partition ...
or help me how to delete the data from partition table.
Thanks
Sree

delete from table1 partition (P_2008_1212)This approach is wrong - as Andre pointed, this is not how partition tables should be used.
Oracle supports different structures for data and indexes. A table can be a hash table or index organised table. It can have B+tree index. It can have bitmap indexes. It can be partitioned. Etc.
How the table implements its structure is a physical design consideration.
Application code should only deal with the logical data structure. How that data structure is physically implemented has no bearing on application. Does your application need to know what the indexes are and the names of the indexes,in order to use a table? Obviously not. So why then does your application need to know that the table is partitioned?
When your application code starts referring directly to physical partitions, it needs to know HOW the table is partitioned. It needs to know WHAT partitions to use. It needs to know the names of the partitions. Etc.
And why? All this means is increased complexity in application code as this code now needs to know and understand the physical data structure. This app code is now more complex, has more moving parts, will have more bugs, and will be more complex to maintain.
Oracle can take an app SQL and it can determine (based on the predicates of the SQL), which partitions to use and not use for executing that SQL. All done totally transparently. The app does not need to know that the table is even partitioned.
This is a crucial concept to understand and get right.

How to export some data from the tables of an owner with integrity?

Hi to all,
How to export some data from the tables of an owner with integrity?
I want to bring some data from all tables in a single owner of the production database for development environment.
My initial requirements are: seeking information on company code (emp), contract status (status) and / or effective date of contract settlement (dt_liq_efetiva) - a small amount of data to developers.
These three fields are present in the main system table (the table of contracts). Then I thought about ...
- create a temporary table from the query results table to contract;
- and then use this temporary table as a reference to fetch the data in other tables of the owner while maintaining integrity. But how? I have not found the answer, because: what to do when not there is the possibility of a join between the contract and any other table?
I am considering the possibility of consulting the names of tables, foreign keys and columns above, and create dynamic SQL. Conceptually, something like:
select r.constraint_name "FK name",
r.table_name "FK table",
r.column_name "FK column",
up.constraint_name "Referencing name",
up.table_name "Referencing table",
up.column_name "Referencing column"
from all_cons_columns up
join all_cons_columns r
using (owner, position), (select r.owner,
r.constraint_name fk,
r.table_name table_fk,
r.r_constraint_name r,
up.table_name table_r
from all_constraints up, all_constraints r
where r.r_owner = up.owner
and r.r_constraint_name = up.constraint_name
and up.constraint_type in ('P', 'U')
and r.constraint_type = 'R'
and r.owner = 'OWNERNAME') aux
where r.constraint_name = aux.fk
and r.table_name = aux.table_fk
and up.constraint_name = aux.r
and up.table_name = aux.table_r;
-- + Dynamic SQL
If anyone has any suggestions and / or reuse code to me thank you very much!
After resolving this standoff intend to mount the inserts in utl_file by a table and create another program to read and play in the development environment.

Well, I am working with release 9.2.0.8.0. But the planning is migrate to 10g this year. So my questions are:
With Data Pump can export data just from tables owned for me (SCHEMAS = MYOWNER) parameterizing the volume of data (SAMPLE) and filters to table (QUERY), right? But parameterizing a contract table QUERY = "WHERE status NOT IN (2,6) ORDER BY contract ":
1º- the Data Pump automatically searches for related data in other tables in the owner? ex. parcel table has X records related (fk) with Y contracts not in (2,6): X * SAMPLE records will be randomly exported?
2º- for the tables without relation (fk) and which are within the owner (MYOWNER) the data is exported only based on the parameter SAMPLE?
Once again, thank you,

How to delete rows in the target table using interface

plz tell me how to achieve this?
Regards,

For this do we need to apply CDC?
I am not clear on how to delete rows under target, Can you please share the steps to be followed.If you are able to track the deletes in your source data then you dont need CDC. If however you cant - then it might be an option.
I'll give you an example from what im working on currently.
We have an ODS, some 400+ tables. Some are needed 'Real-Time' so we are using CDC. Some are OK to be batch loaded overnight.
CDC captures the Deletes no problem so the standard knowledge modules with a little tweaking for performance are doing the job fine, it handles deletes.
The overnight batch process however cannot track a delete as its phyiscally gone by the time we run the scenarios, so we load all the insert/updates using a last modified date before we pull all the PK's from the source and delete them using a NOT EXISTS looking back at the collection (staging) table. We had to write our own KM for that.
All im saying to the OP is that whilst you have Insert / Update flags to set on the target datastore to influence the API code, there is nothing stopping you extending this logic with the UD flags if you wish and writing your own routines with what to do with the deletes - It all depends on how efficient you can identify rows that have been deleted.

How to delete select data in the table control

this problem makes me headache.
I am new to labview, when a table shows some data. many rows and column. how can delete on row which I selected. the other rows are remain no change.
I really need help.thanks in advance. It is better to attach the program.my labview is 2009
Solved!
Go to Solution.

Hi,
You can do it with a table control as well. Check out the attached VI. To delete a row, Run the VI, just right click the row and click "Delete Row". To get back the default values, click reinitialize.

How to delete all data in a table

What's the best way to delete all of the data from a table? I wan't to do a data wipe of our database to eliminate all of the test data we've been putting into it over the last few months.
I've tried using: DELETE FROM TABLENAME; but killed SQL+ after it ran for 13 hours and still wasn't done. There are approximately 900,000 records in this table and I would prefer not to drop/recreate the table because of the various dependencies within the database.
Any suggestions would be appreciated.
Thanks,

Try the TRUNCATE TABLE command. That's quick and easy.
e.g.
TRUNCATE TABLE mytable;

How to delete PSA Data from any Table

Pls specify the steps to delete PSA Data from any specific table.

You can delete the PSA requests manually one by one as specified in the previous posts.
You can also trigger the deletion of PSA periodically by using Process chain.
'Deletion of PSA request' is the process type that need to be used.
By this way you can delete all the PSA requests of the table, that are older than certain number of days.
you can also schedule the PSA deletion for more than one table at a time, by including the tables in the same Process chain.

How to reduce the size of file after delete some datas?

Hi,
What BDB release are you using? If it's one of the latest releases, then what you are looking for is the DB->compact() method:
http://download.oracle.com/docs/cd/E17076_01/html/api_reference/C/dbcompact.html
The DB->compact() method compacts Btree, Hash, and Recno access method databases, and optionally returns unused Btree, Hash or Recno database pages to the underlying filesystem. Please let me know if it helps.

How to delete master data of materials from sap tables

how to delete master data of materials from sap tables...its needed now.
i know its not recommended but still we need to do this. give me the best possible approach.
regards,
suneetha

Hi,
I would suggest you not to write your own code to delete the entries.
BAPI_MATERIAL_DELETE, this would mark all materials selected for deletion. But still the material would exist in SAP.
Another solution: Delete a material manually and in another session execute the transaction SM04. This would display the tables which get locked when you do the operation, Then you can write your own code to delete the material numbers from all the related tables.

not too sure what you mean, perhaps you could supply a table description and some sample data
but, consider
delete from table_1 where column_1 is null
