How to delete the matching records from two internal tables

Hi ,
I have two internal tables say A and B of the same type. If A has 10 records and B has 4 records , I want to delete the 4 records in B from A .
loop at B into wa .
delete A where key = wa - key .
endloop.
takes a long time if the table B is huge. how can I improve the performance.
Thanks.
Gayathri

Hi Gayathri,
You could try field-symbols. It reduces the data transfer from the internal table B to the work area.
field-symbols <fs_itab_b> like line of B.
loop at B assigning <fs_itab_b>.
delete A where key = <fs_itab_b>?-key.
endloop.

How to delete the single record from the ODS

HI,
I want to DELETE the particular record from ODS.. how to delete that..
plz give me the solution.. it's urgent..
with regards
@jay

Hi Prakash,
You can delete a particular record from ODS by specifying the key field name in Selective deletion button available in Contents tab in the manage screen of ODS. But it will only delete the record from the active data table and not from the Change log and new data table . You should be very carefull if you are doing in Production system as there is chance of deleting other records accidentally.
Go to Selective deletion button - > Click on delete selection -> Enter the key field values of the record you want to delete-> Press save button to save as Variant -> Go back and click on selection button -> Chosse the background job type -> Click on start button.

Prakash

How do I extract matching records from two tables?

I'm trying to extract client records from our client database to put together a very targeted email campaign. As an example, the result I want is a list of names and email addresses of those clients who have a record in our system, have not had a visit in our clinic in the last year, and live within 200 miles of our clinic. I can capture the first two criteria in one extract, and the second in another. I can then import those as tab delimited data into Numbers. What I then need to do is create a third table that represents ONLY those records that exist in both tables.
Can someone tell me if this is possible and if so, how to do it?
I'd be very appreciative of any help, thank you.

You can create a column that generates a serial marker on the table from which you want to transfer the data, making all the names that also appear on the other table. Not that the formula will mark only exact matches.
Here's a short example:
Table 1 on the left, is one of the two tables imported from the tab delimited data files. It has other data, but only the names in column A are used to identify records appearing on both tables.
Table 2 on the right, contains the names and other data (represented by the email addresses in column B), to be transferred to the third table.
Column C of this table contains the formula that counts off the rows containing names appearing on both tables. The version below is in C2, and is filled down to the end of the column.
=IF(COUNTIF(Table 1 :: $B,A2)>0,MAX($C$1:C1)+1,"")
Note that jane Doe is not counted (or transferred) as her name is recorded differently on the two tables.
Table 3 is the results table. It contains one formula for each column to be transferred from Table 2 to Table 3.
A2: =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $A))
B2: =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $B))
Regards,
Barry
EDIT: I was working in Numbers '09 when developing this, and got the following warning when I saved a copy as an iWork '08 document:
Referencing row or column ranges that include header or footer cells isn't supported. The formula references were updated to exclude header and footer cells.
The formulas in Table 2::C2 references C1. You may have to ensure that Table 2 does not include a header row.
B.
EDIT2: A check on the file in Numbers '08 showed no apparent change to the formula, and editing Jane Doe's name on table 1 resulted in her name being added to Table 3.

How to delete the child record from the database

how to delete a parent and child record from the database can we do it in the servlet and my database is oracle

I'm not sure I understand the question but you could certainly use the JDBC API from within your servlet to access and modify a DB. You could also use an EJB layer to access your DB and accomplish the same tasks.

Get the Common from Two Internal Tables with same structure

Hi ,
I need to get the Common data from Two Internal Tables with same structure with using the looping method.
For e.g.
I have two internal table say ITAB1 and ITAB2.
ITAB1 has values A,B,C,D,E,F
ITAB2 has values A,H,B,Y,O
Output at runtime should be : A,B

Hi mohit,
1. If u want to compare all fields,
   for matching purpose,
   then we can do like this.
2.
report abc.
data : a like t001 occurs 0 with header line.
data : b like t001 occurs 0 with header line.
loop at a.
LOOP AT B.
    IF A = B.
      WRITE :/ 'SAME'.
    ENDIF.
endloop.
ENDLOOP.

How to handle an update of the same record from two different user JSP

how do you handle an update of the same record from two different users in JSP... if one person updates the record from one drop downs should be updated as well.. is the possible.

