Deleting records from table MVER

We are experiencing performance issues when adding data to table MVER. We have data on there that is over 5 years old which could be deleted. As we have not been able to find any standard program or process that carries out housekeeping on MVER we are considering writing an ABAP program to delete the records. Has anyone had any problems when deleting records from MVER or does anyone know of any reason why we should not delete these records in this way ?

Well, I wouldn't delet data from a standard SAP table based on information from the internete. I'd look at other alternatives.
Are you maintaining custom indexes on this table?
Are your database statistics up to date?
Consider a databse re-org.
I don't think simple inserts should cause a problem.

Delete records from tableA which are not in tableB

Table A contains milions of records which is the best way to delete records from tableA which are not in tableB
delete from tableA where empno not in (select empno from tableb)
or
delete from tableA where empno not exists (select empno from tableb
where b.empno=a.empno)
any help

Hi
If you can do this, do with this:
create table tableC
as select a.*
from tableA a,
(select empno from tableA
minus
select empno from tableB) b
where a.empno = b.empno;
drop table tableA;
rename table tableC to tableA;

Which i don't want to.
Is there any facility in BDC to put records on top which i want to delete?
Please guide me.

Hi,
While doing recording check for Filter button available for the table control, if it available then do the recording for the same.
Once it is done while passing the data from internal table put the value into Filter field.
Hope it resolves your issue.
Thanks & Regards.

One option is to identify the table and find out the location as the number of row which should be deleted from the table and then in the bdc program instead of postioning the cursor on the row 1(using the statement perform bdc_cursor ....(01)), replace the 01 with the row number.
Second option is that if a filter control is available for the table control, then filter the data each and every time with the material number to be deleted and then delete the first row.

Deleting Records from Referential Tables

Hi,
Can anyone help me in deleting records from tables in a hierarcial manner. For e.g C refers B and B refers A. I need to delete data from all three tables related to a where clause in A.I tried using User_constraints and User_cons_columns views. But i am not able to find a hierarchial delete statement.
Venkatesh

Did you look into the option of specifying ON DELETE CASCADE for your foreign key constraints. That way, if you delete a
row from the master table Oracle will automatically go and delete the child rows. Take a look at the following script.
Here, when I delete a row from table A for NUM = 1 the child rows from table B (WHERE num = 1) are automatically deleted.
drop table b
drop table a
create table a (num number, name varchar2(40))
create table b (num number, name varchar2(40))
alter table a add constraint pk_a primary key(num)
alter table b add constraint fk_b_num foreign key (num) references a(num) on delete cascade
insert into a values (1, 'Test#1')
insert into a values (2, 'Test#2')
insert into b values (1, 'Referes#1')
insert into b values (2, 'Referes#2')
select * from a
select * from b
delete from a where num = 1
select * from a
select * from b
Sridhar,
Thanks a lot for your help.My exact need was to delete records in 50 tables starting with the key table for a specific condition in the key table.
Assume table A has 100 records,B 200 records,C 150 records,D 400 records, etc
When i want to delete some records in table A, i will not be able to do that as child records exists in table B and this structure will carry on till that last table in my application. How do i delete those specific records

Delete records from internal table

hi all,
i want to delete records from intenal table which are starting with a particular starting number .

i want delete the records starting with 9 i.e. 90000 91000 92000.
Thanks in Adv

You can test this piece of code.
DATA:
i_tab TYPE STANDARD TABLE OF mara,
wa_tab TYPE mara.
wa_tab-matnr = '1000'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1002'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '1003'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '2001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '3001'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.
wa_tab-matnr = '4010'.
APPEND wa_tab TO i_tab.
CLEAR wa_tab.

Delete records from multiple table

Hi,
I need to delete records from multiple tables using a single delete statement. Is it possible ? If so please let me know the procedure.
Kindly Help.
Thanks,
Alexander.