I'm not sure whether I understand your question. If one user changes a record then you would like other users to see those changes. Normally those changes will be visible to other users when they refresh their browser, after the first user has committed changes to the record. I you want to be sure that the same row isn't updated at the same time by to different user, you need to configure some locking (pessimistic locking) - this depends of what technology you use. In EJB3 pessimistic locking is performed by adding a version to every entity object. If you are using ADF, the framework is able to handle either pessimistic or even optimistic locking.
If you want the changed row to be updated in other users browsers without any user interaction by these users, you should take a look at Reverse Ajax (ex. DWR http://ajaxian.com/archives/reverse-ajax-with-dwr) - or Ajax in general. But you will never get a realtime solution, where changes is visible in other users browsers right after each record update.

How to handle an update of the same record from two different user in JSP

how to handle an update of the same record from two different user
how do you handle an update of the same record from two different users in JSP... if one person updates the record from one drop downs should be updated as well.. is the possible.

Usually, if two users try to update the same row at the same time, you want the first to commit to succeed, and when the second commits, they should fail with the error that the row was being concurrently updated. They you may want to show them the new row values and give them the opportunity to merge their values with the new row values...
How can you achieve this? Google optimistic locking.

DELETE THE MATCHED RECORDS IN DB2 TABLE

DELETE THE MATCHED RECORDS IN DB2 TABLE

DB2 table db2_emp(c1 key,c2,c3,c4)
records:1 2 5 6 7 8
Both tables having same structure
Matched records : 1 2
1.Delete the matched records in db2 table : 1 2 (without using truncate option for DB2 in Anywhere)
2.Finally Load all records in sql server(Because duplicate records in db2 already removed so no duplicates occured)
3.NEED final OUTPUT AS:db2 table: 5 6 7 8 1 2 3 4
Note:
1.DB2 truncate doesn't used
2.STARING AREA: ORACLE
3.SQLSERVER AND DB2 CLOSED ENVIRONMENT DOESN'T USED AS STAGING AREA.
HOW MANY INTERFACES AND PROCEDURES SHOULD BE CREATE? WHAT ARE THEY?
HOW TO REACH MY REQUIREMNT?
Answer provider is more appricatable.
Thanks in advance.

1st option
See in this scenario you can use two interface and one procedure step.
1st interface-->poricedure-->2nd interface
1st interface will bring data to oracle staging-->then procedure will delete matched record from target using keys--->3rd interface will simple insert the the data in oracle staging.
2nd option
Insted of deleting the target matched records, you just update target matched record with latest records in your staging oracle.You can use IKM Merge
Thanks

How to delete the duplicate data from PSA Table

How to delete a particula record from InfoObject

Dear All,
I got some problem situations and would like some suggestions from any of you.
<b>Problem detail</b>- one process chain was failed due to could not activate an ODS-A
- ODS-A and ODS-B contained InfoObject-0BP_GUID
- errors were found and referred to the InfoObject-0BP_GUID.
- The errors referred to one record composed of incorrect data. I still wondered where it came from since normally, 0BP_GUID keeps only guid.
I'd like to delete the incorrect record.But I do not want any impact to InfoProviders.
I'm not sure how to resolve this case. This has to be very carefully managed because it happened on production system.
Actually, I did find one thread in this forum "Delete SID table content". But I'm not sure whether it could be applied to my case.
Any suggestion would be appreciated.
Thank you very much.
-WJ-

Unfortunately you cant delete data without inpacting the data in the. This is how BW works and you will appreciate this because youur transaction data is secured and you wont face any data issues later on. Let me give you an example. Lets sa your ODS or cube stored sales data and in the ODS you have sales org, customer and amount. When you run the report, data is read from this cube /ods, but to fetch the master data it goes to the master data tables via SID. When the transaction data gets loaded and when you try to delete a record in master data, it will let you do.
If you still wish to do, proceed as follows:
1. Delete the data in cube first.
2. Delete the particular record from the master data table.3
3. Reload the data to the ODS / cube.
Without deleting the transaction data in the ODS / Cube the system wont let you delete the data in master data and you will get any of the following messages.
(a) " not all master data could be deleted
(b) "the master data can not be deleted".