Hi Tim,
Syntax of DELETE statement does not allow for multiple tables to be specified in this way. Infact, none of the DMLs allow you to specify table names like this.
Technically, there are other ways of deleting from multiple tables with one statement.
1. "Use a trigger":
What was probably meant by this is that you have a driving-table on which you create a on-delete trigger. In this trigger, you write the logic for deleting from other tables that you want to delete from.
This does mean a one-time effort of writing the trigger. But the actual DML operation of deleting from all the tables would be simply triggered by a delete on driving-table.
2. Dynamic SQL:
Write a PL/SQL code to open a cursor with table-names from which you want the data to be deleted from. In the cursor-for loop, write a dynamic SQL using the table-name to delete from that table.
3. Using Foreign-Key constraint with Cascade-Delete:
This I feel is a more 'cleaner' way of doing this.
Having to delete data from multiple tables means that there is some kind of parent-child relationship between your tables. These relationships can be implemented in database using foreign-key constraints. While creating foreign-key constraint give the 'on delete cascade' clause to ensure that whenever data is deleted from parent-table, its dependent data is deleted from child-table.
Using foreign-key constraint you can create a heirarchy of parent-child relationships and still your DELETE would be simple as you would only have to delete from parent-table.
IMPORTANT: Implementing foreign-key constraints would also impact other DML operations that you should keep in mind.

Deleting records from a recursive table query

Hi All,
I have the follow query, I would like to ask for your help, please: we use recursive tables for various purposes and one of them may have 100,000's records.
What would be the best approach to delete records from such a table?
I was thinking about two below, but any additional one will be more than welcome as well:
(1) I can DELETE FROM my_table WHERE my_table_id IN (SELECT my_table_id FROM my_table START WITH my_table_parent_id = X CONNECT BY PRIOR my_table_id = my_table_parent_id, but it means that I will run on my_table twice, no?
(2) I thought also to create a Foreign Key of my_table_id REFERENCES my_table_parent_id, but then I am afraid it will effect DML commands on that table.
Thank you in advance

Assuming you don't already have a foreign key constraint (as you described below) I don;t know any other way, let alone a more efficient way, to get the same results.
(2) I thought also to create a Foreign Key of my_table_id REFERENCES my_table_parent_id, but then I am afraid it will effect DML commands on that table.You're right; a foreign key constraint always costs a little whenever you do DML. Someone who knows your application and your system as well as you do will have to decide if the benefit of having accurate, consistent data justifies that additional cost. If you're not sure, I suggest you add the constraint.
One advantage of having a foreign key constraint is that you can create it with the "ON DELETE CASCADE" option. Then, if you simply say "DELETE FROM my_table WHERE my_table_patrent_id = X", all the descendants of those rows will automatically be deleted, exactly as you requested in (1) above.

Help needed writing trigger for deleting records from multipul tables

i am trying to write a trigger which would help me delete the record from 3 different tables
lets say i have table a , b and c
i an trying to write a trigger which would help me delete the same record from table a and c.
drop trigger az_zzz_trigger;
create trigger az_zzz_trigger
before INSERT or UPDATE or DELETE ON az_employ
FOR EACH ROW
BEGIN
IF DELETING then
delete from za_payroll
delete from az_salary_audit
end if;
end;
while executing this trigger all data of table za_payroll is delete.
what should i do so that only the record which i delete from az_employ gets deleted from az_payroll and az_salary_audit

Deleting records from compared tables...

Hi all,
I know there are a bunch of posts regarding this issue...but I don't see one that quite fits this scenario. I have two tables with the exact same structure...with key field matnr. I want to delete all of those records from table A where the material does NOT exist in table B. Is there a terse way to accomplish this?

Suresh and Ravi,
you are real good contributors to this forum and i like that.
Not that you give a LOT of answers, your answers even porve quality.
BUT i have one thing. People asking questions here are sometimes not TOO used to the ABAP syntax and other concepts.
SAP noticed that themselves and made some concepts "obsolete", to get a code which is better to read. Especially for newbies.
And well HEADER LINES are obsolete by now.
People not beeing really used to ABAP will have really big Problems in reading things like:
Loop at itab.
endloop.
or even harder:
modify itab.
this shall not be critic in any way, but rather a suggestion on how you can help the better. Accoring to your number of posts thats what you actually want.
thx for convenience.
